What is 5G and when will it be unveiled in the UK?

5G Innovation Centre

The University of Surrey’s 5G Innovation Centre is home to the pioneers of wireless technology who have been researching the next generation of connectivity since 2012, before 4G even hit the scene. Led by Professor Rahim Tafazolli, the centre is working alongside telecom juggernauts to usher in what has been christened the “Internet of Things”, which will see the network capable of things that were once a distant dream.

The researchers at the 5G Innovation Centre (5GIC) are working on much more than simply improving the speed of our mobile phones, with ambitions of driverless cars and home appliances all controlled via 5G. Partially funded by the UK government, the centre was the first of its kind and has since been joined by the likes of Japan, Taiwan, Russia and South Korea in the 5G race.

Last year, the 5GIC achieved breakthrough connectivity speeds of just one terabit per second and proclaimed it hopes to demonstrate the remarkable technology to the public by 2018. If (like us) you can’t wait that long, we caught up with Professor Tafazolli himself to discuss all things 5G and what exactly we can expect from the Internet of Things.

What is the 5G Innovation Centre?

Tesco Mobile: Can you give us a bit of background about the 5G Innovation Centre – when you started, what the objectives are and what you’re working on in general?

Professor Tafazolli: We started in 2012; there was an invitation for research into infrastructure, not specifically 5G, from the UK government and the higher education funding council of England, who provide funding to higher education in England. When we heard about this funding, I was thinking what we could do with it.

Being involved in mobile communications for 2G, 3G, 4G and the history of the UK in radio communications, I thought that it was timely to have the infrastructure to do research into technologies beyond 4G and 5G. So, we put in a bid and in October 2012, it was successful.

I talked to our industry partners, mainly Vodafone, Telefonica, Fujitsu, Samsung and Sony, who were all supportive. We won the bid and were granted £12m by the UK government; then twice that was committed by our industry partners, so all together about £36m.

What work is the 5GIC doing?

PT: The idea is to work on the step change technology that 5G will use. The advanced research evaluates our technology, mathematical modelling, computer simulation, building the technology, prototyping it and testing it in a wide area. Now, we have raw data and 44 base stations.

TM: So, you have basically a 5G network?

PT: Not really. 5G needs to be standardised first. Lots of people are proposing different technologies. It will go through the standardisation process, then we select the technology and start implementing, testing and optimising it, before eventually bringing it to the market. What we have now is an advanced version of 4G. So, we have the infrastructure in place and gradually over time, we’ll change it to 5G technologies.

Looking at the plans, 2018 is the first quota for when we would like to demonstrate full 5G technology. If we achieve this milestone, we will be the first in the world to show 5G technology in a real environment, not in a lab. Our vision is 5G, that’s not just higher speed, unlike many people think, but a system that provides high capacity with at least 100x more users connected.

TM: When you say 100x more users connected, does that mean in a football arena everybody will be able to connect?

PT: Yes, there is enough capacity for everyone to be connected, even in a high-density environment, like a football stadium. In addition to people, we think that 5G will provide connectivity between devices. Everything will be wireless. It’s not only communication. It will be connecting devices together, homes will become smart homes, cities become smart cities, countries become smart countries and continents become smart continents. So, 5G is not only about speed, it’s about connectivity.

But we want the system to be highly secure because of malware and attacks on the network. When we have every aspect of our life connected, then there is a big risk. So, the system must be reliable, and it must be robust.

5G Relay Base Station

5G Relay Base Station

These are the major step changes that we think 5G should bring from previous generation systems. 1G was pure voice, 2G was digital voice, 3G was 50/50 voice and data, 4G was mainly data and higher speed. Every generation has had higher and higher speed. With 5G, we don’t think it’s justifiable to have higher speed only. It must provide connectivity of people and devices, and it must be highly reliable

TM: To get rid of latency?

PT: Low latency translates to higher speed. But (…) our objective is not just to achieve speed; if it was speed, we already have the technology that can do 1000x faster than the highest 4G speed, so we could say we’ve finished the 5G project.

But, that’s not our objective. Our objectives are the ones I’ve mentioned – reliability, robustness, security, and latency. We want to support 100x or 1000x more devices on the network. The system must be energy efficient because with current technologies, the energy we use would also be 100x or 1000x more.

TM: If we had 5G on our phones right now and they were running on the 5G network, would it drain the battery dramatically?

PT: With the current technology, yes. That’s why it requires different technology, which is what we are trying to do.

The 5G race

TM: You mentioned the term “5G race” earlier and working with the industry – do you see this process as collaborative?

