This is the first guide to wireless technology with the pedagogical breadth, depth, and discipline needed to help both professionals and students master the entire field. Legendary networking author William Stallings presents thorough, up-to-date introductions to every key aspect of wireless communications and networking: technology, architecture, types of wireless networks, design approaches, applications, standards, and more. Stallings begins with the fundamentals of data transmission: signals, channels, analog and digital data transmission, and multiplexing, circuit-switched and packet-switched networks, and the role of protocols such as TCP/IP. With these basics understood, he moves on to the unique components and technologies of wireless networks. The book includes detailed chapters on antennas and propagation; signal encoding techniques; spread spectrum; coding; and error control. Stallings offers in-depth coverage of satellite-based wireless networks; analog, TDMA, CDMA, and 3G cellular; cordless systems; Wireless Local Loop; Mobile IP; and WAP. The book also contains a full section of wireless LANs, including in-depth coverage of IEEE 802.11 and Bluetooth. An accompanying Web site includes PDF transparency masters, PowerPoint slides, and book updates. For all students and professionals in the fields of information technology, networking, and data communications -- including network designers, implementers, administrators, managers, and customers.
