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 14-20: VSAT for Haiti, helicopter surveillance in Chicago, WiMAX, wideband at high frequencies, avionics, cell phone jamming, and radar.

Intelibs requests Special Temporary Authority to study WiMAX coverage and user experience in Stony Brook, New York. Equipment is from Korean Telecom operating on 2624.25-2640.25 MHz.

Harris files an application and supporting exhibits for Special Temporary Authority to test a wideband waveform operating at either 12 kHz bandwidth or 24 kHz bandwidth to allow faster data transfer at high frequencies (3171 to 14550 kHz). The FCC objects to some of the proposed frequencies.

The City of Chicago files an application and supporting exhibits requesting Special Temporary Authority to test a new helicopter-based wireless surveillance system using a Chicago Fire Department helicopter. The test would use a FLIR analog video camera, encoder, Firetide wireless mesh router, Troll Systems antenna, and several ground sites with Firetide radios. (4940-4990 MHz)

Skyport Global Communications has requested, and been granted, Special Temporary Authority to test X-band VSAT portable units for use in support of disaster relief by the United States Air Force Rome Air Development Center. The operation includes emergency communications in Haiti using the XTAR LANT satellite, a 4.8m hub in Houston and 1.2m portable VSAT units in upstate New York. The portable units will eventually be shipped to Haiti. (8324-8331 MHz)

Inlustro Tech requests Special Temporary Authority to test cell phone jamming technology in Puerto Rico in the 800-2100 MHz range. The FCC has requested more details.

Innovonix files an application and supporting exhibits for an Experimental Radio license to test radar on 35-36 GHz in sensor systems capable of detecting objects in foliage. The radar uses an agile beam steering deflector. The testing will focus on improving the linearity of the FM sweep used for the modulation of the carrier, address a saturation issue that can occur in the front end when high energy is received, and possibly test a dielectric lens to be used in conjunction with a horn antenna. The FCC requested more details, and Innovonix responded.

Rockwell Collins files an application and supporting exhibits for Experimental Radio license to test the DME-2100, a transponder-based radio navigation technology for air transport that measures distance by timing radio propagation delay. The request is for operation on 1025-1150 MHz, and the FCC has asked Rockwell Collins to coordinate some frequencies with the FAA.

Ducommun Technologies requests Special Temporary Authority to test a low power doppler vehicle speed radar to be used at the side of the road to measure vehicle speed in different lanes. (34.5-34.9 GHz)
