Robustel LG3120e LoRaWAN Edge Gateway Ireland

Robustel LG3120e LoRaWAN Edge Gateway for Ireland

The Robustel LG3120e is a high-performance industrial LoRaWAN gateway built for sites where connectivity and local intelligence need to arrive together. As the official Irish distributor for Robustel, TITAN IoT supplies the LG3120e to engineers, integrators and IoT system providers across Ireland who need a powerful, secure LoRa gateway with edge processing and a built-in LoRaWAN Network Server. Running on RobustOS Pro (Debian 11) on a Quad-core ARM Cortex-A53 at 2.0 GHz with 2 GB DDR4 RAM, it processes, filters and acts on field data locally, reducing cloud dependency and latency.

IRISH APPLICATIONS

The LG3120e suits Irish deployments where LoRaWAN sensor coverage and edge processing both matter:

• Smart farming and agriculture — soil moisture, weather stations, irrigation control, livestock monitoring across Irish farms
• Remote asset monitoring — pump stations, tank farms, pressure regulators in utilities and water infrastructure
• Industrial facilities and plant — IAQ, vibration, temperature and energy sub-metering alongside Modbus PLCs and BACnet HMIs
• Construction site connectivity — environmental and asset tracking on Irish construction projects
• Projects where cellular backhaul is needed on Vodafone, Three and Eir

BUILT-IN LoRaWAN NETWORK SERVER

A native LoRaWAN Network Server handles LoRaWAN V1.0.4 Class A, B and C device management on-device across EU868 for Ireland (also AU915, US915, AS923). Pre-installed device profiles and codecs for major LoRa sensor families enable zero-configuration onboarding — attach a supported sensor and it begins reporting without manual decoder setup. Also supports external LNS via UDP, LoRa Basics™ Station, LORIOT and internal ChirpStack.

E2C FIELD SUITE — EDGE INTEGRATION

The E2C Field Suite unifies LoRaWAN, Modbus, OPC-UA and BACnet at the edge. Node-RED orchestration can trigger DO outputs or SMS alerts on threshold breaches independently of cloud availability — useful for remote or critical sites.

FREE RCMS CLOUD MANAGEMENT

The LG3120e is RCMS ready, giving Irish customers free centralised cloud-based monitoring, geospatial dashboard, OTA firmware delivery and RobustVPN for secure remote access without site visits.

ROBUSTOS PRO — DEBIAN 11 LINUX

The LG3120e runs RobustOS Pro on Debian 11 Bullseye with a multi-language SDK (C, C++, Python, Java, Node.js). 1.5 GB of RAM and 6 GB of flash are available for custom applications.

SECURE BY DESIGN

TPM 2.0 provides hardware-level key storage and attestation. An onboard RTC retains timekeeping for up to 5 days after power loss — useful for remote sites where power interruptions are a known operational condition.

RECOMMENDED ANTENNAS

For better performance and easier project specification, pair the LG3120e with:

• Poynting PUCK-2 — cellular antenna for panel or cabinet installations
• Poynting XPOL-2 — cellular antenna for challenging signal environments
• A dedicated 868 MHz LoRa antenna for the EU868 LoRa interface
