Radio Can See Through Walls And Measure Your Heartbeat. Here’s How.

The Call of Duty heartbeat sensor is real. Radio waves were built to carry information. Now AI is learning to read the physical world hidden inside their reflections. I trace the lineage of RF sensing from to the Army-funded Sense Through the Wall program and Biometrics at a Distance -- plus research that pulls breathing, heartbeat, pose and identity out of thin air. The same physics now drives $30 radar chips and telco patents for scanning environments with the cellular network itself: 5G/6G ISAC aka. integrated sensing and communication. The goal is mobile infrastructure that senses drones, robots, traffic and weather -- a real-time map of the physical world. No cameras required.
