6G won't wait. Will traditional MNOs still be the main customers when it arrives?

 One line I heard yesterday at #ConnectedBritain that really struck me came from BT Group Network/Security head Howard Watson during his keynote.

He was hoping #6G arrived later rather than earlier, "For the Brisbane Olympics, not LA", ie 2032.

This is not the first time I've heard an MNO exec expressing a desire to let #5G run longer, before 6G prompts more Capex and infrastructure changes. They want to get payback on existing investments before thinking about the next round.

This is unsurprising. The industry itself now recognises that it overhyped 5G before launch, and completely forgot to mention that it would arrive in phases, with all the "cool stuff" really only arriving in later versions, with the features in 3GPP Releases 16, 17 & 18.

Instead, we started with 4G++ (ie non-standalone 5G, with sometimes higher speeds but not much else) and then the first versions of "proper 5G" with the Release 15 standalone cloud-native core.

5G SA gives somewhat lower latency, and some rudimentary QoS and other features, but it's far from the ubiquitous millisecond / gigabit / slicing nirvana that everyone promised in 2018.

I was skeptical from the beginning - and I'm still a "slice denier". (I think #networkslicing remains a critical strategic error and distraction for the industry). But my view is that the really useful stuff in 5G, such as time-synchronous networking, RedCap and vertical-specific elements such as FRMCS for railways, are still a long way from mainstream.

So I can understand that MNOs look at the proposed 6G timeline of 2030, and think "we're still making heavy work of moving to cloud-native 5G standardalone. How are we going to do successive iterations of R15 SA, R16, R17, R18, R19... and make money, all within 6 years?"

[Note: technically 6G should start with Release 21, but based on past experience we'll see R20, or maybe even R19, marketed as 6G by some MNOs]

There is a possible uncomfortable answer that's starting to get discussed quietly. What if 6G isn't primarily about MNOs, at least at first?

6G will happen in 2030, one way or another. The world's universities and R&D labs aren't going to down tools for two years, while MNOs are still trying to "monetise" 5G. There will be a bunch of technologies and standards that get called IMT2030 / 6G.

There might even be multiple standards, either because of geopolitics leading to regional versions, or because my niggling of IEEE and Wi-Fi Alliance eventually prompts them to submit a candidate 6G technology (#WiFi 9 or 10, I guess).

So the question then becomes - will traditional MNOs be the main buyers of 6G in the 2028-2030 timeframe? Or will it be enterprises, new-entrant and niche MNOs, infracos, neutral-hosts, satcos, governments and others building greenfield wireless networks?

Is the failure of 5G to live up to inflated expectations actually going to be the pivot point for the (slow) demise of the legacy MNO model? Are we watching #pathdependency effects in play?

 

Enterprise 5G - evolving bottom-up from small islands, not top-down from national networks

This post originally appeared on September 29 on my LinkedIn feed, which is now my main platform for both short posts and longer-form articles. It can be found here, along with the comment stream. Please follow / connect to me on LinkedIn, to receive regular updates (about 1-3 / week)

While the broad concept of #privatewireless seems to be getting a lot more awareness in the wider tech industry, some of the implications haven't quite fully landed yet.

I've had a couple of meetings recently where there was still a prevailing view that #5G evolution would continue to be "top-down", with major MNOs setting the agenda, especially for enterprise. The belief is that national "umbrella" networks would address all the various localised applications, such as #industry40 and #smartagriculture, or #v2x networks along roads.

Such a set-up would mean that the network "mothership" would need all sorts of cloud-native elements for orchestration, security and control systems, both at the telcos and their clients, which would be a boon for vendors expecting a direct correlation with the promised $xxx billions of 5G value, coming from URLLC capabilities, slicing and other features.

But what is happening is much more bottom-up. The most cutting-edge uses of 5G are happening at specific locations - whether that is standalone networks at factories, or new #neutralhost deployments in offices and hotels (more on NH's in my next post btw). We can expect Release 16/17/18 features to appear at a micro level, long before they're switched on for the macro domain.

And while these small local networks are sometimes being deployed by MNOs, they are often based on dedicated infrastructure, perhaps using different vendors to the main umbrella national networks. It's often the B2B units running the show, with a variety of partners, rather than the central core network team.

Other small islands are getting their networks built by integrators, towercos & infracos, inhouse teams, industrial solutions suppliers and assorted others. It's very heterogeneous.

And each island can be *small*. A port's 5G network might have huge value for the site's operator, but only have 100 SIMs in cameras and vehicles. There might be redundancy, but it won't need a datacentre full of kit. There's often going to be a lot of customisation, and unique combination of applications and integrations with other systems

So if you're a vendor pitching umbrella-grade solutions, you might need to rethink how to re-orient towards small islands instead.

