10 initiatives to drive a digital economy

A fully digital economy depends on universal, good quality connectivity, which will increasingly be wireless to support ubiquity and mobility. Without that, many digital enablers will be impossible to achieve. In a month in which GSMA and the UK’s Department of Culture, Media and Sport issue reports that put connectivity centre stage, we examine the challenges and disruptive alternatives to the status quo.

  1. Match service delivery to real world requirements – In an era in which network slicing will soon be able to facilitate logically separate network sharing of common infrastructure and spectrum, move away from the idea of uniform connectivity. Each sector, service and vertical has different requirements on data rate, reliability, latency and value.
  2. Unleash the power of the network – Split the market between infrastructure operators (netcos) and service providers, not MNOs and over-the-top providers. Allow more services to harness the network itself.
  3. Get creative with spectrum – Technical developments will enable MNOs to use unlicensed spectrum in tandem with licensed spectrum, and allow sharing of all spectrum and infrastructure by different service providers who operate independently – while offering service quality guarantees. Encourage competition between service providers – who can compete on a price versus service basis. Consider opening up new spectrum allocations to be ‘shared’ with organisations that ‘qualify’ – so not unlicensed – but open up the market to all players – who can be tenants on an infrastructure using their own spectrum or paying to share others spectrum.
  4. Get even more creative with spectrum – Some areas have poor mobile connectivity – and these are areas where spectrum is under-utilised. Allow local authorities/communities to take responsibility for improving their infrastructure. If operators choose not to benefit from neutral host provisioning, then authorities can do so and operators should be obliged to support national roaming. This would undoubtedly ruffle feathers, but it would also provide an incentive where the market has, to date, clearly failed
  5. Understand the real value of spectrum – There are misperceptions about the value of future spectrum awards (the marginal value of what’s to come will be significantly less than governments are used to). Real Wireless believes the spectrum release process should prioritise the economic and social benefits of connectivity over a one-off injection of revenue from auctions – this will encourage a longer term view of investment in a service rather than the short term view of the cost of the spectrum.
  6. Forge new value chains – The mobile business model is subject to change. Increasingly, mobile access will be requested by and funded via apps and services instead of a fixed or mobile subscription. The market structure to support this will challenge the traditional telecoms model and require a market structure to allow innovation without removing viable competitive players.
  7. Simplify deployment processes – Network deployment and maintenance is a slow, cumbersome and expensive process. This is usually blamed on planning and regulation and there is undoubtedly a great deal that needs to be done in this context. But operators and vendors must also look to their internal processes to identify how they can simplify and improve delivery. How many engineers and touch points are really required before a small cell or DAS goes live?
  8. Make the most of what you’ve got – Globally, many operators are struggling to transform their operational practices to utilise software driven system enhancements to LTE; increasing the utility of automation and AI. Real Wireless believes that it’s in everyone’s interests to invest in software and systems skills and in testbeds for all kinds of wireless, not just 5G. This is crucial to achieve a digital economy, and critical in laying the foundations for future networks where competitive advantage will derive from software oriented innovation paradigms.
  9. Open up access to sites and fibre – Today, mobile operators are monitored to ensure that there is effective competition. However, MNOs rely on a supply chain to deliver their services. In some areas, MNOs are subject to monopolistic or oligopolistic practice from landowners, backhaul providers or commercial property owners. Where landowners have a monopoly on large swathes of land or property, the community loses the economic benefit of connectivity. Competition in the supply chain to MNOs should be subject to review – and comparison to the costs borne by other utility providers.
  10. Incentivise best practise and innovation – Narrow performance gaps between different regions through regulation and incentives, measuring quality of service and quality of experience, not just coverage.

Customising the digital economy

The one-size-fits-all network model is not dead yet. But it’s already starting to fall over. However it is defined, 5G is not going to operate in the same way in all cases: the various areas of bandwidth being reserved for it will see to that. High peak data rate and IoT (Internet of Things) capability, for example, each make very different demands on, and may use very different parts of, the radio spectrum.

For example, at parts of the spectrum above 30GHz early 5G users will take advantage of the high-capacity and high-speed mobile communications that such bandwidth allows. But these benefits won’t initially be matched by coverage. Thus a workable model here could be campus networks for businesses.

