Abstract:
Various embodiments of the present invention recognize at least two zones of operation for a communication device. In a first zone, which is sufficiently spaced away from a human head or body that SAR limits will be met, transmit power delivered to an antenna of a communication device may be maximized within any other constraints under which the communication device operates. In a second zone, which is not sufficiently spaced away from a human head or body, transmit power is redistributed such that SAR limitations are met without affecting the transmit power control loop of the communication device. For example, a second antenna physically disposed at a different location within the communication device may be used either instead of, or in addition to, the first transmit antenna in order that the SAR limits are met.
