Industrial LoRaWAN Edge Gateway Robustel LG3120e
The Robustel LG3120e represents a new generation of high-performance industrial gateways, combining an advanced LoRaWAN wireless interface, stable 4G/LTE Cat 4 cellular connectivity, modern eSIM technology, and server-grade computing power. The device serves as a central intelligent hub for remote sites and demanding industries. It is an ideal solution for locations where the installation of traditional cabling is technically complicated or economically unviable.
Thanks to the integrated E2C Field Suite software package and the built-in ChirpStack Network Server, the LG3120e gateway can unify wireless data from IoT sensors with wired industrial protocols (Modbus, OPC-UA, BACnet) directly at the network edge and securely transmit them to the cloud or SCADA systems.
Typical Use Cases
- Smart Agriculture: Soil sensors, weather stations, and other monitoring nodes in vast areas often face the infeasibility of cabling and the unreliability of the cloud. The LG3120e gateway solves this problem with an integrated LNS for local data collection and powerful hardware that ensures data pre-processing and secure storage in memory even during connectivity outages.
- Industrial Automation and OEM: The LG3120e industrial gateway and the E2C Field Suite software bundle connect wireless LoRa sensors with wired PLC systems (Modbus/BACnet) into a single unified data stream for SCADA or the cloud. Thanks to pre-installed sensor profiles, integration is immediate, while the built-in dashboard allows monitoring of key metrics locally at the network edge even without transmitting data to the cloud.
- Remote Infrastructure Monitoring: Secure connection of isolated locations (water management, agriculture, weather stations) utilizing redundant LTE backup and smart roaming.
Data Unification with E2C Field Suite
A native software suite for easy data integration without the need for programming (zero-code). It effectively bridges the world of wireless LoRaWAN networks with Modbus RTU/TCP, OPC-UA, and BACnet industrial protocols.
High Hardware Performance and RobustOS Pro OS
The quad-core ARM Cortex-A53 processor (2.0 GHz) is complemented by 2 GB of RAM and 8 GB of eMMC flash storage. The operating system, based on the stable Debian 11 (Bullseye) distribution, allows running local edge applications.
Global Connectivity with eSIM Support (SGP.22)
Alongside a standard Mini SIM slot, it offers an integrated eSIM (MFF2) compliant with the GSMA SGP.22 standard. This enables remote downloading of operator profiles Over-the-Air.
Top-Tier Wireless and Wired Backup
The device features Wi-Fi 6 (802.11ax), two Ethernet ports, and support for Smart Roaming technology, which continuously evaluates the actual quality of the internet connection (not just signal strength) for maximum data continuity.
RCMS Remote Management
Full integration with the Robustel Cloud Manager Service (RCMS) cloud platform enables real-time monitoring of the entire device fleet, bulk firmware updates, and remote troubleshooting without the need for a technician dispatch.
