Telcos: Stop Thinking You're Always the Leading Actor

Hubris: "an extreme and unreasonable feeling of pride and confidence in yourself"

I've followed developments in the telecoms industry for over 25 years. I've seen positives (eg broadband, SMS, LTE) and negatives (UMA, RCS) as well as a shifting landscape of regulation, the rise of the Internet, and multiple generations of network technology and services infrastructure.

Undoubtedly, both fixed and mobile networks have added massively to economies, society and our current way of life. It's understandable that network operators - and their vendors and governments - feel proud of their legacy and want to perpetuate it.

Yet it's possible to take this too far. Even beyond obviously-silly pronouncements such as "5G is as important as electricity", there remains a constant thread among the telecoms industry that it is absolutely central to all future developments, and that the network's finely-engineered QoS mechanisms are the wellspring of technology-derived value, as well as pivotal to future GDP and world happiness.

But while self-belief and aspiration is helpful, arrogance and self-delusion is not.

 



Starring role, or supporting cast?

There is an assumption that the (public, traditional) network is always the leading actor in any movie about Industry 4.0, IoT, smart homes, AI, pandemic recovery & the "new normal", combating climate change, or creating new modes of communications and entertainment like AR/VR.

And yet in reality, the telecom network - especially public 5G - is often going to be a supporting actor. Or perhaps just have a walk-on role, or be relegated to an extra who gets dubbed in a different language.

You can almost imagine a C-list celebrity arriving at a busy party and shouting: "Guys, guys! Listen up! You can get rid of all your old stuff, all your Internet apps, all your legacy Industry 3.0 gear... just use our new [Technology X] instead, and we'll offer it all with a nice monthly per-GB subscription. You can even buy a slice!"

Heads swivel. Eyes roll. People refill their glasses & continue their conversations.

A bit more realism and humility is required. Telecoms isn't always the star of the show, and neither does it write the screenplay for the rest of the infrastructure or solution.

That doesn't mean it lacks value, or has a limited opportunity - but that it has to play nicely alongside others... and accept that the director and producer have other priorities to focus on - and a wide choice of alternatives to cast in the same roles.

Leaving the acting analogy aside, it's also important to understand that the nature of the word "telco" is itself changing. Looking out to 2030, the "telco of the future" isn't like todays - there won't just be 3-4 national MNOs and a handful of converged/fibre/fixed-line operators. There will be a vast diversity of service provider types and private/community networks. I've written before about the "new telcos" and this is a critical aspect for traditional ("legacy"?) operators to understand and even embrace.

This isn't just 5G-related

It's tempting to just see this as a problem with how 5G is being positioned and hyped. But while I discuss that below, it's far from being unique. This attitude has been around for years, and pervades the entire industry. Some examples of this mindset include:

  • Telcos consistently assume that "voice" means the same as "telephony", since they only do the latter. Telephony is just one voice application of hundreds - and a 140yr-old clunky and poorly-optimised one at that. This is why telcos don't have a foothold in voice assistants, critical comms, gaming voice, podcasts and so on - and get out-competed by cloud players for UCaaS and cPaaS. (For more: see my upcoming workshop series on the future of Realtime Comms, Voice & Video, starting May 19th)
  • 20 years ago, 3G networks were pitched as platforms for telco-created and telco-delivered videoconferencing, games, "value-added services" (ringtones, basically) and much more inside "walled gardens". The killer app was, in fact, plain vanilla Internet access - despite early dataplans trying to restrict the use of VoIP and IM.
  • Some 1980s & '90s telcos saw themselves as central to enterprises' telephony systems and pitched "Centrex" services - basically a precursor to today's cloud-based UCaaS. Most businesses decided that running their own PBXs was a better option - it fit with their internal organisation and operations much better.
  • Telcos' MEC edge-compute was supposed to take centre-stage against hyperscale cloud providers. Instead, MEC's main use is to host internal NFV or vRAN functions that run the network itself. Or enable some hyperscalers' own edge platforms on a wholesale basis, where they don't have other options. Meanwhile, edge-compute evolves in many other (non-telco) domains much faster, including on-device / gateway, or linked to non-3GPP technologies such as Wi-Fi and fibre.
  • RCS was initially supposed to replace all Internet-based messaging apps. Then its believers pivoted to pitch it as a universal B2C tool for mobile customer interactions. In reality, it's (at best) just another slow-moving messaging app with few users and no loyalty, or special features. It turns out to be channel #17 for consumers dealing with companies that don't merit downloading a proper app or which have a lousy website. RBM's best hope is for things like tickets from that 3rd-tier airline you're forced to use to get to an obscure airport, or ordering a new recycling bin from the local council's chatbot. It's competing with the browser, not apps or Internet messaging.
  • MNOs' public 5G with network-slicing was supposed to replace all the cumbersome enterprise network gear such as ethernet and Wi-Fi. There are still visions within obscure 3GPP work-groups about "5G LANs" and I still read and hear nonsense from the cellular industry about it replacing Wi-Fi at scale....
  • ... or alternatively, the new story is that the 5G core is going to be the centrepiece of all telecoms and networking - it'll control Wi-Fi, fixed broadband, satellite connectivity etc. on operators' terms and policies, of course. (See the Broadband Forum's rather Machiavellian efforts here - led unsurprisingly by behemoths like Verizon & Deutsche Telekom that want the core network as a "control point" all the way to end-devices in the home). Yes, maybe Wi-Fi can easily just slot into 5G's shiny new cloud-native core - but in reality, 99% of Wi-Fi has nothing to do with cellular networks, offload, or non-trusted / non-3GPP access
  • As I mentioned recently, the telecom industry tries to take 100% of the (carbon) credit for new technologies reducing energy consumption or emissions.

