Abstract
Embodiments described herein provide a method and apparatus for determining a maximum transmitter power for a mobile device. First, a maximum specific absorption rate (SAR) value is determined. Then, a maximum transmitter power based on the maximum SAR value is determined. The maximum SAR value may be determined using any or all of the following methods: using a composite worst-case SAR map, determining a usage position of the mobile device, and a running average of transmitter power. A further embodiment provides an apparatus for managing transmitter power. The apparatus includes a modem that is in communication with a transmitter; a processor in communication with the modem; and a memory in communication with the processor.
