Abstract
A method, communication device, and computer program product mitigates Specific Absorption Rating (SAR) exposure to a user who is proximate to a communication device. The method includes an on-device measurement receiver of the communication device detecting a first signal corresponding to transmit signals that are reflected by a first antenna. The method includes a controller determining, based on the first signal a first set of values for a power efficiency parameter. The method includes the controller determining whether both the first value and the second value differ from respective baseline values by respective Specific Absorption Rate (SAR) threshold amounts. In response to the controller determining that both the first and second values differ by the respective SAR threshold amounts, the controller adjusts the power delivered to the first antenna.
