5G data traffic growth - the devil (FWA) is in the detail

This blog combines two separate, linked LinkedIn articles published in June 2023 on consecutive days. The original posts and comment threads are here and here.

Measuring #mobile data traffic is important for operators, vendors, and policymakers.

As I've said before, we should use *good* #metrics to measure the #telecoms industry, rather than just *easy* metrics. This post is an example of what I mean.

Yesterday, Ericsson released its latest Mobility Report. It's always an interesting trove of statistics on mobile subscribers, networks and usage, with extra topical articles, sometimes written by customers or guests.

While obviously it's very oriented to cellular technologies and has an optimistic pro-3GPP stance, it has a long pedigree and a lot of work goes into it. It's partly informed by private stats from Ericsson's real-world, in-service networks run by MNO customers.

This edition includes extra detail, such as breaking out fixed-wireless access & separating video traffic into VoD #streaming (eg Netflix) vs. social media like TikTok and YouTube.

It had plenty of golden "information nuggets". For instance, traffic density can be 500-1000x higher in dense urban locations than sparse rural areas. I'll come back to that another time.

Global mobile data grew 36% from Q1'22 to Q1'23. The full model online predicts 31% growth in CY2023, falling to just 15% in 2028, despite adding in AR/VR applications towards the end of the decade. That's a fairly rapid s-curve flattening.

For Europe, MBB data growth is predicted at 29% in 2023, falling to only 12% in 2028. That's a *really* important one for all sorts of reasons, and is considerably lower than many other forecasts.

But what really caught my eye was this "#FWA data traffic represented 21% of global mobile data traffic at the end of 2022". Further, it is projected to grow much faster than mobile broadband (MBB) and account for *30%* of total traffic in 2028, mostly #5G. When the famous "5G triangle" of use-cases was developed by ITU, it didn't even mention FWA.

However, the report didn't break out this split by region. So I decided to estimate it myself based on the regional split of FWA subscribers, which was shown in a graphic. I also extended the forecasts out to 2030.

I then added an additional segmentation of my own - an indoor vs outdoor split of MBB data. I've pegged this at 75% indoors, aligning with previous comments from Ericsson and others. Some indoor MBB is served by dedicated in-building wireless systems, and some is outdoor-to-indoor from macro RAN or outdoor small cells.

The result is fascinating. By the 2030, it is possible that over 40% of European 5G data traffic will be from FWA. Just 14% of cellular data will be for outdoor mobile broadband. So what's generating the alleged 5G GDP uplift?

That has massive implications for spectrum policy (eg on #6GHz) and proposed #fairshare traffic fees. It also highlights the broad lack of attention paid to indoor cellular and FWA.

Note: This is a quick, rough estimate, but it's the type of data we need for better decisionmaking. I hope to catalyse others to do similar analysis.

 


A separate second post then looked at the policy aspects of this:

Yesterday's post on mobile data traffic - and contribution from 5G FWA and indoor use - seems to have struck a chord. Some online and offline comments have asked about the policy implications.

There are several conclusions for regulators and telecoms/infrastructure ministries:

- Collect more granular data, or make reasoned estimates, of breakdowns of data traffic in your country & trends over time. As well as #FWA vs #MBB & indoor vs outdoor, there should be a split between rural / urban / dense & ideally between macro #RAN vs outdoor #smallcell vs dedicated indoor system. Break out rail / road transport usage.
- Develop a specific policy (or at least gather data and policy drivers) for FWA & indoor #wireless. That feeds through to many areas including spectrum, competition, consumer protection, #wholesale, rights-of-way / access, #cybersecurity, inclusion, industrial policy, R&D, testbeds and trials etc. Don't treat #mobile as mostly about outdoor or in-vehicle connectivity.
- View demand forecasts of mobile #datatraffic and implied costs for MNO investment / capacity-upgrade through the lens of detailed stats, not headline aggregates. FWA is "discretionary"; operators know it creates 10-20x more traffic per user. In areas with poor fixed #broadband (typically rural) that's potentially good news - but those areas may have spare mobile capacity rather than needing upgrades. Remember 4G-to-5G upgrade CAPEX is needed irrespective of traffic levels. FWA in urban areas likely competes with fibre and is a commercial choice, so complaints about traffic growth are self-serving.
- Indoor & FWA wireless can be more "tech neutral" & "business model neutral" than outdoor mobile access. #WiFi, #satellite and other technologies play more important roles - and may be lower-energy too. Shared / #neutralhost infrastructure is very relevant.
- Think through the impact of detailed data on #spectrum requirements and bands. In particular, the FWA/MBB & indoor splits are yet more evidence that the need for #6GHz for #5G has been hugely overstated. In particular, because FWA is "deterministic" (ie it doesn't move around or cluster in crowds) it's much more tolerant of using different bands - or unlicensed spectrum. Meanwhile indoor MBB can be delivered with low-band macro 5G, dedicated in-building systems (perhaps mmWave), or offloaded to WiFi. Using midband 5G and MIMO to "blast through walls" is not ideal use of either spectrum or energy.
- View 5G traffic data/forecasts used in so-called #fairshare or #costrecovery debates with skepticism. Check if discretionary FWA is inflating the figures. Question any GDP impact claims. Consider how much RAN investment is actually serving indoor users, maybe inefficiently. And be aware that home FWA traffic skews towards TVs and VoD #streaming (Netflix, Prime etc) rather than smartphone- or upload-centric social #video like TikTok & FB/IG.

Telecoms regulation needs good input data, not convenient or dramatic headline stats.

10 Principles for Telecoms Vendor Diversification in the UK & Beyond

This was originally published as one of my newsletter articles on LinkedIn. Click here for discussion and commentary & to subscribe. 

 Introduction

The UK is currently a hive of activity for government and regulatory involvement in telecoms. I can’t remember a time when so much emphasis has been put on my domain – from election commitments on gigabit broadband, to concerns over “high risk vendors” (HRVs) – notably Huawei.

This week has seen further progress through Parliament of the Telecom Security Bill (link) which makes telcos face legislation on cybersecurity and HRVs. There has also been the linked publication of the 5G Supply Chain Diversification Strategy (link), which ties the removal of Huawei gear with the government’s intentions to expand operators’ choice of other vendors.

I’m going to be spending considerably more time on the policy aspects of telecoms in coming months – not just my normal areas like spectrum, but more broadly the intersection with geopolitics, technology evolution and industrial strategy, competition and trade.

This article focuses on the diversification aspects - my thoughts on the published strategy, plus what I’d like to see in recommendations from the Task Force and policies from government in 2021. It’s a follow-on from my recent post on interoperability. Note: I’m not revisiting the HRV or Huawei issue here.  

