    Google's TV white space database approved for operation - FierceBroadbandWireless (click for full article)

    by Tammy Parker - June 28, 2013

    "Google's (NASDAQ:GOOG) TV white space (TVWS) database system won approval for operation from the FCC's Office of Engineering and Technology.

    TVWS supporters such as Google contend the unlicensed spectrum is suitable for bringing cost-effective broadband service to rural and remote areas in the United States and around the world. The FCC has authorized use of five spectrum blocks for TVWS operations: 54 to 60 MHz, TV channel 2; 76 to 88 MHz, TV channels 5 and 6; 174 to 216 MHz, TV channels 7 to 13; 470 to 608 MHz, TV channels 14 to 36; and 614 to 698 MHz, TV channels 38 to 51.

    Database systems such as Google's, which provides a list of available TVWS channels, are necessary to support unlicensed radio devices transmitting in the spectrum bands used by broadcast television. In order to avoid creating interference, TV band devices (TVBDs) must contact an authorized database system to obtain a list of channels that are available at their individual locations and operate only on those channels.

    Google white space broadband plans get boost with FCC approval - SlashGear (click for full article)

    by Chris Davies - June 29, 2013

    "Google's plans to squeeze wireless internet access into the "white space" in-between TV channels - and in turn further prise web control from ISP dominance - has received a boost, with its TV bands database system getting the green-light from the FCC. The TV white space (TVWS) database, which lists the existing TV services along with the frequencies they operate on in each area, and as such highlights the spare spectrum where other services could operate, gained FCC approval this week, after having been run in a public trial from March.


    Google's aim is to promote what's known as dynamic sharing of spectrum, where chunks of bandwidth are used for multiple purposes at different times. That way, more applications can be derived from the limited amount of spectrum available.


    "If a government communications system does not require spectrum at specific times, that spectrum can be freed up for commercial purposes during those times" Google suggests. "With dynamic sharing, multiple users, including federal, non-federal and commercial entities, can all access available bands of radio spectrum."
