Experimental Radio Applications at the FCC

This summarizes a selection from 289 applications for the Experimental Radio Service received by the FCC during April, May, and June 2012. These are related to AM, high-frequency propagation, ultra-wideband, frequency-hopped VHF, managed access, small satellites, radar, MIMO, TV white space, low-power FM, stadium wireless service, GSM, and DTV. The descriptions are sorted by the lowest frequency found in the application.

NTIA looks at Contraband Cell Phones in Prisons

Contraband cell phones are sometimes used by prisoners to talk to a child after school, for Facebook updates, or to post videos to YouTube. Other times they’re used to plan strikes, organize escapes, and order executions. Prisoner-directed crimes will occur with or without wireless, but cell phone access reduces barriers to them, and it’s a growing problem.

Experimental Radio Applications at the FCC

This summarizes a selection of applications for the Experimental Radio Service received by the FCC during September 2010. These are related to radar, military communications, ad hoc networks, GPS, avionics, WiMAX, maritime identification systems, TETRA, public safety, land mobile interoperability, prison cellphone management, air-ground radiotelephone service, picocells for cable systems, transportable satellite antennas, unmanned aircraft systems, consumer satellite terminals, and low-profile satellite antennas.

  • Northrop Grumman filed an application for special temporary authority in support of airborne experimental testing of the STARLite Tactical Radar System a small, lightweight (65 pounds) radar used for tactical reconnaissance by Unmanned Aerial Systems. Transmissions will be between 16.2 to 17.3 GHz. The radar has three modes: Synthetic Aperture Radar (SAR), Ground Moving Target Indicator (GMTI), and Maritime Moving Target Indicator. In the SAR mode, the radar imagery can be one of three forms: parallel to the aircraft flight vector, along a specified ground path independent of the aircraft flight path, or a higher-resolution spot image. In the GMTI mode, the radar provides moving target locations overlaid on a digital map. The MMTI mode performs a similar function for targets over water.

  • DRS Tactical Systems, a supplier of rugged computer equipment for military environments, filed an application (with supporting exhibit) for experimental license to test a mobile radio gateway. In the test, the mobile node will be a High Mobility Multipurpose Wheeled Vehicle (Humvee) with a mast. Equipment will be Harris model RF-7800W-OU440 broadband Ethernet radios attached to a DRS gateway system. This system is intended aid military and commercial entities by providing complex gateway functionality while in motion. Operation will be on 4.94-4.99 GHz.
