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: CORNET3D, a web application developed by Nikita Sharakhov using WebGL, provides a 3D view of the CORNET testbed with information on which nodes and radios are operational. The application can also display 2D and 3D plots of the spectrum, which is sensed by the radios in real time. CORNET3D can teach students about strategies for optimal use of spectrum resources through a game—by providing them with real-time scoring based on their choices for radio transmission parameters. 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..
