Wireless is the fastest growing segment of the communications market in the world. It has a wide range of services from satellites that provide low bit rates but global coverage and cellular systems with continental coverage to high bit rate local area networks and personal area networks with a maximum range of a few to a hundred meters. Using a cellular system is by far the most common wireless method to access data or perform voice dialing. In the near future, the authors will expect seamless global roaming across different wireless networks and ubiquitous access to personalized applications and rich content via a universal and user-friendly interface.
