Photon-IV has completed the O-RAN ALLIANCE Global PlugFest Spring 2026, joining 31 companies across 9 labs over a four-month program, and standing as the only Canadian company in the entire event. Photon-IV tested at Virginia Tech, targeting one of the toughest challenges in modern wireless: keeping a connection alive as a device hands off between terrestrial cell towers and satellites.
About the O-RAN Global PlugFest
The O-RAN ALLIANCE Global PlugFest is among the largest industry tests of next-generation open telecom networks. Over four months, vendors validate that their O-RAN-compliant technology interoperates with equipment from other companies across a network of independent labs, a rigorous, standards-based proving ground for open, multi-vendor RAN.
Solving the Terrestrial-to-Satellite Handover
The hardest moments in hybrid connectivity happen at the seam between networks, when a device switches from a cell tower to a satellite and back. Today those transitions routinely drop calls and data. Photon-IV’s AI predicts the handover before it happens, so the link holds through the switch. For defence networks, drones, and Arctic communications, where losing signal is not an option, that difference is decisive.
Independent, Standards-Grade Validation
Completing the PlugFest is more than recognition. It is independent, standards-grade proof that the technology performs against open specifications alongside other vendors’ equipment. Only a small global group of companies can make that claim, and Photon-IV is now among them. “The standard is open. The testing has to be too,” said founder Sanal Kamal.
Built in Waterloo, Tested with the World
Photon-IV develops Stellarlink for defence networks, Predict for IoT, and Swarmnet for autonomous drone systems, built for real customers solving real problems. The company holds an active Department of National Defence IDEaS contract and has filed multiple U.S. provisional patents. Engineered in Waterloo and validated on a global stage, Photon-IV is building the connectivity mission-critical systems depend on.
