Patent ID: 7848358

Claim:
A method of sending a data communication over a wireless digital voice communication network which transmits voice communications in voice frames, each of which contains a digitized segment of a voice communication in a voice frame format, the method including the steps of: (a) encoding the data communication into data frames having the same format as the voice frame format, by substituting each data code word of the data communication with a complex waveform construct assigned as a signature for the data code word to provide a sequence of complex waveform constructs, and subjecting the sequence of complex waveform constructs to voice encoding to encode the data into a plurality of data frames having the same format as the voice frame format and to be handled as voice frames for transmission over the wireless digital voice communications network; (b) transmitting the data frames over the wireless digital voice communications network; and (c) decoding the data frames to reconstruct the data communication.
