A study commissioned by UK telecom regulator Ofcom examines tradeoffs among many mobile indoor-coverage technologies, and suggests the agency help consumers learn more about them.
This summarizes a selection of applications for the Experimental Radio Service received by the FCC during April and May 2011. These are related to TV white space, electromagnetic compatibility testing, train control, point-to-multipoint communications, satellite communications, radar, unmanned aerial vehicles, GPS, ultra-wideband, mobile satellite service, UMTS, mobile broadband picocells, wireless backhaul, and IEEE 802.11p. The descriptions are sorted by frequency.
Recent contributions to the mobile broadband spectrum debate are reports from NAB and CTIA. I envisioned a “dueling reports” piece, but they mostly complement each other. Below I walk through the main points, adding some of my own views.
This summarizes a selection of applications for the Experimental Radio Service received by the FCC during March 2011. These are related to VHF propagation, satellite communications, TV white space, military communications, radar, software defined radio, aircraft broadband services, adaptive networks, peer-to-peer networks, intermodulation testing, unmanned aircraft systems, maritime broadband communications, border surveillance, target acquisition, and millimeter wave propagation. The applications are sorted by frequency.
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.
