The LoRa Gateway is an ultra-long-range wireless data acquisition gateway dedicated to receiving our temperature and humidity LoRa sensor. Support GPRS (850,900,1800,1900MHz), RS485, MODBUS-RTU interface. LoRa Gateway uses high-performance 32-bit industrial processor and industrial-grade wireless module, with high reliability, stability and data security. LoRa Gateway support the local sound and light alarm, SMS alarm, GPRS alarm and other alarm methods.
Different from the previous ASK, FSK,GFSK, this gateway use a special spread spectrum modulation technology LoRa greatly improved the sensitivity of the received, up to 157db link budget so that the wireless communication distance has improved significantly. The distance can up to 5km in open area.
