Good News on the White Space Front

It what has to be a positive move the FCC has released a query for suppliers for a database platform and service that will be part of the whole infrastructure. —

On November 4, 2008, the Commission adopted a Second Report and Order and Memorandum Opinion and Order (Second Report and Order) in ET Docket 04-186 that established rules to allow new, sophisticated, unlicensed wireless devices to operate in broadcast television spectrum at locations where that spectrum is unused by licensed services.1 This unused TV spectrum is commonly referred to as television “white spaces.” The rules will allow for the use of unlicensed TV band devices in the unused spectrum to provide broadband data and other services for consumers and businesses.

To prevent interference to authorized users of the TV bands, TV band devices must include a geo-location capability and the capability to access a database that identifies incumbent users entitled to interference protection, including, for example, full power and low power TV stations, broadcast auxiliary point-to-point facilities, PLMRS/CMRS operations on channels 14-20, and the Offshore Radiotelephone Service. 2 The database will tell a TV band device which TV channels are vacant and can be used at its location. 3 The database also will be used to register the locations of fixed TV band devices and protected locations and channels of incumbent services that are not recorded in Commission databases.4 The Commission decided in the Second Report and Order to designate one or more database administrators from the private sector to create and operate TV band database(s), which will be a privately owned and operated service. Database administrators may charge fees to register fixed TV band devices and temporary broadcast auxiliary fixed links and to provide lists of available channels to TV band devices.

Why a database is needed for a broadband low power spread spectrum channel? Well multiuse. The band(s) in some cases will have public service users in some areas. So any smart device must be able to discern that they reside in the same locale with say a fire dept siting on the open band between formerly CH 10-11. With that knowledge a smart device can map around and use other channels.

Its good news though. It means that finally the FCC is looking to see that white space systems are brought online. Personally I hope the Hams get in the act. We could see some wonderfully weird devices using the airwaves that might show commercial usage.

Linky.
