Abstract
Aspects of the present disclosure teach decreasing, in a time-averaged regime, the amount of RF energy emitted by a communications device. Generally speaking, the network tells the communications device what power level it should transmit at. If, however, the device determines that it would exceed an emission standard by transmitting at the specified power level for as long as it needs to in order to carry out its transmission duties, then the device can instead decide to transmit at a lower power level. Alternatively (or in combination), the device can, instead of transmitting all the time while it has data to send, only transmit intermittently. In either case, the emitted electromagnetic energy, as averaged over a period of time, is reduced below the maximum allowed by the standard. Later, if possible and necessary, the device can again transmit at a higher power level or more frequently.
