Future Telecoms and National Security

Modern and future telecommunications technologies such as 5G and the forthcoming 6G networks are critical for enhancing communication, driving economic growth and enabling innovation across numerous sectors. These next-generation telecom systems will support smart cities, power plants, autonomous vehicles and emergency communication services. However, the rapid advancement and integration of telecoms technology bring considerable national security challenges. Vulnerabilities in telecom infrastructure, recently highlighted by breaches attributed to state-linked actors like China's Salt Typhoon group, underscore the strategic importance of securing these networks.

The UK is actively addressing risks through diversification of telecom supply chains, promoting Open Radio Access Networks (Open RAN), and investing in R&D focused on resilience, security and energy efficiency. Furthermore, emerging capabilities in sensing technologies and AI integrated within telecoms infrastructure promise significant advancements but also introduce new layers of complexity and risk.
