Telco cloud deployment tracker: What is happening with SD-WAN in 2023?

What is happening with SD-WAN in 2023?

The state of the SD-WAN market has changed significantly since the 2010s, when it emerged as prominent driver of telco cloud activity, centred on North America. SD-WAN remains strong, with nearly a quarter of telco cloud deployments in 2022 having SD-WAN as the primary purpose, and has spread across the globe.

Every update of the Telco cloud deployment tracker includes a review of the confirmed or completed telco cloud deployments up to the end of the preceding quarter, and a deep dive into a significant trend revealed in the data. SD-WAN, SASE, and the evolution towards NaaS is in the spotlight in this update.

SD-WAN: A virtualisation success story

SD-WAN is an example of where a technology trend – Network Functions Virtualisation and Software Defined Networking (NFV and SDN) – fed directly into a successful commercial product. It comprises a bundle of Virtualised Network Functions (VNFs), such as routing, WAN optimisation and firewall, placed under centralised SDN control to deliver optimised, application-specific traffic management and prioritisation across the multi-domain, multi-technology enterprise network.

Initially developed and marketed as an overlay service by ISVs – a purely software-based service managed independently of the underlying network platforms – SD-WAN started to be widely delivered by telcos from 2017 as part of their managed enterprise networking portfolios. Deployments in this first wave of telco SD-WAN peaked in 2018, with 45 deployments focused on SD-WAN in that year.

SASE is a response to the increasing cloudification of SD-WAN

Telcos have not driven innovation in the SD-WAN field. In terms of number of directly served enterprise customers and technology evolution, vendors dominate. Secure Access Service Edge (SASE) is one such vendor-led solution. It combines SD-WAN with several cloud-based security functions designed to protect against cyber attacks as network traffic crosses the borders between private and public networks and clouds.

SASE first emerged as a distinct offering in July 2019; but telcos lagged, and the first deployments by telcos were recorded only in 2021.

The increased focus on cloud-delivered security reflects the growing cloudification of WAN services themselves, with larger enterprises running application workloads and traffic across multiple clouds and bypassing the telco WAN altogether.

MWC 2023: You are now in a new industry

The birth of a new sector: “Connected Technologies”

Mobile World Congress (MWC) is the world’s biggest showcase for the mobile telecoms industry. MWC 2023 marked the second year back to full scale after COVID disruptions. With 88k visitors, 2,400 exhibitors and 1,000 speakers it did not quite reach pre-COVID heights, but remained an enormous scale event. Notably, 56% of visitors came from industries adjacent to the core mobile ecosystem, reflecting STL’s view that we are now in a new industry with a diverse range of players delivering connected technologies.

With such scale It can be difficult to find the significant messages through the noise. STL’s research team attended the event in full force, and we each focused on a specific topic. In this report we distil what we saw at MWC 2023 and what we think it means for telecoms operators, technology companies and new players entering the industry.

STL-Partners-MWC23-research-team

The diversity of companies attending and of applications demonstrated at MWC23 illustrated that the business being conducted is no longer the delivery of mobile communications. It is addressing a broader goal that we’ve described as the Coordination Age. This is the use of connected technologies to help a wide range of customers make better use of their resources.

The centrality of the GSMA Open Gateway announcement in discussions was one harbinger of the new model. The point of the APIs is to enable other players to access and use telecoms resources more automatically and rapidly, rather than through lengthy and complex bespoke processes. It starts to open many new business model opportunities across the economy. To steal the words of John Antanaitis, VP Global Portfolio Marketing at Vonage, APIs are “a small key to a big door”.

Other examples from MWC 2023 underlining the transition of “telecommunications” to a sector with new boundaries and new functions include:

  • The centrality of ecosystems and partnerships, which fundamentally serve to connect different parts of the technology value chain.
  • The importance of sustainability to the industry’s agenda. This is about careful and efficient use of resources within the industry and enabling customers to connect their own technologies to optimise energy consumption and their uses of other scarce resources such as land, water and carbon.
  • An increasing interest and experimentation with the metaverse, which uses connected technologies (AR/VR, high speed data, sometimes edge resources) to deliver a newly visceral experience to its users, in turn delivering other benefits, such as more engaging entertainment (better use of leisure time and attention), and more compelling training experiences (e.g. delivering more realistic and lifelike emergency training scenarios).
  • A primary purpose of telco cloud is to break out the functions and technologies within the operators and network domains. It makes individual processes, assets and functions programmable – again, linking them with signals from other parts of the ecosystem – whether an external customer or partner or internal users.
  • The growing dialogues around edge computing and private networks –evolving ways for enterprise customers to take control of all or part of their connected technologies.
  • The importance of AI and automation, both within operators and across the market. The nature of automation is to connect one technology or data source to another. An action in one place is triggered by a signal from another.

Many of these connecting technologies are still relatively nascent and incomplete at this stage. They do not yet deliver the experiences or economics that will ultimately make them successful. However, what they collectively reveal is that the underlying drive to connect technologies to make better use of resources is like a form of economic gravity. In the same way that water will always run downhill, so will the market evolve towards optimising the use of resources through connecting technologies.

The state of telco transformation

There are two possible interpretations of the phrase “the state of transformation”:

  1. How is transformation going at telcos, i.e. where are telcos on the path to transformation
  2. The condition of transformation, i.e. what does it mean to be in the process of transforming.

Over the summer of 2022, STL Partners carried out nine in-depth interviews with telco employees that were involved in influencing, coordinating, or implementing large change projects at their organisations. These change makers came from various disciplines: Strategy, HR, Transformation project management, Networks, Technology, as well as Research. Our first intention was to illuminate the first interpretation (where are telcos on the path to
transformation), but our findings suggest that transformation paths (and indeed end states) are unique to each operator, making it difficult to compare progress between telcos.

No one path – overlapping changes in multiple areas

Source: STL Partners

We have mainly come away with findings on the latter point – identifying the types of change initiatives underway and the challenges that change-makers are encountering on their journeys.

This report brings together insights from our interviews, contextualised with further information from secondary sources and ongoing conversations with operators, to give a sense of what telcos mean when they talk about transformation and what their challenges are in becoming more adaptable as organisations to find growth.

Why is Transformation important to telcos

Far from being an irrelevant or out-dated concept, telcos continue to transform internally. Transformation is understood as a deep change initiative that might involve a shift in foundational technology or a broad-based change in the way an organisation does things, i.e. the culture, processes and the people required – or both.

Most commonly, transformation involves the integration of digital technologies/tools (e.g. cloud, automation, data analytics) into organisational processes to improve business outcomes – with an impact on ways of working (“digital transformation”).

Some telcos talk about transformation in terms of functional initiatives (e.g. IT modernisation), ostensibly affecting a subset of the business, while others talk about transformation from an organisation-wide perspective (e.g. a change in culture like Lean Six Sigma).

