4G's so last year: why we need 5G, and now

We have a spectrum crunch on our hands, and technology is only just starting to deal with that.

By current trends, data traffic is expected to increase 1,000 fold by 2020, by which time there will be an estimated at least 50 billion Internet-capable devices. Our ever-growing love for mobile comms is a fast lane to "spectrum crunch" – we're just running out of radio space.

The electromagnetic spectrum of radiowaves is another of our finite resources, shared out between a hungry media still expanding its TV and radio platforms, all the mobile web-enabled devices, emergency services and the military. With such scarcity, Government control is needed to allocate elements of the spectrum. Of course, that also pretends an opportunity to make large sums from the private sector (£22.5bn from the 3G auction when the industry was at a peak of optimism in 2000, and still a further £3.5bn expected, and budgeted into the autumn statement, from the imminent 4G auction).

Spectrum crunch will basically mean a shortage of supply, leading to a widening gap between the technology "haves" and "have nots", smaller markets for businesses and restrictions on the development of wireless-enabled technologies, products and services. Instead of the great opening up of the web, mass participation and new commercial opportunities, we'll see a closing down.

This is why 5G is so important, even before 4G has taken off. Unlike its predecessors, 5G technology isn't about improving speed of data rates, it's about sustainability and making a global digital life a possibility. 5G is needed urgently as a new basis of an efficient, space-saving approach to the spectrum. It will also be the technology that helps minimise the energy requirements of web devices and network infrastructure – another issue as everyday life becomes increasingly mobile and digital.

Although the UK played an active role in the creation of 2G (GSM) cellular standards, we have increasingly fallen behind in the succeeding generations of 3G and 4G standards. 5G is a huge opportunity for the UK to regain a world leading position and to be at the heart of new business creation and product development around the technologies with rich applications. It's already starting to happen. The University of Surrey has been given the go-ahead to set up a 5G Innovation Centre, backed up by a total of £35m investment from a combination of the UK Research Partnership Investment Fund and a consortium of key mobile operators and infrastructure providers including Huawei, Samsung, Telefonica Europe, Fujitsu Laboratories Europe, Rohde & Schwarz and AIRCOM International.

So the 5G Innovation Centre will be a hub for the latest research and technologies, capable of attracting telecoms giants internationally to carry out their own R&D and the basis of a cluster for the involvement of all kinds of businesses from different sectors interested in getting a lead from taking advantage of 5G platforms: media firms, gaming, health, logistics etc. The Centre will live within a 5G testing environment (operating throughout the University campus and also into Guildford in order to offer a model of the different types of urban and non-urban spaces) for firms to try out new offerings on the latest network.

What matters now is that UK organisations are long-sighted enough to seize the opportunity and get involved. The major investment funds mean we have a window in which to set the pace for what may well be the the make or break phase in the history of mobile communications. We have a long history in the UK of quality research that doesn't lead to commercialisation by home firms but picked up overseas. And with every economy now looking for the next big thing, the new technologies and markets that will shore up deficits and be an engine of long-term growth, 5G has the potential to be a precious commodity of the coming years.

If the SNP truly want another referendum, the clock is ticking

At party conference in Glasgow, I heard Scotland’s governing party demand a future distinctly different from the one being sketched out in Westminster. 

Nicola Sturgeon described Glasgow as the “dear green city” in her opening address to the SNP party conference, which may surprise anyone raised on a diet of Ken Loach films. In fact, if you’re a fan of faded grandeur and nostalgic parks, there are few places to beat it. My morning walk to conference took me past chipped sandstone tenements, over a bridge across the mysterious, twisting River Kelvin, and through a long avenue of autumnal trees in Kelvingrove Park. In the evenings, the skyline bristled with Victorian Gothic university buildings and church spires, and the hipster bars turned on their lights.

In between these two walks, I heard Scotland’s governing party demand a future distinctly different from the one being sketched out in Westminster. Glasgow’s claim to being the UK’s second city expired long ago but I wonder if, post-Brexit, there might be a case for reviving it.



