The MS48-LR is an open-source LoRaWAN To Modbus Gateway. It lets you bridge LoRa wireless network to an IP network via WiFi , Ethernet or Cellular Network (via Optional 4G module). The LoRa wireless allows users to send data and reach extremely long ranges at low data rates.

The MS48-LR is fully compatible with LoRaWAN protocol. MS48-LR includes a built-in LoRaWAN Server and IoT server, User can connect virous LoRaWAN devices to MS48-LR, and use PLC to access these devices via Modbus network.

Different countries use different LoRaWAN frequency bands. MS48-LR has these bands pre-configured. Users can also customize the frequency bands to use in their own LoRa network.

MS48-LR supports remote management. System Integrator can easy to remote monitor the gateway and maintain it.