The common feature between telco narratives about transformation is that they are motivated by
trying to improve the organisation’s ability to achieve their future vision. This could involve:

  • Making the business more efficient,
  • Creating new value/finding new revenues,
  • Improving outcomes for customers.

Transformations are also undertaken when the vision changes (e.g. when a new leader takes the helm). STL observes that interview respondents described technology-led transformations as aligned to efficiency benefits in the first instance, while organisation-led change was more aligned to responsiveness, particularly in relation to customer needs (improving outcomes). Respondents tended to describe combined technology- and organisation-led change initiatives when there was an ambition to do new things/create new value for customers.

The meaning of transformation – activities cited in interviews

Source: STL Partners

Respondents also mentioned:

  • Transformation in the context of the industry, particularly the possibility that new technologies may change the shape of an industry (e.g. tech companies may find it easier to enter telecoms with their technology capabilities, while telcos may find it difficult to extend services up the technology value chain).
  • The enterprise opportunity represented by digital transformation services.

These were not topics for further exploration in our interviews. Industry transformation is a topic for STL’s Executive Briefing Service – however the threat of industry disruption can and should be an inspiration for corporate transformation. Digital transformation services are covered in our Enterprise stream.

Telco Cloud Deployment Tracker: Deploying NFs on public cloud without losing control

In this update, we present a review of telco cloud deployments for the whole of 2022 and discuss trends that will shape the year ahead. Fewer deployments than expected were completed in 2022. The main reason for this was a delay in previously announced 5G Standalone (SA) core roll-outs, for reasons we have analysed in a previous report. However, we expect these deployments to be largely completed in 2023. 

We also review deployments of NFs on the public cloud in 2022. While few in number, they are significant in scope, and illustrate ways in which telcos of different types can deploy NFs on public cloud while retaining control over the management and ongoing development of those NFs.

CNFs on the public cloud: Recent deployments illustrate how to avoid hyperscaler lock-in

Few telcos have yet deployed critical network functions on the hyperscale cloud, as discussed in this report. However, significant new deployments did go live in 2022, as did tests and pilots, involving all three hyperscalers:​

Recent deployments and trials of CNFs on public cloud

Source: STL Partners

In our recently published Telco Cloud Manifesto 2.0, we argued that telcos thinking of outsourcing telco cloud (i.e. both VNFs/CNFs and cloud infrastructure) to hyperscalers should not do so as a simple alternative to evolving their own software development skills and cloud operational processes. In order to avoid a potentially crippling dependency on their hyperscaler partners, it is essential for operators to maintain control over the development and orchestration of their critical NFs and cloud infrastructure while delivering services across a combination of the private cloud and potentially multiple public clouds. In contrast to a simple outsourcing model, the deployments on public cloud in 2022 reflect different modes of exploiting the resources and potential of the cloud while maintaining control over NF development and potential MEC use cases. The telcos involved retain control because only specific parts of the cloud stack are handed over to the hyperscale platform; and, within that, the telcos also retain control over variable elements such as orchestration, NF development, physical infrastructure or the virtualisation layer.

In this report, we discuss the models which the telcos above have followed to migrate their network workloads onto the public cloud and how this move fits their overall virtualisation strategies.

The Telco Cloud Manifesto 2.0

Nearly two years on from our first Telco Cloud Manifesto published in March 2021, we are even more convinced that going through the pain of learning how to orchestrate and manage network workloads in a cloud-native environment is essential for telcos to successfully create new business models, such as Network-as-a-Service in support of edge compute applications.

Since the first Manifesto, hyperscalers have emerged as powerful partners and enablers for telcos’ technology transformation. But telcos that simply outsource to hyperscalers the delivery and management of their telco cloud, and of the multi-vendor, virtualised network functions that run on it, will never realise the true potential of telco cloudification. By contrast, evolving and maintaining an ability to orchestrate and manage multi-vendor, virtualised network functions end-to-end across distributed, multi-domain and multi-vendor infrastructure represents a vital control point that telcos should not surrender to the hyperscalers and vendors. Doing so could relegate telcos to a role as mere physical connectivity and infrastructure providers helping to deliver services developed, marketed and monetised by others.

In short, operators must take on the ‘workload’ of transforming into and acting as cloud-centric organisations before they shift their ‘workloads’ to the hyperscale cloud. In this updated Manifesto, we outline why, and what telcos at different stages of maturity should prioritise.

Two developments have taken place since the publication of our first manifesto that have changed the terms on which telcos are addressing network cloudification:

  • Hyperscale cloud providers have increasingly developed capabilities and commercial offers in the area of telco cloud. To telcos uncertain about the strategy and financial implications of the next phase of their investments, the hyperscalers appear to offer a shortcut to telco cloud: the possibility of avoiding doing all the hard yards of developing the private telco cloud, and of evolving the internal skills and processes for deploying and managing multi-vendor VNFs / CNFs over it. Instead, the hyperscalers offer the prospect of getting telco cloud and VNFs / CNFs on an ‘as-a-Service’ basis – fundamentally like any other cloud service.
  • In April 2021, DISH announced it would build its greenfield 5G network with AWS providing much of the virtual infrastructure layer and all of the physical cloud infrastructure. In June 2021, AT&T sold its private telco cloud platform to Microsoft Azure. In both instances, the telcos involved are now deploying mobile core network functions and, in DISH’s case, all of the software-based functions of its on a hyperscale cloud. These events appear superficially to set an example validating the idea of outsourcing telco cloud to the hyperscalers. After all, AT&T had previously been a champion of the DIY approach to telco cloud but now looked as though it had thrown in the towel and gone all in with outsourcing its cloud from Azure.

Two main questions arise from these developments, which we address in detail in this second Manifesto:

  • Should telcos embarked or embarking on a Pathway 2 strategy outsource their telco cloud infrastructure and procure their critical network functions – in whole or in part – from one or more hyperscalers, on an as-a-Service basis?
  • What is the broader significance of AT&T’s and DISH’s moves? Does it represent the logical culmination of telco cloudification and, if so, what are the technological and business-model characteristics of the ‘infrastructure-independent, cloud-native telco’, as we define this new Pathway 4? Finally, is this a model that all Pathway 3 players – and even all telcos per se – should ultimately seek to emulate?

In this second Manifesto, we also propose an updated version of our pathways describing telco network cloudification strategies for different sizes and types of telco to implement telco cloud. We now have four pathways (we had three in the original Manifesto), as illustrated in the figure below.

Telco Cloud Deployment Tracker: Will vRAN eclipse pure open RAN?

Is vRAN good enough for now?

In this October 2022 update to STL Partners’ Telco Cloud Deployment Tracker, we present data and analysis on progress with deployments of vRAN and open RAN. It is fair to say that open RAN (virtualised AND disaggregated RAN) deployments have not happened at the pace that STL Partners and many others had forecast. In parallel, some very significant deployments and developments are occurring with vRAN (virtualised NOT disaggregated RAN). Is open RAN a networking ideal that is not yet, or never will be, deployed in its purest form?