The ridiculous and judgmental term "OTT" exemplifies this - creating a them-and-us fallacy of "web" companies using "our" pipes. Never mind the fact those technology companies build their own infrastructure, and invest billions in R&D for everything from AI to chip design. Or that all telcos themselves deploy "OTT" apps, websites and Internet-delivered functions.

To use a more sociological phrasing, many network operators still have a "sense of entitlement". They feel that they should be running everything from voice and video communications to networked entertainment, smart homes, or B2B commerce and industrial automation.

This attitude extends into public policy, and discussions on topics like spectrum, where there is a sense of exerting "license privilege". There is often an attempt to exert control before earning it. This is different to (say) Apple's control of its AppStore.

(*Sidenote [And apologies to my clients if this stings!]:if you work in telecoms & talk casually about "OTTs" for anything other than TV streaming, you should be fired, and so should your boss. It's not only wrong, it's flat-out ignorant and damaging. It indicates gross incompetence. It's not quite a "hate crime" but it is a them-and-us divisive term for a distinction that simply does not exist).

Actions have consequences

There are several reasons why this problem is more than just "attitude" or normal marketing-related hyperbole. It directly translates to business successes and failures.

  • Many telco technologies don't just benefit from n-squared network effects, but depend on them. They degrade "non-gracefully" if they're not ubiquitous - which means they need to be adopted by other telcos at the same time. Messaging is a good example - at 50% uptake, across 50% of operators that implement a new standard, there's a high % chance that two people on different networks won't be able to communicate, especially internationally. There's no focus on saturating small niches, or communities of interest, then expanding over time.
  • Telcos spend so much time envisioning themselves as "platforms" that they fail to realise that pretty much every tech platform evolves from a great (and widely-used/loved) product. Google indexed the web & created a great seach function, before it started selling ads. Apple sold the iPhone for a while before launching the AppStore. It also had a loyal base of iPod users who wanted a music-phone, too. Amazon sold books before it launched AWS. All of them had platforms in mind earlier... but had to create a product before tuning the way the platform needed to behave for customers / developers.
  • The telecom industry always assumes that it will be a "net exporter" (or even pure exporter) of capabilities and APIs. It expects it will sell more "exposed functions" than it buys. It assumes a role at the top of the value chain, rather than the middle. This is starting to change now with the recognition of the role of buying public cloud services for virtualisation, but prior to that it just relied on Google Maps for "find the closest store", or credit-checking agencies for new subscriptions. Almost all successful tech businesses these days are more like trading hubs, importing AND exporting functions, APIs and data. The assumption that telcos will always be the OrchestratORS rather than OrchestratED is leading to an unrealistic world-view and poor decisions.
  • Conversations with regulators and governments try to amplify the supposed "special" status and reinforce the spurious divide with new telcos or Internet/tech firms. "We don't want to be dumb pipes, so please tax & regulate the clever people, because we can't compete". This might seem smart - and perhaps gets better access to new funds for rural coverage or pandemic recovery - but it also hampers and limits future options, for instance around international mergers and expansion. Domestic champions find it hard to live dual lives as global heroes.

What needs to change?

There needs to be a frank, honest discussion about "Telcos' place in the world", which works out how to transition from a world of a few licensed network operators per country, to one in which the landscape is much more complex and nuanced.

