•Power control is the intelligent selection of transmit power in a communication system for achieving BEST performance within the system.
•The performance is depend on context and there are chances to include optimizing metrics like link data rate, network CAPACITY, geographic coverage and range.
•A higher transmit power TRANSLATES into a higher signal power at the receiver.
•The bit error rate will be REDUCES at the receiver of a digital communication link, by having higher signal-to-noise ratio.
•Higher transmit power provides more PROTECTION against a signal fade in a wireless fading channel.