In our Telco Cloud Deployment Tracker, we track deployments of three types of virtualised RAN:

  1. Open RAN / O-RAN: Open, disaggregated, virtualised / cloud-native, with baseband (BU) functions distributed between a Central Unit (CU: control plane functions) and Distributed Unit (DU: data plane functions)
  2. vRAN: Virtualised and distributed CU/DU, with open interfaces but implemented as an integrated, single-vendor platform
  3. Cloud RAN (C-RAN): Single-vendor, virtualised / centralised BU, or CU only, with proprietary / closed interfaces

Cloud RAN is the most limited form of virtualised RAN: it is based on porting part or all of the functionality of the legacy, appliance-based BU into a Virtual Machine (VM). vRAN and open RAN are much more significant, in both technology and business-model terms, breaking open all parts of the RAN to more competition and opportunities for innovation. They are also cloud-native functions (CNFs) rather than VM-based.

2022 was meant to be the breakthrough year for open RAN: what happened?

  • Of the eight deployments of open RAN we were expecting to go live in 2022 (shown in the chart below), only three had done so by the time of writing.
  • Two of these were on the same network: Altiostar and Mavenir RAN platforms at DISH. The other was a converged Parallel Wireless 2G / 3G RAN deployment for Orange Central African Republic.
  • This is hardly the wave of 5G open RAN, macro-network roll-outs that the likes of Deutsche Telekom, Orange, Telefónica and Vodafone originally committed to for 2022. What has gone wrong?
  • Open RAN has come up against a number of thorny technological and operational challenges, which are well known to open RAN watchers:
    • integration challenges and costs
    • hardware performance and optimisation
    • immature ecosystem and unclear lines of accountability when things go wrong
    • unproven at scale, and absence of economies of scale
    • energy efficiency shortcomings
    • need to transform the operating model and processes
    • pressured 5G deployment and Huawei replacement timelines
    • absence of mature, open, horizontal telco cloud platforms supporting CNFs.
  • Over and above these factors, open RAN is arguably not essential for most of the 5G use cases it was expected to support.
  • This can be gauged by looking at some of the many open RAN trials that have not yet resulted in commercial deployments.

Beating the crash: What’s coming?

Signs of tougher times

Tough times are ahead…

As we look ahead, the world faces a number of significant challenges:

  • Global / OECD consumer confidence is diving to startling new depths as people increasingly feel the impact of inflation, supply constraints and a cost of living crisis.
  • This follows the war in Ukraine, the Covid pandemic and long Covid, stresses resulting from diverging political ideologies, growing social unrest, and the ever increasing realisation of the impact of climate change.
  • These seismic tensions are all driven by nearly 8 billion (and growing) people vying for resources and a vision of the future that they can continue to thrive in.

…but it’s not our first rodeo…

We have previously written about, for example:

And before that, there was the Credit Crunch series (2008), the Eurozone Crisis (2012), and technology and market disruptions too numerous to name.

There is always a temptation to think that the latest crisis is the worst. Each one tends to temporarily obliterate one’s view of the future as our imaginations are so absorbed in dealing with the nearby threat that all other considerations become secondary.

…and we believe we can bring some hope

Our solution to these challenges is two-fold. First, there is a lot that can be learned by looking at the lessons from previous traumas. Secondly, it is extremely helpful to be able to position all the individual events within an overall context, as it enables us to more rapidly reorientate after the latest shock.

Our context is The Coordination Age – the vision that the world is entering into a new era where:

  • The primary need is to make better use of available resources (e.g. money, carbon, time, assets, etc)
  • And that connecting technologies (e.g. telecommunications, data, automation and AI) are key elements of the solution.

Making the Coordination Age work

This report uses these learnings to look ahead to what we see as a challenging time. While some of the forces we outline in this report may seem alarming, this is not a pessimistic picture. We believe that the vision we describe brings opportunities for telecoms – but only if leaders in telecoms and elsewhere act on the vision. We are striving to make this happen, and we hope we can help you do that too.

A scale of discovery

To help contextualise the many forces of change, we have developed a six-stage schematic to generalise how people deal with new forces and changes in their lives. It progresses from the first recognition of a new theme or issue through to normalisation, the point where something is no longer new or different. The graphic below highlights the six stages, and general heuristic descriptions of what you might hear said, risks and threats, mitigations, and the general psychological and emotional mindset of those processing the change or issue in question.

Six stages of dealing with new ideas

The body of the report covers the drivers, their impact and consequences for telecoms:

  • Economic drivers, such as consumer confidence, inflation, and rising living costs
  • Environmental drivers, including climate change and carbon reduction
  • Political drivers, including the War in Ukraine, China / US tensions, trade wars and tensions
  • Social drivers, including Covid and Long Covid, inequalities and social polarisation.

Economic drivers: A crisis of confidence

In this section we examine drivers in consumer confidence, inflation / cost-of-living concerns and the consequences for telecoms.

Consumer confidence: An all-time low

The OECD consumer confidence index is a barometer of consumer sentiment. It reflects people’s confidence in their economic prospects. The chart below shows that it is currently reaching record new lows.

The OECD Consumer confidence index is at its lowest ever level

OECD-consumer-inflation-index-june-2022

Source: OECD

This means that consumers feel extremely pessimistic about their economic prospects. The average score is now below where it was at the peak of anxiety about Covid in early 2020, and below where it was in the financial crash in 2008-09. Indeed, the OECD average is now at its lowest ever level since global measures were introduced in the early 1970s, with only Mexico and Indonesia bucking the downward trend.

People are now preparing for a tough period in their economies. Some are worried about making ends meet – having enough to live to the standard they normally expect. This usually means that they will look to cut back on spending, especially for non-essential things.

Inflation is worrying everyone in Summer 2023

The pressures behind this trend are a generalised concern about inflation (rising prices on essential items like food) leading to a cost-of-living crisis.