PT: Yes, it has to be. No single country or company can dictate the global standard. That’s why we have a huge amount of industry partners from China, Canada, South Korea, Japan, Europe and the UK, of course. We all work together and collectively agree on what should be standardised.

But, our plan is not just to do research and testing. We have a 5G centre set-up, a standard group chaired by O2/Telefonica and our partners look at our research and provide input. We believe Wi-Fi is part of the whole story as well.

TM: Within the European Union and the UK in general, when do you think we will have access to 5G technologies?

PT: The first version of 5G technology should be in the market by 2020. Then, it will evolve to meet other objectives. 2020 is the target.

TM: How will it be rolled out within the EU and the UK? Is it going to be something that is universally accessible, because 4G often tends to be more accessible in city centres?

PT: Yes. It is different, not only from a technological point of view, but from the global acceptance of 5G. For 5G to work, it has to work with 4G. The reason we only have 4G in city centres is because of its capacity. As I said, 5G is not just capacity but also connectivity of devices with a very high data rate. We mean to cover buildings, factories and the commercial environment, so it will have more capacity as well as connectivity between devices.

The accessibility of 5G

TM: Obviously, the mobile industry is going to change. With the current price of data, we mentioned that it might be a premium service, do you think it could be widely accessible?

PT: It has to be because it’s not just going to be high-speed data. The business model of the operators will have to change because they have to provide connectivity to utility networks like gas, electricity meters and connecting cars. Eventually, we’ll have driverless cars and 5G technology should evolve to meet these needs; we can’t just come up with a new technology for driverless cars. However, it’s a long way away, not before 2025.

We want this technology to provide economies of scale, so the world can develop different technologies and applications on top of that. Devices of differing capabilities will all be connected, so it will have an impact on the internet architecture – the wired part of the network must change. So, if it was only capacity and speed then 4G is good, but if you want to connect our highway roads, it must be something smarter. Homes become smarter, hospitals become smarter. We have an ageing population and they cannot keep going to their GP and hospital. Remotely you can control that.

We think of the early 90s when we think about mobile communication and beginning to do these sorts of things. Mobile communication has changed our culture, our life, the way we do business, our private lives; it’s all dramatically changed. Now, 5G will change this; it will be a catalyst for all this change in the economy and society. Not only just communication but critical parts of our infrastructure, the services that a nation requires.

So, what we are doing in the 5G centre is trying to come up with this enabling technology, this fundamental technology that will give you this flexibility, robustness, latency and network architecture to come up with those solutions. In 2030, 15 years from now, the world will be very different and we need to have the technology ready.

The future of mobile phones

TM: Obviously, smartphones are changing a lot and we’re seeing an increasing number of smart wearables as well. It feels like they’re going to become a central part of the Internet of Things. I know you’re not working directly with applications, but do you already see the future of mobile phones changing?

PT: I think they will become more intelligent and do more than just communication. We’re focusing on a couple of areas generated from having transformed data into useful applications. So, we have to come up with the artificial intelligence and model the data. Data coming from a smartphone and data coming from a sensor detecting light should have the format to be able to connect to one another.

It must be a model that they can integrate because each individual piece of data is useful, but not when it’s coming from different machines. We have tested it, so all our students – Grad students and Masters students – can come and use the applications. What I would like to do, but I’m not sure if we can do it, is encourage students to hack it, break it down.

TM: To test how safe the network is?

PT: Yes. Then, we learn where the gaps are and fix them. But, I’m not sure whether we can do that or not. That would be fantastic. I’m sure some smart people could bring the network down if they wanted to. We’d probably allocate part of the network for this purpose. Break it down and then tell us how you did it.

Mobile Phone Evolution

The Evolution of Mobile Phones

Setting the standard for 5G

TM: You mentioned smart cars, smart houses, smart cities, smart continents and obviously, the first smart companies like Apple and Google; do you think we could see these major actors becoming more involved in city planning, into home design?

PT: What most of these companies are developing is based on some sort of Wi-Fi system, some sort of proprietary solution, which is good, because people are thinking in this direction. It is encouraging that the industry is taking it seriously and not just the computer industry. However, to make this work on a global scale we need a minimum standard, so everybody builds everything on top of that and the networks talk to each other. If we carry on developing these things, these proprietary solutions, it will stay small.

That’s why I am strongly supportive of a common standard and many people don’t like standards; they say “big boys control everything”. The problem is not having a standard; the problem is perhaps the standards should be regulated and opened to everybody. Because when we talk about new connectivity, a new type of digital economy, we need different regulations.

