TERASi, a Swedish developer of secure communications systems for mission-critical operations in defence, disaster relief, and industrial operations, led by James Campion, Adrian Gomez, and Bernhard Beuerle, has unveiled the RU1, the world’s smallest ultra-compact radio with military-grade security, designed for rapid deployment and secure communications.
This announcement follows a strong 2025 for TERASi, with its wafer-scale Aircore™ technology powering the world’s largest 6G antenna, compact filters, and more—cementing its leadership in next-gen communication tech. In hostile or remote environments, traditional communications often fall short—military and emergency teams face slow deployment, high costs, jamming risks, and limited bandwidth in critical situations.
The RU1 solves these challenges with ultra-compact mm-wave radios above 60 GHz, using laser-like beams that are nearly impossible to intercept or jam. Powered by TERASi’s Aircore™ technology, it’s up to 40× smaller and 100× lighter than alternatives. Easily deployed on tripods or drones, RU1 enables sovereign, gigabit-speed wireless backbones—up to 50× faster than satellites and built for dynamic environments.
Built in Stockholm, the RU1’s compact form and low power draw support off-grid, battery-powered use—no trenches, no cables. It can be drone-mounted for rapid, mobile coverage across tough terrain or disaster zones, with focused beams that minimize detection. TERASi is already in talks with pilot customers across key industries.
The RU1 is now available for evaluation. To scale field deployment, TERASi is working with tactical comms providers, drone firms, and top system integrators to deliver turnkey networking solutions compatible with existing military systems.
