M2M (Machine-to-Machine) communication with the GM862 Quad Band Cellular Module by Telit. This module will allow you to connect your embedded device anywhere in the world where cell phones are used. This version (GM862-QUAD) is compatible with the various 850/900/1800/1900MHz frequencies of cellular networks across the globe.

The GM862 module is controlled via AT commands. This means all you have to do is send a string of serial characters such as “ATD 3035551234” and the module will place a call. No fuss, no mess. Once the module has connected to another module or modem, a serial connection is made and data can be transferred as simply as passing and receiving serial strings through the module or use TCP IP UDP or other protocols.