I should stress that this isn’t just parochial and UK-specific - it has wider ramifications on the global telecom market, and links up with activities in Brussels, Washington and elsewhere, such as the US Open RAN Policy Coalition, and the EU’s cybersecurity “toolbox” and upcoming European Cybersecurity Strategy review.

Disclosure – my advisory clients span a broad range of UK and international organisations, from startups to large vendors, service providers of numerous types, investors and branches of government. I work with companies and organisations that enable closed macro & small-cell networks, Open RAN, Wi-Fi, satellite connectivity and more. As people who know me will attest, my opinions are my own – and attempts to influence them will often backfire, even if made by paying clients. In fact, people pay me because I regularly say things they don’t want to hear. I like saying “no”.

Background

 Even before the pandemic there was huge UK government engagement – and manifesto commitments - on “full fibre”, 5G mobile networks, sponsored testbeds & trials, and even satellite communications with the investment in OneWeb.

A lot of my own focus in recent years has been triggered by the Future Telecom Infrastructure Review in 2018, which kicked off the current regulatory enthusiasm for localised spectrum, enterprise/private cellular and neutral host networks – although other commentators had also advocated this for some time previously (*coughs modestly*).

In the last 6-12 months, there has been a specific focus on “supply chain diversification”, and a desire by policymakers to increase the number of equipment/software vendors in the market for network infrastructure. This isn’t new – the Government published its initial Telecom Supply Chain Review in mid-2019 – but it has lately taken on greater urgency.

The largest catalyst has been the recent action taken on Huawei and what that means for supply of equipment in the UK as a result, particularly for national 5G RAN build-outs by the four main UK MNOs BT, Vodafone, Telefonica O2 and 3UK.

The net result of this has been the establishment of the UK Telecoms Diversification Task Force as an advisory group (link), aligned with an internal project to develop a strategy and policy for broadening the vendor base, being run by DCMS (Department of Digital, Culture Media & Sport).

The new strategy document highlights what it sees as a duopoly of Nokia and Ericsson, especially for macro RAN gear, and suggests that if that continues it implies a risk to future resilience of the supply-chain. During the various Science & Technology committee hearings this year, there has been input from vendors, operators, security officials, task force members and others.

The discussion has largely been 5G-dominated, although the strategy document also mentions fixed-infrastructure diversification (subject to ongoing consultation and review). Many of the parliamentarians seem to think 5G is something special, and have bought into the “unicorn” visions of GDP uplift and “ubiquity”. (My regular readers know that 5G is “just another G” – an important upgrade, but not something which will change the world).

The strategy proposes three areas of action:

  • “Supporting incumbent suppliers” (Nokia and Ericsson) as major vendors, but suggests various approaches towards nudging them to greater levels of openness.
  • “Attracting new suppliers into the UK market” – this essentially means working out ways to get Samsung, NEC & Fujitsu more involved, as well as others. The parliamentary debate’s speakers also name-checked Mavenir, Parallel Wireless, Rakuten’s platform business and others.
  • “Accelerating open-interface solutions and deployment” – which refers more to the realm of industrial policy around Open RAN, and components such as semiconductors.

As you might imagine, I’ve got some fairly trenchant opinions on much of this.

Is the market that concentrated?

Clearly, the UK MNOs are today almost entirely dependent on Huawei, Nokia and Ericsson for their macro RAN deployments, although Samsung has previously been present in the 3UK’s 4G network, and Vodafone has recently started deploying gear from Mavenir in its Open RAN deployment.

However, some countries such as the US and Japan have maintained a greater diversity in macro RAN supply, despite a lack of Huawei gear - although there are some differences compared to the UK. Continued support of older 2G/3G services currently relying on combined “single RAN” infrastructures is a valid concern – and the Diversification report suggests it might be possible to sunset or improve interoperability there. The Samsung presentation and letter to the committee also had some suggestions about this (link).

I think there’s perhaps also a link to the historical “3GPP monoculture” in UK/Europe. Other regions had a mix of GSM, CDMA and local alternatives, which fostered greater supply fragmentation originally, which endured over time as the "single RAN" approach wasn't as much of an obvious win (or lock-in).

It is worth noting that there is already good diversity for private cellular networks and specific mobile products such as 4G/5G cores, indoor wireless and other niches such as fixed-wireless access. Many alternative suppliers are gaining traction first in rural and other “secondary” areas, rather than dense urban macro locations.

One aspect the government hasn’t appeared to consider is how much of the anticipated 5G “upside” (whether you believe the $billions GDP numbers or not) is conveniently located in these very contexts which have greater levels of supply diversity. Many of the expected new 5G applications are indoors (in factories, hospitals etc), or in sectors such as agriculture.

Another set of “advanced connectivity” applications have alternative technology options, especially over the 3-5 years it will take 5G to mature. WiFi 6/6E/7, LoRa, 60GHz FWA, new satellite constellations and proprietary platforms like Amazon Sidewalk all offer alternatives to 5G. Yet I still hear people talking about 5G for low-latency AR/VR in peoples’ homes when it’s obvious that 90%+ of that will use Wi-Fi, for multiple reasons.



Reading the report and listening to the debates, there seems to be a certain amount of hindsight here, with regrets that previous governments hadn’t thought through possible consolidation from three big cellular vendors to two, irrespective of which was taken out of the equation or how. Some speakers went back further, to the days of Nortel and Marconi, mourning the loss of greater diversity and national sovereign capability.

There’s also an implied sense of worry that one of the existing incumbents might make a mis-step. It’s notable that the “supporting incumbents” line was absent in January discussions, but was perhaps catalysed by Nokia’s 5G woes earlier in this year. The US Attorney General floating the possibility of a US company acquiring either Nokia or Ericsson, probably raised the stakes even further, even if that suggestion was rapidly shot down at the time.

Other concurrent drivers have related to Brexit, trade deals with Japan (and presumably EU, US and S Korea in future) and the enthusiasm of the current administration for more “industrial policy”. There is interest in state-aid for many areas of technology, ranging from hydrogen-powered aircraft (“Jet Zero”) to biotech to quantum computing, with the aim of improving the UK’s export and trading prospects in new and emerging areas. Telecoms technology needs to be seen in the context of a very expansive vision from artificial meat to nuclear fusion. (Wearing my futurist hat, I heartily approve of this).

Open RAN & disaggregation

Perhaps the least-cohesive part of the strategy document (and some initial actions like the testing and interoperability lab announcements) is the focus on Open RAN as the main saviour of supply-chain diversification. It got a huge amount of airtime in the DCMS report, as well as in politicians’ speeches.

