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 summarizes a selection of applications for the Experimental Radio Service received by the FCC during February 13-20: landslide monitoring, WiMAX, earth-station antennas, radar, military mobile data, automatic aircraft landing, psyops transmission.
- Skyport Global Communications filed an application (with supporting exhibits) to test a 55cm slot-array X-band antenna manufactured by EMS Technologies on 8218-8400 MHz. The test will be done using a satellite link between the 55cm antenna in Atlanta, Georgia and a hub in Houston, Texas using the XTAR LANT X-band satellite.

This summarizes a selection of applications for the Experimental Radio Service received by the FCC during February 8-12: mobile satellite terminals, white space, smart grid, satellite infrastructure, submarine communications.
- Xtreme Hi-Tech files an application (with supporting exhibits) for experimental license to test a new type of mobile satellite antenna while it is mounted on an SUV. Operation it to be on 14.0-14.5 GHz in suburban Washington DC. Photos accompanying the filing show a Commtact mobile satellite terminal, which Xtreme Hi-Tech sells.
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)

University of Massachusetts applies to use WiMAX with virtual network lab
The University of Massachusetts has filed an application and supporting exhibit with the FCC for an experimental license to use WiMAX as part of the Global Environment for Network Innovations (GENI) project.
Operation will be at 2590-2600 MHz and use NEC’s WiMAX base-station hardware supporting a maximum of three sectors, a coverage radius of 3-5 km, and peak data rates of 15-30 Mbps. The base station uses an external PC controller that interfaces the base station to other parts of the GENI infrastructure.
GENI plans to support experimentation on shared heterogeneous infrastucture with programmability throughout the network, including wireless aspects. It is intended to promote innovations in network science, security, technologies, services, and applications. At this time, GENI plans to use WiMAX at 8 universities. Some sites will also use the OpenFlow standard, which allows researchers to run experimental protocols on production networks.
BAE applies to test navigation and collision-avoidance radar
BAE Systems has filed two applications with the FCC for experimental license. The first application and supporting exhibit is for testing, at 13.3 GHz, a re-design of BAE Systems’ ASN-128 Doppler navigation system used by the U.S. military. The re-design was needed because some materials used in the production of the antenna have been discontinued. Testing is to ensure that new materials have no adverse impact.
The second application and exhibit is to test, at 34.7 GHz, a radar collision avoidance system to be used by military aircraft, especially helicopters, at low altitudes to detect power lines and other structures that are close to the ground.
General Dynamics testing Integrated Wireless Network
General Dynamics submitted an application and supporting exhibit to the FCC to allow tests in support of the company’s Integrated Wireless Network, a nationwide trunked Land Mobile Radio system that is part of a government program. Various frequencies are requested including near 165, 770, and 800 MHz.
ADC applies to test WiMAX in Colorado
ADC Telecommunications has filed an application and supporting exhibit with the FCC requesting Special Temporary Authority to test a WiMAX (802.16e) pico base station in the 2.5 GHz range. Tested will be coverage, uplink communication, and throughput in the Greely, Colorado area. Testing is in conjunction with WiMAX operator Open Range Communications. ADC partnered with WiNetworks to design the base station.
