How Power Control in GSM
Prolong battery life
Reduce network interference
Include both uplink power control and downlink power control
Level and quality are taken into account
BSC or BTS is the final adjudicator
During the process of radio transmission of signals, to reduce the interference, to increase the utilization efficiency of the frequency spectrum, and to prolong the battery life, the transmission power can be adjusted, that is called power control. More specifically, the power control refers to adjust the transmission power of the mobile station or base station in the radio mode within a certain range. Its objective is the same as that of the DTX. When the receiving level and quality is rather strong, the transmission power at the TX terminal can be reduced appropriately so that the communication can be kept at a certain level. In this way, the interference on other calls around can be reduced.
