R1520LG is Robustel’s new and unique indoor LoRaWAN gateway, optimized for high volume in-building applications.The product has been designed to be very cost-effective and extremely versatile – providing a solution for all deployment scenarios including:

  1. External LNS with a choice of packet forwarders – UDP / Basic Station / Loriot
  2. Internal LNS (Chirpstack) with full customer control
  3. Internal LNS (Chirpstack) + “E2C Chirpstack” – NEW & UNIQUE!
  4. Robustel’s “E2C Chirpstack” software connector allows LoRa sensors to be connected directly into AWS & Azure cloud environments.
  5. E2C Chirpstack can be used alongside E2C Modbus in the R1520LG to get data from wired and wireless sensors easily into the cloud.

Watch this video to see how R1520LG can act as a complete hosting environment (Debian Linux) – for IoT applications – especially those connecting to LoRa and Modbus sensors.

How to host ALL of your IoT project on an R1520LG

 

RCMS is Robustel’s free router monitoring service that is fully compatible with the R1520LG. It allows customer to see a location overview of their routers quickly and simply on a map. Features such as data usage, signal strength, current network and much more can then be viewed on a per router basis. Over-the-air updates are supported for Firmware, router configuration and Apps serving as essential “insurance” if anything was not quite right during deployment. You can try Robustel’s free router management platform by signing up here: https://rcms-cloud.robustel.net