In my view, Open RAN is similar to 5G more generally – important, but getting rather over-hyped. It’s going to be very important in future, but it's not the only game in town. Perhaps it will form the centrepiece of 6G, but for 5G macro – which is being deployed now – it’s going to be secondary, even if some of the Huawei rip/replace by 2027 uses it.

There seems to be quite a lot of disagreement between the MNOs as well – Vodafone is clearly a fan, while BT and 3UK seem more sceptical, with O2 somewhere in the middle.

I’m far from convinced that some of the detailed aspects in the document and annex – going as far as discussing eCPRI interfaces and 7.2 O-RAN splits – are the pivot-points for the overall diversification or resilience story. We don’t have TIP specs for OpenRAN 5G Massive MIMO yet, and may not get there for quite a while.

We’ll see a growing amount of vendor orientation on cloud and open RAN approaches anyway – Samsung, NEC and even Nokia are pursuing it. Ericsson and Huawei are being more diffident, but also seem to recognise that virtualisation is important, even if they’re not breaking open all bits of the RAN. Ericsson's recent Cloud RAN announcement could reasonably be described as "tentative" (link).

While there’s a lot of action and excitement with Rakuten, Dish and other greenfield networks, that doesn’t mean that operators in the UK or elsewhere would necessarily follow suit, even if they could do it tomorrow. It would be nice for the option to be there – but I’m a little concerned that the document asserts that interoperability should always be a default rather than a viable option. (If you haven’t seen my post on interop, have a scan through it here). Different operators have different views - and different legacy infrastructure.

Think of an analogy: should the government also suggest that Airbus planes should interoperate with Boeing avionics? Or, for that matter, how many of the advocates would accept Linux as the “default” OS for their laptops, rather than being able to choose Windows or MacOS if they prefer?

I expect we'll see a growing amount of Open RAN in rural and then perhaps suburban areas - but it's going to be a long time before it's common in existing MNOs' urban cores and high-density macro domains. It's an interesting platform for neutral host networks too, as the NEC trial points out. It is part of the overall “choice architecture” for future networks, but arguably the most interesting domains for advanced connectivity will get more choice / vendor competition from non-5G technology options. The normal 5G macro RAN is more about capacity for smartphone broadband, rather than clever new applications. 



What we should aim to see from future UK Diversification recommendations & policy

What comes next is the Diversification Task Force recommendations, which are expected early in 2021. This will feed into the policies and actions taken by the rest of government – potentially DCMS, although some have suggested aspects should reside with Ofcom, the security agencies or other departments.

As some external input, I thought I’d lay out some my own preferences, principles and what I’d like to see. (I may also submit more formal comments into the consultation process).

  • Clarity of purpose(s): There is a tendency in the report and parliamentary debate to conflate security, supply resilience, competition, innovation, export opportunity and other drivers for telecoms (de)regulation. All are valid concerns and thus represent areas for government to become involved – but any individual recommendations or rules should break out the underlying purpose(s) clearly. Obviously, few politicians or media commentators are experts in telecoms networks arcana – so communications across Westminster and beyond needs to be crisp, and misconceptions and misrepresentations pointed out swiftly. Soundbites and spin always get attention – but must be rooted in technical reality rather than convenience and media-friendliness.
  • Technology neutrality: While there are specific concerns about 5G RAN as it’s a major current focus of investment – and because the intelligence/core functions are increasingly distributed – it’s far from the only important telecom technology, or the only one with a concentrated supplier base. 4G mobile, fibre and fixed-line broadband infrastructure, satellite and assorted other wireless technologies should also be considered as part of diversification. There’s no major UK Wi-Fi player, for instance, which ideally would be rectified. At a component level, we should rightly be considering semiconductors, but also many areas of cloud and software elements involved in ever-more-virtualised telecom networks as well.
  • Business model neutrality: This links to my recent post on interoperability. Governments shouldn’t mandate either proprietary or interoperable interfaces, or vertically-integrated or disaggregated solutions – as long as there’s enough competition. Openness is good – but both highest-performance and lowest-cost options may involve “black boxes”. Open RAN (which in any case needs more careful definitions and comes in multiple variants) has huge promise, but shouldn’t be a political football either. We should be encouraging market forces to operate effectively, in the demand side of telecoms networks. Choice is imperative. (You could say the same about net neutrality: if customers have a choice of 10+ ISPs, it doesn't really matter if one of them sells "Ain'ternet" as long as it's accurately marketed & distinguished from the real thing).
  • Realistic time horizons & paths: Regular readers of my posts may have noticed increasing mentions of “path dependence”. Timelines matter. If there’s an awkward 4-year gap between promise and reality for a given technology, for instance because of lengthy testing and commercialisation, that needs to be recognised upfront. We can’t leap straight to 6G, terabit FTTx or massive LEO satellite constellations, even if the UK might have an edge in specific components. The new rules need to reflect realistic time horizons – including buffers for delays. That’s especially relevant for things like Massive-MIMO 5G radios.
  • Removing obstacles: The UK’s telcos will continue to need large and medium sized international vendors for the foreseeable future. Ericsson and Nokia will obviously remain central, and we should be looking to encourage Samsung, NEC and Fujitsu in 5G – as well as the continued roles for Mavenir, AirSpan, Parallel Wireless, Commscope, Cisco, Juniper, Microsoft and so on. We need to address why, for instance, Samsung is largely absent from UK MNOs’ networks, despite its profile in Korea and the US. If it is about the need for continued support of 2G/3G and other legacy systems (for instance to support eCall), then we should be considering creative solutions for this. I could even imagine a government-sponsored 2G shared network to support M2M and emergency calls, leaving MNOs to focus on 4G/5G differentiation (and reclaiming spectrum).
  • Global vision: While I can understand why government likes the idea of home-grown UK telecom startups thriving, this vision needs to be tempered with reality. It isn’t realistic to expect UK firms to tackle all aspects of network infrastructure at the scale and expertise needed by major telcos. This doesn’t just mean “heavy iron” macro 5G networks, but also future elements such as fibre transport or hyperscale cloud for next-generation platforms. There won’t be a UK (or European) equivalent to AWS or Azure any time soon, nor a Qualcomm equivalent. If domestic self-sufficiency and ownership was a desire, there would have been obvious questions about recent sales of ip.access and Metaswitch. The diversification review should address areas where the UK should expect to collaborate internationally – as well as its contribution to new standards, for instance on 6G development.
  • Supporting cast: For all the various reasons mentioned above – security, supply resilience, export opportunity and so forth – the “leading actors” of MNOs, semiconductor designers and network hardware/software vendors will need other sets of market players to evolve in tandem. Government is right to be creating testing labs, but should also look at training centres for engineers and installers, university courses, systems integrators, infrastructure financiers, insurance providers and many others. It doesn’t have to (and probably shouldn’t) fund all of these, but it can perhaps advocate for their growth, and help remove barriers if they exist. How many indoor mmWave 5G URLLC vertical specialist engineers - or OpenRAN Massive MIMO maintenance teams - are there in the UK? How can we multiply that by 100x?
  • Flexibility to respond to emergent events: Linked to path-dependence is the concept of protecting “optionality”. I can come up with a range of scenarios under which the world might evolve in surprising directions, both technologically and geopolitically. China might reach a different set of compromises with Joe Biden on network vendors, components and trade. Brexit and new UK trade deals may impact supply chains and telecoms demand in unexpected ways – positive or negative. New cybersecurity vulnerabilities might come to light – or new safeguards developed. Any new policies on diversification should aim to enable new vendors and standards, rather than add constraints such as mandating specific interfaces.
  • Industry verticals & new applications: The UK authorities, like others around the world, seem focused on Industry 4.0, automation, IoT and the potential benefits of greater network-intensity in many sectors. This filters through to the idea of private networks, cloud/edge computing and other adjacent domains. It may also feature high on the telecoms diversification agenda. My view is that this should revolve around a general principle of “advanced connectivity”, rather than specifically relating to 5G and its supply chain. Wi-Fi, fibre, LoRa, Bluetooth and even proprietary network solutions have equally-important roles to play, and as before, neutrality of policy is desirable. The government should consider technology substitution between options, as well as vendor choice within one technology.
  • Awareness of energy & CO2 implications: One of the trade-offs of “abstraction layers” and simplicity/flexibility can sometimes be increased power consumption. “Software-defined X” or “Adaptive Y” can involve lower efficiency than something optimised or hardware-based. The UK should be thinking about a future of networks where everything has a CO2 budget – perhaps with cascading carbon taxes built in. Rather than least-cost routing, we might find networks built around lowest-energy optimisation. I didn't see anything about energy or CO2 in the strategy document.