  • Position the term "telco" as a broader church & consider the needs/roles of the wider group. MNOs and fixed telcos are important, but not alone here. TowerCo's are telcos. Neutral Hosts are telcos. WISPs are telcos. MVNOs are telcos. Governments can act as telcos. Community networks are telcos. Consider them peers. Insist that GSMA, CTIA, ETNO and others treat all telcos equally and offer membership (and governance) on reasonable terms.
  • Don't push back against governments trying to enable new forms of competition and new entrants. Instead, exploit them. Offer reference designs for Open RAN internationally (see Rakuten). Launch Private 5G services in new countries with local spectrum (Verizon is doing this). Run MVNOs in other countries (Turkcell, China Mobile etc).
  • Internet, IT and industrial automation (OT) companies need to be seen as equal and equivalent peers too. Amazon, Microsoft, Google, Siemens, Honeywell, IBM, HPE, Tech Mahindra, NTT Data & many others will often own the customer relationship. Sometimes telecoms fits into their frameworks, and sometimes theirs' fits into telcos. Maybe there are roles for gatekeepers, but only where there is enough competition.
  • Telecom standards need to become much more "loosely coupled". The traditional insistence that a 5G radio needs a 5G core and IMS/VONR telephony needs to stop. 3GPP standards and interfaces should be mix-and-match. Rather than trying to push complex core networks into fixed broadband architectures, the industry should instead make core-optional lightweight variants of 5G RANs, or expose interfaces that make them controllable by enterprise IT, or a Wi-Fi platform.
  • Offer both complete solutions and sub-component services. Don't assume primacy - sell what customers want. Maybe enterprises want their own Private 5G, but would happily use telcos to do the installation and maintenance, or to enable roaming or as a provider of eSIM-aaS
  • Use 3rd-party infrastructure and connectivity where it makes sense - for instance on neutral host networks. Attempt to automate onboarding, and remove friction wherever possible. Accept national roaming if it means your customers get better access in remote places, or indoors.
  • Work out better metrics to measure the business & communicate these to investors and regulators. See this article on what metrics are especially poor.
  • Understand software and app developers' mindsets. They don't want to pay for "premium QoS" on a thousand networks. They want warning of congestion, and how to adjust their apps' demands - when/how to use on-device compute vs. cloud, which codecs and compression, and so on.
  • Stop thinking that phone calls (and worse, video calls) are perfect manifestations of communications, with just an upgrade every 10 years from circuit to VoLTE to VoNR. Why doesn't the dialler app get updated once a month with new features, or give the user more controls?
  • Look at alternatives to subscription business models. Why not an insurance-style annual premium? Or "dark spectrum" just like "dark fibre"? Or 100 others?
  • Invent more stuff. Spend money on R&D rather than sports TV rights. Much of the current angst comes from competing against tech firms that actually create products and services that people want to buy/use.
  • Have a much clearer policy and stance on buying/selling technology and services. Make using platforms effectively seem as important as creating platforms. This is starting to happen with cloud and Open RAN, but it's very slow.

It has been interesting to see that the most interesting - and lauded - new telcos have come from different backgrounds, and have different attitudes. Rakuten is a cloud/eCommerce company first and foremost. Dish started as a satellite TV provider. Jio's parent Reliance Industries is a broad conglomerate. Although not a new company, South Korea's SKT is part of the SK Group, which also has a broad set of non-telco assets.

To be fair, one area where telcos are taking a more hybrid position is around physical assets. Some are operators/co-owners of shared networks, some spin-out tower businesses, some sell dark fibre and some buy - or both in different places. Some use public colocation and data-centres, while others are looking at local offices as possible edge compute sites.

Conclusions

This undoubtedly comes across as a bit of a rant (and not for the first time...) but it's coming from a position of frustration. I've seen the same issues play out for years - and at the core is this attitude of entitlement that I mention above.

It's totally counterproductive, even if the inertia - and sense of history - is understandable.

Everyone wants to be the star, especially if they've been the lead actor for decades. But sometimes, the role just involves a couple of scenes. And often, it's just the cameo roles - if played well - that get the headlines after all.

Verticals 5G: It's more than just MNOs vs. Private Networks, there's a whole new universe of other service providers too

For the last few years, I've written and spoken extensively about 4G or 5G cellular networks optimised for enterprises, whether that's for a factory, a port, an electricity grid - or even just a medium-sized office building. Recent trends confirm the acceleration of this model.

  • CBRS in the US is growing rapidly, including for local and industrial/utility uses
  • Localised 4G/5G spectrum is now available in UK, Germany, Netherlands, France, Japan and elsewhere, with many new countries examining the options
  • Many campus/dedicated network strategies by traditional mobile operators (MNOs)
  • Assorted testbeds and trials sponsored by governments, groups like 5G ACIA etc.
  • Growing intersections with Open RAN and neutral host models

An inflection point has now been reached.

Enterprise/local cellular is happening, finally

It's been a long time coming. In fact, I've been following the broad concept of enterprise cellular since about 2001, when I first met with a small cell vendor, called ip.access. Around 2005-2009 there was a lot of excitement about local 2G/3G networks, with the UK and Netherlands releasing thin slices of suitable spectrum. A number of organisations deployed networks, although it never hit the massmarket, for various reasons.

Now, however, private 4G and 5G is becoming "real". There's a critical mass of enterprises that are seriously interested, as this intersects with ongoing trends around IoT deployment, workforce automation, smart factory / city / building / etc concepts, and the availability of localised spectrum and cloud-based elements like network cores. It's still not easy, but the ingredients are much more accessible and easier to "cook".

A binary choice of MNOs vs enterprise?