TM: So, 5G will become the new standard?

PT: The whole idea of the concept, the vision of how we should look at good and bad connectivity, will be very different to the way we have done it for the last 30 years with 1G to 4G. We’re no longer just working within that framework of higher speed.

Many people still don’t know what 5G is because everybody says 5G is going to do more of the same thing, high speed, and that’s where the confusion comes in. That’s why I always say 5G is a special generation. It will be the first generation with full connectivity and then after, 5G will be a second generation of connectivity, then a third generation of connectivity, which is why we’ll not have 6G.

What Professor Tafazolli has made clear is the development of 5G heralds much more than faster data speeds for smartphones. It beckons the Internet of Things, which will see everything connected in our homes, our cities and our countries.

5G is set to transform society as we know it, connecting everything from cars to hospitals, creating a safer and more energy efficient world. What’s more, we won’t have to wait too long to see the first iteration of the network, as the 5G Innovation Centre hopes to introduce it to the world by 2020.

5G Innovation Centre officially opens at the University of Surrey

The University of Surrey today opens its state-of-the-art 5G Innovation Centre (5GIC), securing the UK’s role in leading the development of the next generation communications technology, 5G.

The 5G Innovation Centre

Housing over 170 researchers and attracting over £70 million of investment, including £12 million from the Higher Education Funding Council for England (HEFCE), the 5GIC is the world’s largest academic research centre dedicated to next generation mobile and wireless connectivity.

The Centre brings together leading academic expertise and major industry partners to define and develop a global 5G network that will radically change lives across the world. Through their work, they have already developed a technology that enables speeds of one terabit per second (Tbps) – more than 1,000 times faster than the highest 4G speed, and filed over 15 patents.

Professor Rahim Tafazolli, Director of the 5GIC, said: “While we have already achieved record-breaking speeds, 5G is not only about delivering faster mobile internet. It is a transformative set of technologies that will radically change our private and professional lives by enabling innovative applications and services, such as remote healthcare, wireless robots, driverless cars and connected homes and cities, removing boundaries between the real and cyber worlds. These capabilities make 5G a ‘Special Generation’ of connectivity.

“The true impact of 5G will come from the innovative applications the new network will enable, some of which are yet to be realised. The opening of the Centre today marks an important step in allowing those from across the globe to work with us in developing the new network and for partners, other universities and industry to test out their new applications in a real world setting, before they are brought to market.

“The ethos of the Centre is not built on competition but cooperation.  5G will be achieved through global collaboration so that everyone will benefit from working to a single standard. This technology will then be commercialised from 2020, driving economic development and research for the UK, while delivering research that will impact the world.”

Jo Johnson, Minister for Universities and Science, said: “The development of 5G presents a significant economic opportunity and this world-leading centre will position the UK at the forefront of research into the next generation of communications technology. The Government wants Britain to be the best place in Europe to innovate and we are committed to supporting collaborations like this one to ensure pioneering research continues to improve people’s lives.”

Video of the future

Opening alongside the Centre is the 5GIC’s new testbed facility, providing researchers with a fully-functioning advanced 4G network. Over time, it will be upgraded to include fully-fledged 5G technologies and large scale Internet of Things (IoT). By 2018 the testbed will be able to deliver 10Gbs/per cell, ten times faster than the highest speed available over 4G.

To demonstrate the potential of the testbed, 5GIC researchers and partners are today unveiling a pioneering wireless technology performing mobile streaming of ultra-high definition video.

Developed in partnership with Huawei, BBC R&D and the 5GIC, ultra-high-definition (4k) video will be streamed to a mobile device over an enhanced outdoor mobile network, providing a first major step in delivering the expected capacity of 5G.

Professor Rahim Tafazolli explained: “Using evolved hardware and software, the demonstration showed the capabilities 5G could hold for bandwidth hungry applications such as ultra-high definition video on the move. This provides much higher quality, less compressed images than 4G/LTE, streamed to a mobile device or television.”

5G Supporting the Internet of Things (IoT)

Another key demonstration is focussed on the requirement for 5G to provide the necessary “backbone” to connect the billions of devices which will form the future IoT, supporting thousands of devices per square kilometre in addition to smart phone usage. The demonstration shows how a new (5G-Sparse Coding Multiple Access) radio waveform can support at least three times the number of IoT devices than would be possible with 4G. It is a great example of how the newly opened 5GIC testbed can be used to trial real 5G IoT applications, illustrating the level of improvement in network capacity that can be expected from a 5G network.
