LoRa technology is one of LPWAN (Low Power Wide Area Network) communication technologies. It is an ultra-long-range wireless transmission scheme based on spread spectrum technology, providing users with a simple ability to achieve long distance, long battery life and large capacity,therefore extending the sensor network. LoRa technology has the characteristics of long distance, low power consumption, multiple borrowing points and low cost.
The alarm product has a built-in LoRaWAN wireless module, which uploads device status information and alarm information through the wireless network established by the LoRaWAN gateway cluster. It is distributed to the corresponding APP server through the MSP multi-service processing core network, and the device information can be browsed in real time through the Web or mobile terminal. Through the GIS service, each terminal device can be accurately located, which is convenient for rescue work.
