LG3120e
LG3120e
Industrial Edge Computing LoRaWAN Gateway with 4G, eSIM, Wi-Fi, Serial and I/O
The LG3120e is a high-performance industrial edge LoRaWAN gateway designed for remote and distributed field deployments where traditional cabling is difficult, costly, or impractical. By merging server-grade processing power—featuring a quad-core 2.0 GHz CPU and 2 GB RAM— with the comprehensive E2C Field Suite, the LG3120e provides a native LoRaWAN ecosystem for rapid wireless networking.
Operating on RobustOS Pro (Debian 11), the LG3120e acts as a centralized intelligence hub that solves the "Last Mile" connection problem. It enables plug-and-play monitoring for outdoor and distributed assets, bridging the gap between isolated field sensors and cloud-based analytics without the need for complex cabling.
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.
Features
- Wireless Last Mile Connectivity: Built-in LoRaWAN connectivity enables rapid deployment across distributed or remote sites where cabling is costly or impractical.
- Zero-Touch Sensor Onboarding: Automatically recognizes LoRaWAN sensors with over 300 pre-built codecs, generating data points and semantic tags in seconds for true plug-and-play monitoring.
- Integrated LNS: Built-in LoRaWAN Network Server for centralized device management and real-time monitoring of wireless field assets.
- E2C Field Data Integration: Supports LoRaWAN, Modbus, OPC UA, and BACnet to normalize fielddevice data for edge processing and cloud integration.
- Visual Logic and Dashboard: Specialized Node-RED nodes and a built-in visualization engine for dragand- drop automation and local dashboards.
- Server-Grade Performance: A quad-core 2.0 GHz CPU and 2 GB RAM enable local data processing to help reduce cloud traffic and application latency.
- Industrial I/O Density: Includes 2 x RS-232/485, 2 x DI, and 2 x DO interfaces to reduce the need for external I/O modules.
