August 20, 2025
Robustel’s EG5120 Industrial Edge Computing Gateway Provides Enhanced Cybersecurity, Advanced GUI & a Myriad of Software Features
Robustel’s EG5120 is a new generation of industrial edge computing gateway, which supports global 5G/4G/3G/2G networks for cellular backhaul, with a fully-fledged Debian 11(bullseye) based operating system able to support thousands of existing or new ARMv8 (Raspberry Pi compatible) based applications. EG5120 supports Docker for easy deployment of applications and benefits from ‘RobustOS Pro’ – Robustel’s latest router OS with enhanced cybersecurity, advanced GUI, and a myriad of software features including VPNs, Smart Roaming, SMS remote control, and more.
With a quad-core 1.6 GHz Cortex A53 CPU and an integrated NPU of 2.3 TOPS that greatly accelerate machine learning inference, EG5120 will take the computing power to the next level, best for edge computing and edge AI applications, can also be used as a combination of cellular router + embedded PC in all the industrial filed.

RCMS is Robustel’s free router monitoring service that is fully compatible with the EG5120. It allows customers to see a location overview of their routers quickly and simply on a map plus features such as data usage, signal strength, current network and much more can then be viewed on a per router/gateway basis. Over-the-air updates are supported for Firmware, router configuration, and Apps serving as essential “insurance” if anything is not quite right during deployment.