Inflation overtook other global concerns in April 2022

Telco Cloud Deployment Tracker: 5G core deep dive

Deep dive: 5G core deployments 

In this July 2022 update to STL Partners’ Telco Cloud Deployment Tracker, we present granular information on 5G core launches. They fall into three categories:

  • 5G Non-standalone core (5G NSA core) deployments: The 5G NSA core (agreed as part of 3GPP Release in December 2017), involves using a virtualised and upgraded version of the existing 4G core (or EPC) to support 5G New Radio (NR) wireless transmission in tandem with existing LTE services. This was the first form of 5G to be launched and still accounts for 75% of all 5G core network deployments in our Tracker.
  • 5G Standalone core (5G SA core) deployments: The SA core is a completely new and 5G-only core. It has a simplified, cloud-native and distributed architecture, and is designed to support services and functions such as network slicing, Ultra-Reliable Low-Latency Communications (URLLC) and enhanced Machine-Type Communications (eMTC, i.e. massive IoT). Our Tracker indicates that the upcoming wave of 5G core deployments in 2022 and 2023 will be mostly 5G SA core.
  • Converged 5G NSA/SA core deployments: this is when a dual-mode NSA and SA platform is deployed; in most cases, the NSA core results from the upgrade of an existing LTE core (EPC) to support 5G signalling and radio. The principle behind a converged NSA/SA core is the ability to orchestrate different combinations of containerised network functions, and automatically and dynamically flip over from an NSA to an SA configuration, in tandem – for example – with other features and services such as Dynamic Spectrum Sharing and the needs of different network slices. For this reason, launching a converged NSA/SA platform is a marker of a more cloud-native approach in comparison with a simple 5G NSA launch. Ericsson is the most commonly found vendor for this type of platform with a handful coming from Huawei, Samsung and WorkingGroupTwo. Albeit interesting, converged 5G NSA/SA core deployments remain a minority (7% of all 5G core deployments over the 2018-2023 period) and most of our commentary will therefore focus on 5G NSA and 5G SA core launches.

  • There is renewed activity this year in 5G core launches since the total number of 5G core deployments so far in 2022 (effective and in progress) stands at 49, above the 47 logged in the whole of 2021. At the very least, total 5G deployments in 2022 will settle between the level of 2021 and the peak of 2020 (97).
  • 5G in whichever form now exists in most places where it was both in demand and affordable; but there remain large economies where it is yet to be launched: Turkey, Russia and most notably India. It also remains to be launched in most of Africa.
  • In countries with 5G, the next phase of launches, which will see the migration of NSA to SA cores, has yet to take place on a significant scale.
  • To date, 75% of all 5G cores are NSA. However, 5G SA will outstrip NSA in terms of deployments in 2022 and represent 24 of the 49 launches this year, or 34 if one includes converged NSA/SA cores as part of the total.
  • All but one of the 5G launches announced for 2023 are standalone; they all involve Tier-1 MNOs including Orange (in its European footprint involving Ericsson and Nokia), NTT Docomo in Japan and Verizon in the US.

The upcoming wave of SA core (and open / vRAN) represents an evolution towards cloud-native

  • Cloud-native functions or CNFs are software designed from the ground up for deployment and operation in the cloud with:​
  • Portability across any hardware infrastructure or virtualisation platform​
  • Modularity and openness, with components from multiple vendors able to be flexibly swapped in and out based on a shared set of compute and OS resources, and open APIs (in particular, via software ‘containers’)​
  • Automated orchestration and lifecycle management, with individual micro-services (software sub-components) able to be independently modified / upgraded, and automatically re-orchestrated and service-chained based on a persistent, API-based, ‘declarative’ framework (one which states the desired outcome, with the service chain organising itself to deliver the outcome in the most efficient way)​
  • Compute, resource, and software efficiency: as a concomitant of the automated, lean and logically optimal characteristics described above, CNFs are more efficient (both functionally and in terms of operating costs) and consume fewer compute and energy resources.​
  • Scalability and flexibility, as individual functions (for example, distributed user plane functions in 5G networks) can be scaled up or down instantly and dynamically in response to overall traffic flows or the needs of individual services​
  • Programmability, as network functions are now entirely based on software components that can be programmed and combined in a highly flexible manner in accordance with the needs of individual services and use contexts, via open APIs.​

Telco cloud: short-term pain, long-term gain

Telcos have invested in telco cloud for several years: Where’s the RoI?

Over a number of years – starting in around 2014, and gathering pace from 2016 onwards – telcos have invested a large amount of money and effort on the development and deployment of their ‘telco cloud’ infrastructure, virtualised network functions (VNFs), and associated operations: long enough to expect to see measurable returns. As we set out later in this report, operators initially hoped that virtualisation would make their networks cheaper to run, or at least that it would prevent the cost of scaling up their networks to meet surging demand from spiralling out of control. The assumption was that buying commercial off-the-shelf (COTS) hardware and running network functions as software over it would work out less costly than buying proprietary network appliances from the vendors. Therefore, all things being equal, virtualisation should have translated into lower opex and capex.

However, when scrutinising operators’ reported financials over the past six years, it is impossible to determine whether this has been the case or not:

  • First, the goalposts are constantly shifting in the telecoms world, especially in recent years when massive 5G and fibre roll-outs have translated into substantial capex increases for many operators. But this does not mean that what they buy is more (or less) expensive per unit, just that they need more of it.
  • Most virtualisation effort has gone into core networks, which do not represent a large proportion of an operator’s cost base. In fact, overall expenditure on the core is dwarfed by what needs to be spent on the fixed and mobile access networks. As a ballpark estimate, for example, the Radio Access Network (RAN) represents 60% of mobile network capex.
  • Finally, most large telco groups are integrated operators that report capex or opex (or both) for their fixed and mobile units as a whole; this makes it even more difficult to identify any cost savings related to mobile core or any other virtualisation.

For this reason, when STL Partners set out to assess the economic benefit of virtualisation in the first half of 2022, it quickly became apparent that the only way to do this would be through talking directly to telcos’ CTOs and principal network engineers, and to those selling virtualisation solutions to them. Accordingly, STL Partners carried out an intensive interview programme among leading operators and vendors to find out how they quantify the benefits, financial or otherwise, from telco cloud.

What emerged was a complex and nuanced picture: while telcos struggle to demonstrate RoI from their network cloudification activities to date, many other benefits have accrued, and telcos are growing in their conviction that further cloudification is essential to meet the business, innovation and technology challenges that lie ahead – many of which cannot (yet) be quantified.

The people we spoke to comprised senior, programme-leading engineers, executives and strategists from eight operators and five vendors.

The operators concerned included: four Tier-1 players, three Tier-2 and one Tier-3. These telcos were also evenly split across the three deployment pathways explained below: two Pathway 1 (single-vendor/full-stack); three Pathway 2 (vendor-supported best-of-breed); and three Pathway 3 (DIY best-of-breed).

Four of the vendors interviewed were leading global providers of telco cloud platforms, infrastructure and integration services, and one was a challenger vendor focused on the 5G Standalone (SA) core. The figure below represents the geographical distribution of our interviewees, both telcos and vendors. Although we lacked interviewees from the APAC region and did not gain access to any Chinese operators, we were able to gain some regional insight through interviewing a new entrant in one of the major Asian markets.

Virtualisation will go through three phases, corresponding to three deployment pathways

This process of telco cloudification has already gone through two phases and is entering a third phase, as illustrated below and as decribed in our Telco Cloud Manifesto, published in March 2021:

Phases of telco cloudification

Source: STL Partners

Effectively, each of these phases represents an approximately three to five-year investment cycle. Telcos have begun these investments at different times: Tier-1 telcos are generally now in the midst of their Phase 2 investments. By contrast, Tier-2s and -3s, smaller MNOs, and Tier-1s in developing markets are generally still going through their initial, Phase 1 investments in virtualisation.

