1 MODULE OVERVIEW
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.
