Transport and logistics: The role of private 4G/5G

A deep-dive into the transport and logistics sector

This report is a deep-dive into the transport and logistics vertical for private 4G/5G (P5G) cellular networks. It is intended to be both a specific examination of an important sector of opportunity for P5G and a more general example of the complexity of major industrial sectors, especially campus-based or larger-scale dedicated environments. It also covers opportunities for MNOs, and some of the public 5G angles, with additional references to alternative wireless networks such as Wi-Fi and satellite connectivity.

Often technology product and marketing executives think of industry sectors as monolithic (“finance”, “retail”, “oil and gas”, etc.), typically aligning with familiar industry classification codes. The truth is that each industry has multiple sub-sectors and varied site types, numerous applications, several user-groups, arrays of legacy systems and technology vendors, and differing attitudes and affordability of wireless solutions. This is especially true of transport and logistics, where railway stations share only limited technology or use case overlap with airports, or distribution warehouses.

The transport sector is further complicated by its overlap with the public sector – not only does it constitute an important part of countries’ critical national infrastructure, but in many cases major transport firms have a history of state ownership, or are still owned and run by governments today.

There are also numerous sector-specific regulatory angles, which often translate to conservatism about technology, and a tendency to develop custom solutions and standards. Investment cycles can be very long and sometimes politicised, with assets often expected to be in place for decades. On the positive side, the strategic importance of transport can mean that the sector receives special attention in areas such as spectrum allocations.

Definition of the transport and logistics sector

There are numerous transport and logistics sub-sectors and site types covered in this report. Although there are some common features and market drivers, there are also clear differences in locations’ physical size and layout, as well as equipment and application platforms, legacy/alternative wireless technologies, regulatory oversight and technology conservatism.

Multiple sub-sectors for transport / logistics vertical

The key domains covered include:

  • Transportation hubs, which refers to sites like ports, airports, stations and railyards. They vary significantly in size.
  • Logistics, which relates to the centralised facilities for shipping, storage and sorting of containers and packages, such as warehouses and fulfilment / distribution centres. It also encompasses the wide-area / global transport of containers, packages and bulk products on trucks, trains and ships.
  • Transport networks including rail networks, metropolitan transit and light-rail systems, and road networks.

There are also often hybrid sites, such as FedEx’s huge logistics hub sites next to Memphis and Indianapolis airports.

In addition, there is also significant overlap with various other sectors, such as major manufacturing sites. For instance, aerospace manufacture and maintenance typically occurs at combined factories/airfields such as Boeing and Airbus’ facilities. Similar combined operations occur in ship-building and train production. Mining, steel and cement companies may even have their own private rail-lines, from remote sites or industrial zones, to multi-modal transit hubs at ports or cities.

For logistics sites, it should be noted that many facility owners also have large retail networks (such as Costco and Walmart), or other sites such as Amazon’s AWS datacentres. Those ancillary operations and their specific applications are not directly included here.

For metropolitan transit, various transport-related facilities may be under the ownership or control of local government and municipal bodies. Similar overlaps between transport-related sites and government occur for military, public safety and other agencies.

Transport / logistics intersects with several adjacent verticals

Sector trends and drivers affecting private networks

This report is not the appropriate venue for a full analysis of the transport and logistics industry, which is made up of multiple sub-sectors, as discussed above.

However, the demand for private networks for these sectors is ultimately driven by a number of top-level national and global changes, in addition to certain local factors such as political support for new metro transit systems, “free ports” or enterprise zones, or efforts to modernise railway networks.

Broadly speaking, these all create a greater requirement for connectivity, control and information flows – which then translates to more 4G and 5G networks, as well as Wi-Fi, fibre and wide-area network services. There are also various new greenfield infrastructure projects, which lend themselves well to ground-up design of fit-for-purpose communications systems.

Some of the key megatrends spanning all aspects of logistics and transportation include:

  • Automation and robotics: As discussed throughout this report, transport hubs and warehouses are becoming much more automated. Although mechanisation via port cranes, baggage-handling systems and automated guided vehicles is not new, the systems are being enhanced rapidly. In particular, sorting or control systems, robots and other forms of automation are using wireless video cameras for detecting packages, enabling remote-control by tele-operators and many other uses.
  • Data and analytics: Transport and logistics companies are at the forefront of data-rich applications, from digital twins of jet engines and rail locomotives, to optimised scheduling and packaging of goods in fulfilment warehouses. Better-connected equipment, IoT sensors and video input can improve turnaround times, reduce shipment errors, reduce energy consumption and much more. Passenger-led transportation should face fewer delays, more dispersed crowds and improved customer service.
  • Predictive maintenance and asset management: Transport systems are capital-intensive. The cost of downtime for a vehicle – or critical system in a warehouse or airport terminal – can be huge. There is a huge opportunity for using networked information and sensors to enable predictive maintenance – i.e. fixing emergent problems before they become critical, or scheduling regular maintenance when it is needed rather than just based on a generic schedule. For instance, anomalous readings from vibration and temperature sensors can give early warnings of issues. There are also obvious safety benefits in areas such as aviation and maritime fault-diagnosis.
  • Improved employee safety and productivity: There is far less tolerance of industrial accidents than in the past. Using automation and better information, transportation and logistics firms are looking to increase worker productivity at the same time as improving safety. This spans many aspects, from ensuring safe distances between workers and vehicles, to rapid reaction to any incident, plus improved recordkeeping and training. Reliable communication is essential, using both voice (often push-to-talk) and an increasing need for video communications and mobile access to enterprise application.
  • Climate change and decarbonisation: Over the next decade, many transport and logistics businesses will face profound change as the planet heads towards net zero carbon emissions. Ports, airports, distribution centres and other sites are likely to need new electrical sources such as wind and solar, onsite battery storage, maybe hydrogen facilities and fleets of electric (often autonomous) site vehicles and machines. Connectivity will be needed for all of this, plus energy use monitoring, control, data-collection and reporting.
  • Geopolitics, re-shoring and supply-chain resilience: Recent events such as the US-China trade war, the COVID pandemic and the Russia/Ukraine war have highlighted the risks of global (and often fragile) supply chains to disruptive external events. Traffic and passenger levels at many airports fell to 20% of pre-pandemic levels or lower. While demand is now recovering in many places, other issues have emerged as well – from economic fluctuations, to fuel price inflation and staffing shortages. As well as localised production, shipping and logistics will need to be much more efficient, automated and connected in order to re-route shipments, store inventory and deal with new paperwork and compliance requirements.
  • Cybersecurity: Transport hubs and warehouses are part of national critical infrastructure. The rise of automation and cloud-based functions poses security challenges as well as gains from efficiency. Old IT, network and operational systems will be strengthened or retired if they have vulnerabilities, while networks will need extra resilience and redundancy. Wireless networks may be used as backups in case of failure of fibre or other links.
  • New business models and vertical integration: Many transport companies are looking to extend their reach into adjacent industries, or via vertical integration within their own domain. Companies such as FedEx and UPS, as well as eCommerce players such as Amazon, have their own fleets of planes and on- or near-airport warehouse facilities. Rail companies are exploring new mixed use retail and office properties integrated with stations. Some are deploying dedicated energy infrastructure, ranging from solar farms to hydrogen electrolysis. All these facilities may be built as greenfield developments, with the project considering the latest connectivity options for IoT or other uses.
  • Enhanced customer / passenger experience: Both individual travellers and freight shippers have an expanded set of choices for travel and transport of goods. They make decisions not just on price, but also reliability / predictability, as well as up-to-date information about status and disruptions. There are expectations for easy Internet access, online portals for reservation and check-in, use of digital sign-boards onsite, accurate cargo tracking and condition-monitoring, simpler border and customs processes, and safe/secure travel environments. They also expect multi-modal transport to be made easier, with interchanges made more convenient and transparent for both goods and personal travel.

