This article examines the most popular wireless local area network (LAN) schemes, including Wi-Fi, Ultra-Wideband, and Bluetooth. Portable electronic devices are everywhere. In fact, they are the fastest-growing segment of the electronics industry. All but the simplest devices need some way of quickly getting data in and out. In the beginning, there was Ethernet, using cable to connect LAN stations to a hub. In a wireless LAN, the cable is replaced by a radio channel, connecting stations to wireless access points.
