摘要: An electronic device such as a portable may have an antenna and associated wireless communications circuitry. A sensor proximity be used to detect when the is in close user's head. Control circuitry within adjust radio-frequency signal transmit power levels. When it determined that given distance from head, level reduced. not proximity-based limits on removed. Data gathered touch sensor, accelerometer, ambient light other sources for use determining how level.
