Abstract
A radiation power level compliance and control scheme for a wireless user equipment (UE) device including one or more tunable elements. The wireless UE device comprises a component configured to detect one or more changes with respect to at least one operational parameter associated with the wireless UE device. A component is provided for determining that a tunable action is required with respect to at least one of the tunable elements. Upon defining one or more tunable element settings, a component is configured to determine a Specific Absorption Rate (SAR) value, which is compared against an acceptable limit. If the SAR is within the limit, appropriate tuning control signals are provided to the tunable elements according to the defined tunable element settings. If the SAR is not within the limit or is about to exceed the limit, then the tunable element settings may be changed and retested.
