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.

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.

Telco-Driven Disruption: Hits & Misses (Part 1)

Introduction

Part of STL’s new Dealing with Disruption in Communications, Content and Commerce stream, this executive briefing explores the role of telcos in disrupting the digital economy. It analyses a variety of disruptive moves by telcos, some long-standing and well established, others relatively new. It covers telcos’ attempts to reinvent digital commerce in South Korea and Japan, the startling success of mobile money services in east Africa, BT’s huge outlay on sports content, AT&T’s multi-faceted smart home platform, Deutsche Telekom’s investments in online marketplaces and Orange’s innovative Libon communications service.

In each case, this briefing describes the underlying strategy, the implementation and the results, before setting out STL’s key takeaways. The conclusions section outlines the lessons other would-be disruptors can learn from telcos’ attempts to move into new markets and develop new value propositions.

Note, this report is not exhaustive. The examples it covers are intended to be representative. Part 2 of this report will analyse other telcos who have successfully disrupted adjacent markets or created new ones. In particular, it will take a close look at NTT DOCOMO, Japan’s leading mobile operator, which has built up a major revenue stream from new businesses.  DOCOMO reported a 13% year-on-year increase in revenues from its new businesses in the six months to September 30th 2014 to 363 billion Japanese yen (more than US$3 billion). Its target for the full financial year is 770 billion yen (almost US$6.5 billion). Revenues from its Smart Life suite of businesses, which provide consumers with advice, information, security, cloud storage and other lifestyle services, rose 18% to 205 billion yen in the six months to September 30th 2014, while its dmarket content store now has 7.8 million subscribers. In the six months to September 30th, the total value of dmarket transactions rose 30% year-on-year to 34.6 billion yen.

In South Korea, leading telco KT is trying to use smartphone-based apps and services to disrupt the digital commerce market, as are the leading U.K. and U.S. mobile operators through their respective Weve and Softcard joint ventures.  In the Philippines, Smart Communications and Globe Telecom have recast the financial services market by enabling people to send each other money using text messages.

Several major telcos are seeking to use their network infrastructure to change the game in the cloud services market. For example, U.S. telco Verizon has made a major push into cloud services, spending US$1.4 billion to acquire specialist Terremark in 2011. At the same time, Verizon and AT&T are having to respond to an aggressive play by T-Mobile USA to reshape the U.S. telecoms market with its Un-carrier strategy.

Some of these companies and their strategies are covered in other STL Partners reports, including:

Telcos can and do disrupt

In the digital economy, innovative start-ups, such as Spotify, Twitter, Instagram and the four big Internet platforms (Amazon, Apple, Facebook and Google) are generally considered to be the main agents of disruption. Start-ups tend to apply digital technologies in innovative new ways, while the major Internet platforms use their economies of scale and scope to disrupt markets and established businesses. These moves sometimes involve the deployment of new business models that can fundamentally change the modus operandi of entire industries, such as music, publishing and video gaming.

However, these digital natives don’t have a monopoly on disruption. So-called old economy companies do sometimes successfully disrupt either their own sector or adjacent sectors. In some cases, incumbents are actually well placed to drive disruption. As STL Partners has detailed in earlier reports, telcos, in particular, have many of the assets required to disrupt other industries, such as financial services, electronic commerce, healthcare and utilities. As well as owning the underlying infrastructure of the digital economy, telcos have extensive distribution networks and frequent interactions with large numbers of consumers and businesses.

Although established telcos have generally been cautious about pursuing disruption, several have succeeded in creating entirely new value propositions, effectively disrupting either their core business or adjacent industry sectors. In some cases, disruptive moves by telcos have primarily been defensive in that their main objective is to reduce churn in the core business. In other cases, telcos have gone on the offensive, moving into new markets in search of new revenues (see Figure 1).

The next section of this paper explores the disruptive moves in the top right hand corner of Figure 1 – those that have taken telcos into new markets and have had a significant financial impact on their businesses.

Offensive, major financial impact 

A classic disruptive play is to use existing assets and customer relationships to move into an adjacent market, open up a new revenue stream and build a major business. This is what Apple did with the iPhone and what Amazon did with cloud services. Several telcos have also followed this playbook. This section looks at three examples – SK Telecom’s SK Planet, Safaricom’s M-Pesa and KDDI’s au Smart Pass – and what other companies in the digital economy can learn from these largely successful moves. Unlike many disruptive moves by telcos, the three businesses covered in this section have had sufficient impact to properly register on investors’ radar screens. They have moved the needle for their parent’s telcos and given their investors confidence in their ability to innovate.

SK Planet – an ambitious mobile commerce play

Owned by SK Telecom, SK Planet is a major broker in South Korea’s world-leading mobile commerce market. It has developed several two-sided online services that are similar in some respects to those offered by Google. SK Planet operates the T Map, a turn-by-turn navigation service, the T Store Android app store, the Smart Wallet payment, loyalty and couponing service, the OK Cashbag loyalty marketing programme and the 11th St online marketplace.


Strategy

Taking advantage of South Koreans’ appetite for new technologies, SK Telecom is using its home market as a test bed for mobile commerce solutions that could be deployed more widely. As well as seeking to generate revenues from enabling payments, advertising, loyalty, couponing and other forms of direct marketing in South Korea, it is aiming to become a leading mobile commerce player in other markets in Asia and North America.

SK Telecom’s approach has been to launch services early and then refine these services in response to feedback from the Korean market. It launched a mobile couponing service, for example, as early as 2008. To reduce the impact of corporate bureaucracy, in 2011, SK Telecom placed its digital commerce activities into a separate company, called SK Planet. The new entity has since focused on the development of a two-sided platform that aims to provide consumers with convenient shopping channels and merchants and brands with a wide range of marketing solutions both online and in the bricks and mortar arena. Although its services are over-the-top, in the sense that they don’t require consumers to use SK Telecom, SK Planet continues to work closely with SK Telecom – its sole owner.

Downstream, SK Planet is trying to differentiate itself by putting consumers’ interests first, giving them considerable control and transparency over the digital marketing they receive. Upstream, SK Planet is putting a lot of emphasis on helping traditional bricks and mortars stores go digital and reverse so-called showrooming, so that consumers research products online, but actually buy them from bricks and mortar retailers.

SK Planet CEO Jinwoo So talks about enabling “Next Commerce” by which he means the seamless integration of online and bricks and mortar commerce.  “Just as Amazon became the global leader in e-commerce by revolutionizing the industry, SK Planet aims to
become the global ‘Next Commerce’ leader in the offline market by driving mobile innovation that will eventually
break down the walls which separate the online and offline worlds,” he says.

Estimating the offline commerce market in South Korea is worth 230 trillion won (more than 210 US billion dollars), SK Planet is aggressively adapting its existing digital commerce platforms, which are underpinned by SK Telecom’s network assets, for mobile commerce. It is also making extensive use of the big data generated by its existing platforms to hone its offerings.

At the 2014 Mobile World Congress, SK Planet CEO Jinwoo So outlined how SK Planet has worked closely with SK Telecom to develop algorithms that use customer data to predict churn and provide personalized recommendations and offers. “We combined the traditional data mining with text mining,” he said. “How people create the search criteria or the sites they visit, we came up with a very unique formula, which gives up much two times better performance than before. … In 11th street, we have achieved almost three times better performance by applying our recommendation engine, which we developed. Now we are trying to prove the ROI for marketing budgets for brands and merchants.”