5G standalone (SA) core: Why and how telcos should keep going

Major 5G Standalone deployments are experiencing delays…

There is a widespread opinion among telco industry watchers that deployments of the 5G Standalone (SA) core are taking longer than originally expected. It is certainly the case that some of the world’s leading operators, and telco cloud innovators, are taking their time over these deployments, as illustrated below:

  • AT&T: Has no current, publicly announced deadline for launching its 5G SA core, which was originally expected to be deployed in mid-2021.
  • Deutsche Telekom: Launched an SA core in Germany on a trial basis in September 2022, having previously acknowledged that SA was taking longer than originally expected. In Europe, the only other opco that is advancing towards commercial deployment is Magenta Telekom in Austria. In 2021, the company cited various delay factors, such as 5G SA not being technically mature enough to fulfil customers’ expectations (on speed and latency), and a lack of consumer devices supporting 5G SA.
  • Rakuten Mobile: Was expected to launch an SA core co-developed with NEC in 2021. But at the time of writing, this had still not launched.
  • SK Telecom: Was originally expected to launch a Samsung-provided SA core in 2020. However, in November 2021, it was announced that SK Telecom would deploy an Ericsson converged Non-standalone (NSA) / SA core. By the time of writing, this had still not taken place.
  • Telefónica: Has carried out extensive tests and pilots of 5G SA to support different use cases but has no publicly announced timetable for launching the technology commercially.
  • Verizon: Originally planned to launch its SA core at the end of 2021. But this was pushed back to 2022; and recent pronouncements by the company indicate a launch of commercial services over the SA core only in 2023.
  • Vodafone: Has launched SA in Germany only, not in any of its other markets; and even then, nationwide SA coverage is not expected until 2025. An SA core is, however, expected to be launched in Portugal in the near future, although no definite deadline has been announced. A ‘commercial pilot’ in three UK cities, launched in June 2021, had still not resulted in a full commercial deployment by the time of writing.

…but other MNOs are making rapid progress

In contrast to the above catalogue of delay, several other leading operators have made considerable progress with their standalone deployments:

  • DISH: Launched its SA core- and open RAN-based network in the US, operated entirely over the AWS cloud, in May 2022. The initial population coverage of the network was required to be 20%. This is supposed to rise to 70% by June 2023.
  • Orange: Proceeding with a Europe-wide roll-out, with six markets expected to go live with SA cores in 2023.
  • Saudi Telecom Company (STC): Has launched SA services in two international markets, Kuwait (May 2021) and Bahrain (May 2022). Preparations for a launch in Saudi Arabia were ongoing at the time of writing.
  • Telekom Austria Group (A1): Rolling out SA cores across four markets in Central Europe (Bulgaria, Croatia, Serbia and Slovenia), although no announcement has been made regarding a similar deployment in its home market of Austria. In June 2022, A1 also carried out a PoC of end-to-end, SA core-enabled network slicing, in partnership with Amdocs.
  • T-Mobile US: Has reportedly migrated all of its mobile broadband traffic over to its SA core, which was launched back in 2020. It also launched one of the world’s first voice-over-New Radio (VoNR) services, run over the SA core, in parts of two cities in June 2022.
  • Zain (Kuwait): Launched SA in Saudi Arabia in February 2022, while a deployment in its home market was ongoing at the time of writing.
  • There are also a number of trials, and prospective and actual deployments, of SA cores over the public cloud in Europe. These are serving the macro network, not edge or private-networking use cases. The most notable examples include Magenta Telekom (Deutsche Telekom’s Austrian subsidiary, partnering with Google Cloud); Swisscom (partnering with AWS); and Working Group Two (wgtwo) – a Cisco and Telenor spin-off – that offers a multi-tenant, cloud-native 5G core delivered to third-party MNOs and MVNOs via the AWS cloud.
  • The three established Chinese MNOs are all making rapid progress with their 5G SA roll-outs, having launched in either 2020 (China Telecom and China Unicom) or 2021 (China Mobile). The country’s newly launched, fourth national player, Broadnet, is also rolling out SA. However, it is not publicly known what share of the country’s reported 848 million-odd 5G subscribers (at March 2022) were connected to SA cores.
  • At least eight other APAC operators had launched 5G SA-based services by July 2022, including KT in South Korea, NTT Docomo and SoftBank in Japan and Smart in the Philippines.

Many standalone deployments in the offing – but few fixed deadlines

So, 5G standalone deployments are definitely a mixed bag: leading operators in APAC, Europe, the Middle East and North America are deploying and have launched at scale, while other leading players in the same regions have delayed launches, including some of the telcos that have helped drive telco cloud as a whole over the past few years, e.g. AT&T, Deutsche Telekom, Rakuten, Telefónica and Vodafone.