However, for IoT, what matters is range, battery life and cost, not throughput. Millions or billions of sensors sending out tiny pieces of information will offer data that can be used to enhance business practices and improve efficiency. This may imply different equipment, and will require different business models and network management systems from basic voice or mobile broadband.

For consumers it’s different again, though what they will want is hard to say just yet. Whatever 5G is used for, promoting the impression that it is one all-encompassing fast broadband network concept is not going to encourage innovation — or indeed be a reflection of reality.

Hence the much-discussed concept of 5G ‘leadership’ needs to be refined. 5G includes technologies that can and will mean different things to different sectors. Real leadership will involve not pushing 5G as broadband for all users everywhere but understanding and explaining what it can offer to specific sectors and users and how that can be tailored, delivered and marketed.

It will therefore be important to ensure that 5G consultation is held with all relevant sectors, and governments should facilitate prioritization of resources according to areas of economic impact. It will also be important to create the regulatory environment for key verticals to have access to optimized wireless networks, rather than assuming that one size fits all.

This way the improved service 5G will bring can benefit mass markets, while customised services enabled by 5G can be, as it were, made to measure for automotive, transportation, healthcare, energy, manufacturing, and more. Each sector and service requires different levels of speed, security, reliability and latency. And each service model will have different attributes and benefits customised to need and budget.

This is also a technology play as well as an economic and regulatory one. 5G NORMA — Novel Radio Multiservice adaptive network Architecture — in which Real Wireless is playing a leading role — aims to develop a conceptually novel, adaptive and future-proof 5G mobile network architecture that will be able to offer network customizability, in particular using available infrastructure more efficiently to meet growing traffic volumes and growing demand for novel communication services.

So, yes, the decline of one-size-fits-all is a good thing when addressing different industry sectors. Driving the digital economy should be more than a nice, catchy slogan. The economic and social benefits of 5G differ by sector and should be examined, discussed and delivered accordingly.

Local government, 5G and the question of funding

The Department for Culture, Media & Sport (DCMS) has just published Next generation mobile technologies: A 5G strategy for the UK. The report argues that delivering 5G should be regarded as a key driver of the UK’s modern industrial strategy and the DCMS has put councils at the heart of its plans to deliver next generation mobile technologies.

This latest government strategy paper on 5G ­has been welcomed across the industry and it singles out local government as being central to its delivery – with clear implications for funding.

Councils will play a critical role in developing and delivering digital infrastructure because of the many roles it plays; from planning and asset management; to community engagement and economic growth. And councils who are actively looking to create connectivity plans and engage with the telecoms sector, will be rewarded.

To be at the forefront of the government’s plans and funding, councils need to:

  • Be ready and willing to negotiate with the telecoms sector, drawing on all of their experience (good and bad) from delivering faster broadband.
  • Draw up a detailed asset management plan for deployment of digital infrastructure, looking at possible sites for base stations (lamp posts, bus stops, public buildings)
  • Review existing planning policies – are they 5G ready and what are the planning barriers to deployment?
  • Don’t just think about 5G – are there any other creative ways to improve mobile connectivity for their residents? If 3G and 4G are still a problem, what other technologies are available to help?

The DCMS is looking at devolving powers, budgets and responsibilities to local areas to accelerate the implementation of 5G. There’s no doubt that proactive councils will be first in line to receive any funding and they will also have the best chance of being selected for pilot programmes.

Our advice is to get involved early. As key advisors to business, government, regulators (Ofcom) and the industry on this issue we welcome the government’s strategy and are keen to work with local councils to drive it forward.

10 things to ask the new Minister for Digital Future

Just before Christmas, the National Infrastructure Commission (NIC) published Connected Future, looking at what the UK needs to do to become a ‘world leader in 5G deployment’.

The media reporting focussed on the revelations that the UK’s 4G coverage is worse than that of Albania and Peru (a claim since questioned by Ofcom) and hailed 5G as the opportunity to put things right.

As the authors of a paper that contributed to the NIC’s final report, we’ve watched the media fall out with interest. We don’t share the nation’s obsession with next generation labels, but we are interested in the recommendation that the government appoints a digital champion, or cabinet minister, to take responsibility for our digital future.

