Stockholm, Sweden – August 21, 2025
TERASi today 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 string of successes in 2025, with TERASi’s wafer-scale Aircore™ packaging technology powering the world’s largest 6G antenna, ultra-compact filters, and more — further solidifying the company’s position as a leader in next-generation communication technologies.
Operational teams in hostile or remote environments often struggle with traditional communications infrastructure. High-demand scenarios such as military operations or re-establishing communications for emergency responders are hampered by slow, cumbersome deployments, high costs, vulnerability to interception and jamming, and inadequate bandwidth.
The RU1 overcomes these limitations by using ultra-compact, mm-wave radios operating above 60 GHz. The hardware employs highly focused, laser-like beams on a different part of the electromagnetic spectrum, making interception or jamming virtually impossible. TERASi’s patented Aircore™ technology allows the radio to be up to 40 times smaller and up to 100 times lighter than the nearest-in-class products. Deployable in minutes on tripods or drones, the RU1 creates sovereign, gigabit-speed wireless backbones that are up to 50 times faster than satellites, secure and adaptable to rapidly changing environments.
“With the RU1, we’ve created the GoPro of backhaul radios. We’ve taken what used to be a bulky, immobile piece of infrastructure and shrunk it down into something you can hold in the palm of your hand,” said James Campion, CEO and Co-founder of TERASi. “ The need for sovereign, independent connectivity has never been greater. Our mission is to give defence forces, disaster response teams, and critical industries the ability to create secure, high-capacity networks instantly, anywhere in the world, without relying on satellites or fixed infrastructure.”
Designed and manufactured entirely in Stockholm, the RU1’s small size and low power consumption enable off-grid, battery-operated use, eliminating the need to dig trenches or lay power lines. TERASi is already in ongoing negotiations with pilot customers in several major industries. The RU1 can even be deployed on drones, allowing mobile, flexible networks to cover difficult terrain or disaster zones rapidly, with focused signals that reduce the risk of detection.
RU1 is now available for evaluation. To make it field-ready at scale, TERASi is partnering with tactical communications providers, drone companies, and leading system integrators to deliver complete, networking packages that slot directly into existing military frameworks.
