In this paper, we will discuss the use of smart antennas in wireless local area networks, WLANs. We will first discuss the issue of analog versus digital implementation of smart antennas and how smart antenna technology can be added to existing WLAN systems without modifying those systems. This presentation will examine current technologies for wireless networking in the home or enterprise, and will make a case for why smart antenna technology is needed. Performance results and extensions will be described, and future applications (beyond Wi-Fi to areas such as WiMax) of smart antenna technology will also be discussed.