Because connectivity is as important to consumers and business, as gas and electricity. And it’s our conviction that we can’t wait for 5G in 2020 to ‘put things right’, we need to get the basics right now.

So Cabinet Minister for our Digital Future, here are the 10 things we need you to do:

  • Exploit the capabilities of 4G and focus on truly universal wireless coverage at last (e.g. bring connectivity to not-spots and rail), predictable and consistent speeds more important than peak speeds. (More targeted Government funding or carrots/sticks for MNOs).
  • Create the regulatory environment for key verticals to have access to optimized wireless networks, not one size fits all – e.g. incentivize MNOs to invest in network slicing.
  • Lower barriers to entry for new MVNO operators e.g. with flexible spectrum pricing and allocation, more shared/unlicensed spectrum.
  • Post-Brexit, create a net neutrality program which allows investors in networks to monetize their infrastructure effectively (e.g. high QoS services) while retaining open access to core services.
  • Create meaningful structures for dialog between spectrum owners and vertical industry players (e.g. transport) to break down the mistrust, and ensure advanced 4G and 5G serves more than one vertical.
  • Provide support and funding for integrated smart city initiatives – reduce rates and incentivise investment by making access to publically owned assets easier.
  • Invest in radio skills and in testbeds for all kinds of wireless, not just 5G.
  • Ensure that 5G consultation is held with all sectors, and prioritize resources according to areas of social and economic impact – forget about 5G ‘leadership’
  • Ensure that all new or upgraded buildings and infrastructure such as road and rail network are obliged to consider how wireless communications will be deployed in the environment they are creating.
  • Encourage and incentivise private investors to make greater use of shared infrastructure (structures, transmission & power) to deliver wireless services.

Who really needs near-zero latency?

One of the ‘generational’ shifts associated with 5G is the promise of near-zero latency. Now for most engineers, the reduction of latency is generally seen as a necessary good, which is why putting it at the heart of the 5G value proposition is so rarely questioned. But when it comes to making the business case for 5G, it’s important to start making judgements about how much value can be attributed to ultra-low latency and the use cases in which it is mission critical.

It also means making a call about when such applications are likely to achieve the critical mass necessary to deliver significant and sustainable returns that justify investment.

Latency has fallen across the cellular generations. It was around 500ms with 2G, perhaps 100ms with 3G and around 30-50ms with 4G. As surveys have noted, falling from 100ms in 3G to 50ms in 4G has improved user satisfaction. Further improvements may be both harder to deliver and have less impact and ROI associated with them.

Current LTE networks deliver a theoretical latency across the radio interface of 10ms, which translates in practice to around 40ms once delays in the core and external networks are taken into account. Improving this latency would not materially change the experience for most use cases.

For example, video streaming can accommodate very high latency using buffering. Web browsing does not improve materially with latencies below about 50ms. For any application with video it is worth remembering that the frame refresh rate on most devices is effectively 25Hz – which means a video frame is replaced by another every 40ms, generating the perception of a moving picture. Having a latency below 40ms does not help for such applications since the video will not refresh faster – and even if it did it would not be perceptible.

So where might significantly lower latency help? Possibly with ‘tactile’ communications, where a user is remotely controlling a robot using, for example, a special glove, which provides feedback on the touch sensation although there is some debate over whether latencies lower than 20-40ms are needed for this. But this is likely to be an indoor application where a wired or short-range wireless solution is more likely to be used.

Some claim low latency is needed for control of autonomous vehicles. However, it is likely there will be reluctance to depend upon low latency network connectivity for emergency situations such as harsh braking from a nearby car; direct car-to-car communications and advanced sensors are better suited to this situation.

Of course, the lower the latency the better, but it is hard to see any economically compelling cellular applications where reducing latency below that of LTE, the latency performance of which is still being improved by the standards, would make a material difference to the user experience.

At Real Wireless, whilst we are fully behind research towards future low latency communications technologies, we believe that there are still significant gains to be had from leveraging the full value of LTE investments and that delivering such capabilities to the sectors and communities that can most benefit from them must remain an urgent priority.

Complexity made simple – Mark Keenan, CEO, Real Wireless

Real Wireless is ten years old. For ten years we have been at the leading edge of our industry, growing our business and establishing ourselves as the world’s leading wireless experts.

