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.

Why it's a mistake to assume that Jeremy Corbyn has already won

The shadow chief secretary to the Treasury on why the race to be Labour's leader is far from over.

They think it’s all over.

But they’re wrong.

The fat lady has yet to sing.

The commentary and reporting around the Labour party leadership campaign has started to assume we have a winner already in Jeremy Corbyn. The analysis, conjecture, predictions/complete guesswork about what happens next has begun in earnest. So we have seen speculation about who will be appointed to a Corbyn shadow cabinet, and “meet the team” pieces about Jeremy’s backroom operation.

Which is all very interesting and makes for the usual Westminster knockabout of who might be up and who might be going in the other direction pdq...

But I think it’s a mistake to say that Jeremy has already won.

Because I hear that tens of thousands of Labour party members, affiliates and registered supporters are yet to receive their ballot papers. And I am one of them. I can’t remember the last time I checked my post quite so religiously! But alas, my papers are yet to arrive.

This worries me a bit about the process. But mostly (assuming all the remaining ballots finally land in enough time to let us all vote) it tells me that frankly it’s still game on as far as the battle to become the next leader of the Labour party is concerned.

And this is reinforced when we consider the tens of thousands who have apparently received their papers but who have yet to vote. At every event I have attended in the last couple of weeks, and in at least half of all conversations I have had with members across the country, members are still making their minds up.

This is why we have to continue fighting for every vote until the end – and I will be fighting to get out every vote I possibly can for Yvette Cooper.

Over the campaign, Yvette has shown that she has a clear vision of the kind of Britain that she wants to see.

A Britain that tackles head-on the challenges of globalisation. Instead of the low-wage low-skill cul-de-sac being crafted by the Tories, Yvette's vision is for 2m more high skill manufacturing jobs. To support families she will prioritise a modern childcare system with 30 hours of fully funded child care for all 3 and 4 year olds and she will revive the bravery of post war governments to make sure 2m more homes are built within ten years.

It's an optimistic vision which taps into what most people in this country want. A job and a home.

And the responses of the focus groups on Newsnight a few days ago were telling – Yvette is clearly best placed to take us on the long journey to the 2020 general election by winning back former Labour voters.

We will not win an election without winning these groups back – and we will have to move some people who were in the blue column this time, to the red one next time. There is no other way to do it – and Yvette is the only person who can grow our party outwards so that once again we can build a winning coalition of voters across the country.
