Technologies & trends

The region boasts expertise and capabilities in a number of key telecom fields.  Learn more about the relevant technologies.


The potential benefits of 5G, future wireless generations and full-fibre digital connectivity can only be realised if we have confidence in the resilience of our infrastructure.

Security features prominently in business and academia across the South West, home to both GCHQ's National Cyber Security Centre and the Cyber Security Operations Centre in Corsham. The South West Cyber Security Cluster is a volunteer-led and government-supported initiative dedicated to improving cyber security skills development, SME business protection and innovation across Cornwall, Devon, Somerset and Dorset.  The region is also home to the UK’s first pan-defence and security cluster. The South West Regional Defence and Security Cluster is a collaboration led by industry and academia with the support of the Ministry of Defence and its innovation directorate, and the Defence and Security Accelerator (DASA). 

The region also boasts strong academic capabilities in the security space. The University of Bristol Cyber Security Group is part of the Academic Centre of Excellence in Cyber Security Research at Bristol. The group conducts cutting edge research focused on: security of cyber-physical infrastructures, software security and the role of human behaviours in cyber security. While the University of Plymouth’s Centre for Cyber Security, Communications and Network Research is an established inter-disciplinary group conducting research in digital forensics, maritime cyber threats, human aspects of cyber security and networking and communications.

Non-Terrestrial Networking

Non-terrestrial networking (NTN) refers to any network that involves space or airborne elements, including satellite communication networks, high-altitude platform systems (HAPS), and air-to-ground networks.

Cornwall Space Cluster is a vibrant centre for non-terrestrial networking, with a dedicated horizontal launch site, the world’s most capable satellite ground station, deep space communications, EO and flight testing. The Satellite Applications Catapult has its Ground Station at Goonhilly, the home of satellite communications. The facility provides users with a ‘bring-your-own solution’ where third party equipment can be installed, offering a high level of connectivity, and data can be transmitted to the Catapult’s facilities in Harwell.

The Bristol-based O-RANOS project is implementing novel backhauling and neutral hosting services with a particular focus on satellite backhaul (mainly GEO and LEO constellations) for connecting to different core vendors.

Artificial Intelligence

Artificial Intelligence (AI) is disrupting industry on a broad scale and the telecoms sector is no exception, with Valuates projecting that the global AI in telecoms market size will reach $14.99B by 2027, up from $11.89B in 2020.

The Bristol Digital Futures Institute draws together expertise from within and outside the University of Bristol, working to fundamentally transform digital innovation, and create more inclusive, sustainable and prosperous futures for all. Their three-year Explainable AI project is exploring how to open up the operation of machine learning and automated decision making for businesses that use these methods and the public that are affected by them. 

Bristol-based O-RANOS project is leveraging the rApps and xApps development framework in the O-RAN Alliance specifications to develop x and r application templates that will enable APIs to interact with Machine Learning production models. While the REASON project is developing advanced solutions for network-edge and network-wide automation that leverage state-of-the art AI techniques.  And the Towards AI Powered and Secure Carrier-Grade Open RAN Platform project, part-based in Bath, is using AI / ML-based analytics to lower the cost of operations for OpenRAN network functions.