 

Train connectivity - is passenger Wi-Fi too linked to rail portals' needs?

This post originally appeared on Oct 5 on my LinkedIn feed, which is now my main platform for both short posts and longer-form articles. It can be found here, along with the comment stream. Please follow / connect to me on LinkedIn, to receive regular updates (about 1-3 / week)

It's always interesting to attend non-telecom industry events. Too often, we breathe our own smoke. Visiting another sector's conferences gives better perspective. Often, networks are less important than we imagine for "verticals".

Yesterday I chaired the Connectivity stream of the World Passenger Festival conference in Vienna, an event primarily for the rail industry, plus other forms of transport mobility. The speakers in my breakout covered Wi-Fi access onboard trains and at stations, plus how to manage video traffic. 5G was covered for on-train network backhaul, neutral-host provision and possible use-cases like AR-enabled tourism & urban mobility V2X safety for buses and bikes.

The rest of the conference and show floor was about passenger experiences more generally. Ticketing, sleeper trains, coordination with other types of transport, train-based tourism and so on. Plenty of talk about apps and "transformation" more broadly, but the network wasn't a priority.

There was also a rather muddled main-stage keynote on #5G by Accenture, with 2018-era references to millisecond latencies, network slicing and autonomous vehicles. It conflated normal MNO 5G with the long-promised critical-comms rail variant #FRMCS and bizarrely suggested they would coexist on converged, virtualised networks. A later chat on their booth with a more knowledgeable colleague gave a lot more clarity & agreement on the realities & drivers of operational connectivity for future rail - especially enabling ECTS (European Train Control System) for higher capacity on rail networks.

The rail industry is at the apex of a trend I discussed in a recent newsletter article and post - the need for customers to have reliable access to smartphone apps for ticketing, journey-planning, at-seat entertainment and catering etc. Travellers need to download passes, make payments and use QR codes.

This explains why so much of the on-train #WiFi strategy is linked to apps and portals, and much less to general wireless infrastructure, whether MNO or dedicated trackside/FRMCS.

Some rail Wi-Fi teams view cellular as a cost (for backhaul) or a rival that stops passengers seeing the portal and info/monetisation offers, when they directly access the Internet from phones. They filter or cache video use to reduce cost and congestion. One even tries to dissuade passengers from using cellular, to save 4G/5G network capacity for the train!

In my view, there is both too much "joined-up" thinking and too little. It's either 5G maximalism ("we don't need Wi-Fi on trains") or it directly links connectivity to the rail operator's own priorities, rather than passengers' real Internet access needs and expectations.

What is needed is integration in the right places and layers. Shared trackside masts and fibre, plus hybrid connectivity to trains from public 5G, trackside dedicated networks (including #private5G) and satellite, delivering good, neutral, fast on-train Wi-Fi AND cellular for passengers.

 

Connectivity on trains is hard - but both Wi-Fi and cellular need to be provided for passengers

This post originally appeared on May 24 on my LinkedIn feed, which is now my main platform for both short posts and longer-form articles. It can be found here, along with the comment stream. Please follow / connect to me on LinkedIn, to receive regular updates (about 1-3 / week)

 There have been recent headlines about the possible ending of on-train passenger #WiFi services in the UK. It is deeply controversial.

Apparently the Department for Transport (DfT), United Kingdom has insisted rail WiFi must be "justified financially". It's unclear if that means by extra ticket sales, higher customer satisfaction, or the use of WiFi for #train operational functions like cameras and wireless payment terminals.

I hope it's not referring to so-called "monetisation" by customers paying for WiFi, or being served adverts. On trains, WiFi is a basic amenity, like toilets or power sockets.

That said, train WiFi in the UK is often problematic. It uses clunky captive portals, and often old access points & slow/patchy 4G backhaul. It often fails to work well, or at all. It sometimes blocks video or VPNs. By contrast, in-station WiFi is run separately - and often much better.

Public cellular coverage on the rail network is also poor. Many rail lines run through cuttings and tunnels with limited room for trackside infrastructure & poor lines-of-sight to cell towers. The recent Department for Science, Innovation and Technology Wireless Infrastructure Strategy highlighted poor #railway #wireless coverage & pushed for regular monitoring and access to trackside fibre.
 
What should DfT, DSIT, Network Rail, Train Operating Companies and the future restructured Great British Railways Transition Team (GBRTT) do?
 
