    Abstract: The Equivalent Isotropic Radiated Power EIRP emitted from an array of antenna elements at an access point (1) of a wireless communication network is controlled. The access point (1) is configured to form one or more beams (3, 5) by applying a weightset for a beamforming weighting matrix (12) to one or more signal streams in a first mode of operation. The EIRP is controlled by calibrating transmission phase and gain of a respective transmit chain (13a - 13n) for each antenna element (14a - 14n), providing a polar radiation model for an antenna element of the array, and determining a weightset for the weighting matrix (12) subject to a constraint that a maximum total EIRP for the one or more beams in combination in any azimuth direction is maintained within a predetermined EIRP limit. The determination is based at least on a spatial separation of the antenna elements, the polar radiation model and the calibrated transmission phase and gain of each respective transmit chain.

    Abstract: Specific Absorption Rate (SAR) mitigation techniques are described herein. In one or more embodiments, a host device is configured to implement a SAR mitigation algorithm to maintain compliance with regulatory requirements. The SAR mitigation algorithm may be configured to control radio frequency transmissions (e.g., output levels) for one or more antennas of the host device based at least in part upon an arrangement of an accessory device relative to the host device. By so doing, the SAR mitigation algorithm accounts for adverse influences that accessory devices may have upon radio frequency (RF) emissions from the antennas in some arrangements. The SAR mitigation algorithm may be further configured to account for user presence indications along with accessory device arrangements and adapt transmission power levels accordingly.
