Abstract:
A method, communication device, and computer program product mitigate Specific Absorption Rating (SAR) exposure to a user proximate to a communication device. The method includes an on-device measurement receiver of a communication device detecting a first signal level corresponding to power delivered to a first antenna. The method includes a controller determining a first return loss value based on a first transmit power setting and the first signal level. The method includes the controller determining whether the first return loss value differs from a baseline value by a threshold amount. In response to the controller determining that the first return loss value differs by the threshold amount, the controller causes the communication device to reduce the power delivered to the first antenna.
