Filling the Spectrum Pipeline

In my last post I looked at how the U.S. is behind some other countries in having new mobile broadband spectrum in the pipeline, according to a tally prepared by CTIA. What’s the status of candidate new bands?

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.

Experimental Radio Applications at the FCC

This summarizes a selection of applications for the Experimental Radio Service received by the FCC during August 2010. These are related to radar, military communications, mesh networking, unmanned aerial vehicles, satellite services, biomedical telemetry, aircraft telemetry, safe-driving systems, geophysical sensors, electronic warfare, smart grid, and antenna testing.

  • INOVA Geophysical Equipment Limited filed an application (with supporting exhibits) to test a proprietary mobile radio system in the 30-36 MHz and 150-174 MHz bands. The radio links would be used to control remote geophysical seismic recording equipment, which INOVA manufactures. At the end of testing, INOVA plans to put the radio equipment into production and lease it to customers.

  • Fortress Technologies filed an application for experimental license to test several of its secure mesh-networking products developed for military applications. Several exhibits are included but they are not publicly available due to a confidentiality request. Operation is to be on 4.9425-4.9875 GHz.
