Target Audience: Information technology professionals. About the Technology: Enhanced wireless support in Windows operating systems began in Windows 2000 with the addition of media sense capabilities in the Windows 2000 TCP/IP protocol, making it easier to roam from access point to access point without concern for loss of connectivity and having to reconfigure wireless settings. The Windows 2000 Network Driver Interface Specification (NDIS) interface supports wireless network adapters and their drivers. Several drivers for wireless LAN cards ship in Windows 2000 and most wireless LAN devices provide drivers for Windows 2000, making it easy to set up and use wireless devices with the operating system. Most of the wireless devices supported in Windows 2000 implement security using a pre-shared key and the data is encrypted with Wired Equivalent Privacy (WEP). With Windows XP, the addition of IEEE 802.1X to the operating system along with other zero configuration and roaming enhancements makes the Wi-Fi (IEEE 802.11b) wireless experience even more secure and seamless.

Wireless LAN - A wireless LAN or WLAN is a wireless local area network that uses radio waves as its carrier: the last link with the users is wireless, to give a network connection to all users in the surrounding area. Areas may range from a single room to an entire campus.

Wireless network interface card - A Wireless Network Interface Card (WNIC) is a network card which connects to a radio-based computer network, unlike a regular network card (NIC) which connects to a wire-based network such as token ring or ethernet. A WNIC, just like an NIC, works on the Layer 1 and Layer 2 of the OSI Model.

Cingular Wireless GoPhone - GoPhone is the trademark for Cingular Wireless' pay as you go service. Unlike many other PAYG services when GoPhone was aquired by Cingular they began to offer two options: The first is a conventional card-based PAYG service, where the customer purchases a reload card with a given number of minutes on it, which is based on the original service offered by AT&T Wireless.

Comparing WLAN and LAN - Wireless networks (WLAN) have become common in organisations and home use. The price of the wireless equipment is no longer a problem for home users.
