Network convergence: How to deliver a seamless experience

Operators need to adapt to the changing connectivity demands post-COVID19

The global dependency on consistent high-performance connectivity has recently come to the fore as the COVID-19 outbreak has transformed many of the remaining non-digital tasks into online activities.

The typical patterns of networking have broken and a ‘new normal’, albeit possibly a somewhat transitory one, is emerging. The recovery of the global economy will depend on governments, healthcare providers, businesses and their employees robustly communicating and gaining uninhibited access to content and cloud through their service providers – at any time of day, from any location and on any device.

Reliable connectivity is a critical commodity. Network usage patterns have shifted more towards the home and remote working. Locations which were previously light-usage now have high demands. Conversely, many business locations no longer need such high capacity. Utilisation is not expected to return to pre-COVID-19 patterns either, as people and businesses adapt to new daily routines – at least for some time.

The strategies with which telcos started the year have of course been disrupted with resources diverted away from strategic objectives to deal with a new mandate – keep the country connected. In the short-term, the focus has shifted to one which is more tactical – ensuring customer satisfaction through a reliable and adaptable service with rapid response to issues. In the long-term, however, the objectives for capacity and coverage remain. Telcos are still required to reach national targets for a minimum connection quality in rural areas, whilst delivering high bandwidth service demands in hotspot locations (although these hotspot locations might now change).

Of course, modern networks are designed with scalability and adaptability in mind – some recent deployments from new disruptors (such as Rakuten) demonstrate the power of virtualisation and automation in that process, particularly when it comes to the radio access network (RAN). In many legacy networks, however, one area which is not able to adapt fast enough is the physical access. Limits on spectrum, coverage (indoors and outdoors) and the speed at which physical infrastructure can be installed or updated become a bottleneck in the adaptation process. New initiatives to meet home working demand through an accelerated fibre rollout are happening, but they tend to come at great cost.

Network convergence is a concept which can provide a quick and convenient way to address this need for improved coverage, speed and reliability in the access network, without the need to install or upgrade last mile infrastructure. By definition, it is the coming-together of multiple network assets, as part of a transformation to one intelligent network which can efficiently provide customers with a single, unified, high-quality experience at any time, in any place.

It has already attracted interest and is finding an initial following. A few telcos have used it to provide better home broadband. Internet content and cloud service providers are interested, as it adds resilience to the mobile user experience, and enterprises are interested in utilising multiple lower cost commodity backhauls – the combination of which benefits from inherent protection against costly network outages.

Network convergence helps create an adaptable and resilient last mile

Most telcos already have the facility to connect with their customers via multiple means; providing mobile, fixed line and public Wi-Fi connectivity to those in their coverage footprint. The strategy has been to convert individual ‘pure’ mobile or fixed customers into households. The expectation is that this creates revenue increase through bundling and loyalty whilst bringing some added friction into the ability to churn – a concept which has been termed ‘convergence’. Although the customer may see one converged telco through brand, billing and customer support, the delivery of a consistent user experience across all modes of network access has been lacking and awkward. In the end, it is customer dissatisfaction which drives churn, so delivering a consistent user experience is important.

Convergence is a term used to mean many different things, from a single bill for all household connectivity, to modernising multiple core networks into a single efficient core. While most telcos have so far been concentrating on increasing operational efficiency, increasing customer loyalty/NPS and decreasing churn through some initial aspects of convergence, some are now looking into network convergence – where multiple access technologies (4G, 5G, Wi-Fi, fixed line) can be used together to deliver a resilient, optimised and consistent network quality and coverage.

Overview of convergence

As an overarching concept, network convergence introduces more flexibility into the access layer. It allows a single converged core network to utilise and aggregate whichever last mile connectivity options are most suited to the environment. Some examples are:

  • Hybrid Access: DSL and 4G macro network used together to provide extra speed and fallback reliability in hybrid fixed/mobile home gateways.
  • Cell Densification: 5G and Wi-Fi small cells jointly providing short range capacity to augment the macro network in dense urban areas.
  • Fixed Wireless Access: using cellular as a fibre alternative in challenging areas.

The ability to combine various network accesses is attractive as an option for improving adaptability, resilience and speed. Strategically, putting such flexibility in place can support future growth and customer retention with the added advantage of improving operational efficiency. Tactically, it enables an ability to quickly adapt resources to short-term changes in demand. COVID-19 has been a clear example of this need.

5G: Why Verizon thinks differently – and what to do about it

Introduction

Verizon’s path

Verizon is deploying 5G as quickly as it practically can, already planning to have over 1,000 base stations by the end of 2018. CEO Lowell McAdam told investors he wants to quickly reach 30 million homes, while Goldman Sachs estimated Verizon planned to spend US$20 billion for this initial phase to 2021/22 – although there is no publicised schedule. Verizon’s investments include the acquisition of XO Communications for US$1.8 billion, which has fibre in 45 of the 50 largest cities, which Verizon sees as vital infrastructure for its 5G build.

The base stations will support mobile 5G as soon as the handsets are ready. Leading mobile chip vendor Qualcomm expects a limited number of mobile phone chips to be available by the end of 2018. Sufficient chips for phones in volume are expected by mid-year 2019.[1] Taiwan’s MediaTek, the number two 4G chipmaker, says it will “hit the 5G chip market with a bang in 2019”.[2]

Verizon is building a state-of-the-art network in 800MHz of spectrum at 28GHz using existing towers and new small cells, delivering a peak speed of 10 gigabits per second or lower. A consumer in a good location should get a true gigabit in both directions, with mobile network latency of between 5 ms and 20 ms.[3]

This will probably be the largest fast 5G network built before the next decade. The Chinese operators will mostly be using frequencies below 6GHz, which will be 65% to 85% slower.

Verizon’s large fixed opportunity

In two-thirds of the US, Verizon sells wireless but is not the incumbent wireline carrier. With limited unbundling at present, it cannot offer a landline (or equivalent) service to over 70 million of its wireless customers. It therefore cannot offer quadruple play for higher revenue, lower churn and better margins.

Yet in half the US, there is only one choice for decent broadband: the cable company. Over half of US cable has been upgraded to gigabit download speeds, and over three-quarters of the country will be offered gigabit cable by the end of 2019.[4] Faster speeds contributed to the 2.7 million broadband subscriptions cable added in 2017.

In many places, the telephone companies have not upgraded decade-old DSL lines and are not competitive with their cable counterparts.  In 2017, US telephone companies lost 625,000 broadband subscriptions.

McAdam expects to quickly win 10– 20% of the new market Verizon can address. Dean Bubley notes it is very difficult to persuade reasonably happy customers to switch, but cable service in the US is notoriously bad. Verizon’s long-term goal is 40– 50%, consistent with its results where it has FIOS fibre to the home. CFO Matt Ellis believes, “When you look at other cities outside of the ILEC footprint, offering consumer services using 5G is, we think, going to have a lot of upside for the company.”[5]
