Products / CA-LG210 Gateway
The LoRa self-organising network system is a wireless communication system designed for networking and communication between self-organising devices, comprising a dual-channel gateway (CA-LG210) and communication nodes (CA-LCH20). It supports cloud acquisition, edge acquisition, low-power transmission, control delivery, active reporting and status upload for self-organising devices. A LoRa self-organising network is deployed once and used for life, greatly saving operating costs for customers.
