Wireless is the hottest communications technology. If you're designing wireless products and systems, don't miss the Wireless Systems Design Conference & Expo (www.wsdexpo.com), February 24-27 at the McEnery Convention Center in San Jose, Calif. In my opinion, this is the best wireless conference for getting the latest on short-range wireless products and applications. It covers the full range of wireless local-area networks (802.11a/b/g), Bluetooth, and special short-range technologies. You can also expect details about ultra-wideband (UWB), ZigBee, and radio-frequency identification, among other hot technologies. WSD will cover components like antennas, filters, and crystals, too. I'll be attending--hope to see you there!