But throughout this whole story we've had an underlying narrative of a two-way choice:

  • Enterprises can obtain private / on-premise cellular networks from major MNOs as a service, perhaps with dedicated coverage plus a "slice" of the main macro network and core functions.
  • Enterprises can build their own cellular networks, in the same way they build Wi-Fi or wired ethernet LANs today, or operate their wider private mobile radio (PMR) system.

This is a "false binary". A fallacy that there's only two options. Black & white. Night & day.

In reality, there's a whole host of shades-of-grey - or perhaps a better analogy, multi-coloured dawns and sunsets.

Not just MNOs

There is a lengthening cast-list of other types of service provider that can build, run and sell 4G and 5G networks to enterprises or "verticals" (the quaint & rather parochial term that classical telcos use to describe the other 97% of the economy).

An incomplete list of non-traditional MNOs targeting private mobile networks includes:

  • Fixed and cable operators, especially those which have traditionally had large enterprise customer bases for broadband, VPNs, PBXs / UC, managed Wi-Fi etc.
  • MVNOs wanting to deploy some of their own radio infrastructure to "offload" traffic from their usual host provider in select locations.
  • TowerCo's moving up the value chain into private or neutral networks (for instance, Cellnex and Digital Colony / Freshwave)
  • IT services firms affiliated to specific enterprises (for example, HubOne, the IT subsidiary of the company running Paris's airports)
  • Industrial automation suppliers acting as "industrial mobile operators" on behalf of customers (maybe a robot or crane supplier running/owning a local 5G network for a manufacturer or port, as an integral part of their systems)
  • Utility companies running private 4G/5G and providing critical communications to other utilities and sectors (for instance Southern Linc in the US), or perhaps acting as a neutral host, such as a client in Asia that I've advised.
  • Dedicated MNOs for particular industries, such as oil & gas, often in specific regions
  • Municipalities and local authorities deploying networks for internal use, citizen services or as public neutral-host networks for MNOs. The Liverpool 5G testbed in the UK is a good example, while Sunderland's authority is looking at becoming an NHN.
  • Railway companies either for neutral-host along tracks, or acting as FWA service providers in their own right, to nearby homes and businesses.
  • Specialist IoT connectivity providers, perhaps focusing on LPWAN connectivity, such as Puloli in the US.
  • FWA / WISP networks shifting to 4G/5G and targetting enterprises (eg for agricultural IoT)
  • Overseas MNOs without national spectrum in a market, but which want to service multinational enterprise clients' sites and offices. Verizon is looking at private cellular in the UK, for instance - and it wouldn't surprise me if Rakuten expands its footprint outside Japan.
  • Property and construction companies, especially for major regeneration districts or whole new smart-city developments.
  • UC/UCaaS and related voice & communications-centric enterprise SPs, such as Tango Networks with CBRS
  • Universities creating campus networks for students, or other education/research organisations servicing students, staff and visitors
  • Major cloud providers creating 4G / 5G networks for a variety of use-cases and enterprise groups - Amazon and Google are both tightly involved (albeit opaquely, beyond Google's SAS business), while Microsoft's acquisition of Metaswitch points to cloud-delivered private 5G, albeit perhaps not with spectrum and RAN managed itself.
  • Tourism and hospitality service providers providing connectivity solutions to hotels or resorts - although that's probably taking a backseat given economic & pandemic woes.
  • Broadcasters, event-management and content-production companies deploying private networks on behalf of sports and entertainment venues, festivals
  • Dozens more options - I'm aware of numerous additional categories and more will inevitably emerge in coming years. Ask me for details.

Conclusion: beyond the MNO/Enterprise binary fallacy

You get the picture. The future of 4G / 5G isn't just going to split between traditional "public mobile operators" (typically the GSMA membership) vs. individual enterprises creating DIY networks. There will be an entire new universe of SPs of many different types.

You can call them "new telcos", "Specialist Wirelss SPs", "Alternative Mobile Operators" or create assorted other categories. Many will be multi-site operators. Some may be regional or national.

We will see MNOs set up divisions that look like these new SP types, or perhaps acquire them. Some vendors will become quasi-SPs for enterprise, too. This is a hugely dynamic area, and trying to create fixed buckets and segments is a fool's errand.


Understanding this new and heterogeneous landscape is critical for enterprises, policymakers, vendors and investors - as well as traditional MNOs. I've been saying for years that "telecoms is too important to be left to the telcos", and it appears to be becoming true at a rapid pace.

Many in the mobile industry assert that 5G will transform industries. In many cases it will.... but the first industry to get transformed is the mobile industry itself.

Predictions for the next decade: looking out to 2030 for telecoms, wireless & adjacent technologies


It's tempting to emulate every other analyst & commentator and write a list of 2020 predictions of success and failure. In fact, I got part-way into a set of bulletpoints about what’s overhyped and underhyped. 

