The tests will be on 703.55-704.45 MHz and 733.55-734.45 MHz. The equipment that Chevron proposes to test has been certified internationally, but not for the lower 700 MHz band in the United States. If the tests are successful, the equipment manufacturer will seek certification from the FCC. Chevron plans to use this equipment to enhance the capabilities of its point-to-multipoint WiMAX network and provide high-speed network connections to existing and future production platforms.
The Aerospace Corporation filed an application and exhibits for special temporary authority to operate a satellite link in support of research into the space application of microelectromechanical systems (MEMS) components and related microelectronics technologies. The test includes a demonstration of principles of the physics of the low-earth-orbit space environment and its effects on MEMS microelectronics. The satellite weighs 11 pounds and its dimensions are 5x5x10 inches. It’s to be deployed during the last space shuttle mission, STS-135, which is now scheduled to launch July 12. The satellite has two radios for redundancy, both operating on 914.7 MHz, and both using an omni-directional patch antenna.
The Maryland Department of the Environment filed an application and exhibits for experimental license to use wind-profiling radar to study the transport of air pollutants such as ground-level ozone. The radar is a boundary-layer profiler, and depends on the scattering of a transmitted signal by irregularities in the index of refraction of the air caused by turbulent eddies in the wind. By receiving the scattered signal and determining the Doppler frequency, the speed of the wind can be determined. The radar consists of a vertically-looking antenna subsystem, a transmitter subsystem capable of unmodulated and phase-modulated pulses, a receiver subsystem, a signal processing subsystem performing target parameter extraction and identification, and a data processing/communication subsystem for charting, recording, and transmitting results. Operation will be on 915 MHz at Cambridge, Maryland.
BAE Systems filed an application with exhibit for experimental license to operate on 1370-1390 MHz in Tucson, Arizona to test a new radio modem, transmitter, and receiver on the Silver Fox unmanned aerial vehicle (UAV) as part of a U.S. military project.
LightSquared filed an application and exhibits for special temporary authority to conduct testing to determine the effects of L-band LTE signals on GPS devices in a live field-test environment. The testing is an outgrowth of the requirements established in FCC Order DA 11-133 granting LightSquared, a Mobile Satellite Service (MSS) licensee in the L-Band, a conditional waiver of the Ancillary Terrestrial Component (ATC) “integrated service” rule. The requested frequency bands include 1526-1536 MHz and 1545.2-1555.2 MHz.
