This proposal will install and maintain a programmable WiMax base station at one of the existing University of Colorado Wide-Area Radio Testbed (WART) wireless network sites. It will use a “GENI WiMax Base Station Kit” provided by Rutgers.

Current Capabilities

  • Base Station is installed at 40.007422,-105.263173 with 120-degree sector pointed towards true-North.
  • As of 6/17/2011, PHY-layer is operational and transmitting, putting 40 dBm into the antenna cable at 2.578 GHz (channel 308) 10 Mhz bandwidth.
  • Demodulation achieved with an Anritsu Spectrum analyzer both at the base of the antenna (CINR =~ 45 dB) and 100m distant in the main lobe (CINR =~ 43 dB).
  • Four other WiMax BSs have been deployed simultaneously and are owned/operated by the university. They are operating at 2.510 GHz (Channel 36), 2.520 GHz (Channel 76), and 2.530 GHz (Channel 116). As of May, 2011, these are transmitting and operational. Connectivity to city buses is currently being debugged.
