R2 Wireless, a security technology company developing passive RF spectrum awareness solutions, has raised more than $5 million in new funding, bringing its total capital raised to over $13 million. The funding will support the company’s expansion in the United States, including additional engineering hires and new defense and commercial partnerships following deployments in Europe and the Middle East.
The company’s Odin spectrum dominance platform passively monitors radio frequency signals to detect, classify, and geolocate transmissions from sources including drones, cellular devices, Wi-Fi, Bluetooth systems, and rogue RF emitters. Unlike conventional RF detection systems designed for stable environments and known protocols, the Odin platform is intended to operate in congested and contested RF environments where anonymized threats are increasingly common.
According to R2 Wireless, the system provides RF visibility without transmitting signals, requiring spectrum permits, or introducing privacy concerns. The platform learns the RF environment in real time to help military, government, and critical infrastructure operators identify potential threats and risks before taking action.
The company recently entered into a formal agreement with a NATO member nation’s Ministry of Defense and also signed a strategic partnership with a major European energy infrastructure provider. R2 Wireless was also named a winner in the U.S. Army’s xTech Disrupt competition in the counter-UAS category.
