The MS48-LR is an open-source LoRaWAN To Modbus Gateway. It lets you bridge the 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 the LoRaWAN protocol. MS48-LR includes a built-in LoRaWAN Server and IoT server, The User can connect various LoRaWAN devices to MS48-LR, and use PLC to access these devices via the 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 easily remotely monitor the gateway and maintain it.
