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.

An unmatched font of knowledge

Edinburgh’s global reputation as a knowledge economy is rooted in the performance and international outlook of its four universities.

As sociologist-turned US Senator Daniel Patrick Moynihan recognised when asked how to create a world-class city, a strong academic offering is pivotal to any forward-looking, ambitious city. “Build a university,” he said, “and wait 200 years.” He recognised the long-term return such an investment can deliver; how a renowned academic institution can help attract the world. However, in today’s increasingly globalised higher education sector, world-class universities no longer rely on the world coming to come to them – their outlook is increasingly international.

Boasting four world-class universities, Edinburgh not only attracts and retains students from around the world, but also increasingly exports its own distinctively Scottish brand of academic excellence. In fact, 53.9% of the city’s working age population is educated to degree level.

In the most recent QS World University Rankings, the University of Edinburgh was named as the 21st best university in the world, reflecting its reputation for research and teaching. It’s a fact reflected in the latest UK Research Exercise Framework (REF), conducted in 2014, which judged 96% of its academic departments to be producing world-leading research.

Innovation engine

Measured across the UK, annual Gross Value Added (GVA) by University of Edinburgh start-ups contributes more than £164m to the UK economy. In fact, of 262 companies to emerge from the university since the 1960s, 81% remain active today, employing more than 2,700 staff globally. That performance places the University of Edinburgh ahead of institutions such as MIT in terms of the number of start-ups it generates; an innovation hothouse that underlines why one in four graduates remain in Edinburgh and why blue chip brands such as Amazon, IBM and Microsoft all have R&D facilities in the city.

One such spin out making its mark is PureLiFi, founded by Professor Harald Haas to commercialise his groundbreaking research on data transmission using the visible light spectrum. With data transfer speeds 10,000 times faster than radio waves, LiFi not only enables bandwidths of 1 Gigabit/sec but is also far more secure.

Edinburgh’s universities play a pivotal role in the local economy. Through its core operations, knowledge transfer activities and world-class research the University generated £4.9bn in GVA and 44,500 jobs globally, when accounting for international alumni.

With £1.4bn earmarked for estate development over the next 10 years, the University of Edinburgh remains the city’s largest property developer. Its extensive programme of investment includes the soon-to-open Higgs Centre for Innovation. A partnership with the UK Astronomy Technology Centre, the new centre will open next year and will supply business incubation support for potential big data and space technology applications, enabling start-ups to realise the commercial potential of applied research in subjects such as particle physics.

It’s a story of innovation that is mirrored across Edinburgh’s academic landscape. Each university has carved its own areas of academic excellence and research expertise, such as the University of Edinburgh’s renowned School of Informatics, ranked among the world’s elite institutions for Computer Science. 

The future of energy

Research conducted into the economic impact of Heriot-Watt University demonstrated that it generates £278m in annual GVA for the Scottish economy and directly supports more than 6,000 jobs.

Set in 380-acres of picturesque parkland, Heriot-Watt University incorporates the Edinburgh Research Park, the first science park of its kind in the UK and now home to more than 40 companies.

Consistently ranked in the top 25% of UK universities, Heriot-Watt University enjoys an increasingly international reputation underpinned by a strong track record in research. 82% of the institution’s research is considered world-class (REF) – a fact reflected in a record breaking year for the university, attracting £40.6m in research funding in 2015. With an expanding campus in Dubai and last year’s opening of a £35m campus in Malaysia, Heriot-Watt is now among the UK’s top five universities in terms of international presence and numbers of international students.

"In 2015, Heriot-Watt University was ranked 34th overall in the QS ‘Top 50 under 50’ world rankings." 

Its established strengths in industry-related research will be further boosted with the imminent opening of the £20m Lyell Centre. It will become the Scottish headquarters of the British Geological Survey, and research will focus on global issues such as energy supply, environmental impact and climate change. As well as providing laboratory facilities, the new centre will feature a 50,000 litre climate change research aquarium, the UK Natural Environment Research Council Centre for Doctoral Training (CDT) in Oil and Gas, and the Shell Centre for Exploration Geoscience.

International appeal

An increasingly global outlook, supported by a bold international strategy, is helping to drive Edinburgh Napier University’s growth. The university now has more than 4,500 students studying its overseas programmes, through partnerships with institutions in Hong Kong, Singapore, China, Sri Lanka and India.

Edinburgh Napier has been present in Hong Kong for more than 20 years and its impact grows year-on-year. Already the UK’s largest higher education provider in the territory, more than 1,500 students graduated in 2015 alone.

In terms of world-leading research, Edinburgh Napier continues to make its mark, with the REF judging 54% of its research to be either world-class or internationally excellent in 2014. The assessment singled out particular strengths in Earth Systems and Environmental Sciences, where it was rated the top UK modern university for research impact. Taking into account research, knowledge exchange, as well as student and staff spending, Edinburgh Napier University generates in excess of £201.9m GVA and supports 2,897 jobs in the city economy.

On the south-east side of Edinburgh, Queen Margaret University is Scotland’s first university to have an on-campus Business Gateway, highlighting the emphasis placed on business creation and innovation.

QMU moved up 49 places overall in the 2014 REF, taking it to 80th place in The Times’ rankings for research excellence in the UK. The Framework scored 58% of Queen Margaret’s research as either world-leading or internationally excellent, especially in relation to Speech and Language Sciences, where the University is ranked 2nd in the UK.

In terms of its international appeal, one in five of Queen Margaret’s students now comes from outside the EU, and it is also expanding its overseas programme offer, which already sees courses delivered in Greece, India, Nepal, Saudi Arabia and Singapore.

With 820 years of collective academic excellence to export to the world, Edinburgh enjoys a truly privileged position in the evolving story of academic globalisation and the commercialisation of world-class research and innovation. If he were still around today, Senator Moynihan would no doubt agree – a world-class city indeed.
