Robustel R2011

Industrial Dual-SIM 4G/LTE Router with 5 x LAN Ports


The Robustel R2011 is an industrial 4G/LTE router designed for dependable site connectivity and straightforward fleet operations.

Five 10/100 Ethernet ports (4×LAN + 1×WAN or 5×LAN) allow simple on-site segmentation without an external switch. Dual-SIM redundancy and Link Manager coordinate failover across cellular, Ethernet, or Wi-Fi backhaul to maintain service continuity. Security is comprehensive with IPsec, OpenVPN, GRE, and WireGuard, managed via Web/CLI/SMS and at scale through RCMS.

RobustOS (Linux-based) provides a C/C++ SDK and App Centre for application-specific extensions, while RobustVPN enables fixed-IP remote access when needed.

An optional PoE-PD WAN port supports flexible installation. The metal IP30 enclosure, 9–36 V DC input, and −35 to +75 °C operating range suit control cabinets, kiosks, and remote panels. The result is reliable connectivity, flexible networking, and secure lifecycle management in a compact, cost-effective platform.
