Lora, one of LPWAN communication technologies, is a wireless transmission scheme based on spread spectrum technology adopted and promoted by Semtech In the United States.  This scheme changes the traditional compromise between transmission distance and power consumption, and provides users with a simple system that can achieve long distance, long battery life and large capacity, thus expanding the sensor network.  At present, lora mainly operates in the global free band, including 433, 470, 868, 915MHz and so on  

Lora module is an ultra-long distance wireless transmission scheme based on spread spectrum technology.  This scheme changes the traditional compromise between transmission distance and power consumption, and provides users with a simple system that can achieve long distance, long battery life and large capacity, thus expanding the sensor network.  Lora technology has a long distance, low power consumption, many nodes, the characteristics of low cost based on lorawan network can provide secure data transmission distance of two-way communication, and with the least amount of cover area of the city network infrastructure, lora technology in agriculture, construction, wisdom wisdom logistics and so on the many kinds of application scenarios are used widely
