Abstract
Allocating spectrum to a secondary radio device includes determining a contour separation distance for the secondary radio device. The contour separation distance is a function of a minimum separation distance from protected areas of primary radio devices and an accuracy variance for the secondary radio device. The accuracy variance is specified as a distance and is a function of accuracy information for a reported location of the secondary radio device. If a distance between a contour of a protected area for a primary radio device and the reported location for the secondary radio device is less than the contour separation distance, a channel used by the primary radio device is not available for use by the secondary radio device for wireless communications. Otherwise the channel used by the primary radio device is available for use by the secondary radio device for wireless communications.
