Abstract
A user device may include a transmission power manager to control a transmission power level of a wireless transceiver based on a location of a human body proximate the user device as detected by a proximity sensor. During initiation, the user device may record proximity data. The transmission power manager may perform a statistical analysis of the proximity data to generate refined proximity data that excludes or minimizes outlier data. The modified proximity data may then be compared to preexisting proximity data to determine whether a human body is within a threshold distance from the proximity sensor. When the modified proximity data is outside a threshold from the preexisting stored proximity data, then the modified proximity data may be compared to default proximity data to determine whether a human body is within a threshold distance from the proximity sensor.
