Wireless Local Area Networks (WLANs) have certainly advanced over the last 15 years, haven't they? WLANs have become commonplace in universities, airports, coffee shops, and other major public places. Decreasing costs of WLAN equipment has also brought the technology into many homes as well. In 1998, the WLAN market was estimated at about $.3 billion; by 2005 it was $1.6 billion, a more than 500% increase. Rapid growth is expected to continue for at least the next several years.

WLANs can be defined as short-range packet data communications between base stations and user terminals that permit data rates up to 54 Mbps for coverage in indoor hot spots. Direct communication between terminals is also possible. WLAN allows people working within the same building to access an intranet or the internet wirelessly.

OK, that describes what a WLAN does -- but there are all sorts of different standards that govern HOW a WLAN works, including IEEE 802.11 and alphabetical variants (WIFI), 802.16 (WIMAX), Bluetooth, HiperLAN (in Europe), and others still on the drawing boards or just entering the marketplace.

This page is intended to help guide you from the basic theory of WLANs, to the design of WLANs, through the selection of vendor hardware and system architecture, to discussions of WLAN security issues. We provide links to recent and not-so-recent news stories on WLANs, reference books available for purchase, and a wealth of free information on the Web! Please explore the links and topics below to gain a more complete understanding of today's WLAN Systems!
