Product application
The communication between gateway and server adopts 2G / 4G signal, which can be used as long as there is mobile phone base station signal coverage. Lora signal is used for communication between gateway and terminal. In order to ensure low-power operation of nodes, gateway and node adopt star network communication mode: gateway sends data to node to wake up target node through address code, and other nodes do not wake up; data returned by node to gateway is transparent and does not wake up other nodes, and nodes do not communicate with each other, as shown in the following figure:
