Wireless (802.11/Wi-Fi)

Overview

Wireless networking, predominantly Wi-Fi (based on the the 802.11x family of protoocls), allows any wireless enabled device to access a network easily and quickly, provided it's within 30m or so of the wireless access point.

Since any device that is Wi-Fi enabled can connect to the wireless access point - it is vital to use one of the wireless encryption algorithms, with a secret key, to prevent unauthorised access. Most Wi-Fi networks currently use the WEP algorithm. This is easily compromised, however, and the WPA or WPA2 algorithms are starting to supersede it.