And in that decade, wireless technology, services and demand have undergone a transformation few predicted. Indeed, even the language has moved on. Virtualization, mobile edge computing and the Cloud, for example, were hardly common currency in 2006. Similarly, network densification, IoT and even 5G were viewed as longer-term concerns. Even old favourites like backhaul, Wi-Fi and last-mile solutions have evolved well beyond the versions we knew a decade ago.

We are only too aware that wireless technology has not stood still. And yet our fundamental mission hasn’t changed. We look at what our clients want. We examine what is out there or on the way in terms of technology, techniques and services. And we help our clients to save money and make cost-effective, future-proof investments.

Asked to position our offer, we can say Real Wireless bridges the gap between the wireless industry and wireless users. The technology evolves, the underlying architectures become more elaborate, the orchestration, installation, regulation and overall management of networks and systems become more demanding, but we help to make all of it work for our clients. That was true when we started and it’s still true today.

Of course, behind the simple concept of ‘making it work’ is no shortage of modelling tools, location-specific solutions and, of course expertise and commitment. We are focused solely on wireless and we are independent; we judge all wireless technologies and solutions on their merits and relevance to a given need. We can supply experts in everything from simulation modelling and mobile security to radio propagation and economic and regulatory issues. Small cells, cellular planning, spectrum policy, antennas, core networks… our experts can tackle all of these — and more. And we continually ensure that our pool of expertise is expanded to meet both change and growing demand.

Ensuring reliable wireless coverage for Wembley Stadium — one of our very first projects — illustrates this approach well. It’s not about installing a system and walking away. It’s about managing change. Over the past ten years, stadium coverage needs have given way to capacity requirements. Smartphone-equipped users are the norm, not the privileged few. Hardware and software need to be assessed as new options become available. Emergency services will soon move from TETRA to LTE. All of this has been managed without disrupting the smooth running of the client’s communications offering.

As it has over the past ten years, wireless communications will get even more complex as Real Wireless enters its second decade. But we will always aim to offer expertise and experience that can manage that complexity, never forgetting that the end goal will still be to do something very simple: to make wireless work for our clients.

Wi-Fi first? – William Webb, Regulatory and Spectrum Expert, Real Wireless

In developing wireless communications over the past three decades we have been chasing ever-faster speeds and ever higher capacity. This has delivered astonishing benefits for all of us that have truly transformed our lives. But the speed of data connection is now becoming less important than consistency – the ability to be connected at a reasonable speed everywhere. Rather than aiming for ever-faster connections it suggests that delivering enhanced coverage in a number of known problematic locations such as trains and rural areas would generate greater value for the economy and be preferred by most consumers. These problems have persisted throughout the broadband era but the technology and inclination to tackle them is now emerging.

In most of the locations where connectivity is difficult Wi-Fi is a better solution than cellular, with the exception of coverage in rural areas. Wi-Fi provision on trains enables more productive journeys. Wi-Fi in buildings increasingly enables voice calling as well as data access. Wi-Fi can also provide very high capacity in stadium and the 60GHz ‘Wi-Gig’ variant can enable Gbits/s links within rooms. This reflects a trend that has been underway for years towards increasing use and reliance on Wi-Fi to the extent that it is now the preferred method of communication for most. Our cellphones typically send around 85% of their data traffic over Wi-Fi and our tablets and laptops typically 100%. That we live in a ‘Wi-Fi first’ world is only slowly being realized across the industry – developing policies for such a world is becoming increasingly important for governments and regulators.

The end result – connectivity everywhere – would be one well worth striving for. A great road system is no longer one with unlimited maximum speed, but one with minimal congestion and excellent safety. A great communications system is one available everywhere, all the time with minimal congestion and at low cost. I am excited by the prospects that we might now be able to step off the ‘data rate’ escalator and focus on delivering a solution that meets everyone’s needs wherever they are.

One of my particular skills is in the regulation of radio spectrum and wireless communications – I spent seven years at Ofcom and have written two books on this topic. Our current regulatory framework devotes much attention to licensed spectrum for cellular and competition policies amongst mobile operators. It is time to reassess that framework, with increased focus on spectrum for Wi-Fi and with a changed competition policy that recognizes the world of mobile communications and the interests of the citizen-consumer will look quite different five years from now.