In the July 2022 update to our Telco Cloud Deployment Tracker, which contained a ‘deep dive’ on 5G core roll-outs, we presented an optimistic picture of 5G SA deployments. We pointed out that the number of SA and converged NSA / SA cores. We expect to be launched in 2022 outnumbered the total of NSA deployments. However, as illustrated in the figure below, SA and converged NSA/SA cores are still the minority of all 5G cores (29% in total).

We should also point out that some of the SA and converged NSA / SA deployments shown in the figure below are still in progress and some will continue to be so in 2023. In other words, the launch of these core networks has been announced and we have therefore logged them in our tracker, but we expect that the corresponding deployments will be completed in the remainder of 2022 or in 2023, based on a reasonable, typical gap between when the deployments are publicly announced and the time it normally takes to complete them. If, however, more of these predicted deployments are delayed as per the roll-outs of some of leading players listed above, then we will need to revise down our 2022 and 2023 totals.

How telcos can provide a tonic for transport

5G can help revolutionise public transport

With the advent of 5G, STL Partners believes telcos have a broad opportunity to help coordinate better use of the world’s resources and assets, as outlined in the report: The Coordination Age: A third age of telecoms. Reliable and ubiquitous connectivity can enable companies and consumers to use digital technologies to efficiently allocate and source assets and resources.

In urban and suburban transport markets, one precious resource is in short supply – space. Trains can be crowded, roads can be congested and there may be nowhere to park. Following the enormous changes in working patterns in the wake of the pandemic, both individuals and policymakers are reviewing their transport choices.

This report explores how the concept of mobility-as-a-service (MaaS) is evolving, while outlining the challenges facing those companies looking to transform public transport. In particular, it considers how telcos and 5G could support the development and deployment of automated shuttle buses, which are now beginning to appear on the world’s roads. Whereas self-driving cars are taking much longer to develop than their proponents expected, automated shuttle buses look like a more realistic mid-term prospect. Running on relatively short set routes, these vehicles are easier to automate and can be monitored/controlled by dedicated connectivity infrastructure.

This report also examines the role of 5G connectivity in other potentially-disruptive transport propositions, such as remotely controlled hire cars, passenger drones and flying cars, which could emerge over the next decade. It builds on previous STL Partners research including:

Where is transport headed?

Across the world, transport is in a state of flux. Growing congestion, the pandemic, concerns about air quality and climate change, and the emergence of new technologies are taking the transport sector in new directions. Urban planners have long recognised that having large numbers of half-empty cars crawling around at 20km/hour looking for somewhere to park is not a good use of resources.

Experimentation abounds. Many municipalities are building bike lanes and closing roads to try and encourage people to get out of their cars. In response, sales of electric bikes and scooters are rising fast. The past 10 years has also seen a global boom (followed by a partial bust) in micro-mobility services – shared bikes and scooters. Although they haven’t lived up to the initial hype, these sharing economy services have become a key part of the transport mix in many cities (for more on this, see the STL Partners report: Can telcos help cities combat congestion?).

Indeed, these micro-mobility services may be given a shot in the arm by the difficulties faced by the ride hailing business. In many cities, Uber and Lyft are under intense pressure to improve their driver proposition by giving workers more rights, while complying with more stringent safety regulations. That is driving costs upwards. Uber had hoped to ultimately replace human drivers with self-driving vehicles, but that now looks unlikely to happen in the foreseeable future. Tesla, which has always been bullish about the prospects autonomous driving, keeps having to revise its timelines backwards.

Tellingly, the Chinese government has pushed back a target to have more than half of new cars sold to have self-driving capabilities from 2020 to 2025. It blamed technical difficulties, exacerbated by the coronavirus pandemic, in a 2020 statement issued by National Development and Reform Commission and the Ministry of Industry and Information Technology.

Still, self-driving cars will surely arrive eventually. In July, Alphabet (Google’s parent) reported that its experimental self-driving vehicle unit Waymo continues to grow. “People love the fully autonomous ride hailing service in Phoenix,” Sundar Pichai, CEO Alphabet and Google, enthused. “Since first launching its services to the public in October 2020, Waymo has safely served tens of thousands of rides without a human driver in the vehicle, and we look forward to many more.”

In response to analyst questions, Pichai added: “We’ve had very good experience by scaling up rides. These are driverless rides and no one is in the car other than the passengers. And people have had a very positive experience overall. …I expect us to scale up more through the course of 2022.”

More broadly, the immediate priority for many governments will be on greening their transport systems, given the rising public concern about climate change and extreme weather. The latest report from the Intergovernmental Panel on Climate Change calls for “immediate, rapid and large-scale reductions in greenhouse gas emissions” to stabilise the earth’s climate. This pressure will likely increase the pace at which traditional components of the transport system become all-electric – cars, motorbikes, buses, bikes, scooters and even small aircraft are making the transition from relying on fossil fuel or muscle power to relying on batteries.

The rest of this 45-page report explores how public transport is evolving, and the role of 5G connectivity and telcos can play in enabling the shift.

Private networks: Lessons so far and what next

The private networks market is rapidly developing

Businesses across a range of sectors are exploring the benefits of private networks in supporting their connected operations. However, there are considerable variations between national markets, reflecting spectrum and other regulatory actions, as well as industrial structure and other local factors. US, Germany, UK, Japan and the Nordics are among the leading markets.

Enterprises’ adoption of digitalisation and automation programmes is growing across various industries. The demand from enterprises stems from their need for customised networks to meet their vertical-specific connectivity requirements – as well as more basic considerations of coverage and cost of public networks, or alternative wireless technologies.

On the supply side, the development in cellular standards, including the virtualisation of the RAN and core elements, the availability of edge computing, and cloud management solutions, as well as the changing spectrum regulations are making private networks more accessible for enterprises. That said, many recently deployed private cellular networks still use “traditional” integrated small cells, or major vendors’ bundled solutions – especially in conservative sectors such as utilities and public safety.

Many new players are entering the market through different vertical and horizontal approaches and either competing or collaborating with traditional telcos. Traditional telcos, new telcos (mainly building private networks or offering network services), and other stakeholders are all exploring strategies to engage with the market and assessing the opportunities across the value chain as private network adoption increases.