Given that the leading Tier-1 players are now well into their second virtualisation investment cycle, it seems reasonable to expect that they would be able to demonstrate a return on investment from the first phase. This is particularly apt in that telcos entered into the first phase – Network Functions Virtualisation (NFV) – with the specific goal of achieving quantifiable financial and operational benefits, such as:

  • Reduction in operational and capital expenditures (opex and capex), resulting from the ability to deliver and run NFs from software running on COTS hardware (cheaper per unit, but also more likely to attract economies of scale), rather than from expensive, dedicated equipment requiring ongoing, vendor-provided support, maintenance and upgrades
  • Greater scalability and resource efficiency, resulting from the ability to dynamically increase or decrease the capacity of network-function Virtual Machines (VMs), or to create new instances of them to meet fluctuating network capacity and throughput requirements, rather than having to purchase and maintain over-specified, redundant physical appliances and facilities to guarantee the same sort of capacity and resilience
  • Generation of new revenue streams, resulting from the ability that the software-centricity of virtualised networks provides to rapidly innovate and activate services that more closely address customer needs.

Problem: With a few exceptions, telcos cannot demonstrate RoI from virtualisation

Some of the leading telco advocates of virtualisation have claimed variously to have achieved capex and/or opex reductions, and increases in top-line revenues, thanks to their telco cloud investments. For example, in January 2022, it was reported that some technical modelling had vindicated the cost-reduction claims of Japanese greenfield, ‘cloud-native’ operator Rakuten Mobile: it showed that Rakuten’s capex per cell site was around 40% lower, and its opex 30% lower, than the MNO incumbents in the same market. Some of the savings derived from automation gains related to virtualisation, allowing cell sites to be activated and run remotely on practically a ‘plug and play’ basis.

Similarly, Vodafone claimed in 2020 that it had reduced the cost of its mobile cores by 50% by running them as VNFs on the VMware telco cloud platform.

The problem is that the few telcos that are willing to quantify the success of their virtualisation programmes in this way are those that have championed telco cloud most vocally. And these telcos have also gone further and deeper with cloudification than the greater mass of the industry, and are now pushing on with Phase 3 virtualisation: full cloud-native. This means that they are under a greater pressure to lay claim to positive RoI and are able to muster data points of different types that appear to demonstrate real benefits, without being explicit about the baseline underpinning their claims: what their costs and revenues would, or might, have been had they persisted with the old physical appliance-centric model.

But this is an unreal comparison. Virtualisation has arisen because telco networks need to do more, and different things, than the old appliance-dependent networks enabled them to do. In the colourful expression of one of the industry experts we interviewed as part of our research, this is like comparing a horse to a computer.

In the first part of this report, we discuss the reasons why telcos generally cannot unequivocally demonstrate RoI from their telco cloud investments to date. In the second part, we discuss the range of benefits, actual and prospective, that telcos and vendors have observed from network cloudification, broken down by the three main pathways that telcos are following, as referred to above.

Telco Cloud Deployment Tracker: Open RAN deep dive

Telco Cloud: Open RAN is a work in progress

This report accompanies the latest release and quarterly update of STL Partners ‘Telco Cloud Deployment Tracker’ database. This contains data on deployments of VNFs (Virtual Network Functions), CNFs (cloud-native network functions) and SDN (Software Defined Networking) in the networks of the leading telcos worldwide. In this update we have added some additional categories to the database to reflect the different types of virtualised / open RAN:

  1. Open RAN / O-RAN: Fully open, disaggregated, virtualised / cloud-native, with CU / DU split
  2. vRAN: Virtualised CU/DU, with open interfaces but implemented as an integrated, single-vendor platform
  3. Cloud RAN: Single-vendor, virtualised / centralised BU, or CU only, with proprietary / closed interfaces

Cloud RAN is the most limited form of virtualised RAN: It is based on porting part or all of the functionality of the legacy, appliance-based BU into a Virtual Machine. vRAN and open RAN are much more significant, in both technology and business-model terms, breaking open all parts of the RAN to more competition and opportunities for innovation.

Accordingly, the report presents data on only open RAN and vRAN deployments however a granular analysis of each category of RAN deployment can be carried out using the Telco Cloud Tracker tool.

Open RAN and vRAN deployments, 2018 – 2022

Open-RAN-Deployments-Apr-2021-STL-Partners

Open RAN and vRAN

Both Open RAN and vRAN are virtualised (with the exception of NTT DoCoMo as outlined in the report), but ‘open RAN’ implies full disaggregation of the different parts of the RAN (hardware, software and radio), and open interfaces between them. By contrast, vRAN incorporates the open interfaces but is generally deployed as a pre-integrated, single-vendor solution: hardware, software and radio supplied by the same vendor.

To date, there have been significantly more open RAN than vRAN deployments. But vRAN is emerging as a potentially competitive alternative to pure open RAN: offering the same operational benefits and – in theory – multi-vendor openness, but without the overhead of integrating components from multiple vendors, and a ‘single neck to choke’ if things go wrong. Deployments in 2020 were mostly small-scale and / or 4G, including trials which continued to carry live traffic after the trial period came to an end.

The stark contrast between 2021 and 2022 reflects a slight hiatus in commercial deployments as work intensified around integration and operational models, trials, performance optimisation, and cost economics. However, major deployments are expected in 2022, including greenfield networks 1&1 Drillisch (Germany) and DISH (US), Verizon, Vodafone UK, and MTN (Africa and ME).

Scope and content of the Tracker

The data in the latest update of our interactive tool and database covers the period up to March 2022, although reference is made in the report to events and deployments after that date. The data is drawn predominantly from public-domain information contained in news releases from operators and vendors, along with reputable industry media.

We apply the term ‘deployment’ to refer to the total set of VNFs, CNFs or SDN technology, and their associated management software and infrastructure, deployed at an operator – or at one or more of an operator’s opcos or natcos – in order to achieve a defined objective or support particular services (in the spreadsheet, we designate these as the ‘primary purpose’ of the deployment). For example, this could be:

  • to deploy a 5G standalone core
  • to launch a software-defined WAN (SD-WAN) service
  • or to construct a ‘telco cloud’ or NFV infrastructure (NFVi): a cloud infrastructure platform on which virtualised network services can be introduced and operated.

