by Prof. Brian L. Evans, Interference management has become key in increasing communication system capacity. In cellular systems, increases in capacity have been and continue to be achieved primarily through aggressive frequency reuse by making cells smaller in area, e.g., through the more recent use of picocells and femtocells. Frequency reuse, in turn, increases interference in neighboring cells. In the 2.4 GHz band, a Wi-Fi system experiences interference from microwave ovens, the computational platform, leakage from WiMax transmissions, and other Wi-Fi networks.
