Claim:
1. A system comprising: an antenna; a primary modulator for receiving a baseband data signal and a carrier signal and outputting to the antenna a data modulated carrier signal according to a communications protocol; and a supplemental modulator for injecting a supplemental signal into the data modulated carrier signal by distorting the data modulated carrier signal within an error bound of the communications protocol, wherein distorting the data modulated carrier signal within the error bound of the communications protocol comprises distorting the data modulated carrier signal by an amount smaller than a violation threshold amount specified by the communications protocol used by the primary modulator; wherein the system is configured as a wireless access point for the communications protocol between a data communications network and a mobile device; and wherein distorting the data modulated carrier signal within the error bound comprises distorting the data modulated carrier signal during an initialization sequence for the wireless access point and ceasing distorting the data modulated carrier signal after the initialization sequence for the wireless access point.
