10 OPINION Too little  too soon By Nick Sacke, Head of Products and IoT, Comms365 www.comms365.com The UK 5G launch season is in full swing, but it's a shadow of what's needed – 4G still reigns supreme 5G has arrived – or has it? At the time of writing, EE, Vodafone and Three have announced the availability of the UK’s first 5G networks, and O2 has announced launch plans. The new services are surprisingly limited in geographic coverage, performance and features, focusing on broadband-only applications. The massive IoT connectivity application of the services has been delayed to 2023. The current incarnation in all carriers, except Three UK, doesn’t offer the promised alternative to replace leased lines (millimetre wave). Even the much-hyped mobile broadband speeds have been downgraded from gigabits to burst rates in the hundreds of MB/s at best. Add in the lack of reliability, spotty coverage and inconsistency in commercial approach, and 5G is no more than a work in progress. With a significant number of infrastructural and operational challenges to be overcome before 5G can become a business reality for UK companies, it’s time to set the glass half empty promises of 5G to one side and leverage the proven quality, consistency and reliability of existing wireless networks, especially 4G, to support business communications infrastructure and growth. Land grab The promise of 5G has been compelling for many reasons; from businesses looking to achieve widespread IoT deployments, to those seeking a viable broadband and leased line replacement alternative or companies struggling in areas of rural connectivity deprivation, on paper 5G appears to have all the answers. The recent 5G rollout announcements, however, have been something of a disappointment for all. Limited to just six cities initially (EE), and with variable accessibility even within these areas, the 5G rollout is a promise rather than a reality. It will take several years before 5G offers ubiquitous accessibility – and there are no firm plans to support rural areas and manufacturing – rather, a set of innovation challenges that are funding Consortia projects to look at innovation to address the problem. Even then a number of key features of the service are still to be clarified. The reality today is that 5G, where it’s available, is providing enhanced mobile broadband and no more. For those with compatible devices, an issue in itself given the lack of available devices and the Huawei situation, 5G will enable voice calls and broadband internet access. Even then, the promised speeds are not being delivered. Customers can expect 150-200Mbps at best, and on the Vodafone commercial plans we see guarantees of 2Mbps, www.networkseuropemagazine.com
