Company profile
researched Aug 2026Eridan develops radio hardware for wireless networks, describing its product as the first all-digital radio based on polar modulation. Its core technology is a fully digital radio unit built around a proprietary approach the company markets as Ultra-Clean Signal, aimed at improving spectral efficiency and extending usable coverage to the cell edge rather than increasing transmit power.
The company positions the radio for private 5G deployments and other high-demand applications, including AI-driven factory environments, autonomous devices, augmented reality, and rural broadband extension. Eridan states the radio consumes up to five times less power than legacy systems, which it frames as reducing operating expense and simplifying network deployment and operation.
Business model
Eridan supplies radio unit hardware and radio technology for private 5G and broader wireless network deployments, positioning its products around lower total cost of ownership for network operators and enterprises.
Traction
Eridan reports field testing in which its radio sustained over 100 Mbps at a distance of 1.7 km while transmitting at 0.3 W, and announced a completed integration of a full 5G Open RAN solution with OCUDU's open-source CU/DU software.
Latest developments
The company published a press release on the successful integration of OCUDU's open-source CU/DU software with its Ultra-Clean Signal radio technology, yielding a U.S.-developed 5G Open RAN architecture.
