The Robustel LG5120 is an industrial-grade edge computing gateway engineered specifically for building automation and facility management. Where most IoT gateways aggregate data and forward it upstream, the LG5120 is designed to act on it locally — running automation logic, triggering controls, and generating dashboards at the edge while syncing with cloud platforms for centralised reporting and fleet management.
The hardware is built around the protocols buildings actually use. A dedicated KNX TP port and KNXnetIP over Ethernet connect directly to lighting systems, HVAC controllers, and room management units without a protocol converter. Two isolated RS-485 ports handle Modbus RTU and BACnet MS/TP field devices. M-Bus manages heat, water, and energy meter networks. A dedicated P1/DSMR port (up to 115,200 bps) connects directly to high-speed Dutch smart meters for real-time consumption data — particularly relevant for EU868 deployments in the Netherlands and Belgium. Two software-configurable analog inputs (0–24V or 4–20mA) accommodate sensors that don’t use a digital bus. An onboard Semtech SX1302 LoRaWAN chipset covers wireless sensors — temperature, humidity, occupancy, CO₂ — across 8 simultaneous channels on EU868, AU915, or AS923 frequency plans.
Processing runs on a Quad-core ARM Cortex-A53 at 1.6 GHz with an integrated NPU rated at 2.3 TOPS, 8 GB DDR4, and 64 GB eMMC — with 7 GB of RAM and 60 GB of flash available to the SDK. The E2C Facility Suite provides the software framework: unified data acquisition across KNX, BACnet, Modbus, and OPC-UA; Node-RED orchestration with automated scene management for trigger-based control; BACnet IP and OPC-UA data forwarding to external BMS or SCADA systems; and a drag-and-drop HMI/SCADA dashboard builder with real-time multi-channel alarms.
The R1320LGe is a compact industrial LoRaWAN gateway built for reliable packet forwarding at scale. It collects upstream data from LoRaWAN end-nodes across EU868, AU915, US915, and AS923 frequency plans and forwards it via standard LoRaWAN packet forwarding protocols to any compatible LNS — ChirpStack, The Things Network, LORIOT, Actility, and others running on-premises or in the cloud.
Three backhaul options adapt to the infrastructure available at each site. 4G LTE Cat-4 cellular provides connectivity where wired infrastructure isn’t accessible. Fast Ethernet connects directly to an existing LAN. PoE-PD (802.3at) on ETH0 allows the gateway to draw power from a PoE-capable switch, removing the need for a separate power run to the installation point a practical advantage in comms rooms, distribution cabinets, and riser spaces where power outlets are limited.
Dual SIM support one MFF2 eSIM alongside a physical Mini SIM (2FF) slot — simplifies cellular provisioning across multi-site deployments, with the option to switch or reassign carriers remotely without physical access to the device.

The Robustel R5020Le is an industrial 5G router that brings eSIM/eUICC flexibility to high-performance edge deployments. Built on the R5020-Lite platform, it uses a hybrid SIM design—one physical SIM plus an embedded MFF2 eSIM compliant with GSMA SGP.22—so organisations can standardise global rollouts while reducing SIM logistics and long-term operational overhead.
The embedded eSIM enables over-the-air profile download, activation, and switching, making it easier to adapt operator choices as coverage, roaming needs, or pricing change across regions. It also adds practical safeguards for scaled deployments, including secure profile control, automatic rollback to a working profile if provisioning fails, and profile rotation to avoid locking fleets into long-term roaming arrangements or maintenance-heavy SIM swaps.
On the connectivity and management side, the R5020Le supports global 5G/4G/3G bands and 3GPP Release 16, runs RobustOS, and can be managed centrally through Robustel Cloud Manager Service (RCMS) for monitoring, configuration, firmware upgrades, and eSIM profile operations. With flexible WAN design—Ethernet or Wi-Fi as primary with cellular failover, or 5G as the main link—and multiple mounting options to improve signal placement, it’s well suited to distributed sites where performance and uptime matter as much as provisioning efficiency.
The Robustel R5030 is an industrial 5G router built for high-performance connectivity in vehicles and at the edge.
It supports global 5G/4G/3G bands and 3GPP Release 15/16, pairing cellular backhaul with dual-band Wi-Fi 6 in AP or Client mode for dense user environments.
Captive portal and dedicated GNSS suit fleet and passenger Wi-Fi deployments, while Ethernet or Wi-Fi can serve as primary access with automatic failover to 5G/4G for continuity.
Security and interoperability are enterprise-grade with IPsec, DMVPN and more, and operations scale through RCMS for centralized monitoring, configuration, and updates. A compact metal enclosure with DIN-rail or wall mounting simplifies installation in cabinets and vehicles.
The result is fast, resilient 5G with modern Wi-Fi that’s straightforward to deploy and manage across transit fleets, venues, and branch sites.
