Amazon Seeks 'Radar Sensors' Waiver for Touchless Control

Amazon wants waiver of FCC rules limiting power levels of unlicensed devices in 57-71 GHz to let it market “radar sensors” to enable touchless control of “device features and functions” for monitoring sleep hygiene, said an undocketed request posted Wednesday. The agency has granted similar waivers for other gesture-based tech such as Google’s Project Soli, the request said. “Operation at the requested power levels would not increase the potential for harmful interference.”
