Abstract
The present invention uses an acoustic modem embedded in a remote device enhanced with automatic repeat request and forward error correction routines to provide reliable transfer of electronic messages from the messaging server to the remote device. This may provide significantly better error correction than standard PC modems. Also the present invention, may provide a fast, reliable connection sequence by use of a preamble frame. According to an embodiment of the present invention, a method of communicating messages between a messaging server and a remote device is provided. The method includes a variety of steps such as establishing a connection between the messaging server and the remote communication device by transmitting a preamble frame, exchanging data frames between the remote device and the messaging server, detecting and correcting errors in received frames, and re-transmitting received frames, if errors are uncorrectable.
