R1520
R1520
Industrial Dual-SIM 4G/LTE Router with 5 x LAN Ports, GNSS, Serial, DI/DO, Analog Input and a Globally Certified SKU.
The Robustel R1520 is an industrial LTE router for multi-site IoT connectivity, combining five Fast-Ethernet ports (configurable 1×WAN + 4×LAN), 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. The series also includes Standard (S) and Vehicle (V, E-mark + GNSS) variants to match site requirements.
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.
