Key Takeaways
- Researchers have developed a system using reconfigurable intelligent surfaces (RIS) to control and redirect wireless signals.
- This technology can improve 6G connectivity while reducing interference, potentially enhancing smart home and IoT systems.
- The approach could reduce the energy and computing demands on networks by handling interference before it reaches base stations.
Researchers at the University of Glasgow have made significant strides in addressing one of the major challenges facing 6G technology: electromagnetic interference (EMI). By developing a system using reconfigurable intelligent surfaces (RIS), they aim to improve connectivity and reduce interference, which has been a persistent obstacle for the development of 6G networks.
The RIS system works by reflecting and focusing wireless signals, redirecting interference, and improving signal strength. Each element on the surface can be programmed individually, allowing researchers to control how signals are directed and managed in real-time.
According to Jalil Kazim from the James Watt School of Engineering, who co-authored the research paper, previous methods for reducing EMI required significant digital signal processing at base stations, consuming substantial amounts of energy. The new approach places an intelligent surface in the environment, shaping the signal path so that interference is handled before it reaches the base station.
This innovation not only promises to enhance connectivity but also has implications for security and privacy. Professor Muhammad Ali Imran, head of the James Watt School of Engineering, highlighted that EMI could pose security risks by potentially allowing unauthorized access to data. The RIS system can direct signals towards trusted users while denying them to unauthorised ones.
The technology's potential benefits extend beyond connectivity improvements. It could significantly reduce both computing workload and energy demands on the network, making 6G more efficient and sustainable. Additionally, it aligns with the need for secure, flexible networks that will define future communications and sensing technologies.
While commercial 6G networks are expected to begin rolling out in 2030, this breakthrough could pave the way for smoother deployment by overcoming one of its key challenges. The system's ability to handle interference before it reaches base stations could make 6G networks more resilient and reliable.
The development of RIS technology represents a critical step forward in the evolution of wireless communication systems. As 6G is poised to deliver speeds up to 100 times faster than 5G, ensuring smooth operation without significant interference will be crucial for its widespread adoption.
By placing an intelligent surface in the environment, we can shape the signal path in a way that helps handle the interference before it ever reaches the base station.

Our surface can direct the signal towards the users we trust and deny it to the ones we don’t, bringing us closer to the secure, flexible networks which will define the communications and sensing technologies of tomorrow.
