Abstract
A wireless access point or other transmitter can be configured to inject a supplemental signal into a data modulated carrier signal. In some examples, a transmitter system includes an antenna, a primary modulator, and a supplemental modulator. The primary modulator receives a baseband data signal and a carrier signal and outputting to the antenna a data modulated carrier signal according to a communications protocol. The supplemental modulator injects a supplemental signal into the data modulated carrier signal by distorting the data modulated carrier signal within an error bound of the communications protocol. A corresponding receiving system includes an antenna and a supplemental signal detector for detecting the supplemental signal by detecting the distortion within the data modulated carrier signal.
