>Description:
>As nations struggle to provide spectrum in a finite swath of useful
>spectrum, especially spectrum for use with wireless Internet bandwidth,
>there are problems with incumbents in a given band. The incumbents may
>use the spectrum inefficiently, especially geographically - there may
>be large swaths of country where a particular band is not used at all,
>and others where use is only in a portion of the band.
>
>Recently, techniques have been developed that attempt to share spectrum
>between incumbents and new users. The generic term for this is "white
>space". For example, in over the air TV bands, spectrum is divided into
>channels, and in any one area, usually not all channels have TV
>transmitters in range. There is a desire among many regulators to make
>this prime spectrum available for Internet access and other uses, as
>long as the new use does not interfere with the existing TV band use.
>
>Multiple database(s) are expected to exist which contains the
>information about available channels for use at a given location. A
>device is required to query the database for available channels and
>associated information. There are several scenarios that the US
>regulation permits which include a simple tower/client arrangement
>where the tower queries the database on behalf of itself and its client
>TVBDs as well as ad hoc mobile networks where at least one TVBD in the
>ad hoc net has another path to the Internet and can query the database
>with it.
>
>This BoF will explore the various aspects of specifying a messaging
>interface betwen the devices and the database.
