Power Control

What Does Power Control Mean?

In telecommunications, power control refers to the process of controlling the power of a transmitter to achieve better communication signal or overall quality of service. It is mainly used to control the transmitting power of a communication device to achieve better performance.


Techopedia Explains Power Control

Power control is primarily implemented via purpose-built algorithms. It is implemented on communication devices and systems such as wireless routers, cell phones, cellular networks, sensor networks, DSL modems, etc. Typically, power control allows the transmission or signal power to be scaled, which results in better signal quality. However, power control algorithms are also designed to not scale the power unnecessarily high. Therefore, power control keeps a balance between low, average and high transmission powers for optimal signal or system quality.
