内容简介：
A guide to the underlying technologies, key selection criteria, and design and deployment processes behind wireless local loop systems. This reference aims to help the reader develop a sound understanding of WLL system design procedures and provides practical guidance on choosing the best WLL and access technologies. It discusses the main areas of the telecommunications environment and the concepts of convergence and access technologies. The reader should learn why WLL is challenging the use of traditional copper cable, and the economic issues behind wired and wireless interconnection. Sections identify and describe key WLL parameters, including range and capacity; discusess critical customer service issues; examine the CDMA/TDMA debate and consider which represents a better access technique; evaluate various access technologies and guide the reader in the selection process; detail the network deployment process; show how to target effectively telecom service; and describe how to apply for a license, choose a service offering and develop the business case.
