This LPWAN Module GL6509 is a general purpose SMT module for sensor integration. Sensor
vendors can speed up their LPWAN integration by embedding this module in their designs. This
module will take care of the LPWAN communication with our LPWAN AP and cloud services.
There are different integration options: the sensor design can integrate this SMT module via AT
command set treating this module as a LPWAN modem; the interface can be via Modbus interface;
and the entire sensor be controlled by the MCU of the module through GPIO or I²C or UART.
This GL6509 Module complies with the LoRaWAN Class A protocol specifications. It integrates RF,
a Low-Power Long Range transceiver and an application MCU. Together with the integration to
our LPWAN gateway and back-end cloud service, making this a total IOT network solution.

The GL6509 module is based on LoRa technology to provide low power long range
communication using spread spectrum. This provides very high receive sensitivity enabling
communication with high interference immunity.
Using LoRa modulation, depending on the spreading factor (SF), GL6509 can achieve system
receiver sensitivity of -137.5 dBm.
