Connecting the future: what is 5G?

By Scott Faulds

Over the years, as technology has evolved, the way in which we all use and access the internet has changed dramatically. The devices that can access the internet have shrunk and become portable, from laptops that allow us to work anywhere to smartwatches that we can use to play music from our wrists.

At the same time, as more devices have gained the ability to easily connect to the internet, our usage has changed massively; we now consume a great deal of audio and video online. This has become even more apparent during the Covid-19 pandemic, with many of us turning to video conferencing tools to work from home and keep in contact with our friends and family.

Additionally, in recent years, we have begun to see our homes, cars and cities become ‘smart’ via the power of the internet, enabling a whole new generation of devices that can connect and exchange data.

In response to changes in the way we all use and access the internet, the mobile network infrastructure has evolved to allow for greater bandwidths, lower latency and ultimately faster connection speeds. The next generation of mobile network technology – known as 5G – will facilitate new data-driven technologies, such as, automation, self-driving cars and artificial intelligence.

What is 5G?

5G is the next generation of mobile internet technology, which operates across a broad spectrum of radio waves that will allow for faster, always-on access to the internet. It’s estimated that 5G will enable internet speeds up to 600 times faster than those experienced on 4G networks today. This would allow you, for example, to download an ultra-high-definition movie in 25 seconds. The ability to transfer data at these speeds allows for technologies, such as artificial intelligence and autonomous vehicles, to operate effectively. Some experts claim 5G could lead to a new era of productivity and growth.

However, the physical infrastructure required to build a 5G network can be difficult to deploy. The fast speeds achieved by 5G networks rely upon what is known as millimetre waves, which operate at a higher frequency than our current mobile networks. These waves have a shorter range and can be easily disrupted by obstacles, such as buildings, people and even rainfall. Therefore, to ensure network reliability, a 5G network will have to operate across low, medium and high frequencies. Each of these frequencies will require separate network infrastructure and will have various trade-offs, in terms of speed and service area.

As a result of the distance and obstacle limitations of 5G, there will be a need for a dramatic increase in the amount of physical infrastructure required to ensure reliable service, particularly in built-up urban environments. According to a recent report by McKinsey, a 5G network will require 15 to 20 network access points per square kilometre in densely populated areas, compared with 2 to 5 network access points required for existing mobile networks. Subsequently, the cost involved with establishing this new infrastructure ensures that in the short-term, we are unlikely to see the launch of nationwide 5G coverage anytime soon.  

The power of data

The ability to exchange large amounts of data at speed can have a significant positive effect on our economy. Research from Barclays, indicates that the deployment of 5G has the potential to increase annual UK business revenues by up to £15.7 billion by 2025. Additionally, the ability to exchange data at speed opens up new opportunities for us to improve the efficiency of the operation of our cities.

The advent of the smart city, where everything from streetlights to trains can communicate with each other, can only truly come to fruition when combined with the data speeds facilitated by 5G networks. The main benefit of establishing a fully-fledged smart city is the ability for cities to become sustainably more efficient, through the extrapolation and analysis of data. For a smart city to be at its most efficient, the collection and analysis of this data will have to occur in almost real-time and will rely heavily on artificial intelligence and automation. 

A study conducted by Massachusetts Institute of Technology (MIT) found that in New York City congestion could be reduced by up to 75% through the deployment of a ride-sharing algorithm built using real-time data generated by taxis and incoming requests. The system would allow drivers to work shorter shifts, create less traffic, reduce air pollution and shorten commutes (with an average wait time of 2.7 minutes).

The creation of smart cities, underpinned by 5G, could potentially allow us all to live in cities which are more efficient and responsive to changes in our behaviour. Analysis conducted by Cisco, has revealed that the efficiencies generated by smart city technology could result in cost savings of up to $2.3 trillion globally.

Therefore, it could be said that 5G technology has the potential to allow businesses and governments to make costs savings and generate new forms of revenue.

Final thoughts

The deployment of 5G networks will provide the base for the technology of the future to operate and enable innovation to thrive. It is likely that the speeds and reliability offered by a fully-fledged 5G network could generate economic benefits and allow governments to make cost savings by leveraging big data to make our cities operate in a more efficient manner.

However, the deployment of 5G will be a complex and potentially costly undertaking, and it will be a long time before we see the establishment of nationwide 5G coverage. Therefore, although there is a wide range of benefits associated with the establishment of a 5G network, it should not be seen as a silver bullet that will generate instantaneous economic benefits.

Ironically, the future of high-speed internet, will take time and will require a great deal of investment before the benefits are realised.

