Robustel R2110
Industrial Dual-SIM 4G/LTE Router with 4 x Gigabit LAN Ports
The Robustel R2110-4L is an industrial LTE Cat-4 router designed for resilient site connectivity and secure fleet operations. It provides four gigabit Ethernet ports configurable as 1×WAN + 3×LAN, with dual-SIM and link backup across cellular/Ethernet/Wi-Fi to maintain service continuity; cold/warm backup and load balancing further optimise uptime and bandwidth.
Security is comprehensive with IPsec, OpenVPN, GRE and WireGuard, managed via Web/CLI/SNMP and at scale through RCMS. PoE-PD (optional) on ETH0 simplifies installation near antennas or panels.
Integration is straightforward: dual-band 802.11ac Wi-Fi, RS-232/RS-485, DI/DO, plus USB and micro-SD for field workflows. Built on RobustOS with a C/C++ SDK and App Centre, the R2110-4L lets teams tailor networking without changing upstream applications.
An IP30 metal enclosure, 9–36 V DC input, and desktop/wall/DIN-rail mounting suit control cabinets, remote sites and in vehicle applications.
