1. A method for determining a location of a computing device, comprising:
- collecting radio frequency (RF) information obtained by a plurality of cognitive radio devices having known locations;
receiving, from the computing device, a local RF fingerprint for radio signals detected by the computing device;
determining the location of the computing device by identifying a subset of the RF information matching the local RF fingerprint; and
upon determining the location of the computing device, providing the location to the computing device.

Abstract
Technologies are generally described herein for determining a location of a computing device using radio frequency (“RF”) information. Some example technologies may receive a local RF fingerprint for radio signals detected by the computing device. The technologies may determine a location of the computing device by identifying a subset of RF information matching the local RF fingerprint. The technologies may provide the location to the computing device.

27. A computer-readable medium having computer-executable instructions stored thereon which, when executed by a computer, cause the computer to:
-
collect radio frequency (RF) information obtained by a plurality of cognitive radio devices having known locations, wherein the plurality of cognitive radio devices are configured to scan radio frequencies over a continuous spectrum and identify underutilized radio frequencies in the scanned radio frequencies; receive, from a cognitive radio device over a communications network, a request for a location of the cognitive radio device, the request including a local RF fingerprint for radio signals detected by the cognitive radio device; determine the location of the cognitive radio device by identifying a subset of the RF information that matches the local RF fingerprint; and upon determination of the location of the cognitive radio device, provide the location to the cognitive radio device over the communications network. - View Dependent Claims (28)
