GL865 V3_1


Product Description

The GL865 V3.1 is the new Telit GSM/GPRS product series recommended for new designs for deployment in those regions where there is still a long way to go before 2G sunset and for those “lite” IoT applications for which there is no point in moving out from cost-optimized 2G modules to oversized and more expensive 3G/4G modules. These new modules are available both in dual-band and quad-band variants for global coverage. The GL865 V3.1 modules maintain full hardware and software compatibility with the previous GL865 V3, thereby providing a direct replacement path. Simple drop-in migration and technology upgrade path to 3G high-speed performance is also available with pin-to-pin compatible HSPA companion module UL865.

The product is highly recommended for new designs requiring GSM|GPRS coverage and 3G scalability in a compact and robust QFN package delivering easy integration and reduced impact on final application costs.


Premium FOTA Management - Easy Firmware update Over-The-Air by transmitting only a small delta file. Limited operator coverage in North America due to 2G footprint reduction policies.
