Abstract: Systems and methods which provide white space channel identification and/or selection using high probability area determinations for a device and availability probability calculations for channels based on a probability model are described. A white space device (WSD) may utilize spectrum scanner sensing results to determine one or more course high probability area (HPA) for the WSD. The sensing results may further be analyzed to derive probability information regarding the WSD being located at the HPAs, to thereby refine the HPAs. Thereafter, the information regarding probabilities of the WSD being located at the HPAs may be utilized with information from a white space location database to determine an availability probability of one or more white space channels. One or more such white space channels may be identified and/or selected for use by the WSD.