Scottish politics may never have looked more interesting, but at least one Glasgow taxi driver is already over it. All he hears in the back of his cab is “politics, fitba and religion”, he complained when he picked me up from the station. The message didn’t seem to have reached SNP delegates at the conference centre on the Clyde, who cheered any mention of another referendum.

The First Minister, though, seems to have sensed the nation’s weariness. Support for independence has fallen from 47 per cent in June (Survation) to 39 per cent in October (BMG Research). Sturgeon made headlines with the announcement of a draft referendum bill, but read her speeches carefully and nothing is off the table. SNP politicians made the same demands again and again – devolved control of immigration and access to the single market. None ruled out these happening while remaining in the UK.

If Sturgeon does want a soft Brexit deal, though, she must secure it fast. Most experts agree that it would be far easier for an independent Scotland to inherit Britain’s EU membership than for it to reapply. Once Article 50 is triggered, the SNP will be in a race against the clock.


The hare and the tortoise

If anyone is still in doubt about the SNP’s position, look who won the deputy leadership race. Angus Robertson, the gradualist leader of the party in the Commons, saw off a referendum-minded challenger, Tommy Sheppard, with 52.5 per cent of the vote.

Conference would be nothing without an independence rally, and on the final day supporters gathered for one outside. A stall sold “Indyref 2” T-shirts but the grass-roots members I spoke to were patient, at least for now. William Prowse, resplendent in a kilt and a waistcoat covered in pro-indy
badges, remains supportive of Sturgeon. “The reason she has not called an Indy 2 vote
is we need to have the right numbers,” he told me. “She’s playing the right game.”

Jordi McArthur, a member for 30 years, stood nearby waving a flagpole with the Scottish, Welsh and Catalan flags side by side. “We’re happy to wait until we know what is happening with Brexit,” he said. “But at the same time, we want a referendum. It won’t be Nicola’s choice. It will be the grass roots’ choice.”


No Gerrymandering

Party leaders may come and go, but SNP members can rely on one thing at conference – the stage invasions of the pensioner Gerry Fisher. A legendary dissenter, Fisher refused this year to play along with the party’s embrace of the EU. Clutching the
lectern stubbornly, he told members: “Don’t tell me that you can be independent and a member of the EU. It’s factually rubbish.” In the press room, where conference proceedings were shown unrelentingly on a big screen, hacks stopped what they were doing to cheer him on.


Back to black

No SNP conference would be complete without a glimpse of Mhairi Black, the straight-talking slayer of Douglas Alexander and Westminster’s Baby of the House. She is a celebrity among my millennial friends – a video of her maiden Commons speech has been watched more than 700,000 times – and her relative silence in recent months is making them anxious.

I was determined to track her down, so I set my alarm for an unearthly hour and joined a queue of middle-aged women at an early-morning fringe event. The SNP has taken up the cause of the Waspi (Women Against State Pension Inequality) campaign, run by a group of women born in the 1950s whose retirement age has been delayed and are demanding compensation. Black, who is 22, has become their most ­articulate spokeswoman.

The event started but her chair remained unfilled. When she did arrive, halfway through the session, it was straight from the airport. She gave a rip-roaring speech that momentarily convinced even Waspi sceptics like me, and then dashed off to her next appointment.


Family stories

Woven through the SNP conference was an argument about the benefits of immigration (currently controlled by Westminster). This culminated in an appearance by the Brain family, whose attempt to resist deportation back to Australia has made them a national cause célèbre. (Their young son has learned to speak Gaelic.) Yet for me, the most emotional moment of the conference was when another family, the Chhokars, stepped on stage. Surjit Singh Chhokar was murdered in 1998, but it took 17 years of campaigning and a change in double jeopardy laws before his killer could be brought to justice.

As Aamer Anwar, the family’s solicitor, told the story of “Scotland’s Stephen Lawrence”, Chhokar’s mother and sister stood listening silently, still stricken with grief. After he finished, the delegates gave the family a standing ovation.