Following up on our 2019 report Private and vertical cellular networks: Threats and opportunities, we explore the recent developments in the private network market, regulatory activities and policy around local and shared spectrum, and the different deployment approaches and business cases. In this report we address several interdependent elements of the private networks landscape

Enter your details below to request an extract of the report

What is a private network?

A private network leverages dedicated resources such as infrastructure and spectrum to provide precise coverage and capacity to specific devices and user groups. The network can be as small as a single radio cell covering a single campus or a location such as a manufacturing site (or even a single airplane), or it can span across a wider geographical area such as a nationwide railway network or regional utility grids.

Private networks is an umbrella term that can includes different LAN (or WAN) connectivity options such as Wi-Fi and LPWAN. However, more commonly, the term is being associated with private cellular networks based on 3GPP mobile technologies, i.e. LTE or 5G New Radio (NR).

Private networks are also different from in-building densification solutions like small cells and DAS which extend the coverage of public network or strengthen its capacity indoors or in highly dense locations. These solutions are still part of the public network and do not support customised control over the local network access or other characteristics. In future, some may support local private networks as well as public MNOs’ services.

Besides dedicated coverage and capacity, private networks can be customised in other aspects such as security, latency and integration with the enterprise internal systems to meet business specific requirements in ways that best effort public networks cannot.

Unlike public networks, private networks are not available to the public through commercially available devices and SIM cards. The network owner or operator controls the authorisation and the access to the network for permissioned devices and users. These definitions blur somewhat if the network is run by a “community” such as a municipality.

Typically, devices will not work outside the boundaries of their private network. That is a requirement in many use cases, such as manufacturing, where devices are not expected to continue functioning outside the premise. However, in a few areas, such as logistics, solutions can include the use of dual-SIM devices for both public and private networks or the use of other wide area technologies such as TETRA for voice. Moreover, agreements with public networks to enable roaming can be activated to support certain service continuity outside the private network boundaries.

While the technology and market are still developing, several terms are being used interchangeably to describe 3GPP private networks such dedicated networks, standalone networks, campus networks, local networks, vertical mobile network and non-public networks (NPN) as defined by the 3GPP.

The emergence of new telcos

Many telcos are not ready to support private networks demands from enterprises on large scale because they lack sufficient resources and expertise. Also, some enterprises might be reluctant to work with telcos for different reasons including their concerns over the traditional telcos’ abilities in vertical markets and a desire to control costs. This gap is already catalysing the emergence of new types of mobile network service providers, as opposed to traditional MNOs that operate national or regional public mobile networks.

These players essentially carry out the same roles as traditional MNOs in configuring the network, provisioning the service, and maintaining the private network infrastructure. Some of them may also have access to spectrum and buy network equipment and technologies directly from network equipment vendors. In addition to “new telcos” or “new operators”, other terms have been used to describe these players such as specialist operators and alternative operators. Throughout this report, we will use new telcos or specialist operators when describing these players collectively and traditional/public operators when referring to typical wide area national mobile network provider. New players can be divided into the following categories:

Driving the agility flywheel: the stepwise journey to agile

Agility is front of mind, now more than ever

Telecoms operators today face an increasingly challenging market, with pressure coming from new non-telco competitors, the demands of unfamiliar B2B2X business models that emerge from new enterprise opportunities across industries and the need to make significant investments in 5G. As the telecoms industry undergoes these changes, operators are considering how best to realise commercial opportunities, particularly in enterprise markets, through new types of value-added services and capabilities that 5G can bring.

However, operators need to be able to react to not just near-term known opportunities as they arise but ready themselves for opportunities that are still being imagined. With such uncertainty, agility, with the quick responsiveness and unified focus it implies, is integral to an operator’s continued success and its ability to capitalise on these opportunities.

Traditional linear supply models are now being complemented by more interconnected ecosystems of customers and partners. Innovation of products and services is a primary function of these decentralised supply models. Ecosystems allow the disparate needs of participants to be met through highly configurable assets rather than waiting for a centralised player to understand the complete picture. This emphasises the importance of programmability in maximising the value returned on your assets, both in end-to-end solutions you deliver, and in those where you are providing a component of another party’s system. The need for agility has never been stronger, and this has accelerated transformation initiatives within operators in recent years.

Concepts of agility have crystallised in meaning

In 2015, STL Partners published a report on ‘The Agile Operator: 5 key ways to meet the agility challenge’, exploring the concept and characteristics of operator agility, including what it means to operators, key areas of agility and the challenges in the agile transformation. Today, the definition of agility remains as broad as in 2015 but many concepts of agility have crystallised through wider acceptance of the importance of the construct across different parts of the organisation.

Agility today is a pervasive philosophy of incremental innovation learned from software development that emphasises both speed of innovation at scale and carrier-grade resilience. This is achieved through cloud native modular architectures and practices such as sprints, DevOps and continuous integration and continuous delivery (CI/CD) – occurring in virtuous cycle we call the agility flywheel.

Six years ago, operators were largely looking to borrow only certain elements of cloud native for adoption in specific pockets within the organisation, such as IT. Now, the cloud model is more widely embraced across the business and telcos profess ambitions to become software-centric companies.

Same problem, different constraints

Cloud native is the most fundamental version of the componentised cloud software vision and progress towards this ideal of agility has been heavily constrained by operators’ underlying capabilities. In 2015, operators were just starting to embark on their network virtualisation journeys with barriers such as siloed legacy IT stacks, inelastic infrastructures and software lifecycles that were architecture constrained. Though these barriers continue to be a challenge for many, the operators at the forefront – now unhindered by these basic constraints – have been driving a resurgence and general acceleration towards agility organisation-wide, facing new challenges around the unknowns underpinning the requirements of future capabilities.

With 5G, the network itself is designed as cloud native from the ground up, as are the leading edge of enterprise applications recently deployed by operators, alleviating by design some of the constraints on operators’ ability to become more agile. Uncertainty around what future opportunities will look like and how to support them requires agility to run deep into all of an operators’ processes and capabilities. Though there is a vast raft of other opportunities that do not need cloud native, ultimately the market is evolving in this direction and operators should benchmark ambitions on the leading edge, with a plan to get there incrementally. This report looks to address the following key question:

The future of assurance: How to deliver quality of service at the edge

Why does edge assurance matter?

