LEON-G1 series modules are cost efficient solutions offering full quad-band GSM / GPRS data and voice functionality in a compact LCC (Leadless Chip Carrier) form factor. Featuring low power consumption and GSM/GPRS class 10 data transmission with voice capability, LEON-G1 series modules combine baseband, RF transceiver, power management unit, and power amplifier in a single, easy-to-integrate solution.
LEON-G1 series modules are fully qualified and certified solutions, reducing cost and enabling short time to market. These modules are ideally suited for M2M and automotive applications such as: Automatic Meter Reading (AMR), Remote Monitoring Automation and Control (RMAC), surveillance and security, eCall, road pricing, asset tracking, fleet management, anti theft systems and Point of Sales (PoS) terminals. LEON-G1 series modules support full access to u-blox GNSS positioning chips and modules via the GSM modem. GSM and GNSS can be controlled through a single serial port from any host processor. The LEON-G1 compact form factor and SMT pads allow fully automated assembly with standard pick & place and reflow soldering
equipment for cost-efficient, high-volume production.
