The Georgia Tech LAWN (Local Area Walkup & Wireless Network) is designed for students, faculty, staff, and Institute guests who are mobile computer users. Mobile users may have wireless-enabled laptop computers, PDAs, phones, or similar devices. The LAWN gives mobile users network access to the Internet and campus information technology services similar to that which is available from a lab, campus office, or student residence hall.

All LAWN users are required to authenticate using their Georgia Tech account and password prior to communicating with the campus network or the Internet. There are two different networks (SSIDs) available based on the type of authentication method used. GTwpa uses 802.1x to authenticate clients before they are placed on the network.  Clients which do not support WPA should use GTwireless which supports redirection to a website (captive portal), as well as 3rd party authentication by MAC address, and the campus VPN.

Nearly every building on all three Georgia Tech campuses has wireless coverage, including all classrooms and most labs and common spaces. The Atlanta campus has full coverage in all residence halls, as well as significant coverage of outdoor walking paths, benches, bus stops, and bus routes. Many campus locations – classrooms and the library for example – also provide wired LAWN ports.

Most wireless access points on campus support 802.11a/b/g, and a growing number support 802.11n including the library, and all classrooms on the Atlanta campus.

Visitors to campus are able to use commercial wireless network access (GTvisitor), which is available on the Atlanta and GT Savannah campuses.
