Glasgow Caledonian leads with Secure 60 GHz mmWave Innovation

Glasgow Caledonian University (GCU) have developed a cutting-edge millimetre-wave (mmWave) testbed operating in the unlicensed 60 GHz band, enabling real-time, high-speed wireless communication with enhanced security features. This innovative system integrates a beam-steerable metasurface antenna and low-frequency software-defined radios to dynamically direct communication signals toward intended users while avoiding potential eavesdroppers. The system’s capability to create single or multiple directed beams positions it as a powerful and intelligent platform for short-range, high-frequency applications, including smart factories and indoor healthcare settings.

GCU in partnership with the University of Glasgow, have successfully demonstrated secure high-definition video transmission at 60 GHz with low latency. The testbed lays the groundwork for integrated sensing and communication (ISAC), a critical enabler for next-generation 6G networks. Beyond communication, the system has proven its ability to perform precise environmental sensing, such as monitoring heart rate and breathing patterns using the directional characteristics of the metasurface antenna. This dual functionality is especially relevant for settings that require both secure connectivity and situational awareness, such as contactless patient monitoring and industrial automation.

As GCU advance this technology, their focus shifts towards developing a comprehensive 60 GHz ISAC framework that merges ultra-fast connectivity with intelligent sensing for transformative impact in human-centric applications.
