== 802.11x Wireless Connections ==

802.11x covers a set of IEEE standards which define wireless networking better known as Wi-Fi. A number of standards have evolved including 802.11a, 802.11b, 802.11g and 802.11.n. Until recently the concept of wireless networking involved computer systems talking to each other, but recent years have introduced a range of wireless devices (notably the iPhone from Apple) which will switch over from using a carrier based wireless connection to wireless access points (WAP) when they come into range.