Overall, as a UK-telecom industry analyst and advisor, I see this as both worthwhile and exciting – and I’m keen to participate in one way or another when possible. I’m certainly intending to check up on how the ongoing pronouncements fit with the principles I’ve outlined here. (I'll also be pondering the international ramifications and linkages).

I think the existing Diversification Strategy makes some good points and has clearly taken inputs from numerous well-placed and knowledgeable sources. However, it’s a bit too focused on 5G, Open RAN and macro networks, rather than the broader realm of “Advanced Connectivity”. I'd like to see more technology neutrality and optionality across the board.

It also blends together multiple issues – cybersecurity, resilience, UK industrial policy, competition, technical philosophy and so on – when they sometimes only have tenuous or debatable links. Interoperability is used as a “glue” to stick together the separate parts. I’d rather see broad top-level goals such as “security” and “optionality” and separate self-consistent analysis for each purpose.

As always, I'll aim to respond to the comments and discussion as much as possible. And please get in touch via email or LinkedIn, if you'd like a deeper dive on any of these areas.

Mobile standards may fragment again, driven by geopolitics

I think we might see a return to the old days of multiple competing mobile standards.

But rather than the US/Europe technical war of 2G/3G over the nuances of GSM & CDMA, this time I see a scenario driven more by US/China geopolitics and ideology, enabled by various technology catalysts.

[This is an extended and more nuanced version of a post of mine on LinkedIn - link, which I edited to fit the 1300chrs limit. It's worth looking at the discussion in the comments there]

The past: how LTE and 5G became global standards

To understand how we got here, and why we might diverge in future, we need to look at the past. Historically, there were two main competing camps for 2G and 3G networks:
  • GSM/UMTS, championed by 3GPP and Europe-centric players such as Ericsson, Nokia and major European operator groups such as Vodafone & Telefonica.
  • CDMA, driven by US companies, especially Qualcomm and Verizon, plus also Sprint, Lucent, Nortel and others, organised via 3GPP2
Back around 2006-7, when 4G was being designed and specified, a number of options were proposed:
  • LTE was the 3GPP's option
  • UMB was the CDMA/3GPP2 approach, leaning heavily on Qualcomm's acquisition of Flarion, which was developing an IEEE 802.20 wireless system.
  • WiMAX, which came from vendors with a Wi-Fi background, notably Intel. That was an IEEE technology too - 802.16.
For various reasons, LTE won, and the others disappeared. (I wrote plenty about this at the time, if you want to go through my archived posts, such as here and here). 

IEEE still technologies dominate in local networks such as Wi-Fi and "personal area networks" such as Bluetooth, but for wide-area mobile, the 3GPP dynasty rules supreme.

But there's a back-story to LTE's success, and its rise as the single global standard for 4G.

In the 3G era, it wasn't just UMTS vs. CDMA2000, but also the Chinese TD-SCDMA standard. (& minor proprietary techs, such as Nextel's & Motorola's iDEN)

TD-SCDMA never gained traction outside China's domestic market, but it helped build the local industry to scale and then evolved into TD-LTE for 4G, which was folded in as part of the global LTE story.

The world's mobile-dedicated spectrum comes in two varieties - FDD (frequency-division duplexing) which uses separate 'paired' bands for uplink and downlink, and TDD (time-division duplexing) which uses a single 'unpaired' band, alternating between up/down slices of time. 2G and 3G were dominated by FDD radios. The inclusion of TD-LTE enabled 4G to access both categories. (WiMAX was TDD-only, a major failing).

The Europe+China combination made 3GPP / LTE unstoppable, especially given the extra scale in terms of both market size and spectrum it enabled. It also cemented Huawei's role as a powerhouse, and partly led to Alcatel's acquisition by Nokia and Nortel's cellular business by Ericsson. Qualcomm's conversion to the LTE cause helped too.  

In parallel to the radio, the 4G cellular core network (EPC) also rose in perceived importance compared to 2G/3G eras, as it allowed MNOs much greater control over data flows. It also allowed vendors easier lock-in.

For the last 11 years, the mobile industry has exploded, partly because of LTE's ubiquity and scale economies, and partly because of the simultaneous rise of the iPhone and Android. It's worth noting that 3GPP's original vision for 3G and 4G didn't see access to the "public Internet" as a core part of the service, although it now dominates usage and value.

In recent years, we have seen the 3GPP "global standard" continue to evolve to 5G, with Huawei, Nokia, Ericsson, Qualcomm dominating the landscape again, plus Samsung and a few others following behind them. At the moment, most 5G is "non-standalone", using the existing 4G cores - and thus again locking-in the established vendors, and the existing powerful core and exclusive national-licence philosophy favouring traditional large MNOs.