The Tracker is provided as an interactive tool containing line-by-line analysis of over 900 individual deployments of VNFs, CNFs or SDN technology, which can be used to drill down by:

  • Region where deployed
  • Operator
  • Technology vendor
  • Primary purpose
  • Type of telco cloud function deployed
  • …and more filters

VNFs on public cloud: Opportunity, not threat

VNF deployments on the hyperscale cloud are just beginning

Numerous collaboration agreements between hyperscalers and leading telcos, but few live VNF deployments to date

The past three years have seen many major telcos concluding collaboration agreements with the leading hyperscalers. These have involved one or more of five business models for the telco-hyperscaler relationship that we discussed in a previous report, and which are illustrated below:

In this report, we focus more narrowly on the deployment, delivery and operation by and to telcos of virtualised and cloud-native network functions (VNFs / CNFs) over the hyperscale public cloud. To date, there have been few instances of telcos delivering live, commercial services on the public network via VNFs hosted on the public cloud. STL Partners’ Telco Cloud Deployment Tracker contains eight examples of this, as illustrated below:

Telcos are looking to generate returns from their telco cloud investments and maintain control over their ‘core business’

The telcos in the above table are all of comparable stature and ambition to the likes of AT&T and DISH in the realm of telco cloud but have a diametrically opposite stance when it comes to VNF deployment on public cloud. They have decided against large-scale public cloud deployments for a variety of reasons, including:

  • They have invested a considerable amount of money, time and human resources on their private clouddeployments, and they want and need to utilise the asset and generate the RoI.
  • Related to this, they have generated a large amount of intellectual property (IP) as a result of their DIY cloud– and VNF-development work. Clearly, they wish to realise the business benefits they sought to achieve through these efforts, such as cost and resource efficiencies, automation gains, enhanced flexibility and agility, and opportunities for both connectivityand edge compute service innovation. Apart from the opportunity cost of not realising these gains, it is demoralising for some CTO departments to contemplate surrendering the fruit of this effort in favour of a hyperscaler’s comparable cloud infrastructure, orchestration and management tools.
  • In addition, telcos have an opportunity to monetise that IP by marketing it to other telcos. The Rakuten Communications Platform (RCP) marketed by Rakuten Symphony is an example of this: effectively, a telco providing a telco cloud platform on an NFaaS basis to third-party operators or enterprises – in competition to similar offerings that might be developed by hyperscalers. Accordingly, RCP will be hosted over private cloud facilities, not public cloud. But in theory, there is no reason why RCP could not in future be delivered over public cloud. In this case, Rakuten would be acting like any other vendor adapting its solutions to the hyperscale cloud.
  • In theory also, telcos could also offer their private telcoclouds as a platform, or wholesale or on-demand service, for third parties to source and run their own network functions (i.e. these would be hosted on the wholesale provider’s facilities, in contrast to the RCP, which is hosted on the client telco’s facilities). This would be a logical fit for telcos such as BT or Deutsche Telekom, which still operate as their respective countries’ communications backbone provider and primary wholesale provider

BT and Deutsche Telekom have also been among the telcos that have been most visibly hostile to the idea of running NFs powering their own public, mass-market services on the public and hyperscale cloud. And for most operators, this is the main concern making them cautious about deploying VNFs on the public cloud, let alone sourcing them from the cloud on an NFaaS basis: that this would be making the ‘core’ telco business and asset – the network – dependent on the technology roadmaps, operational competence and business priorities of the hyperscalers.

5G standalone (SA) will hit an inflection point in 2022

5G standalone (SA) core is beginning to take off, with 19 deployments so far expected to be completed in 2022. The eventual total will be higher still, as will that of NSA core, as NSA 5G networks continue to be launched. As non-standalone (NSA) cores are replaced by SA, this will result in another massive wave of core deployments – probably from 2023/4 onwards.

Why and how to go telco cloud native: AT&T, DISH and Rakuten

The telco business is being disaggregated

Telcos are facing a situation in which the elements that have traditionally made up and produced their core business are being ‘disaggregated’: broken up into their component parts and recombined in different ways, while some of the elements of the telco business are increasingly being provided by players from other industry verticals.

By the same token, telcos face the pressure – and the opportunity – to combine connectivity with other capabilities as part of new vertical-specific offerings.

Telco disaggregation primarily affects three interrelated aspects of the telco business:

  1. Technology:
    • ‘Vertical’ disaggregation: separating out of network functions previously delivered by dedicated, physical equipment into software running on commodity computing hardware (NFV, virtualisation)
    • ‘Horizontal’ disaggregation: breaking up of network functions themselves into their component parts – at both the software and hardware levels; and re-engineering, recombining and redistributing of those component parts (geographically and architecturally) to meet the needs of new use cases. In respect of software, this typically involves cloud-native network functions (CNFs) and containerisation
    • Open RAN is an example of both types of disaggregation: vertical disaggregation through separation of baseband processing software and hardware; and horizontal disaggregation by breaking out the baseband function into centralised and distributed units (CU and DU), along with a separate, programmable controller (RAN Intelligent Controller, or RIC), where all of these can in theory be provided by different vendors, and interface with radios that can also be provided by third-party vendors.
  2. Organisational structure and operating model: Breaking up of organisational hierarchies, departmental siloes, and waterfall development processes focused on the core connectivity business. As telcos face the need to develop new vertical- and client-specific services and use cases beyond the increasingly commoditised, low-margin connectivity business, these structures are being – or need to be – replaced by more multi-disciplinary teams taking end-to-end responsibility for product development and operations (e.g. DevOps), go-to-market, profitability, and technology.

Transformation from the vertical telco to the disaggregated telco

3. Value chain and business model: Breaking up of the traditional model whereby telcos owned – or at least had end-to-end operational oversight over – . This is not to deny that telcos have always relied on third party-owned or outsourced infrastructure and services, such as wholesale networks, interconnect services or vendor outsourcing. However, these discrete elements have always been welded into an end-to-end, network-based services offering under the auspices of the telco’s BSS and OSS. These ensured that the telco took overall responsibility for end-to-end service design, delivery, assurance and billing.

    • The theory behind this traditional model is that all the customer’s connectivity needs should be met by leveraging the end-to-end telco network / service offering. In practice, the end-to-end characteristics have not always been fully controlled or owned by the service provider.
    • In the new, further disaggregated value chain, different parts of the now more software-, IT- and cloud-based technology stack are increasingly provided by other types of player, including from other industry verticals. Telcos must compete to play within these new markets, and have no automatic right to deliver even just the connectivity elements.

All of these aspects of disaggregation can be seen as manifestations of a fundamental shift where telecoms is evolving from a utility communications and connectivity business to a component of distributed computing. The core business of telecoms is becoming the processing and delivery of distributed computing workloads, and the enablement of ubiquitous computing.

Telco disaggregation is a by-product of computerisation

Telco industry disaggregation is part of a broader evolution in the domains of technology, business, the economy, and society. This evolution comprises ‘computerisation’. Computing analyses and breaks up material processes and systems into a set of logical and functional sub-components, enabling processes and products to be re-engineered, optimised, recombined in different ways, managed, and executed more efficiently and automatically.

