Abstract
An electronic device may include an auxiliary circuit providing an operative function, a data signal circuit, and an extremely high frequency (EHF) wireless transmitter. The auxiliary circuit may produce a first low frequency data signal. The data signal circuit may be coupled to the auxiliary circuit for encoding a first composite data signal including the first low frequency data signal and the first base high frequency data signal. The EHF wireless transmitter may transmit the first encoded composite data signal to an external device over a wireless EHF communication link. The transmitted encoded composite data signal may have a predefined rate of carrier modulation.
