Smart Antenna for Wi-Max Radio System
In simple words, smart antenna is such that it can sense its environment and can adjust its gain in different directions accordingly. The authors provide a smart solution to the problem of communication traffic overload, i.e., they increase the traffic capacity. They also improve the QOS. RF spectrum is a limited resource and is becoming crowded day by day due to the advent of new technologies. The sources of interference are increasing as well and hence interference is becoming the limiting factor for wireless communication. Smart Antenna adapts its radiation pattern in such a way that it steers its main beam in the DOA (Direction Of Arrival) of the desired user signal and places null along the interference.
