Ouvrage 0-13-572157-1 : APPLICATIONS OF CDMA IN WIRELESS PERSONAL COMMUNICATIONS
The complete guide to CDMA and to its breakthrough digital cellular and PCS applications.
In the United States, Code Division Multiple Access (CDMA) is
expected to become the most widely-deployed technology for the new generation of wireless Personal Communications Systems (PCS). In
this book, leading CDMA experts from Lucent Technologies' Bell Laboratories and from Bellcore present a complete engineer's guide to CDMA and its applications.
The book provides background on spread spectrum technologies, and
then offers an in-depth technical explanation of how CDMA
implements spread spectrum techniques. The CDMA architecture and
protocols are covered in detail, including:
The CDMA air interface (TIA IS-95A call processing model,
service configuration, negotiation, and registration)
Mobile Switching Centers (MSCs)
How CDMA maps to the 7-layer OSI reference model
The book includes thorough guidance for engineers about how to
design CDMA systems for optimal RF coverage. It provides CDMA
indoor and outdoor propagation models, CDMA link budgets,
guidelines for transitioning from analog to CDMA, facilities engineering information, radio link capacity, and techniques for handling "border
cells" near inter-vendor boundaries. An extensive case study is also included, presenting the design of a real-world CDMA system.
The book shows how CDMA networks are operated and maintained,
focusing on aspects of the telecommunications Network Management (TMN) architecture that lend themselves to management of PCS
networks. Finally, it describes future directions for CDMA and PCS
networks, including wireless intelligent networks, Over-the-Air Service Provisioning, improved speech coding, and CDMA-based digital data.
