The goal of modern cellular mobile telephone systems is to provide wireless communication services to people as efficiently as possible. In the past, this definition would have been restricted to mobile telephone services. However, in new telephone service markets, the cost of wireless infrastructure is less than wired infrastructure. Thus wireless mobile telephony technology is being adapted to provide in-home telephone service, the so-called wireless local loop (WLL). Indeed, with approximately 2 billion subscribers worldwide in 2006, it appears that wireless telephony will become dominant over traditional wired access worldwide. More importantly, nonvoice services are proliferating rapidly, and mobile telephone technology is now being integrated into a wide array of personal, portable devices.
