The GM862-Quad module is the next generation of the GM862 product family continuing Telit’s success in the field of easy-to-integrate GSM/GPRS modules for all industrial m2m applications.
The development focus of the GM862-Quad was on pin-to-pin compatibility to existing GM862 products, while adding quad-band functionality and RoHS compliance. This translates into one consistent product offering for global GSM networks and provides for significant cost advantages with the savings in approvals and logistics costs.
The ruggedized design, extended temperature range, and integrated SIM card holder make the GM862-Quad the ideal platform for medium volume projects. additional features like jamming detection, integrated TCP/IP protocol stack, and Telit's Easy Scan® functionality feature extend capabilities without adding cost.
