What happened and what to do
In a post published on July 10, 2026, Jeff Geerling describes QuadRF, a phased-array radio built with a Raspberry Pi 5 and an FPGA board. Using signal processing and beamforming, the system tracks drones and detects Wi-Fi signals through walls. The demonstration highlights implications for wireless network security and privacy.
A company can respond by assessing exposure across its facilities and networks, then implementing radio-frequency monitoring, access point inventories, and alerts for unauthorized signals or devices. Security procedures and monitoring dashboards can guide response without requiring an AI application.
