Model

The Robustel EG5120 is a 5G-ready industrial edge computing gateway designed for mission-critical deployments, delivering global 5G/4G/3G/2G cellular backhaul and ARMv8-based edge processing. Its full-featured Debian 11 (bullseye) based operating system supports Raspberry Pi-compatible applications, while Docker enables containerized deployment in harsh environments. The gateway integrates RobustOS Pro – Robustel’s self-developed OS with enterprise-grade cybersecurity (VPN/IPsec/Smart Roaming) and SMS remote management.

Powered by a quad-core 1.6GHz Cortex-A53 CPU and a dedicated NPU (2.3 TOPS), the EG5120 accelerates machine learning inference for edge AI workloads. Combining cellular routing with embedded computing capabilities, this ruggedized platform serves as an all-in-one solution for industrial automation, smart cities, and real-time AI-driven decision-making at the network edge.
