Addressing fundamental theoretical issues about future wireless networks, this book covers topics such as capacity-improvements theoretically attainable from spread-spectrum systems, and practical concerns associated with current networks such as signalling, implementation of GSM and CDMA networks, and implementation of packet-data services over wireless networks. As well as the contributions looking at specific technologies, there are a number which discuss more generic problems in mobile networks, including issues associated with hand-off, resource management, frequency re-use, mobility, signalling, and wireless-packet networks. The book covers a broad range of issues associated with wireless networks, and is intended for researchers and practitioners working in the field of wireless communications and networks.