In essence, ‘telco disaggregation’ is a term that describes a moment in time at which telecoms technology, organisations, value chains and processes are being broken up into their component parts and re-engineered, under the impact of computerisation and its synonyms: digitisation, softwarisation, virtualisation and cloud.

This is part of a new wave of societal computerisation / digitisation, which at STL Partners we call the Coordination Age. At a high level, this can be described as ‘cross-domain computerisation’: separating out processes, services and functions from multiple areas of technology, the economy and society – and optimising, recombining and automating them (i.e. coordinating them), so that they can better deliver on social, economic and environmental needs and goals. In other words, this enables scarce resources to be used more efficiently and sustainably in pursuit of individual and social needs.

NFV has computerised the network; telco cloud native subordinates it to computing

In respect of the telecoms industry in particular, one could argue that the first wave of virtualisation (NFV and SDN), which unfolded during the 2010s, represented the computerisation and digitisation of telecoms networking. The focus of this was internal to the telecoms industry in the first instance, rather than connected to other social and technology domains and goals. It was about taking legacy, physical networking processes and functions, and redesigning and reimplementing them in software.

Then, the second wave of virtualisation (cloud-native – which is happening now) is what enables telecoms networking to play a part in the second wave of societal computerisation more broadly (the Coordination Age). This is because the different layers and elements of telecoms networks (services, network functions and infrastructure) are redefined, instantiated in software, broken up into their component parts, redistributed (logically and physically), and reassembled as a function of an increasing variety of cross-domain and cross-vertical use cases that are enabled and delivered, ultimately, by computerisation. Telecoms is disaggregated by, subordinated to, and defined and controlled by computing.

In summary, we can say that telecoms networks and operations are going through disaggregation now because this forms part of a broader societal transformation in which physical processes, functions and systems are being brought under the control of computing / IT, in pursuit of broader human, societal, economic and environmental goals.

In practice, this also means that telcos are facing increasing competition from many new types of actor, such as:

  • Computing, IT and cloud players
  • More specialist and agile networking providers
  • And vertical-market actors – delivering connectivity in support of vertical-specific, Coordination Age use cases.

O-RAN: What is it worth?

Introducing STL Partners’ O-RAN Market Forecast

This capex forecast is STL Partners’ first attempt at estimating the value of the O-RAN market.

  • This is STL Partners’ first O-RAN market value forecast
  • It is based on analysis of telco RAN capex and projected investment pathways for O-RAN
  • The assumptions are informed by public announcements, private discussions and the opinions of our Telco Cloud team
  • We look forward to developing it further based on client feedback

Enter your details below to request an extract of the report

What is O-RAN?

We define O-RAN as virtualised, disaggregated, open-interface architectures.

  • Our O-RAN capex forecasts cover virtualised, disaggregated, open-interface architectures in the Radio Access Network
  • They do not include vRAN or O-RAN compliant but single vendor deployments

O-RAN definition open RAN

O-RAN will account for 76% of active RAN capex by 2030

As mobile operators upgrade their 4G networks and invest in new 5G infrastructure, they can continue purchasing single vendor legacy RAN equipment or opt for multi-vendor open-standard O-RAN solutions.

Each telco will determine its O-RAN roadmap based on its specific circumstances (footprint, network evolution, rural coverage, regulatory pressure, etc)1. For the purpose of this top-level O-RAN capex forecast, STL has defined four broad pathways for transitioning from legacy RAN/vRAN to O-RAN and categorised each of the top 40 mobile operators in one of the pathways, based on their announced or suspected O-RAN strategy.

Through telcos’ projected mobile capex and the pathway categorisation, we estimate that by 2026 annual sales of O-RAN active network elements (including equipment and software) will reach USD12 billion, or 21% of all active RAN capex (excluding passive infrastructure). By 2030, these will reach USD43 billion and 76%, respectively.

2020 in review and focus on North America: How should telcos do cloud?

Tenth update of the Telco Cloud Tracker

This report accompanies the tenth release of STL Partners’ ‘Telco Cloud Tracker’ database. This contains data on deployments of NFV (Network Functions Virtualisation), SDN (Software Defined Networking) and cloud-native network functions (CNFs) in the networks of the leading telcos worldwide. This analytical report focuses on trends in North America, set in global context.

Scope and content of the Tracker

The data in the tenth update covers the period up to the end of January 2021, although reference is made in the report to events and deployments after that date. The data is drawn predominantly from public-domain information contained in news releases from operators and vendors, along with reputable industry media. However, it also includes a smaller set of deployment data disclosed to us confidentially by operators and vendors. This information is added to the aggregate data sections of the ‘Tracker’ spreadsheet, which do not refer to the specific solutions supplied or the operators where they were deployed.

We apply the term ‘deployment’ to refer to the total set of virtual network functions (VNFs), CNFs or SDN technology, and their associated management software and infrastructure, deployed at an operator – or at one or more of an operator’s opcos or natcos – in order to achieve a defined objective or support particular services (in the spreadsheet, we designate these as the ‘primary purpose’ of the deployment). For example, this could be:

  • to implement a virtualised mobile core
  • to launch a software-defined WAN (SD-WAN) service
  • or to construct a ‘telco cloud’ or NFV infrastructure (NFVi): a cloud infrastructure platform on which virtualised network services can be introduced and operated.

Accordingly, some of the deployments contained in the database comprise multiple elements, which are listed separately, including details about the category of NFV / SDN / CNF, and vendor and product name where known.

In addition to these mainly public-domain deployments, there are many non-publicised deployments that are inevitably omitted from the ‘Tracker’. However, the ever-growing ‘Tracker’ database now constitutes a considerable body of research that in our view offers a reliable snapshot of the overall market and the main trends in the evolution of telco cloud. In addition, as the ‘Tracker’ contains details only of deployments in live, commercial telco networks (either completed or in progress), this provides a useful corrective to the hype of some vendors’ pronouncements about agreements with operators, which often relate only to collaboration arrangements and preliminary trials, rather than commercial roll-outs.

The one exception to this rule of including only deployments that are implemented to support commercial services is a limited set of data on some of the current live network trials of open and / or virtual RAN (vRAN). The reason for making this exception is the very high level of interest currently in open RAN.

In terms of the telcos included, we limit the database mainly to Tier-One international and national telecoms operators, along with national fixed and mobile operators in smaller markets. For subsequent updates, we may expand the range and types of service providers included, because telco cloud is opening up opportunities for new players to provide cloud- and CNF-based connectivity and related services that are competing strongly with classic telco services.

SD-WAN in focus

In this update of the Tracker we have included a deep dive on SD-WAN, which was one of the main early drivers of SDN/NFV deployments, particularly among North American operators. It is worth exploring in more detail because, as it evolves into an increasingly cloud-centric and cloud-native service, it is emerging as another battleground between operators, hyperscalers and vendors.

5G is driving deployments – but will it drive business model change?

