Network providers have overestimated the willingness of local authorities and building owners to provide the planning permission required to install antennas on lampposts and buildings. Without antenna density, FWA isn’t a viable, scalable option for business connectivity; at best, companies will have to wait three years or more before 5G offers a viable wireless leased line alternative. At the time of writing, Three UK has just launched their FWA offering in a few postcode areas in London for home broadband, and already there are accounts of intermittent signal problems impacting performance, which lends weight to the argument for greater antenna density being required to achieve stable, repeatable service coverage. At worst, of course, the continuing concerns regarding the potential health implications of 5G networks could further delay installation. Local authorities will remain wary about exposing the public to risk; unless and until the 5G industry can address in a concerted, focused way that the persistent claims that running high-frequency networks in high-density areas isn’t a risk, planners may meet resistance from schools, hospitals, community and other building managers. There are other shortcomings. 5G services today don’t include any service level agreements, undermining any business confidence in the quality and repeatability of the service. There seems to be no network slicing (the technique to separate traffic types), making it impossible to prioritise network traffic such as IoT. Indeed, the entire IoT aspect of 5G has been shelved for now, with both EE and Vodafone confirming that IoT will not be part of the initial service. There’s no clarity regarding support for IoT devices in the future; the ability to upgrade or migrate from current to 5G networks or any commercial information that would help both managed service providers and businesses build 5G into their future IoT strategies. Use what we have already So, what are the options? 5G is disappointing, but N G S I N C E /CANNONT4 Micro & Mini Data Centres in 13 companies cannot afford to postpone much-needed network investments in wireless primary and backup services indefinitely. The good news is that 4G networks are now mature – and that means both widely available and reliable. The arrival of 5G will address the burgeoning capacity issue for 4G, which is great news; and recent market price adjustments have taken 4G out of the last resort category and made it into a viable option for primary and resilience connectivity. 4G is proven to support VoIP and unified communication streaming; it can also be used for machine to machine communication. Software defined networking (SDN) enables 4G to be blended with other networks to deliver primary connections that deliver a reliable and affordable leased line alternative. Furthermore, IoT is deliverable today using the unlicensed spectrum and other standards, including Narrowband IoT and LoRaWAN to enable mass IoT deployments, which will be incorporated later into the emerging 5G standard, future-proofing investment. Critically, all these services come with SLAs; networks are reliable and accessible. Essentially, it’s possible today to meet business needs for affordable and consistent primary and secondary connectivity services with the existing 4G network infrastructure. Delivering connectivity 5G technology looks good on paper and there have been significant deployments in the US and other countries. But there remains a number of significant infrastructure challenges that continue to undermine 5G value and impact on our business landscape in the short to medium term. As the 5G network plans and service offerings stand today, businesses will struggle to justify investment in the new technology. However, while waiting for the promise of 5G to be realised, businesses can extract significant value from 4G today. And with further price disruption expected within the 4G market, the cost model will become ever more compelling, for primary, secondary and IoT connectivity.n 1 9 7 8 /CANNONTECHNOLOGIES Modular D a ta C e n t re s Data Centre Design, Build & Construction UR LATEST BROCHURES : [email protected] TOMISING STANDARDS | AWARD WINNING DCiM Monitoring & Control +44 (0) 1425 632600
