ABSTRACT
Next generation wireless services are very broad in scope. They include a range of user devices, for example, a new generation of cell phones, personal digital assistants (PDAs) with voice and wireless data capabilities, laptop computers equipped with cards to receive and send wireless data, and a number of hybrid devices. They also include many ways in which wireless networks can be configured, including 2, 2.5, and 3G wireless networks, as well as wireless local area networks such as WiFi. In order to manage the scope of issues associated with wireless networks, this chapter excludes wireless networks that are used exclusively within an office building or home.
