Abstract:
An apparatus for satisfying Specific Absorption Rate (SAR) compliance criteria comprising a processor configured to receive a first capacitance measurement from a first capacitance sensor, receive a second capacitance measurement from a second capacitance sensor, determine a relative proximity of a human body to a wireless device based on the first capacitance measurement and the second capacitance measurement, and adjust a radio frequency (RF) transceiver's output power from a first output power limit to a second output power limit based on the determined relative proximity.
