1.1.
Scope
The @Track Air Interface Protocol is a digital communication interface based on printable ASCII
characters over SMS or GPRS which is used for all communication between the backend server
and the terminal. The backend server sends a command to the terminal and then the terminal
confirms with an acknowledgement message. If necessary, the terminal also sends report messages
to the backend server.
The purpose of this document is to describe how to build up the backend server based on the
@Track Air Interface Protocol.