But to be honest, if you read my articles and tweets, you probably know what I think about 2020 already. Private cellular networks will be important (4G, initially). 5G fixed wireless is interesting and will grow the FWA market - but won't replace fibre. 5G is Just Another G and is overhyped, especially until the new core matures. RCS is still a worthless zombie, eating brains. But I don't need to repeat all this in detail, just because I'm a bit more sharp-worded than most observers. It wouldn't tell you much new.

But seeing as I spend a fair amount of time advising clients about the longer-term future, 5-10 years out or even further, I thought I'd set my sights higher. I use the term "telco-futurism" to look at the impacts of technology and broader society on telecoms, and vice versa.

So, at the start of the 2020s, what about the next decade? Assuming I haven't retired to my palatial Mars-orbiting private Moon in 10 years' time, what do I think I'll be writing, podcasting (or neural-transmitting) about in 2030?

So, let's have a few shots at this more-distant target...

  • 6G: In 2030, the first 6G networks are already gaining traction in the marketplace. The first users are still fixed connections to homes, and personal devices that look a bit similar to phones and wearables, but with a variety of new display and UI technologies, including contact lenses and advanced audio/haptic interfaces. 6G represents the maturing of various 5G concepts (such as the new core), plus greater intelligence to allow efficient operation. 
  • Details, details: Much of the 2020s will have been spent dealing with numerous "back-office" problems that have stopped many early 5G visions becoming real. Network-slicing will have thrown up huge operationalisation and security issues. Dealing with QoS/slice roaming or handoff, at borders between networks (outdoor / indoor / private / neutral / international) will be hugely complex. Edge computing scenarios will turn out to need local peering or interconnection points. All of these will have huge extra complexities with billing, pricing and monitoring. mmWave planning and design tools will need to have matured, as well as the processes for installation and operation.Training and skills for all of this will have been time-consuming and expensive - we'll need hundreds of thousands of experts - often multi-domain experts. By the time all these issues get properly fixed, 6G radios and vendors will exploit them, rather than the "legacy 5G" infrastructure. See this post for my discussion about the telecom industry's problems with accurate timelines.
  • Device-Network cooperation: By 2030, mobile ecosystems and control software will break today's silos between radio network, devices and applications much more effectively. Sensors in users' devices, cell-towers and elsewhere will be linked to AI which works out how, why and where people or IoT objects need connectivity and how best to deliver it. Recognise a moving truck with machine-vision, and bounce signals off it opportunistically. Work out that someone is approaching the front of a building, and pre-emptively look for Wi-Fi, or negotiate with the in-building neutral host on a marketplace before they enter the door. Spot behavioural patterns such as driving the same route to work, and optimise connectivity accordingly. Recognise a low battery, and tweak the "best-connected" algorithm for power efficiency, and downrate apps' energy demand.Integrate with crowd-flow patterns or weather forecasts. There will be thousands of ways to improve operations if networks stop just thinking of a "terminal" as just an endpoint, and look for external sources of operational data - that's a 20th Century approach. Expect Google's work on its Fi MVNO & Android/Pixel phones, and similar efforts by Samsung and maybe Apple, Qualcomm and ARM, to have driven much of this cross-domain evolution.
  • Energy-aware networks: Far more energy-awareness will be designed into all aspects of the network, cloud and device/app ecosystem. I'm not predicting some sort of monolithic and integrated cascading-payments system linked into CO2-taxes, but I expect "energy budget" to be linked much more closely to costs (including externalities) in different areas. How best to optimise wired/wireless data for power demand, where best to charge devices, "scavenging" for power and so on. Maybe even "nudge" people to lower-energy applications or consumption behaviours by including "power-shaming" indicators. If 3GPP and governments get their act together, as well as vendors & CSPs, overall 6G energy use will be a higher priority design-goal than throughput speed and latency.
  • Wi-Fi: We'll probably be on Wi-Fi 9 by 2030. It will continue to dominate connectivity inside buildings, especially homes and business premises with FTTX broadband (i.e. most of them in developed markets). It will continue to be used for primary connectivity on high-throughput / low-margin / low-mobility devices like TVs and display screens, PC-type devices, AR/VR headsets and so on. It will be bonded together with 5G/6G and other technologies with ever-better multi-path mechanisms, including ad-hoc device meshes. Ease of use will have improved, with the success of approaches like OpenRoaming. Fairly little public Wi-Fi will be delivered by "service providers" as we think of them today.  We'll probably still have to suffer the "6G will kill Wi-Fi" pundit-pieces and hype, though.
  • Spectrum: The spectrum world changes slowly at a global level, thanks to the glacial 4-year cycle of ITU WRCs. By 2030 we will have had 2023 and 2027 conferences, which will probably harmonise more spectrum for 5G/6G, satellites & high-altitude platforms (HAPS) and Wi-Fi type unlicensed use. The more interesting developments will occur at national / regional levels, below the ITU's role, in how these bands actually get released / authorised - and especially whether that's for localised or shared usage suitable for private networks and other innovators. By 2030 we should have been through 2+ cycles of US CBRS and UK/Germany/Japan/France style local licensing experiments, allocation methods, databases and sensing systems. I think we'll be closer to some of the "spectrum-as-a-service" models and marketplaces I've been discussing over the last 24 months, with more fluid resale and temporary usage permits. International allocations will still differ though. We will also see whether other options, such as "national licenses with lots of extra conditions" (eg MVNO access, rural coverage, sharing, power use etc) has helped maintain today's style of MNOs, despite the grumbling. We will also see much more opportunism and flexibility in band support in silicon/devices, and more sophisticated approaches to in-band sharing between different technologies. I'm less certain whether we will have progressed much with commercialisation of mmWave bands 20-100GHz, especially for mobile and indoor use. It's possible and we'll certainly see lots of R&D, but the practicalities may prove insuperable for wide usage.
  • Private/neutral cellular: Today, there's around 1000 MNOs globally (public and private). By 2030, I'd expect there to be between 100,000 and a million networks, probably with various new types of service provider, aggregation hubs and consortia. These will span industrial, city, office, rural, utility, "public venue" and many other domains. It will be increasingly hard to distinguish private from public, eg with MNOs' campus networks with private cores and hybrid public/private spectrum. We might even get another zero, if the goals of making private 4G/5G as easy and cheap to build as Wi-Fi prove feasible, although I have doubts. Most of these networks will be user-specific, but a decent fraction will be multi-tenant, either offering wholesale access or roaming to "legacy MNOs" as neutral hosts, or with some sort of landlord model such as a property company running a network with each occupied floor or building on campus as a "semi-private" network. Some such networks will look like micro-telcos (eg an airport providing access to caterers & airlines) and will need billing, management & security tools - and perhaps new forms of regulation. This massive new domain will help catalyse various shifts in the vendor community as well - especially cloud-native core and BSS/OSS, and probably various forms of open RAN, and also "neutral edge".
