Smart Antenna Systems and Wireless LANs Background for Smart Antenna Systems IEEE 802.11 Wireless LAN Standard Smart Wireless LAN System Design Experimental Setup for Smart Antenna Systems Experimental Setup for Smart Antenna Systems Computer Simulation Results Conclusion. 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.
