1. A mobile device comprising:
- a wireless telecommunication network access component (NAC) for communication via a wireless telecommunications network;
an in-band signaling modem coupled to the NAC to provide data transfer over a voice channel connection of the wireless telecommunications network, the in-band signaling modem including an input for receiving current location data, and an encoder for converting the current location data into audible tones that synthesize frequency characteristics of human speech and prevent voice encoding circuitry in the telecommunications network from corrupting the digital data represented by the synthesized audio tones; and
a GPS receiver to determine current location data of the mobile device, the GPS receiver coupled to the in-band signaling modem to provide current location data of the mobile device over a voice channel connection of the wireless telecommunications network.

Abstract
An inband signaling modem communicates digital data over a voice channel of a wireless telecommunications network. An input receives digital data. An encoder converts the digital data into audio tones that synthesize frequency characteristics of human speech. The digital data is also encoded to prevent voice encoding circuitry in the telecommunications network from corrupting the synthesized audio tones representing the digital data. An output then outputs the synthesized audio tones to a voice channel of a digital wireless telecommunications network.
