Setting SAR exposure limit of mobile devices
Abstract:
A programmable controller and software that monitors periods an RF transmitter is active and a output power level during those periods of activity. These two values are multiplied together and accumulated over time to provide a value for the RF emissions for some period. A limit is set for the RF emissions for any period and if the RF emissions exceeds (or is expected to exceed given the current rate) the set limit, the system limits the subsequent emissions to not exceed the set limit. This reduction in emissions rate come at the cost of a small performance reduction.
