Abstract:
1. A method of operating a white space sensing device, comprising: receiving a geo-location information which is input by a user; communicating the geo-location information to a variable resolution geo-location server via a communications link; receiving a location indicator from the variable resolution geo-location server via a communications link, the location indicator representative of the location of the device; providing the location indicator to a white space database front end to request a white space channel list from the white space database front end; analyzing the white space channel list to determine whether there are any white space channels indicated as empty; if there is a white space channel which is indicated on the white space channel list as empty, storing the status of that channel as available for transmissions; analyzing the white space channel list to determine whether there are any white space channels indicated as a channel where signals can be reliably detected by the device; sensing the white space channel indicated as a channel where signals on the white space channel can be reliably detected by the device to determine if any signals can be detected on the white space channel; if no signals are detected on the white space channel, storing the status of that channel as available for transmissions; and transmitting signals on one or more of the channels with a stored status of available for transmissions.
