Robustel R1520LG
LoRaWAN gateway with 4G/LTE, Wi-Fi and integrated LNS.
The Robustel R1520LG is an industrial LoRaWAN gateway engineered for building-scale and plant deployments. It combines 4G/LTE cellular and Wi-Fi backhaul with PoE-PD power, letting you place the gateway where RF performance is best.
Deploy with your preferred architecture: connect to external LNS platforms via UDP, LoRa Basicsโข Station, or LORIOT. Alternatively run the embedded ChirpStack server for full on-device control and send data straight to AWS or Azure using the Edge2Cloud ChirpStack connector with built-in buffering.
Two Ethernet ports (WAN/LAN), dual-SIM, and RS-232/RS-485 simplify integration with existing controllers and BMS/SCADA networks.
Based on Debian Linux, the R1520LG can also host applications and when paired with Edge2Cloud Modbus, aggregate wired and LoRa sensors at the edge. Fleet operations are streamlined through RCMS Device Management and RobustVPN allows secure remote access from anywhere in the world.

R1520LG Product Overview Video
Example R1520LG Use Cases
Smart Building Enablement
Monitor IAQ, temperature, occupancy and sub-metering to cut HVAC costs. PoE-PD enables optimal placement; use integrated ChirpStack or connect to your preferred LNS.
Utility Submetering
Collect and aggregate LoRa data from water, gas and electricity meters. LTE/Wi-Fi backhaul with local buffering ensures reliable readings and straightforward BMS/SCADA or cloud integration.
Cold-Chain Monitoring
Monitor temperature and humidity across fridges, freezers and vehicles. Get deviation alerts, buffer data during outages, and forward records to compliance systems via your choice of LNS.
