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 most terrifying thing about Donald Trump's speech? What he didn't say

No politician uses official speeches to put across their most controversial ideas. But Donald Trump's are not hard to find. 

As Donald Trump took the podium on a cold Washington day to deliver his inauguration speech, the world held its breath. Viewers hunched over televisions or internet streaming services watched Trump mouth “thank you” to the camera, no doubt wondering how he could possibly live up to his deranged late-night Twitter persona. In newsrooms across America, reporters unsure when they might next get access to a president who seems to delight in denying them the right to ask questions got ready to parse his words for any clue as to what was to come. Some, deciding they couldn’t bear to watch, studiously busied themselves with other things.

But when the moment came, Trump’s speech was uncharacteristically professional – at least compared to his previous performances. The fractured, repetitive grammar that marks many of his off-the-cuff statements was missing, and so, too, were most of his most controversial policy ideas.

Trump told the crowd that his presidency would “determine the course of America, and the world, for many, many years to come” before expressing his gratefulness to President Barack Obama and Michelle Obama for their “gracious aid” during the transition. “They have been magnificent," Trump said, before leading applause of thanks from the crowd.

If this opening was innocent enough, however, it all changed in the next breath. The new president moved quickly to the “historic movement”, “the likes of which the world has never seen before”, that elected him President. Following the small-state rhetoric of his campaign, Trump promised to take power from the “establishment” and restore it to the American people. “This moment," he told them, “Is your moment. It belongs to you.”

A good deal of the speech was given over to re-iterating his nationalist positions while also making repeated references to the key issues – “Islamic terrorism” and families – that remain points of commonality within the fractured Republican GOP.

The loss of business to overseas producers was blamed for “destroying our jobs”. “Protection," Trump said, “Will lead to great strength." He promised to end what he called the “American carnage” caused by drugs and crime.

“From this day forward," Trump said, “It’s going to be only America first."

There was plenty in the speech, then, that should worry viewers, particularly if you read Trump’s promises to make America “unstoppable” so it can “win” again in light of his recent tweets about China

But it was the things Trump didn't mention that should worry us most. Trump, we know, doesn’t use official channels to communicate his most troubling ideas. From bizarre television interviews to his upsetting and offensive rallies and, of course, the infamous tweets, the new President is inclined to fling his thoughts into the world as and when he sees fit, not on the occasions when he’s required to address the nation (see, also, his anodyne acceptance speech).

It’s important to remember that Trump’s administration wins when it makes itself seem as innocent as possible. During the speech, I was reminded of my colleague Helen Lewis’ recent thoughts on the “gaslighter-in-chief”, reflecting on Trump’s lying claim that he never mocked a disabled reporter. “Now we can see," she wrote, “A false narrative being built in real time, tweet by tweet."

Saying things that are untrue isn’t the only way of lying – it is also possible to lie by omission.

There has been much discussion as to whether Trump will soften after he becomes president. All the things this speech did not mention were designed to keep us guessing about many of the President’s most controversial promises.

Trump did not mention his proposed ban on Muslims entering the US, nor the wall he insists he will erect between America and Mexico (which he maintains the latter will pay for). He maintained a polite coolness towards the former President and avoiding any discussion of alleged cuts to anti-domestic violence programs and abortion regulations. Why? Trump wanted to leave viewers unsure as to whether he actually intends to carry through on his election rhetoric.

To understand what Trump is capable of, therefore, it is best not to look to his speeches on a global stage, but to the promises he makes to his allies. So when the President’s personal website still insists he will build a wall, end catch-and-release, suspend immigration from “terror-prone regions” “where adequate screening cannot occur”; when, despite saying he understands only 3 per cent of Planned Parenthood services relate to abortion and that “millions” of women are helped by their cancer screening, he plans to defund Planned Parenthood; when the president says he will remove gun-free zones around schools “on his first day” - believe him.
