Industrial LoRaWAN Edge Gateway
Model: R1520LG
Product Overview
The Robustel R1520LG is an industrial LoRaWAN gateway that combines a high-performance 8-channel LoRaWAN interface with the power of an open edge computing platform. It is designed to function as either a standalone, all-in-one LoRaWAN solution or as a simple gateway for large-scale networks.
● High-Performance LoRaWAN & Backhaul
● Features a modern Semtech SX1302 LoRaWAN chipset (8-channel) with multiple backhaul options, including 4G LTE (Dual SIM), Wi-Fi, and Ethernet with PoE PD support.All-in-One LNS & Open Edge Computing
● Functions as a self-contained, private LoRaWAN network with its built-in ChirpStack LoRaWAN Network Server, or operates in Packet Forwarder mode for larger networks. This powerful edge platform also supports Docker, Node-RED, MQTT, Modbus, and BACnet for developing custom applications.Secure & Reliable Industrial OS (RobustOS Pro)
● Powered by RobustOS Pro, our secure industrial OS built on Debian 11. Its development is certified to IEC 62443-4-1 and validated by penetration testers, while system resilience is ensured by Automatic System Failback. The platform is backed by an industry-leading 10-year Linux LTS.Simplified Cloud Management
Integrates fully with the RCMS cloud platform for fleet-wide monitoring, OTA updates of both the OS and applications running in containers, and secure remote access to end devices like PLCs, dramatically reducing operational costs.
