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.

The public like radical policies, but they aren't so keen on radical politicians

Around the world, support for genuinely revolutionary ideas is strong, but in the UK at least, there's less enthusiasm for the people promising them.

You’re probably a getting a little bored of the litany of talking head statistics: trust in elected officials, parliament, the justice system and even democracy itself has been falling steadily for years and is at record lows. Maybe you’ve seen that graph that shows how people born after 1980 are significantly less likely than those born in 1960 to think that living in a democracy is ‘essential’. You’ve possibly heard of the ‘Pasokification’ of the centre-left, so-named the collapse of the once dominant Greek social democratic party Pasok, a technique being aggressively pursued by other centre-left parties in Europe to great effect.    

And so, goes the logic, there is a great appetite for something different, something new. It’s true! The space into which Trump et al barged leaves plenty of room for others: Beppe Grillo in Italy, Spanish Podemos, Bernie Sanders, Jean Luc Melanchon, and many more to come.

In my new book Radicals I followed movements and ideas that in many cases make someone like Jeremy Corbyn seem positively pedestrian: people who want to dismantle the nation state entirely, use technology to live forever, go off grid. All these ideas are finding fertile ground with the frustrated, disillusioned, and idealistic. The challenges of coming down the line – forces of climate change, technological change, fiscal crunch, mass movements of people – will demand new types of political ideas. Radical, outsider thinking is back, and this does, in theory at least, offer a chink of light for Corbyn’s Labour.

Polling last week found pretty surprising levels of support for many of his ideas. A big tax on high earners, nationalising the railways, banning zero hours contracts and upping the minimum wage are all popular. Support for renewable energy is at an all-time high. According to a recent YouGov poll, Brits actually prefer socialism to capitalism, a sentiment most strongly held among younger people.

There are others ideas too, which Corbyn is probably less likely to go for. Stopping benefits entirely for people who refuse to accept an offer of employment is hugely popular, and in one recent poll over half of respondents would be happy with a total ban on all immigration for the next two years. Around half the public now consistently want marijuana legalised, a number that will surely swell as US states with licenced pot vendors start showing off their dazzling tax returns.

The BNP effect used to refer to the problem the far-right had with selling their ideas. Some of their policies were extremely popular with the public, until associated with the BNP. It seems as though the same problem is now afflicting the Labour brand. It’s not the radical ideas – there is now a genuine appetite for those who think differently – that’s the problem, it’s the person who’s tasked with delivering them, and not enough people think Corbyn can or should. The ideal politician for the UK today is quite possibly someone who is bold enough to have genuinely radical proposals and ideas, and yet appears extremely moderate, sensible and centrist in character and temperament. Perhaps some blend of Blair and Corbyn. Sounds like an oxymoron doesn’t it? But this is politics, 2017. Anything is possible.
