Abstract

Systems, methods, and apparatus are provided for device sensing in white space, by identifying, classifying and cataloging sources of signal emission based on radio frequency measurements. In an embodiment, signal emission devices are analyzed by automatically detecting signals, analyzing signals, comparing signal data to historical and reference data, and creating corresponding unique signal profiles. The detected, analyzed and compared data may be presented to a user.
