The Cognitive Radio Network Testbed (CORNET) is a collection of 48 software-defined radio nodes deployed within a four-story building, Kelly Hall, on Virginia Tech's main campus. CORNET is an open-source platform for research and education in cognitive radio and related fields. It provides a unique collection of resources through a combination of flexible RF front ends, open-source software and FCC experimental licenses.

The CORNET nodes are remotely accessible. Register here for setting up an account and start using CORNET.

Note: This 3-D graphic was designed by Nikita Sharakhov using WebGL. You must use either Mozilla Firefox, Google Chrome, or Opera to view the 3-D Graphic. IE9 will support WebGL with the additional plug-ins InstantReality plug inFlash 11, or Chrome Frame. Use your mouse to rotate the graphic for a complete view of the testbed floors and nodes.
