Over the past two decades, the demand for wireless service has grown at an extraordinary pace. The industry has grown from pagers, and cellular phones to Personal Communication Systems (PCS) and Wireless Local Area Networks (WLANs), providing services that deliver voice, data, and video in real time. For some time, wireless communications have been evolving from voice and low data rate services towards high bit rate services like video-telephony and multimedia (Fleury & Leuthold, 1996). In addition, wireless-in-house communications with a high degree of mobility are also emerging rapidly.
