EG5120
Industrial edge computing gateway with Dual-SIM 5G or 4G LTE, Serial, GNSS, DI/DO, Bluetooth and a Debian-based OS
The Robustel EG5120 is a 5G-ready industrial edge gateway that combines secure cellular backhaul with on-device processing for real-time decisions at the edge. Built on RobustOS Pro (Debian 11), it supports Docker containers and Debian packages so you can deploy protocol bridges, data buffering, and ML workloads alongside your equipment. A quad-core 1.6 GHz Cortex-A53 with 16 GB eMMC and a 2.3 TOPS NPU accelerates inference for use cases like vision or anomaly detection.
Connectivity options include dual-SIM 5G/4G/3G/2G and Ethernet WAN with link backup; security covers IPsec, OpenVPN, GRE, L2TP, PPTP, and DMVPN. Integration is straightforward via two software-configurable RS-232/RS-485 ports, 2×DI/2×DO, native Modbus TCP/RTU, and MQTT-to-cloud bridging, with optional 802.11ac Wi-Fi and Bluetooth 5.2. Fleet operations scale through RCMS for monitoring, configuration, and updates.
The result is a rugged, open platform for reliable connectivity and high-performance edge processing in industrial and smart-city deployments.

Introduction
The Robustel EG5101 is an industrial edge computing gateway delivering LTE Cat 1 bis cellular backhaul and ARMv7-based processing. Powered by an NXP i.MX 6ULL processor (792MHz), it combines cellular routing and embedded computing in a single platform. The Debian 11 (bullseye) based operating system supports Raspberry Pi-compatible applications, while Docker enables containerized deployment for resource-efficient edge workloads.
Integrated with RobustOS Pro - Robustel’s hardened OS - the EG5101 provides enterprise-grade security (VPN/IPsec, smart roaming) and SMS-based remote management. Designed for cost-sensitive IoT deployments, it serves as a converged cellular router and embedded edge compute node for smart metering, asset tracking, and distributed monitoring in harsh industrial environments.
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.
