The Robustel EG5101 is a new industrial edge computing gateway, supporting 4G Cat 1 network for cellular backhaul, with a fully-fledged Debian 11(bullseye) based operating system able to support thousands of existing or new ARMv7 (Raspberry Pi compatible) based applications.
The Robustel EG5101 is an industrial edge computing gateway delivering LTE Cat 1 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.
