Maximum power is consumed when the wireless device is transmitting and hence, transmission power is one of the important resources in wireless communication. Transmission power of a transmitter can neither be too low that the intended receiver cannot decode the signal nor can it be too high that it causes very high interference for other wireless devices in the network. The interference in wireless networks can be broadly classified as Co-Channel Interference (CCI) and Adjacent Channel Interference (ACI). Transmission Power Control (TPC) is one of the techniques used to control CCI and ACI. Power control algorithms used for TPC serve many purposes which include managing data quality, maximizing cell capacity, minimizing mean transmission power, and the like.
