A method implemented by a computing device to control one or more antennas of the computing device configured to provide wireless communication functionality comprising: instantiating by the computing device a Specific Absorption Rate,SAR, mitigation algorithm that is dependent upon user presence indications and arrangement of an accessory device connectable to the computing device relative to the computing device; ascertaining indications of user presence with respect to the one or more antennas; detecting an arrangement of an accessory device relative to a computing device to which the accessory device is physically connectable; obtaining accessory identification data indicative of an identity of the accessory device; and applying the SAR mitigation algorithm to control radio frequency transmissions for the one or more antennas of the computing device according to the ascertained user presence indications and the detected arrangement of the accessory device, including referencing a mapping data structure defined to associate antenna operational parameters with accessory arrangements for each different accessory based on accessory identification data, to determine antenna operational parameters associated with the obtained accessory identification data and the detected arrangement of the accessory device, wherein applying the SAR mitigation algorithm comprises reducing a transmission power level of at least one of said antennas to maintain compliance with a legal limit established for SAR in case of user presence indications and enforcing a maximum transmission power level for each of the one or more antennas established with respect to the detected arrangement of the accessory device in case of no user presence indications. instantiating by the computing device a Specific Absorption Rate,SAR, mitigation algorithm that is dependent upon user presence indications and arrangement of an accessory device connectable to the computing device relative to the computing device; ascertaining indications of user presence with respect to the one or more antennas; detecting an arrangement of an accessory device relative to a computing device to which the accessory device is physically connectable; obtaining accessory identification data indicative of an identity of the accessory device; and applying the SAR mitigation algorithm to control radio frequency transmissions for the one or more antennas of the computing device according to the ascertained user presence indications and the detected arrangement of the accessory device, including referencing a mapping data structure defined to associate antenna operational parameters with accessory arrangements for each different accessory based on accessory identification data, to determine antenna operational parameters associated with the obtained accessory identification data and the detected arrangement of the accessory device, wherein applying the SAR mitigation algorithm comprises reducing a transmission power level of at least one of said antennas to maintain compliance with a legal limit established for SAR in case of user presence indications and enforcing a maximum transmission power level for each of the one or more antennas established with respect to the detected arrangement of the accessory device in case of no user presence indications.
