This summarizes a selection of applications for the Experimental Radio Service received by the FCC during March 31 – April 15, 2010. These are related to WiMAX, unmanned aerial vehicles, radar, cellular networking, rural broadband, ultra-wideband, satellite, software defined radio, white space, adaptive networks, and amplitude companded side band.
- Clearwire filed an application for special temporary authority (with supporting exhibits) to test WiMAX equipment at various locations in California on 2502-2568 MHz. The purpose of the test is to validate the ability of equipment to operate satisfactorily in the presence of collocated equipment licensed to Sprint in the 800 and 1900 MHz bands.
- DataSoft Corporation filed an application (with supporting exhibit) for experimental license. The company says it is developing a Software Defined Radio platform featuring a configurable 400 MHz to 4000 MHz transceiver intended for markets requiring an adaptable, programmable, or cognitive radio such as TV white space, smart grid, and home networking. The experimental license is to support testing of the transceiver in a TV white space application. Due to lack of available white-space client devices, the applicant proposes using re-banded Wi-Fi equipment in the experiment. Operation is to be in Scottsdale, Arizona on 500-540 MHz.
- BAE Systems filed an application (with supporting exhibit) for experimental license to test a wireless link for use by the US Army between a soldier’s night weapon sight and night vision goggles. The wireless link will utilize WiMedia MB-OFDM Ultra-wideband technology. Operation is to be on 3.168-4.752 GHz.
- Honeywell filed an application (with supporting exhibits) for experimental license to test integration of a direct digital radio link into small unmanned aerial vehicles. This is in support of two US Army programs and one US Navy program. The radio is manufactured by AeroVironment, Inc. Both command and control, as well as video downlink, utilize the same radio. Frequency bands requested are 1711.5-1721.5 MHz and 1755-1848 MHz. Operation will be in Albuquerque and Rio Rancho, New Mexico.
- Texas Tech University Wind Science and Engineering Research Center filed an application (with supporting exhibit) for special temporary authority to operate a Ka-band mobile radar systems in support of tornado research. Operation is to be at 34.86 GHz.
- Kestrel Signal Processing filed an application for special temporary authority to allow “testing of a novel cellular network technology that is compatible with standard GSM cellular handsets.” The operation will be on the grounds of, and overlap in time with, the Burning Man event held near Gerlach, Nevada Aug. 30 – Sept. 6, 2010. Operation will be on 869-894 MHz and 1930-1945 MHz.
- CenturyTel Broadband Wireless filed an application for special temporary authority to assess the performance of equipment manufactured by IPWireless (but not yet FCC type accepted) for providing 700 MHz rural broadband service. Operation is to be at Monroe, Louisiana on 736-746 MHz.
- Inmarsat Hawaii filed an application (with supporting exhibit) for special temporary authority to initiate a program of experimentation designed to facilitate the introduction of a new Broadband Global Area Network (BGAN) user terminal type. The testing would attempt to gain knowledge with respect to link quality and to validate Inmarsat’s theoretical approach. Testing also would evaluate the interaction of the new terminal type with Inmarsat’s ground infrastructure. Inmarsat proposes to test the terminal type in the 1626.5- 1660.5 MHz transmit band and 1525.0-1559.0 MHz receive band.
- Cobham Defense Electronic Systems filed an application (with supporting exhibit) for experimental license to operate in Lowell, Massachusetts on various frequencies between 902 and 5925 MHz. Apparently, this is to be experimentation in support of the DARPA program Wireless Network after Next (WNaN). As the exhibit explains, the WNaN “program goal is to develop and demonstrate technologies and system concepts enabling densely deployed networks in which distributed and adaptive network operations compensate for limitations of the physical layer of the low-cost wireless nodes that comprise these networks. WNaN networks will manage node configurations and the topology of the network to reduce the demands on the physical and link layers of the nodes. The technology created by the WNaN effort will provide reliable and highly- available battlefield communications at low system cost.”
- Radio Design Group filed an application (with supporting exhibit) for experimental license to test a wireless intercom system that will utilize an Amplitude Companded Side Band (ACSB) RF platform. The applicant expects this to provide a stable and robust signal that is efficient in terms of transmission bandwidth and power. The applicant also expects this system to allow for an occupied bandwidth of 15 kHz per audio path including guard band. The system will be tested on 174-216 MHz and 470-512 MHz in the vicinity of Grants Pass, Oregon.
