CU Wide-Area Radio Testbed

The CU Wide-Area Radio Testbed (CU-WART) is a testbed maintained by the Computer Systems research group in the Department of Computer Science.

The testbed was initially used to deploy WiFi access points coupled with an analog phase-array antenna system manufactured by Fidelity-Commtech as part of a series of NSF-funded grants on routing and MAC layer design in networks with directional antennas.

In addition, testbed locations were used to deploy WiMax equipment as part of the NSF GENI wireless system in conjunction with Rutgers Winlab.

More recently, the infrastructure of the testbed is being used for wireless measurement hardware in collaboration with the Institute for Telecommunications Sciences at the National Telecommunications and Information Agency (NTIA/ITS). This resource is part of a cooperative research agreement between the University of Colorado and NTIA/ITS. That project enables measurement of wireless spectrum and system occupancy and spectrum utilization, testing and evaluation of spectrum sharing scenarios, and validation of radio wave propagation models. It also will help to develop early interference detection, interference mitigation, and spectrum forensics techniques.