This is the first update to the ‘Telco Cloud Tracker’ in 2021, which provides an opportunity to review 2020 and discuss the key trends in 2021.

Despite the global pandemic, the pace of virtualised network function (VNF) deployments has continued at a strong level.

Total deployments by region, 2016 to 2021

Our projection is that the final number of deployments in 2020 will be at around the same level as 2019 (182 in total). Many live deployments are confirmed some time after the event, swelling the totals for previous years. Accordingly, some of the deployments currently recorded as ‘in progress’ will be added to the tally for 2020.

5G core dominates the scene but is done largely via single-vendor, ‘vertical’ NFV

The main driver of deployments in 2020 was 5G network launches around the world, particularly in the second half of the year. This meant that many Non-standalone (NSA) 5G cores – the platform supporting almost all live 5G networks – also went live, as is illustrated below:

 Deployments by leading network function, 2016 to 2021

We recorded 76 completed deployments of NSA cores in 2020, up from 56 in 2019. A further ten deployments were either completed or pending in the first quarter of 2021.

The Telco Cloud Manifesto

Telco cloud: A key enabler of the Coordination Age

The Coordination Age is coming

As we have set out in our company manifesto, STL Partners believes that we are entering a new ‘Coordination Age’ in which technological developments will enable governments, enterprises, and consumers to coordinate their activities more effectively than ever before. The results of better and faster coordination will be game-changing for society as resources are distributed and used more effectively than ever before leading to substantial social, economic, and health benefits.

A critical component of the Coordination Age is the universal availability of flexible, fast, reliable, low-latency networks that support a myriad of applications which, in turn, enable a complex array of communications, decisions, transactions, and processes to be completed quickly and, in many cases, automatically without human intervention.  The network remains key: without it being fit for purpose the ability to match demand and supply real-time is impossible.

How telecoms can define a new role

Historically, telecoms networks have been created using specialist dedicated (proprietary) hardware and software.  This has ensured networks are reliable and secure but has also stymied innovation – from operators and from third-parties – that have found leveraging network capabilities challenging.  In fact, innovation accelerated with the arrival of the Internet which enabled services to be decoupled from the network and run ‘over the top’.

But the Coordination Age requires more from the network than ever before – applications require the network to be flexible, accessible and support a range of technical and commercial options. Applications cannot run independently of the network but need to integrate with it. The network must be able to impart actionable insights and flex its speed, bandwidth, latency, security, business model and countless other variables quickly and autonomously to meet the needs of applications using it.

Telco cloud – the move to a network built on common off-the-shelf hardware and flexible interoperable software from best-of-breed suppliers that runs wherever it is needed – is the enabler of this future.

Telecoms priorities: Ready for the crunch?

The goal of this research is to understand how telecoms operators’ investment priorities and investments are likely to change as the COVID-19 crisis recedes.  To do this, we collected 144 survey responses from participants in telecoms operators, telecoms vendors, and analysts and consultants and other groups. All responses are treated in strict personal and company confidence. Take the survey here.

This research builds on our previous content on the impact of the pandemic to the telecoms industry: COVID-19: Now, next and after (March 2020), COVID-19: Impact on telco priorities (May 2020), based on a survey undertaken in April and early May 2020 and Recovering from COVID: 5G to stimulate growth and drive productivity (August 2020).  STL Partners has also hosted three webinar on the topic (March to July 2020).

This deck summarises the findings of our industry research on telecoms priorities at the start of 2021.

We explored the research in our webinar,  State of the Industry: 2021 Priorities (click on the link to view the recording).

Background to the telecoms priorities survey – January 2021

The respondents were fairly evenly split between telcos, vendors, and ‘others’ (mainly analysts and consultants). This sample contained a higher proportion of European and American respondents than industry average, so is not fully globally representative. The split of company types and geography was broadly similar to the May 2020 survey, with the exception of the MENA region, where there were less than half the prior respondents – a total of 7. However those respondents were senior and well known to STL.

Who took the survey?

How respondents perceive priorities, as the COVID threat recedes

There were increases in respondent confidence in almost every category we surveyed from May 2020 to Jan 2021.

  • Telecoms automation and agility remain top priorities across the industry – and transformation has moved up the agenda.
  • Appetite for 5G investments increased the most of all areas surveyed in the last 8 months.
  • The ‘consumerisation’ of enterprise continues, although security and work from home (WFH) services have overtaken conferencing and VPNs in priority.
  • Healthcare remains the most accelerated vertical / application opportunity of all those impacted in the current crisis.
  • The priority of consumer services has significantly increased yet confidence in making any additional money in the sector is low.
  • Leadership and transformation: COVID 19 has empowered an industry-wide belief that change is possible.
  • Transformation and innovation are high priorities, and appetite for sustainability and recruitment has returned, but there are doubts about some telco leaders’ commitment and ability to grasp and invest in new opportunities.

STL Partners assesses the telecoms industry to be at a crunch point: COVID has injected further pace to the rapid evolution of the world economy. Telcos that have been focused on responding to immediate pandemic-induced challenges, will emerge from the crisis faced with an urgency to respond to this evolution – key choices that telcos might have had 5-10 years to ponder are being crunched into the next 0-3 years.

Our findings suggest that most telcos are only partly ready for this disruptive opportunity.

Notes on interpreting the research findings

  • The way research respondents perceive any given question is generally dependent on their current situation and knowledge. To get relevant answers, we asked all respondents if they were interested or involved in specific areas of interest (e.g. ‘consumer services’), and to not answer questions they couldn’t (e.g. for confidentiality reasons) or simply didn’t know or have a clear opinion.
  • We saw no evidence that respondents were ‘gaming’ the results to be favourable to their interests.
  • Results need to be seen in the context that telcos themselves vary widely in size, profitability and market outlook. For example, for some, 5G seems like a valid investment, whereas for others the conditions are currently much less promising. COVID-19 has clearly had some impact on these dynamics, and our analysis attempts to reflect this impact on the overall balance of opinions as well as some of the specific situations to bring greater nuance.
  • In December 2020 / January 2021, the worldwide impact of COVID-19 is increasingly well understood and less of a shock than was the case in May / June 2020. Vaccines are beginning to be rolled out but it is an early stage in the process, and new variants of COVID-19 have evolved in the UK, South Africa and Brazil (and possibly elsewhere). There are geo-political wrangles on vaccine distribution, and varying views on effectiveness and the most appropriate responses. Nonetheless, respondents appear overall more optimistic, although there is still considerable uncertainty.
  • We’ve interpreted the results as best we can given our knowledge of the respondents and what they told us, and added in our own insights where relevant.
  • Inevitably, this is a subjective exercise, albeit based on 144 industry respondents’ views.
  • Nonetheless, we hope that it brings you additional insights to the many that you already possess through your own experiences and access to data.
  • Finally, things continue to change fast. We will continue to track them.
