Abstract:
1. A processor implemented method of wirelessly receiving data, comprising: receiving on a sonic transducer of a receive device sensitive to a wide frequency range of sound, data modulated over one or more sonic carrier signals traveling through air and transmitted as audible or inaudible sound over the wide frequency range of sound from a transmit device along with ambient sound within a geographic location; selecting one or more sonic transmission frequencies from a set of audible or inaudible sonic transmission frequencies for demodulation that reduce the probability of conflict with sonic transmission frequencies present in the ambient sound of the geographic location; configuring the receive device, in receipt of the one or more sonic carrier signals transmitted as audible or inaudible sound, to perform demodulation of the data at the selected one or more sonic transmission frequencies; and demodulating the data carried by one or more sonic carrier signals in the audible or inaudible sonic transmission frequencies in accordance with a sonic modulation protocol.