- Recognise both cellular & WiFi are essential for passengers, especially on long-distance trains where laptops are common
- Understand that cellular - especially #5G - has problems with signals reaching inside train carriages
- Don't underestimate forecasts for future data use. Add in uplink as well as downlink, and think about latency. Trains may need 1-5 Gbps in the medium term, via a mix of cellular & WiFi.
- Ensure on-train WiFi is easy to use & easily-upgraded. No captive portals, no “monetisation” with ads/data capture & a clear roadmap for regular upgrades. No blocking of any apps, especially VPNs and video. Apply Net Neutrality rules.
- Federation or roaming between on-train & station WiFi systems, extending to smart cities & metro bus/train/tram WiFi over time
- Easier access for MNOs / #neutralhosts to build trackside or near-track infrastructure & use gantries & fibre assets
- Decouple passenger connectivity needs from future critical #FRMCS deployment. They have different timing/cadence & investment cases
- Look at trackside 5G neutral host networks delivered with “excess” spectrum from any future 4-3 merger of MNOs
- Insist on-train gateways are modular & can use a dynamic mix of public 5G, trackside wireless & eventually satellite in remote areas. Ensure they are easily upgradeable without trains being taken out of service
- Upgrade on-train signal repeaters & look at window-etching for better outdoor-to-indoor performance

Note: I wrote this on WiFi on a train back to London from this week’s Wi-Fi NOW conference.

 

A new view on Neutral Host - the role of cities and municipalities

This post originally appeared on Apr 17 on my LinkedIn feed, which is now my main platform for both short posts and longer-form articles. It can be found here, along with the comment stream. Please follow / subscribe to receive regular updates (about 1-3 / week)

I'm at the #ConnectedNorth event in Manchester today and tomorrow. There's a lot about gigabit fibre rollouts and uptake, as well as a big emphasis on connected communities and cities - but this post is about mobile densification and small cells.

A key theme here is the fast-evolving model for #neutralhost mobile for small cells and network capacity in-fill in cities. An NH is a 3rd party wholesale provider which enables multiple tenant 4G/5G mobile providers - generally MNOs, but also potentially including private networks as well.

A few years ago when I was running NH workshops with Peter Curnow-Ford we identified this area of metro infill as one with potential, but limited actual deployments.

There are numerous challenges - MNOs ideally don't want separate deals with each city authority, while cities don't want multiple MNOs independently requesting 100s of sites with associated street clutter, road closures and soon. Authorities also want to both make money from access to assets such as lampposts, and to improve connectivity for citizens and businesses as fast as possible.

One option floated was for authorities to build out their own private 4G/5G networks, then allow MNOs to roam onto them, or use some sort of MOCN network-sharing arrangement. But MNOs each have different coverage / capacity holes, different spectrum bands, different customer groups - and also worry about security, ability to manage radio units, do carrier aggregation and so on. The idea of a single cell network in its own spectrum, with multiple MNO tenants is appealing, but sometimes unworkable. (It might work OK in villages or indoors, though).

What's happening is that another model is evolving. Local authorities like city councils are contracting with several infrastrucure specialists - companies like Cellnex UK , Freshwave, Ontix, BAI Communications and Shared Access to run (essentially) small-cell as a service offers. These act as intermediaries, allowing local authorities to create standard contracts, and for MNOs to have standardised processes for getting access at each site.

It reduces the frictions and costs of the paperwork - and also allows for infrastructure-sharing to evolve over time where it makes sense. Coupled with vRAN or open RAN it can put some of the electronics into central facilities, reducing street-side box numbers. And it means MNOs can get coverage in their preferred locations, with backhaul/fronthaul and power supplies simplified.

The competitive infraco/towerco angle, rather than exclusive area concessions, allows MNOs to choose the provider that is the best fit - and without needing different processes in each city.

It's not quite what I expected NH models to look like - and they may differ in the US or across Europe - but it seems to make good sense here in the UK.

 

Update: Recent Posts & Themes

(This article was initally posted on my LinkedIn newsletter. If you are not already signed up, please subscribe here)

I have a couple of other deep-dive themes cued up for articles in coming weeks, but I wanted to put out a quick newsletter update covering a few recent themes, posts and events that have been occupying me.

 

The last month has featured a lot of thinking, speaking & client engagements on private 5G, infrastructure-sharing and neutral-host business models, network slicing and capability/API exposure, Wi-Fi 6E & 6GHz, Open RAN and the interaction of cellular & other wireless technologies.

