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.

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.
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.
