W-CDMA and cdma2000 for 3G Mobile Networks
At the time we were working on third-generation (3G) wireless systems at Lucent Technologies, we realized that there were not many books available on this topic. ITU-R had defined four 3G systems, and published a set of standards in 1999. In most cases, our only sources of information were these standards, which were necessarily quite elaborate and were not available as a single document. The purpose of this book is to fill that void and...

Performance modeling and analysis of bluetooth networks
Bluetooth is a recent wireless communication technology specifically intended for short range ad hoc networking. It was initially envisaged as a simple cable replacement technology to connect various mobile, portable, and fixed devices such as PDAs, mobile phones, laptops, and printers, but its use has soon spread to include various general purpose networking tasks, and a number of Bluetooth-enabled devices have appeared on the market. In...

802.11® Wireless Networks: The Definitive Guide
People move. Networks don't. More than anything else, these two statements can explain the explosion of wireless LAN hardware. In just a few years, the projected revenues from wireless LAN products will be in the billions of dollars. The price of wireless LAN gear has plummeted and continues to fall dramatically. Wireless LANs are now a fixture on the networking landscape, which means you need to learn to deal with them.

Whereas today’s expensive wireless infrastructure depends on centrally deployed hub-andspoke networks, mobile ad hoc networks consist of devices that are autonomously selforganizing in networks. In ad hoc networks, the devices themselves are the network, and this allows seamless communication, at low cost, in a self-organized fashion and with easy deployment. The large degree of freedom and the self-organizing capabilities make mobile ad hoc...

IP-Based Next-Generation Wireless Networks Systems, Architectures, and Protocols
Wireless networks are evolving into wireless IP (Internet Protocol) networks to overcome the limitations of traditional circuit-switched wireless networks. Wireless IP networks are more suitable for supporting the rapidly growing mobile data and multimedia applications. IP technologies bring the globally successful Internet service creation and offering paradigm to wireless networks, bringing the vast array of Internet services to mobile users...

Implementing 802.11, 802.16, and 802.20 Wireless Networks
Communication, a word that many associate with modern technology, actually has nothing to do with technology. At its core, communication involves nothing more than the spoken or written word, and symbolic languages like art and music. Technology has become synonymous with communication because technology has historically been the method by which communication to or by the general population takes place. From the printing press to the...
