Abstract

A system and method for detecting proximity of a user within a particular distance of a radio device is disclosed. The method includes transmitting a signal via a transmitter and antenna of the radio device, receiving a received signal via a receiver and the antenna, processing the received signal for distinguishing a signal reflected from the user from a leaked portion of the transmitted signal, and reducing power of the radio device in response to the processing.