The assurance of telecoms networks is one of the most important application areas for analytics, automation and AI (A3) across telcos operations. In a previous report estimating the potential value of A3 across telcos’ core business, including networks, customer channels, sales and marketing, we estimated that service assurance accounts for nearly 10% of the total potential value of A3 (see the report A3 for telcos: Mapping the financial value). The only area of greater combined value was in resource management across telecoms existing networks and planned deployments.

Within service assurance, the biggest value buckets are self-healing networks, impact on customer experience and churn, and dynamic SLA management. This estimate was developed through a bottom up analysis of specific applications for automation, analytics and AI within each segment, and their potential to deliver cost savings or revenue uplift for an average sized telecoms operator (see the original report for the full methodology).

While this previous research demonstrates there is significant value for telcos in improving assurance on their legacy networks, over the next five years edge assurance will become an increasingly important topic for operators.

What we mean by edge assurance is the new capabilities operators will require to enable visibility across much more distributed, cloud-based networks, and monitoring of a wider and more dynamic range of services and devices, in order to deliver high quality experience and self-healing networks. This need is driven by operators’ accelerating adoption of virtualisation and software-defined networking, for example with increasing experimentation and excitement around open RAN, as well as some operators’ ambitions to play a significant role in the edge computing market (see our report Telco edge computing: How to partner with hyperscalers for analysis of telcos’ ambitions in edge computing).

To give an idea of the scale of the challenge ahead of operators in assuring increasingly distributed network functions and infrastructure, STL Partners’ expects a Tier-1 operator will deploy more than 8,000 edge servers to support virtual RAN by 2025 (see Building telco edge infrastructure: MEC, private LTE and vRAN for the full forecasts).

Given this dramatic shift in network operations, without new edge assurance capabilities:

  • A telco will not be able to understand where issues are occurring across the (virtualised) network and the underlying infrastructure, and diagnose the root cause
  • The promises of cost saving and better customer experience from self-healing networks will not be fully realised in next-generation networks
  • Potential revenue generators such as network slicing and URLLC will be of limited value to customers if the telco can’t offer sufficient SLAs on reliability, latency and visibility
  • It will not be possible to make promises to ecosystem partners around service quality.

Despite the significant number of unknowns in the future of telco activities around 5G, IoT and edge computing, this research ventures a framework to allow telcos to plan for their future service assurance needs. The first section describes the drivers affecting telcos decision-making around the types of assurance that they need at the edge. The second sets out products and capabilities that will be required and types of assurance products that telcos could create and monetise.

5G: Bridging hype, reality and future promises

The 5G situation seems paradoxical

People in China and South Korea are buying 5G phones by the million, far more than initially expected, yet many western telcos are moving cautiously. Will your company also find demand? What’s the smart strategy while uncertainty remains? What actions are needed to lead in the 5G era? What questions must be answered?

New data requires new thinking. STL Partners 5G strategies: Lessons from the early movers presented the situation in late 2019, and in What will make or break 5G growth? we outlined the key drivers and inhibitors for 5G growth. This follow on report addresses what needs to happen next.

The report is informed by talks with executives of over three dozen companies and email contacts with many more, including 21 of the first 24 telcos who have deployed. This report covers considerations for the next three years (2020–2023) based on what we know today.

“Seize the 5G opportunity” says Ke Ruiwen, Chairman, China Telecom, and Chinese reports claimed 14 million sales by the end of 2019. Korea announced two million subscribers in July 2019 and by December 2019 approached five million. By early 2020, The Korean carriers were confident 30% of the market will be using 5G by the end of 2020. In the US, Verizon is selling 5G phones even in areas without 5G services,  With nine phone makers looking for market share, the price in China is US$285–$500 and falling, so the handset price barrier seems to be coming down fast.

Yet in many other markets, operators progress is significantly more tentative. So what is going on, and what should you do about it?

5G technology works OK

22 of the first 24 operators to deploy are using mid-band radio frequencies.

Vodafone UK claims “5G will work at average speeds of 150–200 Mbps.” Speeds are typically 100 to 500 Mbps, rarely a gigabit. Latency is about 30 milliseconds, only about a third better than decent 4G. Mid-band reach is excellent. Sprint has demonstrated that simply upgrading existing base stations can provide substantial coverage.

5G has a draft business case now: people want to buy 5G phones. New use cases are mostly years away but the prospect of better mobile broadband is winning customers. The costs of radios, backhaul, and core are falling as five system vendors – Ericsson, Huawei, Nokia, Samsung, and ZTE – fight for market share. They’ve shipped over 600,000 radios. Many newcomers are gaining traction, for example Altiostar won a large contract from Rakuten and Mavenir is in trials with DT.

The high cost of 5G networks is an outdated myth. DT, Orange, Verizon, and AT&T are building 5G while cutting or keeping capex flat. Sprint’s results suggest a smart build can quickly reach half the country without a large increase in capital spending. Instead, the issue for operators is that it requires new spending with uncertain returns.

The technology works, mostly. Mid-band is performing as expected, with typical speeds of 100–500Mbps outdoors, though indoor performance is less clear yet. mmWave indoor is badly degraded. Some SDN, NFV, and other tools for automation have reached the field. However, 5G upstream is in limited use. Many carriers are combining 5G downstream with 4G upstream for now. However, each base station currently requires much more power than 4G bases, which leads to high opex. Dynamic spectrum sharing, which allows 5G to share unneeded 4G spectrum, is still in test. Many features of SDN and NFV are not yet ready.

So what should companies do? The next sections review go-to-market lessons, status on forward-looking applications, and technical considerations.

Early go-to-market lessons

Don’t oversell 5G

The continuing publicity for 5G is proving powerful, but variable. Because some customers are already convinced they want 5G, marketing and advertising do not always need to emphasise the value of 5G. For those customers, make clear why your company’s offering is the best compared to rivals’. However, the draw of 5G is not universal. Many remain sceptical, especially if their past experience with 4G has been lacklustre. They – and also a minority swayed by alarmist anti-5G rhetoric – will need far more nuanced and persuasive marketing.

Operators should be wary of overclaiming. 5G speed, although impressive, currently has few practical applications that don’t already work well over decent 4G. Fixed home broadband is a possible exception here. As the objective advantages of 5G in the near future are likely to be limited, operators should not hype features that are unrealistic today, no matter how glamorous. If you don’t have concrete selling propositions, do image advertising or use happy customer testimonials.