  • Security & privacy: I'm not a security expert, so I hesitate to imagine the risks and responses 10 years out. Both good and bad guys will be armed to the teeth with AI. We'll see networks attacked physically as well as logically. We'll see sophisticated thefts of credentials and what we quaintly term "secrets" today. There will be cameras and mics everywhere. Quantum threats may compromise encryption - and other quantum tools may enhance it, as well as provide new forms of identity and authentication. We will need to be wary of threats within core networks, especially where orchestration and oversight is automated. I think we will be wise to avoid "monocultures" of technologies at various levels of the network - we need to trade off efficiency and scale vs. resilience.
  • Satellite / HAPS: We'll definitely have more satellite constellations by 2030, including some huge ones from SpaceX or others. I have my doubts that they will be "game-changers" in terms of our overall broadband use, except in rural/remote areas. They won't have the capacity of terrestrial networks, and signals will struggle with indoor penetration and uplink from anything battery-powered. Vehicles, planes, boats and remote IoT will be much better-connected, though. Space junk & cascading-collision scenarios like the movie Gravity will be a worry, though. I'm not sure about drones and balloons as HAPS for mass-market use, although I suspect they'll have some cool applications we don't know today.
  • Cloud & edge: Let's get one thing clear - the bulk of the world's computing cycles & data storage will continue to occur in massive datacentres (perhaps heading towards a terawatt of aggregate power by 2030) and on devices themselves, or nearby gateways. But there will be a thriving mid-market of different sorts of "edge" as I've covered in many posts and presentations recently. This will partly be about low-latency, but not as much as most people think. It will be more about saving mass data-transport costs, protecting "data sovereignty" and perhaps optimising energy consumption. A certain amount will be inside telcos' networks, but without localised peering / aggregation this will be fairly niche, or else it will be wholesaled out to the big cloud players. There will be a lot of value in the overall orchestration of compute tasks for applications between multiple locations in the ecosystem, from chip-level to hyperscale and back again. The fundamental physical quantum of much edge compute will be mundane: a 40ft shipping container, plonked down near sources of power and fibre.
  • Multi-network: We should expect all connectivity to be "software-defined" and "multi-network". Devices will have lots of radios, connecting simultaneously, with different paths and providers (and multiple eSIM / other identities). Buildings will have mutliple fibres, wireless connections and management tools. Device-to-device connections and relaying will be prevalent. IoT will use a selection of LPWAN technologies as well as Wi-Fi, cellular and short-range connections. Satellite and maybe LiFi (light-based) connections will play new roles. Arbitrage, bonding, load-balancing will occur at multiple levels from silicon to OS to gateway to mid-network. Very few things will be locked to a single network or provider - unless it has unique value such as managed security or power consumption.
  • Voice & messaging: Telephony will be 150yo in 2026. By 2030 we'll still be making some retro-style "phone calls" although it will seem even more clunky, interruptive, unnatural and primitive than today. (It won't stop the cellular industry spending billions upgrading to Vo6G though). SMS won't have disappeared, either. But most consumers will communicate through a broad variety of voice and video interaction models, in-app, group-based, mediated by an array of assistants, and veracity-checked to avoid "fake voice" and man-in-the-middle attacks of ever increasing subtlety. Another 10 years of evolution beyond emojis, stories, filters and live broadcasts will allow communication which is expressive, emotion-first, and perhaps even richer and more nuanced than in-person body language. I'm not sure about AR/VR comms, although it will still be more important than RCS which will no doubt be celebrating its 23rd year of irrelevance, hype and refusal to die.
  • Enterprise comms:  UCaaS, cPaaS and related collaboration tools will progress steadily, if unspectacularly - although with ever more cloud focus. There will be more video, more AI-enriched experiences for knowledge management, translation, whispered coaching and search. There will be attempts to reduce travel to meetings and events as carbon taxes bite, although few will come close to the in-person experience or effectiveness. We'll still have some legacy phone calls and numbers (as with consumer communications) although these will be progressively pushed to the margins of B2B and E2E interactions. Ever more communications will take place "contextually" - within apps, natively supported in IoT devices, or with AI-based assistants. Contact centres and customer interactions will be battlegrounds for bots and assistants on both sides. ("Alexa, renegotiate my subscription for a better price - you have permission to emulate my voice"). Security and verification will be highly prized - just because something is heard doesn't mean it will match what was originally spoken
  • Network ownership models: Some networks of today will still look mostly like "telcos" in 2030,  but as I wrote in this post the first industry to be transformed by 5G will be the telecom industry itself. We'll see many new stakeholders, some of which look like SPs, some which are private network operators, and many new forms of aggregator, virtual operator, wholesale or neutral mobile/fibre provider. I'm not expecting a major shift back to nationalised or government-run networks, but I think regulations will favour more sharing of assets where it makes sense. Individual industries will take control of their own connectivity and communications, perhaps using standardised 5G, or mild variations of it. There will be major telcos of today still around - but most will not be providing "slices" to companies and offering deep cross-vertical managed services. There will be M&A which means that we'll have a much more heterogeneous telco/CSP market by 2030 than today's 800 identikit national MNOs. Fixed and fibre providers will be diverse as well - especially with the addition of cloud, utility and muncipal providers. I think the towerco / property-telco model will be important as asset owners / builders as well.
I realise that I could go on at length about many other topics here - autonomous and connected vehicles, the future of cities and socio-political spheres, shifts in entertainment models, the second wave of blockchain/ledgers, the role of human enhancement & biotech, new sources of energy and environmental technology, new forms of regulation and so forth. But this list is already long enough, I think. Various of these topics will also appear in podcasts - which I'm intending to ramp up in 2020. At the moment I'm on SoundCloud (link) but watch out here or on Twitter for announcements of other platforms.

