ConclusionWith thanks Digital Catapult is a deep tech innovation organisation driving business value byaccelerating the practical application of advanced technologies. Partnering with government, industry and academia, we focus on significantchallenges and opportunities facing the UK’s economy and society, wheretechnology can play a major role in providing solutions. We break down barriers,de-risk innovation, open up markets and responsibly shape the products, servicesand experiences of the future. Digital Catapult is part of the Innovate UK Catapult Network. Catapults provide aunique combination of cutting-edge R&D facilities and world-class technicalexpertise to support UK business innovation. Visit www.digicatapult.org.uk for more information. SONIC (SmartRAN Open Network Interoperability Centre) Labs is acommercially-neutral, collaborative, environment for testing interoperabilityand integration of open, disaggregated and software-centric network solutionsand multi-vendor architectures. Part of the UK’s national 5G Supply ChainDiversification Strategy, SONIC Labs is funded by the UK Government’sDepartment for Science, Innovation and Technology (DSIT), and co-deliveredby Digital Catapult and Ofcom. It has been designed to offer network vendors, operators and integrationcompanies: ■A place for collaborative, peer-assisted, integration and interoperabilitytesting of products and solutions at a pre-commercial development stage,addressing the challenges of multi-vendor end-to-end solutions.■A technical platform. A commercially-neutral, multi-tenancy open networktestbed providing real-world indoor and outdoor scale environments,including test and measurement capabilities.■A programme focused on helping vendors accelerate technologydevelopment and early-stage integration work, with targeted innovationand acceleration activities. About theWireless InfrastructureIndustry Group The Wireless Infrastructure Industry Group is part of the SONIC Labs strategicgovernance model. The objective of this group is to explore the requirements ofreal-world Open RAN deployments through working with partners including but notlimited to; wireless infrastructure providers, neutral host providers, and managedservice providers (for example Mobile Network Operators, Communication ServiceProviders) to: ■Encourage growth and investment in the UK telecom sector■Identify pathways for vendors’ products■Encouraging the development, integration, management, and operation of openand disaggregated multi-vendor networks, in both the hardware and softwaredomains, such as Open RAN■Facilitate widespread interoperability testing and collaboration■Share insight and gather input on challenges and requirements for Open RAN tobe deployed and how these challenges can be overcome This group represents the network deployment ecosystem in the UK and is apotential adopter of Open RAN technologies for neutral hosts in building andprivate network deployments. Digital connectivity is revolutionising people’s quality of life and iscontinuously changing to adapt to market needs. Along with 5G and 6Gnetworks, Open Radio Access Networks (Open RAN) is one of the hot topicsin the telecoms industry today. This report has been designed and created with the support of the SONIC LabsWireless Infrastructure Industry Group, and through market insights andresearch, to provide an overview of the potential barriers to Open RAN adoptionand proposals as to how to overcome them. To drive forward a more diverse, secure and resilient 5G supply chain andrealise the potential of Open RAN technology, close collaboration is requiredacross the telecoms industry and the UK Government to gain a betterunderstanding of future networks. SONIC Labs is looking to help accelerate technology research and developmentof Open RAN through ecosystem engagement, vendor support (both technicaland business development), integration work, interoperability testing, publicity,sharing lessons learned and successful activities, targeted innovation, andacceleration programmes to bring in new innovators, delivering on the 5G SupplyChain Diversification Strategy, to create a more open, competitive and diversetelecommunication supply market in the UK. What is Open RANand why does it matter? Open RAN is the disaggregation of the radio access network (RAN), enablingnetworks to be built using parts from different vendors.
