LoRa Gateway


WB-3628 is the industrial wireless gateway for LoRa to RS-485, which is suitable for widespread area where requiring the long-range, low data, and non-immediateness communication.
LoRa is Low-Power and Long-Range transmission protocol and features good anti-interference performance to prevent electronic jamming.


• LoRa Wireless data link provide stable data stream.
• Wide voltage operation for Industrial applications.
• High output RF Power and high sensitivity provide more then 40KM transmission distance.
• Multi-Interface support RS-485 / RS-232.
• AUX Power output for general purpose such as plug-in sensor, or other sub system.
• Software setting function such as Frequency / ID / P2P / Group / Broadcast / Power output ….
