Future RAN: Diversifying the 5G Supply Chain to unlock the full potential of 
Open RAN 

The Department of Digital, Culture, Media and Sport chooses to fund CoMP-O-RAN 

Dense Air Limited, along with a consortium of industry and academic partners, 
has been successful in securing funding from the 'Future RAN competition - 
Diversifying the 5G Supply Chain' run by the Department of Digital, Culture, 
Media and Sport (DCMS).

The project, named 'Coordinated Multipoint Open Radio Access Network', or 
'CoMP-O-RAN' for short, will revolutionise the performance and cost of 
densified 5G NR outdoor small cell networks aimed at delivering pervasive 5G 
coverage across the UK. 5G deployment and mass delivery of gigabit services by 
mobile network operators is critical to the economic development of the UK. 
CoMP-O-RAN provides a densification solution that can enable both public and 
private network operators to extend 5G coverage and capacity to areas that are 
un or under-served because of poor economics using either fully licensed or 
shared access spectrum.

Julia Lopez, Digital Infrastructure Minister 
"Our mobile networks play an increasingly crucial part in our lives and 
businesses, which is why we're investing £36 million in cutting-edge projects 
to ensure our networks are safe and secure for decades to come. I'm pleased to 
see such an outstanding range of innovators are now on board with FRANC as we 
push ahead to build a more competitive and resilient telecoms supply chain."

Successful projects from the DCMS competition for the future of Open-RAN were 
announced on Wednesday 8th December 2021 and receive allocations from the £36 
million of 5G R&D funding supporting the advancement of UK based 5G technology 
developments. The competition directly supports the UK Government's 5G Supply 
Chain Diversification Strategy.

Paul Senior, CEO Dense Air
"On behalf of Dense Air and our consortium partners, we are delighted that the 
UK Government, through its DCMS 5G Future RAN competition, has chosen our 
CoMP-O-RAN project. The technology this project will develop will fundamentally 
change the deployment economics and "cost per Gbit" of Open RAN solutions in 
the UK and other international markets."

In partnership with Airspan Communications Limited, Blu Wireless UK Limited, 
Radisys UK Limited and the University of Glasgow, a consortium led by Dense Air 
Limited will develop an economically deployable 5G NR O-RAN Distributed 
Multiple Input Multiple Output (MIMO) – CoMP-O-RAN. For the first time this 
technology will give both private and public Mobile Network Operators (MNOs) 
the ability to leverage the eco-system of 5G vendors in a cost effective way 
that makes 5G Supply Chain Diversification a reality.

Eric Stonestrom, President and CEO of Airspan Communications Limited
"We are excited to be a member of this consortium. We look forward to working 
with this prestigious group of leaders including DCMS officials, to accelerate 
5G and Open RAN innovation, as Airspan develops new features in our radios 
through split 6 virtualization and embedded mmWave fronthaul transport 
solutions. We believe this technology will play a key role in future 5G 
solutions."

Alan Jones, CEO Blu Wireless 
"As 5G networks begin to scale and densify, innovative ways of maintaining 
performance and bandwidth will be needed.  Using Blu Wireless' low latency 
mmWave technology to enable CoMP-O-RAN will have a significant impact on the 
future economics of 5G NR deployment models across both public and private 
networks."

CoMP-O-RAN will enable future 5G small cell networks to benefit from radio 
processing techniques that are already utilised in Massive MIMO macro-cells. 
Importantly, CoMP-O-RAN will improve the operation of small cells in 
interference limited scenarios such as spectrum sharing in licensed and lightly 
licensed allocations in UK Shared Access spectrum at 3.8-4.2 GHz and US CBRS in 
the 3.55-3.7 GHz band. 

Professor Muhammad Imran of the University of Glasgow's James Watt School of 
Engineering
"This project is a great opportunity for algorithms and techniques developed by 
our Sensing and Imaging group to be implemented in a very promising real-world 
system. We expect that end users will benefit from improved experience and 
reduced costs of digital connectivity. We're looking forward to working with 
our partners to develop the CoMP algorithm"

With the support from DCMS the consortium will focus on improving the economics 
for 5G network densification, enabling better use of vertical roadside and 
indoor infrastructure to deliver lower cost, faster speeds, improved capacity 
and a better service experience for end users in urban centers, suburban 
neighborhoods and even rural locations. However, it is not just about increased 
capacities and faster speeds - CoMP will enhance service reliability and 
availability which is critical in many private networking use cases such as 
Industry 4.0, Healthcare, Critical Communications and future connected and 
autonomous transportation corridors. Real-world test and validation will be 
undertaken primarily at UTAC's Millbrook Proving Ground, home of the successful 
DCMS 5G AutoAir Testbed project.

Peter Stoker Chief Engineer - Connected Autonomous Vehicles, UTAC, Millbrook 
Proving Ground, Bedfordshire
"We are delighted to be supporting the CoMP-O-RAN Consortium. The facilities 
here at UTAC are uniquely suitable for this type of testing as our proving 
ground in the UK is already being used for validating connectivity technologies 
and infrastructure."

CoMP-O-RAN provides a network hierarchy where software and hardware components 
are distributed through the network, driving further innovation from specialist 
vendors which will generate additional employment across both software and 
hardware industries. This will subsequently lead to additional manufacturing 
and supply chain developments in the UK and elsewhere. Where possible the 
consortium will look to source components in areas of regional inequality, 
building on the UK Governments 'Levelling Up' agenda and industry 4.0 strategy 
to promote digital skills. 

Arun Bhikshesvaran CEO, Radisys UK Limited 
"We're excited to be part of this consortium focused on delivering a CoMP-O-RAN 
solution that integrates our award-winning, standards-based ConnectRAN 
portfolio of software for disaggregated O-RAN architecture. We are committed to 
working with our ecosystem partners to create advanced solutions in the 
commercialisation of 5G O-RAN and bring high performance products to the UK 
market."
