System and method for communicating using an in-vehicle system

A method in a remote receiver station including an answering point device for communicating wirelessly with a mobile device, the method comprising:

• opening a communications connection with the mobile device;
• receiving, in a voice-band, a series of encoded packets, encoded using a fountain code encoding protocol, from the mobile device over the communications connection;
• and
• decoding the encoded packets;
• identifying a packet number associated with each encoded packet;
• associating each encoded packet with a corresponding vector using the packet number;
• arranging each encoded packet and corresponding vector in a matrix;
• and
• inverting the matrix to decode the encoded packets
• communicating a trigger signal over the communications connection to indicate a readiness to receive the series of encoded packets from the mobile device over the communications connection;
• and
• including a pre-determined binary pseudorandom sequence in the trigger signal.
