Robustel R1520 Global
Globally certified industrial Dual-SIM 4G/LTE router with 5ร LAN, GNSS, serial, DI/DO, and analog input for versatile field deployments.
The Robustel R1520 Global is an industrial LTE router for multi-site IoT connectivity, combining five Fast-Ethernet ports (configurable 1รWAN + 4รLAN), dual-SIM resilience, and Wi-Fi/Ethernet WAN options in a compact form factor. Security and remote operations are built in: IPsec, OpenVPN, GRE, WireGuard and DMVPN, plus RCMS for fleet monitoring, configuration and updates, and RobustVPN for fixed-IP access on any SIM.
For projects that span regions, the R1520 Global SKU consolidates wide LTE band coverage and a deep set of certifications (e.g., FCC/PTCRB, CE, RCM, ICASA, TDRA and more) to simplify procurement and deployment across markets.
Optional PoE-PD on ETH0 simplifies installation; DI/DO, analog input, and RS-232/RS-485 support common integration needs. The result: reliable, secure connectivity with a single platform that scales from local pilots to global rollouts.

Example R1520 Global Use Cases
Heavy Equipment Fleets
Globally certified LTE router for heavy equipment fleets operating across regions. Delivers secure backhaul for telematics, diagnostics, and operator systems; dual-SIM failover helps maintain uptime as machines move between sites and countries; RCMS centralizes configuration, monitoring, and firmware updates across the fleet.
OEM Global Machinery
Globally certified LTE router for OEMs shipping industrial machinery worldwide without redesigning connectivity for each destination. Provides secure cellular WAN that works across regions, reducing reliance on local fixed networks and site-specific IT; dual-SIM resilience helps maintain uptime when carrier performance varies.
Global Retail & Branch Sites
Globally certified LTE router for global retail, branches, and distributed locations. Supports consistent deployment across countries with reliable primary or backup WAN; keeps POS and store operations online with dual-SIM resilience; enables standard templates and faster rollouts via RCMS, reducing local variation and support effort.
