Experimental Radio Applications at the FCC
This summarizes a selection of applications for the Experimental Radio Service received by the FCC during February 21-26: radar, WiMAX, MVDDS, aeronautical communications, private mobile data, millimeter wave, high-frequency data, space communications, and radiolocation.
- The Maryland Department of the Environment filed an application (with supporting exhibits) to operate a wind-profiling radar on 915 MHz. The equipment was developed by the National Oceanic and Atmospheric Administration (NOAA) and fabricated by Radian International. The antenna is to consist of one steerable four-panel micro-patch phased array.
- DTV Norwich filed an application (with supporting exhibit) for special temporary authority to conduct propagation tests prior to potential full-scale deployment of Multichannel Video and Data Distribution Service (“MVDDS”) at 12.2 to 12.7 GHz in the Miami area. This is to determine the suitability of potential transmitter sites for full-scale operation, for which DTV Norwich has a license.
Experimental Radio Applications at the FCC
This describes a selection of applications for the Experimental Radio Service received by the FCC during January 30 through February 7: surveillance radar, airborne telemetry, mobile services, satellite, and amateur radio.
- Lockheed Martin filed an application (with supporting exhibit) for an experimental license to operate three models of ICx Radar System’s perimeter surveillance radar on 35.5 GHz for R&D and customer demonstrations. This will occur at various locations in the US, but primarily in Syracuse, New York.
- Honeywell filed an application (with supporting exhibits) for special temporary authority to operate in the 1625-1725 MHz range while integrating a new AeroVironment radio with an unmanned aerial vehicle used by the military. A key feature of the radio is that both command and control, as well as video downlink, can be accomplished using the same unit. Operation will be in New Mexico . There is concern about protecting the 1660.5-1668.4 MHz radio astronomy band, and discussions are ongoing.
Experimental Radio Applications at the FCC
This summarizes a selection of applications for Experimental Radio license, and for Special Temporary Authority, received by the FCC during January 21-25: radar, spacecraft telemetry, cognitive radio, modulation/demodulation techniques.
Raytheon Missile Systems files an application and supporting exhibit requesting Special Temporary Authority to use Freewave radios on an aircraft in support of a test to verify the accuracy and effectiveness of aircraft radar. The plan is to transmit the position information from the tracked aircraft to the tracking aircraft, and verify that the position information determined by the radar is in sync with the actual position of the tracked aircraft. (1.35-1.39 GHz)
