Digital Catapult onboards a further nine companies from across the globe to trial Open RAN in the UK

Posted 8 Dec 2022

Digital Catapult, working in partnership with Ofcom, has given nine companies the opportunity to accelerate the development of their Open RAN products, through becoming part of the next phase of its SONIC (SmartRAN Open Network Interoperability Centre) Labs programme funded by the Department for Digital, Culture, Media and Sport (DCMS).

The companies include both UK and global Open RAN vendors new to the UK market, such as VVDN based in India, SOLiD headquartered in South Korea and ASOCS based in Israel, as well as six other companies with existing engagement in the UK market, namely: Accelleran, CableFree, Effnet, Phluido, Radisys and VMware. 

Digital Catapult will work with the organisations to integrate their Open RAN products into working end to end systems and conduct interoperability and performance testing in an indoor environment. The nine companies are the second group of organisations to gain access to SONIC Labs, with the first group of companies announced earlier this year. 

The SONIC (SmartRAN Open Network Interoperability Centre) Labs programme aims to allow new solution providers to enter the telecoms supply chain in the UK. It will drive forward the rollout of a new wireless communication technology known as Open Radio Access Networks (Open RAN), which enables mobile networks to be built using a variety of different equipment suppliers. 

This phase of the programme will focus on system integration, exploring Ran Intelligence Controller (RIC) maturity, and investigating ARM-based Open RAN Implementations. Three organisations (ASOCS, Accelleran and Radisys) will play the role of a System Integrator and will be responsible for End to End Interoperability, benchmarking and swapability experimentation. The System Integrators will lead the installation of software and firmware, as well as capturing optimisations and performance improvement measures.  

All nine Open RAN vendors will share best practices around the implementation of Open RAN standards, solve specific Open RAN integration problems, collaborate with new partners to create knowledge, and even have the chance to showcase their products to potential customers and end-users. 

Accelerating the adoption of Open RAN technology has the potential to diversify the UK 5G supply chain so it is fit for the future – making it more secure and accessible for new market entrants.

Alongside access to Digital Catapult’s advanced facilities and technical support, participants will also have the opportunity to take part in thought-leadership events throughout and beyond the six-month technical programme and will benefit from networking opportunities and targeted innovation activities to accelerate their route to commercialisation.

Notes to Editors 

More about the SONIC Labs project:

The participating companies in this phase of the project will be given access to the SONIC Labs facility to test their products and solutions including software and firmware installations and configurations of the Open RAN components. The Open RAN vendors will also work with the Digital Catapult 5G technology team to conduct integration, interoperability and end to end (E2E) performance benchmarking experiments. The experimental process aims to capture key results and learnings, along with trialling optimisation and performance improvement measures. SONIC Labs will share the lessons learned from this integration testing in the coming months. 

Participating companies include:


Headquartered in Antwerp, Belgium, Accelleran is an Open RAN pioneer, with software solutions enabling a diverse multi-vendor RAN ecosystem that creates greater flexibility, efficiency and reduced costs for operators and private networks. Accelleran brings the dRAX™ platform, which includes the Cloud Native CU, RAN intelligent Controller (RIC) developer platform and systems integration capabilities to the SONIC labs programme.


Based in Israel, ASOCS is empowering industrial enterprises to connect their production lines to edge applications by providing them with a cloud-based private 5G network and a scalable SaaS model. ASOCs brings a Distributed Unit (DU) and Centralised Unit (CU) to the SONIC Labs testbed. 


A latest-generation Open RAN Radio Unit for SONIC Labs Cohort 2 will be provided by CableFree: Wireless Excellence, a UK-based equipment vendor with a deployed base of customers in more than 80 countries. Based on the Oxford Science Park, the company designs and manufactures high-performance wireless solutions including 5G Macro and Small Cell Radios.


Effnet AB, based in Sweden, its 5G RAN software is a disaggregated solution with open RAN interfaces. Effnet is bringing its 5G DU software running on both Intel and Arm platforms, integrated with 5G PHY/UL1 from 3rd party vendors to SONIC Labs for testing and integration with RAN software components from other vendors.


Phluido is a pioneer company in the fields of fronthaul technology and cellular network virtualisation from San Diego, California. The company will be in charge of providing the physical layer a Distributed Unit (DU) to the SONIC Labs programme, for deployment on Arm machines.


Radisys, a global leader in open telecom solutions, enables service providers to drive disruption with new open architecture business models. Leveraging O-RAN standards for open interfaces and RAN disaggregation, multi-vendor Open RAN deployment is realised in SONIC labs with Radisys 3GPP Rel 16 compliant CU and DU software on COTS hardware with radio and core network from other vendors. 


SOLiD distributed antenna system (DAS) technology and O-RAN solutions enable indoor and outdoor cellular service at many of the world’s best-known and most challenging venues — from the busiest airports and subways to Fortune 500 corporate buildings, hospitals, hotels, universities, sports venues, government, industrial, and logistics facilities. SOLiD continuously innovates to deliver best-in-class modular solutions that scale to every need.