Some recent short-form posts that you may have missed:

• Telecom operators (and their partners & regulators) should be giving as much consideration to *buying* APIs and capabilities as selling them - LINK
• Thoughts on the Ericsson / Vonage acquisition - LINK
• Should we be thinking more about "micro-churn" incidents, where subscribers temporarily switch between operators, using technologies such as eSIM? - LINK
• Want me to speak at, or moderate your 2022 event? Or present at an internal workshop or offsite? - LINK
• RCS messaging is still a purposeless zombie technology, continuing to eat brains after 13 years. Google's involvement hasn't changed much - LINK
• The telecoms industry still hasn't gone beyond telephony, to think more broadly about "voice" services & applications - LINK

I've been to a couple of recent "verticals" events, about networking in ports and for railways. There's a lot of interest in private cellular - but also a huge amount of emphasis on Wi-Fi, including specialised versions with 60GHz or unique forms of QoS intended for industrial or trackside use.

I also presented on a webinar recently on behalf of iBwave, about the scope for Private 4G/5G networks for utilities and energy companies (LINK to view on-demand). Watch out for an upcoming eBook on the same topic. Another webinar on the competiton/convergence between Wi-Fi6 and 5G was for Spirent (LINK) 

 

Scott and Iain at Telecoms.com invited me onto their weekly podcast for a (rather irreverent) chat about the current trends and news from the industry, over a couple of beers. We took aim at 5G, the Metaverse, Open RAN & a lot more. YouTube link embedded above!

In addition, I moderated a panel on Infrastructure Sharing for the 5G Techritory event. I'm not sure if an archived version will be put online, but keep a watch out for it here.

And on a personal note, I also took part in my first improv comedy performance. If you book me to speak at one of your events, I can't promise to wear the same shirt as in the picture, but I will certainly be happy to make things up on the spot spontaneously, or deal with any hecklers ruthlessly!

The fake battle: 5G vs Wi-Fi

[Reposted from my LinkedIn & slightly extended. See the post here for a full comment thread]

I'm bored of the fake battle being hyped up between #WiFi and #5G, especially for enterprise connectivity in-building.

Let's be absolutely clear. Essentially *every* building, whether residential, enterprise office, public venue or industrial, will need good WiFi coverage, increasingly based on #WiFi6.

Most laptops, TVs, screens, voice assistants, tablets, consumer appliances & other non-smartphone devices will be WiFi-only. Only a handful will have cellular radios too - the economics & manufacturing/distribution complexities don't work for including 5G as a default in most electronic products.

Almost every building will *also* need decent indoor public 4G/5G broadband coverage, especially for employees' and visitors' phones. In most cases this will need to cover all major MNOs' networks, as well as public safety systems such as critical-communications LTE. (Wi-Fi Calling doesn't work ubiquitously on all phones / mobile networks on enterprise Wi-Fi, so there will always need to be a cellular network for reliable basic telephony).

*Some* buildings will also need indoor private 5G for ultra low-latency machines or other connected devices. For industrial sites this will mostly be isolated local networks. For others it may be delivered by MNOs via local coverage or network-slicing, or by some form of neutral-host wholesale model.

The main competition for indoor 5G is actually indoor 4G, not WiFi for which there is only a narrow overlap in use cases. WiFi will almost always be needed as well as cellular, with very rare examples where it's absent - for instance outdoors on campus sites.

Also, future visitor access to WiFi may be made much easier with #OpenRoaming, which can use multiple affiliation-based credentials, not just SIM or passwords. That will change the usability barriers for Wi-Fi, for instance if you can connect via a loyalty app, rather than needing to visit a web-page and enter credentials.

Bottom line: it's not a battle. Wi-Fi6 and 5G will be needed for different purposes. They probably won't be integrated much either, as they'll have different financial models, different usage models (and locations) and deployment/upgrade timelines. Think divergence, not convergence - although some elements such as planning tools and fibre backhaul to the cells/APs will likely be combined.

Industrial 5G networks will mostly be discrete and isolated

A key argument cited for telcos having a central role in industrial / vertical #5G networks is "service continuity". Devices and users can connect both on-premise and in the wide area, because both are enabled by the same operator. An MNO can thus best provide on-premise connectivity as an extension, or slice, of its normal national cellular network.

MNOs and industry groups often assert this to dissuade governments and regulators from assigning local spectrum licences directly to businesses.

This argument doesn't stack up, for several reasons.

On a recent virtual event I moderated for Nigel Yeates Juliet #5grealised the speaker from Three. Business pointed out that its customers' private 4G/5G networks were generally isolated, not part of 3's macro network. They even use different spectrum. They can do roaming, but it's not a priority.

A central point is that most connected IoT and automation systems don't move outside the facility. Industrial robots don't go for a walk to the shops. What does move are vehicles, personal devices and shipped electronic goods.

