FCC’s 5 GHz spectrum initiative could mean more and wider channels for IEEE 802.11ac

Thursday, January 10th, 2013

FCC Chairman Julius Genachowski yesterday announced an initiative to make 195 MHz of more spectrum available for Wi-Fi in the 5 GHz band.

The last time more spectrum for Wi-Fi was made available in this range was in 2003, when an FCC increased the then 300 MHz bandwidth to 555 MHz. As the document in that last link shows, the 5 GHz band is not as neat as the 2.4 GHz band, with other services, such as radar, requiring protection. These coexistence issues will have to be looked at again.

Experimental Radio Applications at the FCC

Thursday, January 3rd, 2013

This summarizes a selection of applications for the Experimental Radio Service received by the FCC during September-December 2012. These are related to LF and HF propagation, cognitive radio, satellite telemetry, ultra-wideband (UWB), ground-penetrating and synthetic-aperture radar, mobile broadband, aerial communications (balloons), LTE, managed access, military communications, Wi-Fi, GPS, sensor networks, and MVDDS. The descriptions are sorted by the lowest frequency in the application.

Why I doubt FaceTime will crash mobile networks

Monday, August 27th, 2012

IntoMobile suggests mobile networks could “crash” or “crumple” under the pressure of FaceTime demand. I think they’ll be OK, mainly for cultural reasons.

Experimental Radio Applications at the FCC

Wednesday, July 18th, 2012

This summarizes a selection from 289 applications for the Experimental Radio Service received by the FCC during April, May, and June 2012. These are related to AM, high-frequency propagation, ultra-wideband, frequency-hopped VHF, managed access, small satellites, radar, MIMO, TV white space, low-power FM, stadium wireless service, GSM, and DTV. The descriptions are sorted by the lowest frequency found in the application.

Experimental Radio Applications at the FCC

Monday, April 2nd, 2012

This summarizes a selection of applications for the Experimental Radio Service received by the FCC during January, February, and March 2012. These are related to radar, Amateur Radio, spread spectrum, white space, spacecraft telemetry, propagation testing, satellites, smart grid, femtocells, machine-to-machine communications, ad hoc networks, 4G backhaul, electronic warfare, and robotics.  The descriptions are listed in order of the lowest frequency found in the application.

Experimental Radio Applications at the FCC

Wednesday, September 8th, 2010

This summarizes a selection of applications for the Experimental Radio Service received by the FCC during August 2010. These are related to radar, military communications, mesh networking, unmanned aerial vehicles, satellite services, biomedical telemetry, aircraft telemetry, safe-driving systems, geophysical sensors, electronic warfare, smart grid, and antenna testing.

  • INOVA Geophysical Equipment Limited filed an application (with supporting exhibits) to test a proprietary mobile radio system in the 30-36 MHz and 150-174 MHz bands. The radio links would be used to control remote geophysical seismic recording equipment, which INOVA manufactures. At the end of testing, INOVA plans to put the radio equipment into production and lease it to customers.

  • Fortress Technologies filed an application for experimental license to test several of its secure mesh-networking products developed for military applications. Several exhibits are included but they are not publicly available due to a confidentiality request. Operation is to be on 4.9425-4.9875 GHz.
