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 Basics™ 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.
Features

Introduction
The R1520LG is Robustel’s innovative LoRaWAN gateway, specifically engineered for highvolume in-building applications. Combining cost-effectiveness with exceptional versatility, this gateway addresses a wide range of deployment scenarios, including:
- • External LoRa Network Server (LNS): Choose from multiple packet forwarders such as UDP, Basic Station, or Loriot for tailored connectivity solutions.
- • Internal LoRa Network Server (LNS): Utilize ChirpStack for comprehensive customer control over your network..
- • Enhanced Internal LNS: Our unique "E2C ChirpStack" integration, a pioneering feature, offers seamless connectivity options.
- • Direct Cloud Integration: The E2C ChirpStack software connector enables LoRa sensors to connect directly to AWS and Azure cloud environments, simplifying data management.
- • Dual Functionality: E2C ChirpStack can be paired with E2C Modbus within the R1520LG, allowing easy data aggregation from both wired and wireless sensors into the cloud.
The Robustel Cloud Manager Service (RCMS) is a unified cloud-based platform designed for real-time monitoring and centralized management of industrial IoT devices. Fully compatible with Robustel routers and gateways, RCMS delivers an interactive geospatial dashboard that enables users to visualize device locations and track critical metrics such as data usage, signal strength, and network status. To ensure seamless operations, the platform facilitates over-the-air (OTA) updates for firmware, configurations, and applications, minimizing downtime while optimizing system performance.
