|---|---|---|
Readily available audio interfaces on mobile devices (speakers and microphones) can be used to communicate data over a short range without the need for expensive infrastructure, using the imperceptible upper audio band (16-20KHz) of frequencies. A multi-tone Frequency Shift Keying (FSK) modulation is proposed for communication over the upper audio band. Error rate performance results for Multi-tone FSK modulation over white Gaussian noise channels are reported. Test results with a prototype modem developed are given. A sensing and spectrum access mechanism for devices with audio interfaces is proposed using protocol sequences. |
