The complete guide to CDMA and to its breakthrough digital cellular and PCS
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,
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