Yet here, having local & wide area coverage from the same MNO is of minimal use. Guests, contractors and employees have devices on *all* networks, not just that of the on-prem network operator.

So some sort of roaming or neutral-host arrangement would be needed. And those capabilities could be also be offered a new specialised provider, as well as by an incumbent MNO.

In fact, it might be easier (and quicker) for a genuinely neutral wholesale player to offer that capability, rather than one MNO trying to negotiate a site-specific roaming or interconnect deal with all its rivals.

Another reason is eSIM and dual-SIM. Devices can have separate profiles for on-premise and wide-area subscriptions, and just switch from one to the other when they're off-site. This is an increasingly common feature in smartphones and vehicles.

In fact, private cellular networks don't even need SIMs - 5G allows the use of other identifiers such as enterprise security credentials, or even the new Wi-Fi OpenRoaming model.

At a radio level, there are distinct advantages to running private networks in isolated fashion, in separate spectrum. They can use different configurations to the macro environment, perhaps optimised for a different mix of up- and downlink in TDD spectrum.

And lastly, it is much easier to treat a private network as private, rather than some unusual public/private hybrid. The legal situations and liabilities are clearer. SLAs can be described and enforced in contracts. There doesn't have to be alignment in deployment speeds or priorities. Different vendors can be chosen.

This doesn't mean that MNOs don't have a role in such private enterprise networks - but it's likely to be done by a separate business unit that can engineer solutions specifically for verticals, thinking about the customer first. It won't be done by the main "mothership" network group, desperate to find "5G use cases" and crowbar-ing its main network (and also its #networkslicing and #edgecomputing platform) into unsuitable applications.

That MNO enterprise business unit might decide the macro RAN is suitable for a given client. Or it may choose to build its own network locally, with the enterprise owning the spectrum license. Or it might work with 3rd parties - or use WiFi instead. I'm expecting MNOs to acquire lots of vertical-specialist integrators and network installation firms in some industries like manufacturing, ports, mining and healthcare.

Maybe over time they'll add value and revenue to the central 5G network business, or act as channels for its #URLLC and MEC businesses. But that won't be their only offering - just one of a portfolio of options.

More generally, all of this points to private 4G/5G networks - especially in industrial sectors and areas such as ports and mining - being based on discrete, isolated deployments. There may be involvement by a national MNO in its deployment or operation (or spectrum licensing), but the network usually won't be part of an MNO's main infrastructure. There might be service continuity - but there's many ways to offer that, and it usually won't be in the top 10 priorities considered.

I definitely think that the roaming approach and neutral-host model offer many opportunities connected to private cellular too. There's some interesting angles relating to Open RAN here as well. Unfortunately, many of the verticals holding most appeal - hotels, airports, stadiums, office complexes - have obvious problems for the next year or so, given the pandemic and ensuing recesssion.

I'll be exploring these issues at a couple of different upcoming events.

Firstly, on July 7th, I'm running my next private workshop on Neutral Host Networks with Peter Curnow-Ford. It's now switched to a virtual event, over morning and afternoon sessions - plus a networking event (a virtual "pub" with special entertainment) in the evening. The broad outline is the same as first announced (link here) with more detailed updated agenda and format in the next couple of days. It will remain as a private, off-the-record event under the Chatham House Rule.

Also on August 20th, I'm doing another #5GRealised session with Juliet Media, specifically on the role of telcos in private networks. Details are here

As always, this theme and broader area is one I also advise on privately. Please drop me a message if you have specific needs for consulting or insight.

3rd Neutral Host Workshop + OpenRAN for shared networks. Early bird still available

NOTE: Owing to uncertainty around the impact of Coronavirus on travel, event attendance, company policies & venues, this workshop has been postponed from 31st March until 7th July. We have contacted existing registered attendees to discuss the options

On March 31st  July 7th I'll be running my 3rd public workshop on Neutral Host Networks in central London, together with colleague Peter Curnow-Ford.

As well as covering the basics of new wholesale/sharing models for MNOs, both with and without dedicated spectrum, we will also be looking more closely at the fit between NHNs and new virtualised vRAN / OpenRAN technologies. 

We'll cover all the various use-cases: metro-area network densification, indoor systems for various venues, road/rail coverage, rural wholesale models, FWA and more. 

The links (and differences) between neutral-host and private LTE/5G will be discussed, as well as alternative models such as multi-MNO sharing or national roaming. (see this post for some previous thoughts on this)

Different countries' competitive, regulatory and spectrum positions will be covered, to assess how that will impact the evolution of NHNs. 
 
Early bird pricing is available before June 7th.

Full details and registration are available here

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)
