The Wireless MNS, also known as Wi-Fi (Wireless Fidelity), provides Internet access to mobile computers without connection cables. Instead, it uses radio communication between the computer and Access Points.
There are several versions of wireless Ethernet in use today. Columbia's wireless Ethernet is based on the IEEE 802.11b "high rate" standard, therefore only devices that use this protocol (such as Lucent's Wavelan PC cards and Apple's Airport, and many other devices which work on Microsoft Windows and Linux platforms) will work on the Columbia campus.
