Smart Antenna Systems and Wireless LANs

This book concerns two major topics, smart antenna systems and wireless local-area-networks (LANs). For smart antenna systems, it d- cusses the mechanics behind a smart antenna system, the setup of a smart antenna experimental testbed, and experimental and computer simulation results of various issues relating to smart antenna systems. For wireless LAN systems, it discusses the IEEE 802.11 worldwide wi- less LAN standard, the operation of a wireless LAN system, and some of the technical considerations that must be overcome by a wireless LAN system designer. These two topics are combined in the discussion of the Smart Wireless LAN (SWL) system, which was designed to achieve the benefits which smart antenna systems can provide for wireless LAN systems while still remaining compatible with the 802.11 wireless LAN standard. The design of SWL calls for the replacement of the conv- tional wireless LAN base station (which are called access points in the 802.11 documentation) with an SWL base station, while leaving the - dividual terminal operation as unchanged as possible.

This book covers the design and mechanics of smart antenna systems and their compatibility with the worldwide wireless LAN standard (IEEE 802.11). Included are applications for Wireless LANs, terrestrial and satellite cellular systems, wireless data distribution systems, and other advanced systems. In-depth coverage is provided on utilizing smart antenna systems to increase network capacity, reduce the effects of channel fading, extend antenna battery life, and enhance the range of any wireless communications systems. The author has also included a wide range of testbed experimental results on diversity gain, LEO Iridium-like satellite emulation, as well as other advanced topics such as MAC and PHY layers, dynamic slot assignment, timing synchronization, and spatial signature properties of a smart antenna system. Many of these topics are being presented for the first time in an organized, readable book form. Smart Antenna Systems and Wireless LANs is a timely book for designers, engineers, and researchers of wireless communications systems.
