Robustel R1520 Industrial Dual-SIM Cellular VPN 4G/LTE Industrial Routers

The R1520 router from Robustel is a versatile 4G router equipped with five Ethernet ports and a range of advanced functions tailored for IoT applications. There are two core models in the R1520 family:
R1520 (S): The STANDARD version without GNSS, suitable for most light industrial and enterprise applications.
R1520 (V): The VEHICLE version, featuring E-mark certification and GNSS. This model is optimized for vehicle use but can also be utilized in various other applications.

The Linux-based operating system, RobustOS, has been developed entirely in-house, ensuring a high standard of technical support and infrequent firmware updates due to the modular nature of the OS. RobustOS includes many unique software innovations, such as:
