This text begins by looking at economic and cost issues associated with personal communications services. While cellular telephones and codless telephones have attracted the largest number of people to wireless communications, many predict that mobile computing and wireless data services are due for dramatic growth. Technical issues related to these applications are the focus of the book's second section. This is followed by a section on CDMA capacity increases, exploring sophisticated signal processing approaches to enhancing code division multiple access communications. Multiple access is then treated, followed by a section on radio resource management, which presents a set of complex and crucial tasks to be performed in future systems. The final section of the book examines the relationships of advanced wireless networks to fixed networks providing advanced communications services. This work can act as a reference for all those interested in the subject, and may be used as the text for advanced courses on the topic.