SON, your time has come – Julie Bradford, Managing Consultant

While self-organizing network (SON) technology might not inspire the same column inches as the hype surrounding 5G, for example, there are signs it’s finally starting to come back into the limelight.  In fact, I was recently part of a London conference wholly devoted to the subject, where a series of operator presentations left delegates in no doubt about the value and challenges of SON and automation both in today’s networks and on the path to 5G.

With 5G often described as a ‘network of networks’, such dense HetNets can be characterized as ‘multi-x environments’ – multi-technology, multi-domain, multi-spectrum, multi-operator and multi-vendor. As Small Cell Forum recently noted, these networks ‘must be able to automate the reconfiguration of [their] operation to deliver assured service quality across the entire network, and flexible enough to accommodate changing user needs, business goals and subscriber behaviours.’ And in networks comprising macrocells, large numbers of urban, enterprise and residential small cells, Wi-Fi access points, distributed radios and DAS antennas, it’s clear that optimization will be literally impossible without advanced SON at the heart of such automation.

But it’s not just the growing diversity of access mechanisms driving demand for sophisticated automation. The variety and complexity of services that are delivered by both network operators and over-the-top providers imply a huge range of customer experience expectations and network performance. Clearly, voice services over LTE are sensitive to packet loss, gamers struggle with latency, movies-on-the-go demand reliable buffering and so on; this is before the tsunami of 5G offerings ranging from augmented reality and the tactile internet, to sensor monitoring and first responder connectivity.

In addition, a number of conference speakers in London discussed virtualization and SDN in 5G networks.  Here there must surely be an opportunity for SON to help dynamically manage the ‘network slices’ of spectrum, sites, equipment, inter site transmissions etc. to deliver the right combination of services in the right place at the right time.   Many mentioned the idea of SON having to move from being re-active to pro-active as we move forwards on this path.

But in all this there is a danger that we are getting ahead of ourselves. At Real Wireless, part of our job is provide independent guidance around current investment decisions.  Many of the presenters at the conference were encouragingly operators who are actively using SON in their networks today.  However, much of the focus of real deployments was on automating radio planning and maintenance of sites which is still the tip of the iceberg in terms of what SON could achieve.  Also issues around interoperability, scalability and taking SON beyond the RAN appeared to remain a concern for operators, indicating that there is still plenty of work to be done to realize the full potential of SON.

Caroline Gabriel’s recent operator study concluded that automation and SON become entirely critical to the HetNet business case at a density level of about 10 cells per macro/50 cells per square km point, though SON was also considered highly desirable beyond three cells per macro/15 per square km. As network densification becomes more pressing, the case for reliable and interoperable SON will become increasingly urgent.

Virtual infrastructure, real value – Simon Fletcher, CTO, Real Wireless

The C in C-RAN is all about Centralisation, isn’t it? Well, not necessarily. When it more commonly stands for Cloud we can better understand how C-RAN can transform the value creation possibilities of wireless infrastructure, in ways that enable operators, in particular, to feel that their networks are more than just pipes.

This is an urgent consideration. Political and economic groupings (such as the EU) are predictably excited by tapping the potential of future communications services and its place in the evolving digital economy. This digital economy, in case we need reminding, is centred round things like – well, you name it: real-time data, delivery tracking, wearables, preventative healthcare, smart meters and the (potentially) vast savings they can produce and income they can generate.

The so-called eInfrastructure behind this super-smart, super-connected digital future is important; 5G should be part of this eInfrastructure. At the moment, the view of many political institutions seems to be that 5G is simply an incremental infrastructure play beyond today’s 4G and Wi-Fi. That is, it’s just more cost efficient connectivity and not much use if it isn’t transporting something of value – which is where true economic potential lies.

I would like to suggest a different view – that there is value in 5G infrastructure over and above its transport function. Explicitly positioning RAN as part of the Cloud business eco-system – where C-RAN means Cloud RAN – transforms 5G eInfrastructure into something that can add value in and of itself.

‘Cloudification’, then, brings new business models into the conceptual domain – but not just through new services. Cloud-RAN is a platform for creation of value within the pipe. With Cloud in play in the network and at the edge, new business innovations become obtainable. Such as mobile network multi-tenancy to support on-demand allocation of networking, storage and compute resources in a fully multi-tenant environment. Or multi-service- and context-aware adaptation of network functions to support a variety of services and corresponding QoE/QoS requirements.