If this has piqued your interest, please comment on my blog or LinkedIn article. This is a vision for 2030, which I hope is self-consistent and reasonable - but it is not the only plausible future scenario.

If you're interested in running a private workshop to discuss, debate and strategise around any of these topics, please get in touch via private message, or information AT disruptive-analysis DOT com. I work with numerous operators, vendors, regulators, industry bodies and investors to imagine the future of networks and other advanced technologies - and steer the path of evolution.

Happy New Year! (and New Decade)

Timing is everything: Why telecom industry visions get it wrong


Introduction

One of the things I find most frustrating about technology forecasts and visions – especially in telecoms and mobile – is the lack of awareness of adjacent issues and trends, or consideration of "gotchas" and alternative scenarios.

So for example, when telcos, vendors or policymakers predict what 5G deployment, or network-slicing, or edge-computing or anything else might result in – applications, uptake, revenue opportunities and so on – they often fail to ask two critical questions:
  • Distractions: What are the prerequisites for this to happen? What are the bits of the overall wider system that are forgotten but necessary, to make the headline technology feasible and useful? And when will they be achieved? What's the weakest link in the chain? Is delay inevitable?
  • Disruptions: What else is likely to happen in the meantime, which could undermine the assumptions about demand, supply or value-chain structure? What's going on in adjacent or related sectors? What disruptions can be predicted?

This post has an accompanying podcast, on my SoundCloud:



Internal distractions & pre-requisites

So for example, for 5G to be successful to the degree that many predict (“trillions of $ of extra GDP”, millions of extra jobs etc) there first needs to be:
  • Almost ubiquitous 5G coverage, especially indoors, in sparse rural areas, and in other challenging locations
  • Enough fibre or other backhaul connectivity for the cell-sites
  • Suitable software and hardware platforms to run the virtualised core and other elements
  • Enough physical sites to put antennas, at low-enough costs & with easy-enough planning
  • Many more engineers trained and qualified to do all of the above
  • A decent business case, for instance in remote areas
  • 3GPP release 16 & 17 to be completed, commercialised and deployed, especially for the ultra-low latency & high-reliability applications.
  • Optimisation and operational systems, perhaps based on as-yet-unproven AI
Yet vendors and policymakers often gloss over these "annoying" practicalities. There seems to be an attitude of “oh, they’ll have to make it work somehow”. Well, yes, perhaps they will. But when? And at what cost? What changes does that imply? How will the gaps and limitations be bridged? And what happens if firms go bust while waiting for it all to happen? What other ways to solve problems can users pursue sooner, that don't involve 5G?