However, the 5G vision of many of the industry "old guard" is still centres on the them vs. us approach to network control and "native" (ie telco-delivered) services. There's still the almost-bigoted rhetoric and lobbying about so-called "OTTs" (an obsolete and self-damaging term, in my view), and the attempt to dilute - or at least monitor - the user's desire & ability to access open Internet applications and even connect independently via Wi-Fi.

___________________________________________________________

But now, I see clouds gathering - or new rays of sunshine, depending on your perspective.

I think that geopolitics may undermine the "single global standard" for mobile, along with some conveniently-timed technical evolution paths. This is not a forecast, or even the most likely outcome - but I believe it is solidifying into a much more realistic scenario.

For the later stages of 5G (from Release 17 onwards), and then beyond that with the evolution of 6G, I think the US might be about to diverge from the last decade's consensus.

The Sino-US politics were already stark, even before the COVID19 pandemic added more fuel to the fire. We have already seen massive pressure with regard to Huawei, not just in North America but across Europe and other OECD countries such as Japan and Australia. The US has previously taken action against ZTE as well, and more recently has started even discouraging interconnection with Chinese telcos (link). 

Apparently, the US tech industry is now being pushed/advised to avoid working with China, even on standards development (see this Economist article, although it may be behind a paywall for some - link). That potentially weakens US influence at 3GPP, and could prompt it to seek alternative paths forward. We can expect the US Presidential campaign to focus on this theme as well, over the next 6 months - although both major US political parties have been fairly unified on the ongoing trade disputes with China.

There are also some signs of tougher views in Europe. Even though the UK and EU have allowed continued limited engagement with Huawei, the politics is still hardening, especially in the wake of the virus' trajectory (link).

But this is not just about geopolitics. It is also about technology "philosophy". I see something of a divide here, too. In a way, it's a modern-day version of the Bellheads vs. Netheads battle of the past (link):

  • Control: On one side is a vision of mobile world with strong vendor / MNO / national control, evolved from today's 3GPP & GSMA vision. This has
    • Strong policy control - and eventually network-slicing - delivered from a powerful core network. 
    • Deep reach down into devices, from SIMs to connectivity management, and perhaps surveillance options. 
    • A big focus on optimised & automated infrastructure, which probably favours single-vendor (or at least big-vendor) approaches. 
    • An expectation of exclusive national spectrum licenses, with limited scope for local or enterprise networks which do not also lean on MNOs' services. 
    • There's also a lot of work aimed at reinventing TCP/IP in ways that give telcos more control, as well. 
    • Edge-computing is integrated into the telco domain as much as possible, and delivered as part of a "slice" or MNO service.
  • Openness:The other world vision has a more open / Internet-centric approach. It's more "permissionless" with vendor or even operator lock-ins of any sort being anathema. There's:
    • Less core-network control, favouring local breakout & device-led multiple connections, without the MNO (or government) having a panopticon view of traffic. 
    • An emerging focus on disaggregated & open RAN models (O-RAN, TIP, OpenRAN etc), favouring multivendor- and IT/cloud -centric architectures. 
    • An expectation of Wi-Fi indoors, often owned and controlled by a non-MNO. 
    • Growing availability of more-open spectrum with dynamic / local licenses, as well as traditional exclusive bands as a foundation. 
    • Edge computing is primarily an enabler of telecom networks, not delivered by them - and the expectation is that most will be neutral or independent, in local 3rd-party datacentres/modules or on enterprise premises.
In a way, this is almost a 3GPP vs. IEEE/IETF divide, but just as politics has shifted from a left/right axis to open/closed, perhaps something similar is happening here too.

It's not clear that the wireless world will cleave cleanly along this divide, especially in the near future as 5G is still being deployed. AT&T and Verizon will not be happy relinquishing control-points, either. So today, we have some fairly messy - and maybe unworkable - hybrids. There's lots of talk about opening APIs for enterprises to configure their own 5G slices. We have some grudging approaches to blending cellular and Wi-Fi, and various moves to enable "non-public networks" for enterprise in Release 16 & 17 of the 5G standards. But even that phrasing is awkward and somewhat derisive - as is the term "non-trusted" to describe other access networks.

But the technology forces are clear, even beyond the politics. In the last year or so we have seen:
  • CBRS launching, with dynamic spectrum and a focus on new use-cases and business models, especially enterprise/local networks. It is catalysing a new vendor ecosystem of small cell suppliers, cloud EPCs and specialised SPs and integrators.
  • Huge interest in local/private spectrum and networks in Germany, UK, Japan and elsewhere
  • Rakuten, Dish and other operators validating the vRAN model and working with new US-centric vendors like Altiostar and Mavenir. (Rakuten is, like Softbank, an Internet company diversifying into cellular. Dish isn't "old school" mobile, either, but a satellite TV provider).
  • Huge upswing of presence of IT/cloud players in cellular infrastructure, including acquisitions. IBM/RedHat, Dell/VMware, Microsoft/Affirmed, HPE, Oracle - plus AWS and Google taking various roles from RAN to core, as well as Facebook with TIP and its new stake in Reliance Jio
  • A massive tranche of 6GHz spectrum being made available on an unlicensed basis in the US, primarily for Wi-Fi6E, but also maybe 5G variants in future as well. This has further killed off the (already implausible) idea that cellular-based LANs might edge out Wi-Fi
  • Fragmentation of the EPC / 5G Core marketplace, with low-cost / cloud-based / programmable / "light" variants that look like a normal piece of the IT stack, rather than arcane telco wizardry. (I wonder if we'll see "core-optional" mobile networks - but that's for another post).
  • More interest in mmWave in the US and South Korea, including for indoor use.
  • FCC and the White House have taken a close interest in 5G and next-gen wireless, and seem keen to foster a local technology ecosystem for mobile (link)
  • Innovation in satellite constellations such as SpaceX's Starlink
  • Plenty of other big US-centric technology players watching closely, such as Cisco, Juniper and of course Apple.
  • (I know there's also various moves around evolving TCP/IP, but I haven't had a chance to get my head around them yet).
We might still see 5.5G and 6G world emerge as an elegant hyper-converged version of these two philosophies. And we'll certainly see firms such as Ericsson and Huawei try to continue the 3GPP/control vision, while also exploring the opportunities and tools from the other side. Neither seems especially happy with the rise of local/private spectrum or pure-play enterprise and neutral-host providers. It's easier to sell direct to 100s of MNOs, than 10000s of enterprises via a myriad of new channels and integrators.
 
I'm also interested to see what happens with ownership of Nokia (which seems a bit more open to the new realities) given its financial woes - and also how the European governments and regulators act. Is Europe a bridge between the two worlds, or does it fall in the gap? 

