Industrial LTE Router R1511e with Integrated eSIM, WiFi and RS232
The Robustel R1511e is a compact industrial router with support for global LTE frequencies, designed for reliable connectivity of both Ethernet and serial devices.
Advanced eSIM Management
The Robustel R1511e fully utilises an integrated eSIM (MFF2) compliant with the GSMA SGP.22 standard. This technology enables remote download, activation, and switching of operator profiles over the air, optimising network coverage and costs without the need for physical SIM card replacement or on-site service visits.
Flexible Interfaces and Serial Integration
The LTE router is equipped with two Ethernet ports (configurable as LAN/WAN or dual LAN) and an RS232 serial interface for direct connection to PLCs, meters, and legacy control units. The built-in Modbus gateway (RTU to TCP) and transparent TCP/UDP modes simplify integration of serial technologies into IP networks without requiring changes to supervisory software.
The WiFi interface (AP/Client), together with the automatic failover function, supports flexible backhaul network designs across 4G/3G/2G, Ethernet, or wireless connections.
Compact Design and Use Cases
With dimensions of just 91.5 × 91.5 × 31.5 mm, the R1511e is one of the smallest industrial routers on the market. It is an excellent choice for installations where space is limited, such as vending machines or compact control cabinets.
The Robustel R1511e is an ideal solution for IoT projects requiring rapid deployment, high security, and maximum flexibility when selecting connectivity providers worldwide.
- For legacy systems, it provides mobile connectivity to existing serial devices without costly hardware replacement. eSIM support enables remote service activation, while the RCMS platform ensures clear centralized management and monitoring of the entire network.
- For industrial telemetry, it enables efficient data collection from sensors and controllers with secure transmission over mobile networks. Remote configuration capabilities significantly reduce installation and maintenance costs in the field.
- For environmental and energy monitoring, it is an ideal solution for continuous data transmission in utility and ecological projects. eSIM technology removes the need for physical SIM handling, simplifying project scaling and enabling fully remote connectivity management.
Remote Management with Zero Touch Technology
Using RCMS (Robustel Cloud Manager Service) and Zero Touch eSIM Provisioning technologies, eSIM profiles can be remotely assigned and activated at scale. This system overcomes the limitations of the standard SGP.22 protocol and enables true mass deployment without manual configuration.
Advanced VPN Security
The router offers a comprehensive range of VPN protocols, including IPsec, OpenVPN, GRE, and WireGuard, ensuring secure integration with corporate infrastructure.
RobustOS Operating System
The R1511e runs on modular RobustOS, a Linux-based operating system designed specifically for industrial IoT needs. It supports installation of additional applications via the SDK, allowing router functionality to be tailored to specific project requirements without changing the device firmware.
