The network uses 5.8 GHz WiFi Mesh as the backbone network and CN470 frequency band LoRaWan as the narrowband transmission network. This wireless transmission network for field agriculture can meet the narrowband data transmission needs of local climate, soil, and crops as sensing objects, as well as support the broadband data transmission needs of devices such as visual perception.