5G network slicing: How to secure the opportunity

Network slicing is central to unlocking the 5G opportunity

There has understandably been a lot of talk and hype about 5G and network slicing in the telecoms industry. It promises to bring greater speeds, lower latency, greater capacity, ultra-reliability, greater flexibility in the network operations and more. It also pledges to support high device densities and to enable new services, new business and operational models as well as new vertical opportunities.

Given that the rollout of 5G networks is expected to involve a significant investment of hundreds of billions of dollars, there is a need to look at how it might address new business opportunities that previous generations of cellular networks could not. Many, including us, have argued that the consumer business case for 5G is limited, and that the enterprise segment is likely to represent the greater opportunity.

One highly anticipated aspect of 5G is that it will be built on virtualised infrastructure. Network functions will run as software in datacentres, rather than on dedicated appliances as in the past. This will mean that operators can deploy and make changes to functions with far greater flexibility than ever before. It also offers the promise of enabling multiple logical end-to-end networks – each intended to meet specific needs – to be “spun-up”, operated and retired as required, over the same shared hardware. Traditionally, achieving such a multi-service outcome would have required building dedicated stand-alone networks, which was rarely a viable proposition.  This capability is the essence of network slicing.

This report will explore the concept of network slicing and what it means for enterprise customers. It will have a particular focus on one aspect of network slicing through the enterprise perspective, that being security. The first section will cover how we define network slicing whilst the second will dive into what the enterprise security-related concerns are. We will then assess the implications of these concerns in the third section, before identifying ways that telcos can address these concerns in order to accelerate the adoption of network slicing.

Our findings in this report are informed by a wider STL Partners research programme that STL Partners has conducted with telcos and enterprises across several verticals, including transport, defence, utilities, logistics and smart cities.

Enterprise security concerns with network slicing are rooted in the fear of the new and unknown

Network slicing is inherently complex. Multiple networks being created over common infrastructure, each serving different customers, use cases and devices means that management and orchestration of network slices is something that telcos are still grappling with. It not only represents a change in technology but also a shift in the way that the network lifecycle is managed, which is new and unfamiliar to telcos and their enterprise customers. Current security protocols will not necessarily be equipped to cover many of the new dimensions that network slicing brings. This new shift in the way things work will result in various enterprise security concerns. Changes in the network architecture with slicing, with multiple logical networks each having their own resources and sharing others, also poses questions of how the security architecture needs to evolve in order to address new risks.

Enterprise customers define security as not only about preventing services being compromised by intentional malicious attacks, but also about preventing service degradation or disruption due to unintentional operational or technical failures and/or negligence, unplanned breakdowns etc. Due to the interdependence of slices, even if a fault occurrence happens, it could consume resources in one slice, just like an attack would, which would affect the reliability or lifecycle of other network slices that share the same resources. Regardless of how the performance of a slice gets affected, whether it is by a malicious attack, a natural disaster, a bug or unintentional negligence, the consequences are ultimately the same. These are all, in some way, related to security. Therefore, when considering security, we need to think beyond potential intentional malicious attack but also unintentional negligence and unplanned events.

What if my network slice gets compromised? What if another slice gets compromised? What if another slice is eating up resources?

We outline these three key questions that enterprises have around their security concerns, as potential tenants of network slices, in the body of the report.

5G and MVNOs: Slicing up the wholesale market

Introduction

How will 5G MNVO models differ from what’s gone before? MVNOs occupy an important set of market niches in the mobile industry, ranging from low-cost generic consumer propositions by discount retail brands, through to some of the most advanced mobile offers, based on ingenious service-level innovation.

The importance and profile of MVNOs varies widely by country and target market segments.  Worldwide, there are around 250 million consumer subscribers using virtual operators’ branded services. IoT-focused MVNOs add many more. In many developed markets, MVNOs account for around 10-15% of subscribers, although in less-mature markets they are often not present at all, or are below 5%.

In Europe, the most mature region, there are around 100m subscribers, focused particularly on German and UK markets. Globally, MVNO revenues are estimated at around $70bn annually – a figure expected to grow to over $100bn in coming years, as markets such as China – which already has over 60m MVNO subscribers – gain more traction, bolstered by regulatory enthusiasm. IoT-centric and enterprise MVNOs are also growing in importance and sophistication, particularly for cross-border connectivity management.

While many MVNOs are aimed at lower-end consumers, with discounted packages under retail, banking or other brands, plenty more are more sophisticated and higher-ARPU propositions. Some fixed/cable operators want a mobile wholesale offer to expand into quad-play bundles. Increasingly, the MVNO model is going far beyond mass-market consumer offers, towards IoT and enterprise use-cases, that can add extra services and functions in the network or SIM.

Some 4G-only mobile operators have 3G MVNO arrangements for customers moving beyond their infrastructure footprint. Google has its pioneering Fi MVNO service, which switches users between multiple telcos’ infrastructures – and which is perhaps a testbed for its broader core/NFV ambitions. A variety of frequent-travellers or enterprise users seek customised plans with extra features, that mass-market MNOs cannot provide. In addition, many IoT connections are also provided by third parties that repackage MNOs’ network connectivity, often to provide global coverage across multiple underlying networks, tailored to specific segments or verticals. For example, Cubic Telecom, an automotive-focused CSP, is part-owned by Audi.

document.write(‘‘);

Operating with a variety of different business models and technical architectures, MVNOs are also relevant to mobile markets’ competitive functioning, especially as larger networks consolidate. Regulators vary in the degree to which they encourage virtual operators’ establishment and operation.

Some MVNOs, described as “full” or “thick” operate their own core networks, while other “light” or “thin” providers are essentially resellers, usually with their own billing platform but little more. Confusingly, some avoid the use of the term MVNO, especially in the IoT arena, often just describing themselves as offering “managed connectivity” or similar phrases.

Figure 1: Thick vs thin MVNOs and resellers

This all presents a challenge for normal mobile operators – at one level, they want the extra reach and scale, using MVNOs as channels into extra customer groups they cannot easily reach themselves. They may even want their own MVNO operations in countries outside their licensed footprint – TurkCell and China Mobile are examples of this. But they also worry that as MVNOs go beyond resale, they start to capture additional value in certain lucrative niches, or worse, become an “abstraction layer”, aggregating and commoditising multiple underlying networks, facilitating arbitrage – especially by using eSIM or multi-IMSI approaches. Google Fi has raised eyebrows in this regard, and Apple has long been feared for wanting to create an MVNO/AppStore hybrid to resell network capacity.

That said, even simple MVNO operations are not that simple. Setting up billing systems, legal agreements, network integrations and other tasks is still complex for a non-telecoms firm like a retailer or sports/entertainment brand. A parallel ecosystem of specialised software vendors, systems-integrators and “MVNO platforms” has evolved, with subtly-different types of organisation called MVNA (mobile virtual network aggregator) and MVNE (mobile virtual network enabler) doing the technical heavy-lifting for brands or other marketing organisations to develop specialised – and often tiny – MVNOs.

What is uncertain is how much of this changes with 5G – either because of innate technical challenges of the new architecture, or because of parallel evolutions like network virtualisation. These could prove to be both enablers and inhibitors for different types of MVNO, as well as changing the competitive / cannibalisation dynamics for their host providers.

This briefing document describes the current state-of-play of the MVNO landscape, and the shifts in both business model and technology that are ongoing. It considers the different types of MVNO, and how they are likely to intersect with the new 5G world that is set to emerge over the next decade.

AR/VR: Won’t move the 5G needle

Introduction

This report explores the potential impact of virtual reality (VR) and augmented reality (AR) on the lives of consumers. It considers how quickly these technologies will go mass market and the implications for telcos, including those with their own entertainment proposition and those operators whose networks act as a conduit for other companies’ content.

Widespread use of VR and/or AR could fuel another major step-change in the traffic travelling over telecoms networks. All VR apps and many AR apps will require vast amounts of data to be processed to render the necessary digital images. In short, telecoms operators could and should benefit from mass-market adoption of VR and AR.

In the consumer market – the primary focus of the research stream for which this report was written – the promise of VR and AR is that they will transform digital entertainment and communications. In the 2015 report Amazon, Apple, Facebook, Google, Netflix: Whose Digital Content is King?, STL Partners identified the rise of increasingly immersive games and interactive videos enabled by VR and/or AR as one of the six key trends that could disrupt the entertainment industry.

If it lives up to its hype, VR could blur the line between live entertainment and the living room. The ultimate promise of VR is that people will be able to enjoy a movie or sports event from the inside, choosing from multiple viewpoints within a 360-degree video stream, potentially placing themselves in the midst of the action. For example, a consumer could use VR to “sit” next to the conductor at a classical music concert or alongside a manager at a football match, and hear every word he or she utters. They may even be able to experience a sports event from the perspective of an athlete by streaming live footage from mini-cameras mounted on helmets or other attire. Although still very expensive, VR production technology is already being used to create immersive games and interactive movies, as well as interactive documentaries and educational programmes.

Developing in parallel with VR, AR calls for digital graphics to be superimposed on live images of the real world. This can be used to create innovative new games, such as the 2016 phenomenon Pokemon Go, and educational and informational tools, such as travel guides that give you information about the monument you are looking at. At live sports events, spectators could use AR software to identify players, see how fast they are running, check their heart rates and call up their career statistics.

This report draws the following distinction between VR and AR

  • Virtual reality: use of an enclosed headset for total immersion in a digital 3D world.
  • Augmented reality: superimposition of digital graphics into the real world via a camera viewfinder, a pair of glasses or onto a screen fixed in the real world.

Note, an advanced form of AR is sometimes referred to as mixed reality. In this case, fully interactive digital 3D objects are superimposed on the real world, effectively mixing virtual objects and people with physical objects and people into a seamless interactive scene. For example, an advanced telepresence service could project a live hologram of the person you are talking to into the same room as you.

The net effect is that both live and living room entertainment could become much more personalised and interactive, particularly as bandwidth, latency, graphics processing and rendering technology all improve.

In time, mixed-reality services are likely to become almost universally adopted in the developed world. They will become a valuable aid to everyday living, providing the user with information about whatever they are looking at, either on a transparent screen on a pair of glasses or through a wireless earpiece. Engineers, for example, will use the technology to identify individual parts and detect faults, while consumers will rely on AR to retrieve information about whatever they are looking at, whether that be the route of an approaching bus, the menu of a nearby restaurant or the fat and salt content of a ready meal.

Autonomous cars: Where’s the money for telcos?

Introduction

Connected cars have been around for about two decades. GM first launched its OnStar in-vehicle communications service in 1996. Although the vast majority of the 1.4 billion cars on the world’s roads still lack embedded cellular connectivity, there is growing demand from drivers for wireless safety and security features, and streamed entertainment and information services. Today, many people simply use their smartphones inside their cars to help them navigate, find local amenities and listen to music.

The falling cost of cellular connectivity and equipment is now making it increasingly cost-effective to equip vehicles with their own cellular modules and antenna to support emergency calls, navigation, vehicle diagnostics and pay-as-you-drive insurance. OnStar, which offers emergency, security, navigation, connections and vehicle manager services across GM’s various vehicle brands, says it now has more than 11 million customers in North America, Europe, China and South America. Moreover, as semi-autonomous cars begin to emerge from the labs, there is growing demand from vehicle manufacturers and technology companies for data on how people drive and the roads they are using. The recent STL Partners report, AI: How telcos can profit from deep learning, describes how companies can use real-world data to teach computers to perform everyday tasks, such as driving a car down a highway.

This report will explore the connected and autonomous vehicle market from telcos’ perspective, focusing on the role they can play in this sector and the business models they should adopt to make the most of the opportunity.

As STL Partners described in the report, The IoT ecosystem and four leading operators’ strategies, telcos are looking to provide more than just connectivity as they strive to monetise the Internet of Things. They are increasingly bundling connectivity with value-added services, such as security, authentication, billing, systems integration and data analytics. However, in the connected vehicle market, specialist technology companies, systems integrators and Internet players are also looking to provide many of the services being targeted by telcos.

Moreover, it is not yet clear to what extent the vehicles of the future will rely on cellular connectivity, rather than short-range wireless systems. Therefore, this report spends some time discussing different connectivity technologies that will enable connected and autonomous vehicles, before estimating the incremental revenues telcos may be able to earn and making some high-level recommendations on how to maximise this opportunity.