In many ways, I see the EU model lean more towards MNO control, with governments happier to focus regulation on competition at commercial levels, rather than technical - it tends to push harmonisation heavily, as a consequence of its previous success with GSM which catalysed the whole sector. There is more wiggle-room around enterprise and local spectrum licensing, given the strong lobbies for manufacturing and other industrial sectors., plus more emphasis on privacy.

I can imagine Japan aligning more with the US vision, but South Korea in a similar position to Europe. A year ago, Samsung was the obvious beneficiary of Huawei's problems. Now, it's probably the OpenRAN ecosystem that's the effective #3 choice.

At the moment, I'd rate the chances of a more-serious and clearer split at 30% and rising. It won't happen overnight - I think that Release 17 is probably the trigger-point. By the time we get to 2030 and 6G though, I wouldn't be surprised to see a revival of something that looks like 3GPP2, or perhaps (whisper it, as many will cringe) WiMAX2. At the very least, it will be more Internet-flavoured.

If the "old guard" vendors and their institutional peers within 3GPP, GSMA, ETSI etc. want to avoid this bifurcation, they are going to have to make some difficult decisions, and soon. Otherwise the potential to be disrupted from adjacency will grow. They need to be genuinely open, and start loosening the vision of pure "end-to-end control", and embracing imperfect, inelegant pragmatism about network design, operation and ownership. Exactly how that fits with the worsening geopolitical landscape is a problem I'll leave for the diplomats and spin-doctors.

Quick thoughts on MWC from afar

I'm not in Barcelona this week.

I stopped going to MWC a few years ago, when the hassle and costs involved started outweighing the benefits. One year I had 400 requests for meetings, and it took me a solid 2 weeks of email just to sort my diary. No more - I prefer smaller events, which have the added benefit of fewer "messages" being hammered into my skull by stressed marketing execs and their PR/AR minders.

But I am watching from afar, scanning Twitter and a few webcasts for nuggets of insight, from the comfort of my sofa, bed or local artisan coffee place.


A couple of quick observations so far:
  • The most intriguing announcement is the Cisco/Ericsson blending of VoLTE and Cisco's Spark collaboration and messaging app (link). Although the PR is carrier-focused and around selling UCaaS, I suspect the real story is yet to come. Both companies also have close relationships with Apple and IBM. And I suspect that a future enterprise-centric solution could combine private (or virtual-private) mobile networks, optimised iPhone/iPad experience, maybe eSIM, Siri, Watson integration and more. Let's see if there's any different messaging, or more detail, at Enterprise Connect next month, the big UC/UCaaS shindig in Orlando. I'll be there, unlike MWC, as it gets the signal/noise ratio right. [Sidenote: if anyone at Ericsson or Cisco is now thinking "hmm, sounds interesting.... why haven't we thought of that?" then get in touch with me!]
  • Nokia's reinvention continues. On its analyst/press webcast yesterday, it made a big deal about verticals and enterprise-related activities too. Utilities, transport, public sector and "webscale" companies were namechecked, including (again) private cellular either standalone or in partnership with classical MNOs. It also highlighted optical and IP networks (which came with the ALU acquisition) which was an interesting choice for a mobile event. Props to CEO Rajeev Suri for using "Webscale" instead of the pejorative "OTT": much more mature and inclusive language. 
  • There's an awful of of 5G-washing going on, unsurprisingly, with plenty of references to its supposedly world-changing abilities. Governments and policymakers have all swallowed the 5G spin, without realising it's mostly just a pitch for more spectrum. Yet the GSMA head Mats Granryd talked in his keynote about 1.1 billion users in 2025. Given half of those (or more) are likely to be smartphones, that suggests that maybe 500m, at most, will be 5G IoT devices. Which, depending on your preferred overhyped forecast number, implies about 1-4% of the total IoT universe in 2025 - hardly the most indispensable enabler of the overall automated society of the future, nor an indicator that a spectrum monoculture policy is desirable. Doesn't suggest billions in new value from network-slicing capabilities, either. In a nutshell, 5G is important, but it's not the gamechanger many assert. Use the hashtag #5Gwash to call people out on it.
  • The most-discussed new handset is HMD Global's new take on the classic Nokia 3310. As well as its retro looks, it sports a month-long battery, the Snake game, and a whole two (count 'em!) generations of cellular technology. That's right, it's a good-ole 2G GSM, calls+SMS device. Plus, it comes in a dual-SIM version. That's proper plastic SIMs, naturally, not this newfangled eSIM stuff. Sounds like a great backup device for 2-factor authentication when your main phone breaks or gets stolen.  
  • GSMA published an eBook on "Messaging as a Platform" (link), tying its MaaP vision to RCS. There's a lot of generic stuff about chatbots, AI and "conversational commerce" in there, without explaining how it relates to a useless messaging service which isn't even a successful product, nor has any form of unifed API. Unless, as I suspect, it's aimed at making MNOs the distribution channel for Google's chat interface, Assistant and voice-recognition tools. Maybe there's a Google API / PaaS play to look forward to?  As I wrote last week, operators should ignore RCS and So-Called Advanced Messaging (yes, I like the acronym) and do more-relevant things instead. The same applies to contact-centre and multi-channel vendors: there are plenty of more-urgent things to look at. The GSMA's continued use of a Twitter SnapChat avatar points to the fact that platform status is earned not just imposed.
  • The "official" announcement that Deutsche Telekom's immmr VoIP/messaging spin-off is using GenBand's Kandy cPaaS is interesting (link), although it was talked about informally last year at TADSummit (link). Looks like it's Internet/WebRTC-based and very much a good example of "post-IMS" mobile communications, with iOS and Android apps as well as browser access. No RCS nonsense visible, although I can imagine that DT's network-fundamentalist wing might have something to say about in future.
More MWC de-spinning if I get a chance over the next couple of days.

Cisco and Ericsson: Will the Enterprise move to Private IMS & Cellular?



A lot has been written already about the ramifications of the wide-ranging Cisco / Ericsson deal. Most industry analysts and other observers have already come up with assessments of areas of impact, effects on other vendors (eg Juniper), and the implications for various telco-network technologies such as SDN / NFV.

A fair amount of output has been interpreting the “official line” from the two vendors’ press releases and briefings, which have been a little thin on exact details of how the collaboration will evolve. Light Reading has collated a good set of opinions here, for example.

So I'm going to speculate a little - and consider what is not being mentioned so far. This is a blog post about "what might happen" - there's a lot of variables, complexity and execution risk. Caveat lector.