In recent years, cities across the UK have begun to explore how they can best capitalize on technological advances to help to create places which operate in a more efficient and sustainable way. The concept of the smart city is relatively wide-ranging; in basic terms, it can be described as an urban area that uses various forms of technology to gather data that can then be analysed to reveal insights about how citizens engage with their environment. The advent of smart city technology, and its ability to be installed in numerous forms across existing city infrastructure, means that it can often be challenging to assess and understand the success of its deployment.

A recent article published in Emerald Open Research – UK smart cities present and future: An analysis of British smart cities through current and emerging technologies and practices – aims to address this issue by providing an overview of the progress of 26 UK cities which are currently deploying smart city technology. The article attempts to analyse the current state of the smart city roll-out and evaluate the types of technology that are being installed. As the concept of the smart city is one that is fluid, each city’s implementation of the technology can vary, as can the success of the integration.

Designing a smart city evaluation framework

In order to understand the current state of the smart city rollout, the article employs a framework that can be used to assess what types of technology have been deployed and the current state of the deployment.

The following categories are used to classify smart city technology:

Essential services – 5G, full-fibre internet, Internet of Things

Smart Transportation – digital ticket booking, smart cards, electric vehicle charging points

Broad Spectrum – retrofitting buildings, digital social inclusion schemes, hackathons

Business Ecosystem – innovation hubs, co-spaces, tech entrepreneurial networks 

Open Data Provider – urban dashboards, urban models, big data

The state of the rollout of smart technology is evaluated on the following scale:

0 – no measures underway

1 – public announcement of plan

2 – study in advanced stages/detailed roadmap

3 – testing/trials

4 – installation of technology on smaller scales

5 – fully established and integrated into the city

By analysing relevant documents/news reports and applying the aforementioned framework, the article finds that the most common type of smart city infrastructure installed in cities across the UK is technology which enables the collection of open data. In particular, a group known as Smart Cities Scotland has been found to have one of the most advanced implementations of open data technology. This is due to the creation of an open source data platform which allows anyone to access the data collected and develop smart city technology that directly responds to the needs of these cities.

Approaches to deploying smart city technology

Through the application of the framework, London and Bristol were discovered to be the cities in the UK with the most advanced implementation of smart city technology; this was largely due to the widespread use of all of the categories. However, the authors also suggest that the steps taken by smaller cities, such as Dundee and Peterborough, are often of more interest, as they clearly show the two prevailing approaches to the implementation of smart city technology.  

The approach taken by Dundee is one in which cities select one or two smart city categories and focus on getting these technologies to become fully integrated and widespread. For example, Dundee has chosen to focus on the integration of open data (via Smart Cities Scotland) and smart transportation technologies, in a bid to create a fully sustainable transport network. An in-depth focus on these areas has enabled Dundee to become a leader in the switch to zero-carbon transport, through the creation of the Mobility Innovation Living Lab and the electrification of 20% of the local taxi fleet. However, whilst the implementation of open data and smart transportation technology places Dundee as a leader in these categories, their implementation of essential services or broad spectrum technology is poor when compared to other cities in the UK.

Peterborough, on the other hand, has taken an almost diametric approach and is focused on deploying a broad variety of smart city technologies, that will allow them to reach their goal of becoming a gigabit city and establishing a circular economy. The city has deployed a variety of online platforms, designed to engage citizens and business alike, to come together and share resources that will allow Peterborough to support and empower everyone in the city to minimize waste.

The future of the Smart City

As well as analysing the current state of the smart city rollout, the article also discusses the future of the smart city and sets out its expectations for the next decade. A key theme discussed is the concept of a more connected city, powered through 5G and increased network capacity, which will allow for city infrastructure to communicate and easily respond to changes in the way citizens are engaging with the urban environment. However, the article concludes that we are unlikely to see any major visual changes to our cities, apart from an increase in electric vehicles and their accompanying infrastructure. A great deal of the smart city technology currently being deployed in UK cities tends to occur behind the scenes, but, these changes will allow councils to harness the power of data to make better decisions about the future day-to-day workings of our cities.

To conclude, this article provides one of the first overviews of the state of the smart city rollout across the UK, allowing for a comparative analysis of the different approaches cities have taken to implement various forms of smart city technology. Establishing a framework of how to evaluate this progress allows those interested in smart city technology to assess which smart city technologies are most prevalent and which cities are at a more advanced stage of the rollout.

In short, this article will be extremely informative for anyone with an interest in learning more about smart city technology and its deployment in the UK.

The 5G arms race: the UK’s strategy to become a global leader in 5G technology

Posted on by

By Steven McGinty

On 8 March, the UK Government published their strategy for developing 5G – the next generation of wireless communication technologies.

