Abstract
Certain aspects of the present disclosure propose methods for determining power level of one or more transmitters based on a power level of a primary transmitter when the transmitters are located in close proximity of each other. The power levels may be determined such that a combined power of all the transmitters is compliant with regulatory radio frequency (RF) safety requirements. For certain aspects, power level of the lower priority transmitters may be determined utilizing one or more look-up tables. For another aspect, power level of the lower priority transmitters may be calculated using an algorithm based on the power level of the priority transmitter. In aspects, the power level of lower priority transmitters and the time duration for which the transmitters are active may be selected dynamically so that the time averaged power of the transmitters for a defined period of time falls below the RF exposure limit.
