Robustel R1520 Dual-SIM Cellular VPN Router
The R1520 router from Robustel is a versatile 4G router with 5 x Ethernet ports, GPS and E-mark certification for in-vehicle use.
Other hardware features include optically isolated digital inputs and outputs as well as a 10-bit analogue input capable of interfacing directly with sensors in the range of 0 to 24Vdc or 0 to 20mA.
R1520 also has a 2-wire RS485 interface for connection to legacy instruments with full support for Modbus. The RS232 port features RTS/CTS lines so the product can accommodate applications that require hardware handshaking.
Despite being cost-effective, the R1520 is a powerful router with high packet-forwarding capability way beyond the typical requirements of LTE CAT4 networks. The Linux based Operating System, RobustOS, has been developed entirely in-house which leads to a very high standard of technical support and infrequent firmware updates due to modular nature of the OS. Many unique software innovations are built on top of RobustOS, these include:
RobustVPN highly flexible hosted VPN service so customers can easily enjoy a œfixed IP router
Data-Guard invaluable failsafe in case of a system failure and runaway data usage
Smart Reboot SMS tool to push roaming SIMs from a non-working to working state
Sniffer run a Wireshark trace directly on the router for invaluable diagnostic information. Customers can also easily write their own applications using the extensive SDK supplied free of charge.
RCMS is Robustel free router monitoring service that is fully compatible with the R1520. It allows customers to see a location overview of their routers quickly and simply on a map. Features such as data usage, signal strength, current network and much more can then be viewed on a per router. Over-the-air updates are supported for Firmware, router configuration and Apps serving as essential ˜insurance ™ if anything was not quite right during deployment.

A cellular router is a specialised networking device that uses cellular networks (3G, 4G, 5G) to provide internet connectivity in remote or challenging environments where traditional wired connections are impractical. Unlike regular routers, cellular routers are designed to operate reliably in harsh industrial settings, ensuring continuous, secure data transmission. They are essential for mission-critical applications that demand robust, uninterrupted communication. FB Peripherals is a trusted supplier of rugged cellular routers, providing durable solutions tailored for industrial and outdoor use. For more information on these devices, visit FB Peripherals’ rugged routers.
Yes, most cellular routers support external antennas to enhance signal strength and reliability, especially in challenging environments. External antennas are crucial for improving connectivity in remote or industrial locations where signal reception may be weak or obstructed. Rugged cellular routers often feature ports for attaching a variety of antenna types, including omnidirectional and directional antennas, to optimise performance. For mission-critical applications, choosing a reliable source like FB Peripherals ensures access to quality rugged routers and compatible cellular router antennas designed for harsh conditions.