The story so far: Selling & integrating IP gear & cloud platforms for telcos

Looking around the web, it seems that there’s a roughly 80/20 split between analysis of telco-area implications vs. enterprise. This is unsurprising, given the early focus areas announced - the Ericsson CEO says “Initially the partnership will focus on SPs” in the release. Also, the bulk of observers who cover both companies are strongly focused on SP networks.

But my sense is that a few angles have been overlooked, especially about enterprise. I'll highlight a line in the slide-deck the companies used: "Creating leadership to address converging telco and enterprise domains".

The assumption among most people seems to be that "convergence" here is viewed only in one direction. It's assumed to mean an increasing role for telcos in managing enterprise networks and communications functions. And yes, a lot is about combined sales to/through telcos. Cisco gets to sell IP gear via Ericsson's huge SP-focused services and integration teams, and better integrate its products with the OSS/BSS domain. Going forward, the partnership can allow better network/service coverage in corporate offices, or enable assorted business cloud and IoT offers to be provided by telecom operators.

Yet "convergence" occurs when two trends meet in the middle. There's another side here: enterprises starting to adopt or manage telco-type networks and capabilities. 


But what's in it for the enterprise?

So what does Ericsson have, that Cisco can sell / add value to via its enterprise channels? And what new combined products might come from both firms' R&D labs that could be of interest beyond the reach of telcos, sold directly into the corporate domain?

I have sensed for a while that Ericsson wanted more direct business with enterprises and governments - it recognises that its addressable market for telco capex/opex (whether hardware or managed services) is limited by telcos' own growth difficulties, as well as competition from Huawei, wariness of IT players like Oracle, and the move to software-based (and sometimes open-source) infrastructure. 

It was no coincidence that last year's analyst conference in Stockholm was held partly in Volvo's premises. Or in another area I watch closely, that its WebRTC activities have involved things like online banking (see here) without a mention of telcos at all.

It's not just Ericsson. We've also seen other telecom vendors pitch to goverments, city authorities, utilities, transportation companies and so forth. There are private cellular networks intended for railways and mining operations, to e-commerce and cloud propositions, or re-use of billing/charging for utilities and smart city initiatives. Quite a few vendors also sell to "non-telco SPs", ranging from call-centre providers to (ssshhhhh!!!) big Internet firms, as well as amenity-type public WiFi implementors.

So - the question is what the joint Cisco/Ericsson initiatives might be for enterprise. The briefing deck gives some rather vague lines like "comprehensive systems integration, managed services and technical support for enterprises" as well as "cloud and data-centres" which potentially cover a multitude of sins.

Another interesting line is "Networks of the future require new design principles to ensure agility, autonomy, and security". The interesting word there is "autonomy" which means "the right or condition of self-government." For whom, exactly? For telcos, it could mean the freedom to choose between multiple vendors' platform ad 3rd-party VNFs - but I'm not convinced that's a story that Cisco and Ericsson really buy into.

My sense is that actually - and this is probably a medium-term thing rather than immediate - there are three aspects:
  • Distributed enterprise cloud platforms. This should be unsurprising given both references in the announcement, and Cisco's data-centre expertise. Ericsson SDN/NFV work could fit in here, although it's not the main focus of this post.
  • Private wireless. This includes both WiFi and potentially private cellular networks, indoor, on campuses, and perhaps for large areas or governmental applications.
  • Comms, Collaboration & Private IMS. Both partners have a lot of history in voice, messaging and video communications, not just in telcos but also deployed by businesses. Ericsson used to make PBXs but sold to Aastra in 2008. While UC, cloud and collaboration is impacting the traditional PBX/IP-PBX market, that doesn't mean that enterprises want everything delivered "as a service". Cisco & Ericsson can help both telcos' UCaaS propositions - but also help corporations take back control in-house.
It should be noted that the last two points are unlikely to be especially popular with the telecom service provider community, and would thus not be the focus of the initial SP-friendly announcement.


Private Wireless

Together, Cisco and Ericsson have a decent chance of “fixing” indoor mobile coverage, capacity and control for large enterprises. Both have WiFi assets and also small-cell exposure (Cisco especially via its SpiderCloud partnership), but the kicker here is Cisco’s footprint and understanding of the enterprise fixed LAN and security domain. 

There are two angles here:
  • Helping mobile operators "reach" deeper into enterprises to allow better in-building cellular coverage, WiFi offload/voice and (in the GSMA's dreams) run corporate wireless data connectivity as a fully-managed service. Print-over-4G....
  • Allow enterprises to better manage and run their own mobile infrastructure, most obviously in unlicenced spectrum. This could extend beyond traditional WiFi towards allowing private management of LPWAN (low power networks) for IoT, rather than using Opex-centric services like SigFox's.
Historically, one of the main problems for enterprise pico/femtocells, or use of corporate WiFi for offload and carrier VoIP, has been how these coexist with the corporate-run firewalls and in-house network management and prioritisation. Normally, telco visibility/control ends “outside” a demarcation point. Most enterprises will view outbound VPN tunnels from small cells, or external control of devices on the LAN, as a security risk. Telcos, in turn, are hesitant to offer service guarantees where they have limited ability to measure or manage performance – and will also see security issues. 

There are also various issues with security, privacy and legal liability when using a 3rd-party cloud platform for identity, data processing or storage.

There is a chance here for Cisco and Ericsson to create solutions to all these areas. The short-term headlines will probably be around better in-building cellular (competing with DAS and, implicitly, SpiderCloud) and IMS WiFi-voice support, but the longer-term vision will perhaps include:
  • Carrier-managed enterprise WiFi, perhaps in neutral-host mode to support multiple cellular operators' subscribers on the same network
  • Private corporate-run LTE-U networks, maybe using Qualcomm's MuLTEfire or something similar, for indoor or campus usage
  • Private IoT networks using both unlicenced and licenced spectrum, linked into corporate IT and communications systems directly, rather than via a service provider
  • Licenced-band cellular for non-telco organisations with access to cellular spectrum (eg public safety networks, rail/transport systems, maybe smart cities or big oil/mining companies in remote areas)
  • (Perhaps, depending on regulation) ways to enable "corporate MVNOs" 

This is all pretty speculative - and it may be that some of these concepts are a long way off, and perhaps not even fully-considered by Ericsson and Cisco themselves. (Get in touch if you'd like me to run a brainstorm workshop, guys!)
 
 
Comms, Collaboration & Private IMS

Absent from the announcement was any clear reference to communications: UC/UCaaS, IMS, VoLTE, WebEx, Spark, WebRTC and so forth are, to me, elephants in the room.
 
Predictable things we'll likely see include various Cisco-to-Ericsson moves, around UCaaS and WebEX linked to Ericsson's IMS. But I think that's only part of the story that will emerge.
 
Let's go back to that term "autonomy" from above. 
 
