1. A method for verifying accuracy of geo-location databases in a cognitive radio communication system comprising of a plurality of protected entities and a plurality of secondary devices, the method comprising: registering the plurality of secondary devices at one or more geo-location databases, wherein the one or more geo-location databases maintain a list of available channels from a plurality of channels, reserved for the plurality of protected entities, for communication by the plurality of secondary devices, and wherein the protected entities are licensed users of the cognitive radio communication system and secondary devices are unlicensed users of the cognitive radio communication system; determining at least one geographical location to access; accessing at least one geo-location database with said geographical location, to obtain database results; comparing the obtained database results to a reference result; and establishing an error condition for any comparisons that exceed an allowed pre-determined difference.

The method of claim 1 , wherein the step of establishing further comprises allowing a pre-determined difference to exist between the database results and the reference results within a pre-determined spatial distance limit without establishing an error condition.
