Roundup After years of interminable waffle, 5G is almost upon us, and Huawei wants to tell us what works – and what must wait. At this stage, the wrinkles are as valuable as the milestones, because 5G is a vast smorgasbord of different technologies and aspirations.
At Huawei's Mobile Broadband Forum (MBBF), Huawei deputy chairman and rotating CEO Ken Hu** said that 154 carriers in 66 countries are testing 5G, and Huawei itself has shipped 10,000 5G basestations.
But Huawei doesn't expect 5G smartphones to reach decent volumes until 2021. That's necessary for the mass market to take off.
Also at MBBF, BT demonstrated a 5G broadcast "Live from Wembley", inspiring one attendee to reminisce about how we'd all be using video calls once 3G fell into place.
BT Sport is experimenting with 5G for remote production in the field and made this bold claim last week. It said it hopes to "transmit live using only fibre technology and a rucksack containing a 5G Wi-Fi router which will reduce broadcasting costs and allow highlights programmes like Match of the Day to be aired at tea-time rather than late evening".
This invites you to think that the reason for MotD starting five hours after most games finish on a Saturday is because of network issues, rather than club policy, or the time needed to produce a professionally curated and edited highlights show.
Nevertheless, BT hopes 5G broadcasts can kick off in 2019/20.
Orange came with some well-justified whinges. Since 5G is all things to all people, it's really a bunch of different technologies and architectures.
Orange's presentation ranged from 5G as a "complement" to wired broadband (5G-FWA, which we discussed yesterday) and ranged over specialist services. Thanks to network slicing, real QoS may be here at last. Orange said tests on vehicle-to-vehicle or vehicle-to-infrastructure networks (V2X) could attain a latency as low as 15ms.
There's a demo from March here.
Aston Martin was on hand to plug its luxury Lagonda concept, which if it ever comes to fruition, will be an all-electric, "ready for autonomous driving" car. What does this mean? The steering wheel is retractable. Right now safe autonomous driving is at Step 2 in the Underpant Gnomes'*** business plan.
An attempt at self-deprecating industry humour came here, which rather highlighted the obstacles to 5G which everyone recognises.
So what's in the way of all this greatness? The handsets aren't here – they traditionally lag behind – although a bunch will be unveiled at MWC early next year. Including, according to the Wall Street Journal, Samsung's Galaxy 10.
Then there are deployment issues, highlighted by Huawei's Ryan Ding. Getting 5G into lots of new sites (and it will require many more sites than 4G) remains difficult. The spectrum isn't available – a common complaint.
Three CEO David Dyson echoed these complaints. The UK is 19x more expensive to acquire sites than the Nordic countries, and the passive infrastructure 4x more expensive. It makes transmission 6x as expensive as Austria, Sweden and Denmark.
That's defined by the ECC regulations – but with Ofcom having just signed off on a multiyear review, it's unlikely to want to revisit it without political pressure. ®

** This refers to the fact Huawei appoints three alternating CEOs who job share, rather than his manner.
*** For those unfamiliar with the South Park episode, the gnomes' plan went like this. Step 1: Collect underpants. Step 2: ? Step 3: Profit.