Another way to put this is that dedicated networks contained in slices can meet the need of different services and tenants, be they service quality and performance, service-specific functionality, or adaptation to available infrastructure.

Potential new revenue drivers like these simply require innovative thinking and – as slicing and multi-tenancy imply – cooperation, which will be needed to open interfaces, enable control and user plane splits. It may also be necessary to embrace deferring capex for opex. Nevertheless, with a concerted change of mindset, there will be real intrinsic value in 5G infrastructure where there was – at least according to some people – none before.

Capitalizing on the indoor coverage opportunity – Oliver Bosshard, Managing Consultant

Something like 80% of mobile data traffic originates indoors. Contrast this with only 5% of RAN capex allocated to indoor coverage. At the same time, less than 2% of commercial and public buildings are currently covered by dedicated indoor solutions.

Unsurprisingly, in the vast majority of commercial buildings, mobile coverage remains weak or non-existent. This is clearly a challenge for both enterprises and operators, as many of the latter feel the business case for DAS or small cell deployment fails to stack up. Why should they invest more for diminishing returns? At the same time, most enterprises will argue it’s up to the carrier to provide reliable coverage and capacity inside and out.

From a carrier perspective, the problem is that, while mobile data usage continues to rise, ARPU growth rates have stalled and, in some markets, started to fall in absolute terms. The divergence of growing data consumption and diminishing ARPU is starkly reflected in network investment. MNOs in markets with low ARPU invest less in their network compared to markets with higher ARPU (e.g., the APRU in the US is more than double the ARPU of the UK).

But out in the world of enterprise, the natives are getting restless. For landlords and businesses, the need of good indoor connectivity is becoming increasingly urgent. Residential tenants see connectivity as essential as any other utility, and for most businesses ubiquitous connectivity is mission critical. Which is why many enterprises are willing if not always able to invest in their own infrastructure. There are plenty of examples of enterprises willing to pay for services that operators simply don’t have the processes or the sales team to deliver.

At Real Wireless, we have seen increasing interest in both venue-owned distributed antenna systems (DAS), and the use of small cells as dedicated indoor coverage solutions. From a technology perspective, small cells would appear well placed to solve the challenge of indoor coverage for most businesses. However, with the growing adoption of ‘bring your own device’ policies in the enterprise, multi-operator capability is also emerging as a crucial requirement. For many businesses, there’s no point installing a network that can only be used by subscribers associated one particular operator.

For larger-scale deployments, like stadiums, DAS remains the solution of choice. However, large DAS systems are expensive, and labor-intensive to deploy, requiring long installation periods and specialist expertise. Currently, the cost base makes DAS only suitable for very large premises such as stadiums, while its limitations in terms of cost elasticity and scalability mean its addressable market is unlikely to reach down into any but the largest companies or premises. Looking ahead a little, however, it’s worth noting that, with the advent of virtualization, the distinction between small cell and DAS technologies will become increasingly blurred.

So far, however, few mobile operators seem to have been enthusiastic about deploying small cells as a means of encouraging enterprise take up or reducing churn. This is partly because, in spite of the relative maturity of small cell technology, operators have been slow to incorporate them into their enterprise packages and many seem to believe that the business case does not stack up. There is undoubtedly an opportunity here for someone to come up with an innovative solution or a disruptive new approach to drive new revenues with indoor small cells. This, however, involves the recognition of new values chains and the elaboration of commonly understood commercial templates to distribute deployment costs across specific groups of stakeholders.

For example, when deploying a network to ensure coverage and capacity in a new shopping mall, it is clearly in the interests of the operator, the mall owner, the retailers and retail app firms to ensure ubiquitous coverage. So it’s clearly in the interests of all these businesses to share the costs of deployment. However, it’s equally true that the manner in which these costs are distributed is not something that should be reinvented for each and every shopping mall. This means abandoning outmoded business models, and more collaboration, partnership and revenue-sharing.

Ultimately indoor coverage is not something operators can afford to sideline for much longer. Absence of indoor coverage is already having a huge commercial impact and, like we have said, the enterprise (and consumers) are getting restless.