Service providers continue to face a decline in revenue

STL Partners has written for some time about the significant pressure faced by communications service providers (CSPs), both from operator rivals and players in adjacent sectors. Traditional telecoms revenue streams such as voice and messaging are shrinking, and as a result operator growth is slowing. Figure 1 shows that the average year-on-year revenue growth rate for 68 major telecoms groups worldwide has fallen since at least 2010.

Much of this decline is fuelled by the impact of new competition: digital players such as Google, Facebook (including Whatsapp), Microsoft (including Skype and Skype-for-business) and Netflix, who are equipped to provide their own digital services, including voice- and messaging-enabled applications, without the headache of maintaining capital-intensive network infrastructure. It is now widely acknowledged that voice minutes and SMS bundles will continue to decline as a revenue stream as other players can offer the same, or better, capabilities ‘over-the-top’ to consumers and organisations for much less or free.

Data is not enough to ensure future growth

Of course, in order to use these new digital services, organisations and consumers do need network connectivity and, as a result, data consumption levels have shot up. Currently, the only players able to offer data connectivity are the communications service providers themselves, and therefore many have pointed to data as the primary source of new revenues which might offset the gap left by the decline in voice and messaging. In developed markets, in particular, some operators hope that it may be possible to ‘premiumise’ data services and drive higher average revenues per user (ARPUs). We do not believe that the evidence supports this and anticipate that plummeting data connectivity rates ($/MB) will neutralise growth in volumes resulting in low or no net growth in revenues.

In many developed markets, intense competition and strict regulation restricts the ability of operators to resist data price decline and squeeze more out of customers. Figure 5, for example, shows that despite mobile data consumption in the United Kingdom growing 243% between 2013 and 2015, ARPUs actually fell 4.5% over the period. More data, it is clear, does not automatically translate into more money.

In Figure 6 below, we show our revenue forecast for a telecoms operator offering converged fixed and mobile telecoms services to both enterprise and consumer customers in a developed market. In this conservative estimate, data revenues grow slightly, but not enough to offset voice and messaging revenues falling by half.

It is STL Partners’ belief that the path to sustainable telecoms growth lies not just in better monetising connectivity, but rather in telcos developing new capabilities of their own, continuously innovating and launching new products and services that more readily meet the needs of their customer base. It is only by doing so, and by leveraging new technology and network assets where possible, that telcos will be able to truly compete with digital players. In essence, communications service providers must either evolve to overcome commoditisation or to embrace it. Either way, they cannot continue business as usual.

Virtualisation and slicing: enablers for change?

STL Partners has written previously about Telco Cloud, a concept in which telcos redefine themselves by adopting cloud business platforms and practices (similar to internet and content players), alongside virtualisation of their core assets. This could lead to increased service agility, and the ability to create new, network-integrated services. In turn, this could drive new revenue growth.

Network virtualisation is still at an early stage, but its adoption is increasingly seen as inevitable. Operators worldwide are already deploying NFV/SDN technology, some setting ambitious virtualisation targets over time. The forthcoming 5G standards, as well as IoT technologies, are being developed with virtualisation in mind, and technology vendors are increasingly evolving their software offerings. If managed effectively, virtualisation could be the catalyst for the transformation towards the digital service provider.

One way in which virtualisation might enable this change is through the concept of ‘network slicing’, under which network operators would be able to operate multiple logically separate virtual networks over a single network infrastructure. This paper examines what network slicing might look like in practise, and what that could mean for CSPs.

Slicing: a vision for fundamental transformation

Defining slicing is not about the ‘what’, it’s the ‘how’

Network slicing is a term that has been discussed quietly in the industry for some time, but it has gained prominence more recently in parallel with the industry’s developing new 5G standards. Slicing has recently become the focus of a public disagreement between industry players involved in driving 5G standards. In essence, one group of operators and vendors are keen on accelerating New Radio (NR) standards in 5G, whereas another group see this as potentially undermining future standards in end-to-end slicing. A related debate also exists within operators between the core network and radio access teams, but that is neither new, nor surprising. These debates are not about slicing, since most parties appear to broadly agree on its potential, but more about how 5G will be introduced: as an evolution of 4G or as a completely new network.

A few considerations

In recent years, network slicing has also gained prominence as a way of creating unified 5G networks, which cover multiple very-different use-cases with a single infrastructure. Turning a necessity into a virtue, this technical “fix” is now being seen as a possible basis for extra capabilities and new services. However, many of the benefits could – and should – be achievable before 5G.

While network-slicing can in theory extend all the way through core networks and down to the radio connection, it is still subject to the laws of physics: if there is no coverage, poor RF propagation, or limited overall capacity, there is a hard limit to what performance can be guaranteed. There are also boundaries at the device, 3rd-party server/cloud interface, or where other networks interconnect, which mean that “end-to-end control” doesn’t always mean an entire system.

It’s important not to fall into the trap of thinking that because we have a slicing “hammer” that all problems start to look like “nails”. Telcos have many other approaches to future service creation and revenue expansion, that lie outside the core network. Content partnerships, vertical-industry solutions, in-home automation and new forms of connectivity all offer opportunities. If network-slicing does not reach its aspirations, there are still plenty of other options for the industry to prosper.

Independently of the 5G debate, slicing can be considered part of a wider trend (in both fixed and wireless networks) towards a more software-centric infrastructure leading to more flexible networks. As more network resources become virtual (rather than physical), operators could readily allocate resources to a particular ‘network slice.’ Hence, slicing is arguably really about the orchestration of operator assets and how an operator is able to effectively manage its network.

This vision affirms that the ‘one size fits all’ model will not applicable for the future where a diverse set of requirements will need to addressed with more customised services: from (enhanced) mobile broadband (eMBB), to ultra-low latency types (uRLLC), to low-power machine-type communications for IoT devices (mMTC).

Taking the work done by industry organisations, such as The Next Generation Mobile Networks (NGMN) Alliance , 5G Americas and the Open Networking Foundation (ONF) into consideration, STL Partners has developed the following definition for network slicing as the basis for this paper:

‘Network slicing is a mechanism to create and dynamically manage functionally-discrete virtualised networks over a common infrastructure’