Released on the same day as the Spring Budget, the strategy builds on the government’s Digital Strategy and Industrial Strategy, and sets out the government’s ambition to become a global leader in 5G.

Accelerating the deployment of 5G networks, maximising the productivity and efficiency benefits to the UK from 5G, creating new opportunities for UK businesses, and encouraging inward investment, are the strategy’s main objectives.

If the UK makes progress in these areas, the strategy argues, 5G infrastructure has the potential to become an enabler of smart city technologies, such as autonomous vehicles and advanced manufacturing, and to support the expansion of the Internet of Things – the interconnection of people, places, and everyday objects.

5G Innovation Network

Although the strategy highlights the enormous potential of 5G, it makes clear that 5G technologies are still in development, and that the majority of funding will need to come from the private sector.

To support the growth of a commercial market, the strategy explains, a new 5G trials and testbed programme will be introduced – through a national 5G Innovation Network – to coordinate the development of 5G services and applications. This programme will help government and private sector partners understand the economics of deploying 5G networks, ensuring that technologies can he delivered in a cost-effective way, and enabling best practice to be captured and knowledge disseminated.

The government is investing an initial £16m into the programme (involving partners such as UK Research and Innovation and the Government Digital Service), and has targeted a trial of end-to-end 5G (high speed connectivity without the need for intermediary services) by 2018. In February, Ericsson announced that they had a successful end-to-end 5G trial in Sweden, alongside partners SK Telecom Korea.

Improving regulations

To support the development of 5G, the strategy suggests that there may need to be regulatory changes, particularly in the planning system. As such, the government has committed to reviewing current regulations before the end of 2017, and then to conduct regular reviews, as partners learn more from their 5G trials.

Local connectivity plans

The strategy highlights the important role local regions play in the deployment of mobile technologies, and explains that the government will be consulting with councils on how planning policies can be used to provide high quality digital infrastructure.

However, it also suggests that there may be a case for introducing ‘local connectivity plans’, which would outline how local areas intend to meet their digital connectivity needs. Interestingly, the strategy highlights that evidence, such as local plans, may be taken into account when the government is making funding decisions for local infrastructure projects.

Coverage and capacity, infrastructure sharing, and spectrum

The strategy accepts that the move towards 5G won’t be as straightforward as the move from 3G to 4G. Instead, 5G technology will be developed alongside the expansion of the 4G network.

In addition, the government has accepted the recommendations of the National Infrastructure Commission (NIC)’s ‘Connected Future’ report, which states that unnecessary barriers to infrastructure sharing between telecommunications companies must be tackled. The strategy states that it will explore options for providing a clearer and more robust framework for sharing.

Increasing the available radio spectrum was also highlighted as key to developing 5G technology. The strategy notes that the government will work with Ofcom to review the spectrum licensing regime to help facilitate the development of 4G and 5G networks.

5G strategy’s reception

Natalie Trainor, technology projects expert at law firm Pinsent Masons, has welcomed the new 5G strategy, explaining that:

“…technology and major infrastructure projects will become much more interlinked in future and that the plans outlined can help the UK take forward the opportunities this will present.”

In particular, Ms Trainor sees the establishment of the Digital Infrastructure Officials Group – which will bring together senior staff from across departments – as a way of providing greater awareness and co-ordination of major public projects that involve digital infrastructure. Ms Trainor also hopes that the new group will encourage the Department for Transport and the Department for Culture, Media & Sport (DCMS) to work with industry to develop digital connectivity on the UK’s road and rail networks.

Professor Will Stewart, Vice President of the Institution of Engineering and Technology, similarly welcomes the new strategy but highlights that the funding announced will ‘not come anywhere close’ to the investment required to deliver 5G across the UK. In addition, he also makes it clear that coverage and regulatory change will be vital, stating that:

“The biggest challenge for government will be improving coverage for all, as 5G cannot transform what it doesn’t cover. And achieving universal coverage for the UK, outside high-capacity urban areas, will not be affordable or achievable without regulatory change.”

Former Ofcom director and author of The 5G Myth, Professor William Webb, has also applauded the government’s plans, even though he is an outspoken critic of the 5G industry. For Professor Webb, the strategy recognises that we are in the early stages of 5G technology, and that there is still a need to develop 4G networks.

Final thoughts

5G technology provides the UK with the opportunity to become a genuinely smart society. Yet, as the strategy acknowledges, 5G is still in its infancy and the idea of a 5G network across the UK is a long way down the road.

The new 5G strategy includes a number of positive steps, such as listening to the recommendations of the NIC report, and exploring the realities of deploying 5G networks. This cautious approach is unlikely to show any significant progress in the short term, but does provide a focal point for academia, government, and industry to rally around.
