TV White Space Database Assisted Locationing For TV Band Devices
Abstract:
A method and system for obtaining an available white space channel for wireless communication using a white space device (WSD) are described. The WSD scans signals of TV transmitters, determines the received signal strength (RSSI) for those signals, and records TV data, including TV designations and corresponding RSSIs, for signals that exceed a predetermined threshold. The WSD sends TV data for at least three TV transmitters to an enhanced TV white space database (EnTVDB). The EnTVDB uses the TV data and information in its database to determine the geo-coordinates of the WSD. The EnTVDB uses the geo-coordinates of the WSD to identify available white space. The EnTVDB sends at least one channel of available white space to the white space device for its wireless communication.