A key implication of this is that timing and profitability of massmarket adoption is often much later than expected. While Amara's Law might eventually apply (we tend to overestimate the effect of a technology in the short run and underestimate the effect in the long term), that doesn't mean that early initial adopters and investors make the returns they'd hoped for.



External disruptions and substitutes

Perhaps even more pernicious is the lack of situational awareness about parallel developments elsewhere in the broader tech ecosystem. These undermine both demand (as alternative solutions become viable in place of the hoped-for technology) and supply / operation (by throwing up new complexities and gotchas to deal with). 

These are often not just “what ifs" but “highly likelies” or "dead-on certainties".

So for instance, the visions of network slicing, or edge-computing for 5G (which will really only crystallise into large-scale commercial reality in maybe 4-5 years) will have to contend with a future world where:


  • 5G networks are still patchy. There will still be lots of 4G, 3G and “no G” locations. What happens at the boundaries, and how can you sell QoS only in certain places?
  • There will be a patchwork of “uncontrolled” locations – they might be 5G, but they could be owned by roaming partners, indoor network providers, private localised cellular operators and so on. How will a slice work on a neutral-host's network?
  • An ever-greater number of devices spend an ever-greater amount of time on Wi-Fi – usually connected to someone else’s fixed-line infrastructure and acting as either uncontrolled, or a direct arbitrage path. 
  • Telcos have to cap their energy use and associated CO2 emissions, or source/generate clean power of their own.
  • Wi-Fi 6 will emerge rapidly & is hugely improved for many use-cases, but most 5G predictions only compare against legacy versions
  • Hardware based on "commodity hardware" runs against the current tide of semiconductor fragmentation and specialisation (see recent post, here)
  • Devices will often have VPN connections, or use encryption and obfuscation techniques, which means the network won't be able to infer applications or control traffiic.
  • Users and devices will use multiple connections together, either for arbitrage, aggregation, or more-sophisticated SD-WAN type models.
  • Pricing, billing, customer support and security will be challenging on "federated" 5G or edge-compute networks. Who do you call when your network-slice doesn't deliver as expected - and how can they diagnose and fix the problem?
  • Liability and accountability will become huge issues, especially if 5G or slicing is used for business-critical or life-critical functions. Are your lawyers and insurers prepared? 
  • AI will be used for instant price-comparison, quality monitoring & fault reporting, collective purchasing and even contractual negotiations. "Hey, Siri, mimic my voice and get me the best discount possible with the customer-retention agents"
These are just some basic examples. Once you get into individual verticals, particular geographies or even specific companies, a whole host of other issues start to crop up  - sector regulation, value-chain shifts, government involvement, expectations of 20-30 year tech cycles and so on. Sure, in theory 5G might fit into various industries' own transformation journeys - but they won't design around it.


Conclusions

I find this all very frustrating. So many company boards, strategy departments or lower-level product/service management teams seem to operate on the basis of "all other things being equal..." when the one certainty is that they won't be



So the two sets of factors tend to be multiplicative:
  • Distractions are internal to a new concept, and lead to delays in technology launch, market maturity and revenue.
  • Disruptions are external and often inevitable, but any extra delay increases their range and impact yet further.
It's never possible to predict everything that might get delayed, or every possible disruption from adjacency. But it seems to me that many companies in telecoms don't even bother to try. 

Companies accept the "hype cycle" as inevitable, even if it might be possible to flatten it out.

By coincidence, while writing this post I started reading "Range" by David Epstein (link) which talks about the importance of "analogising widely", and the risks of narrow expertise and superficial analysis, rather than looking for implications of cross-sector / cross-discipline similarities and lessons. 

When evaluating new technologies and service concepts, CEOs and CFOs need to rely less on familiar industry echo-chambers and consensus hype, and instead seek out critics who can find hidden assumptions, both internal and external to their plans. This isn't just a negative exercise either - often, a "ranging" exercise throws up unexpected positives and opportunities from adjacency as well risks.

Footnote
 
I sometimes get asked to "stress test" ideas and plans, and help companies avoid expensive mistakes, get started on future glitches today, or prepare for and avoid contingencies and unintended consequences. 

Often, that exercise will throw up new opportunities as well. Usually, a collaborative (but candid) group workshop ensures this isn't a blame-game, but a path to smoother growth and innovation. The skills and mindsets can be learned and replicated, too.

If that type of approach sounds interesting, please get in touch with me, either by email (information AT disruptive-analysis DOT com) or via LinkedIn (link).