It's easier to get seduced by the idea that enterprises (and small businesses) want to get rid of their old on-premise phone systems, recognise their employees are mobile-first and BYOD-minded, and shift to some form of UCaaS platform linked to a telco network and number. Yet on the ground, plenty of enterprises either want to keep control of their own communications system, or are using 3rd-party Internet-based tools like Slack, rather than an SP's integrated proposition. 
 
I don't think that's going to change - many businesses prefer to keep hold of their own "phone" system, especially as it becomes part of their messaging or contact-centre or contextual-comms platform. That doesn't mean it has to be a lump of tin, or a proprietary IP-PBX platform for call control - it could be in the cloud, or using standardised software elements. It just doesn't have to be a "per-seat per-month" cost model. 
 
A rather surprising term I’ve heard a few times recently – mostly from folk in the IT/cloud industry – is “enterprise IMS”. It’s not an industry-standard term, but basically, it means that some large businesses want to deploy their own internal IMS-type infrastructures as communications/service platforms. These might be owned outright, managed on-site by third parties, or delivered from multi-tenant clouds in the same fashion as UCaaS today. But I think this area is one of the likely mid-term outcomes of the Ericsson / Cisco deal, if the concept comes to fruition.

Remember - PBX stood for Private Branch Exchange. We should not be surprised if the IP and Mobile equivalent turns out to be the enterprise-owned PIMS, not a "mobile PBX" run as a service in a telco network. 
 
It’s being catalysed by a few things:
  • Mobile and BYOD: many employees are using mobile devices for most of their business communications. But most UC/smartphone implementations are still a bit clunky, with varying UIs depending on device and especially iOS vs. Android. Having an enterprise-run IMS (and voice application) would potentially allow the CIO to regain control of the “native dialler” on a phone, especially when connected in-building. There are open questions about numbering, but they may be tractable.
  • Cloud / Open-Source IMS: A few years ago, the idea of an enterprise owning an IMS would have been ludicrous, given the costs involved. But now, with virtualisation, cost pressures by telcos wanting cheap VoLTE, the emergence of open-source options like Metaswitch Clearwater, it is becoming much more downward-scalable. PIMS is starting to look like a cost-effective option.
  • Applications: Currently pretty much the only useful IMS application is straightforward VoIP/VoLTE phone calls. That isn't enterprise-optimised - it lacks the typical PBX-type functions that are needed. There aren't really telco-IMS contact centre apps, and nonsense like RCS certainly doesn't address enterprise messaging. Having a PIMS/WebEx/Spark combination would be much more interesting. Potentially it could also be run as an operator-hosted service, but I think the real value is where it is owned outright.
  • Middleware & APIs: Where this starts getting really interesting is in the creation of integrated apps blending a corporate comms platform, with corporate IT systems. Hooking into existing software platforms for sales or field automation, line of business and so forth. Potentially this is where a combination of a Cisco/Ericsson PIMS + Tropo starts looking interest. (Sidenote: unlike GenBand with Kandy, Ericsson lacks a WebRTC PaaS)

There’s a few other angles that play in here too. Most notably Cisco's earlier partnership with Apple, which I think many have underestimated. It is likely to optimise iPhones & iPads for use with Cisco's security, WiFi and collaboration tools. I can envisage a situation where companies ditch their old desk-phones for Apple i-Devices, either BYOD or company-issued, linked to Cisco communications apps running via an Ericsson PIMS, with outbound SIP/IMS trunks if needed. Potentially this could work with virtual numbers as well - not just for the US where fixed/mobile numbers are indistinguishable, but the rest of the world where mobile numbers are from separate defined ranges. 

Having a corporate-issued mobile number, anchored in a PIMS, would make a lot of difference - ability to use SMS, better fit with assorted apps that use mobile numbers for identity or authentication, porting in/out, maybe even assigning mobile numbers to IoT objects. There's a lot of variables here, and the rules will likely vary by country.

And for a long-range view, consider Apple’s work on virtual / eSIMs added in to this. Telcos might not like the idea of virtual SIMs in phones – but an enterprise, running its own IMS, its own WiFi network, and perhaps having access to LTE-U and maybe even its own mobile network code – may not be so squeamish. There are various types and styles of enterprise MNO and MVNO that can be envisaged here, depending on local regulation, willingness of local operators to wholesale or allow roaming, or even share spectrum. I can even imagine an “enterprise MNO” being run as a managed service by Ericsson.

Who would be impacted by this? Microsoft is at the top of the list, and also the traditional mobile operators’ enterprise units which still make good margins on corporate mobile subscriptions. It also sits against the emerging Google/Android/Telcos/BroadSoft/Switch enterprise ecosystem. Avaya is left looking a bit lonely here (although it also works with Google), as are the smaller UC players like Shoretel. It possibly even makes the bizarre Mitel/Mavenir acquisition look more sensible in hindsight, although that’s still pretty baffling.

The interesting question is whether Cisco and Ericsson have actually looked closely at what they might be catalysing – or whether they are themselves likely to be as surprised by the direction of travel. Obviously there are lots of questions about execution that come first, but if things go well, there could be a game-changer afoot.

(None of this is entirely new as a concept. About 10 years ago, I did consulting for a company called Zynetix (later bought by Sonus Networks) that sold enterprise-grade cellular-core MSCs that linked to PBXs. They could allow businesses to run private mobile networks, especially when linked to pico/femtocells running in “guard band” spectrum in the UK. However it was perhaps ahead of its time, hampered by some of the practicalities such as spectrum/radio limitations, needing clunky user-experience hacks like manually selecting different networks).



Conclusion

The bottom line is this: the notion that ALL enterprises will outsource the bulk of their internal networking or communications functions, especially to telecoms service providers, is a comforting myth. Yes, some will - hence the rise of UCaaS for mid-market businesses, and telco-managed WiFi in places like airports or sports stadia.

But that is only part of the story.  


Some enterprises will want to continue managing networks and communications in-house (whether on-premise or in a private cloud). This will ideally expand to include aspects of mobile networks/services where possible. Expect PIMS, better WiFi, PLWPAN and maybe PLTE and PMVNO models. Others will want to outsource these functions to IT-type service providers like IBM, rather than telcos.

Potentially, Cisco+Ericsson (with a side-order of Apple) can facilitate all these different paths to the user. This might not be popular among traditional telcos, but in my view the trend is inevitable. Enterprises will re-assert their control (and sometimes ownership) of wireless/mobile networks and communications platforms, especially as they become more-integrated with business processes and applications. 

There's a lot of reasons why this partnership might fail to bear fruit. But a lack of potential exciting and disruptive opportunities in enterprise isn't one of them.
