Industrial 4G VPN Routers

Industrial 4G VPN Routers

Industrial 4G VPN routers provide reliable and versatile connectivity for widespread M2M and IoT deployments across the globe. Featuring 4G LTE modules, dual-SIM failover, and rich industrial interfaces, these devices run on the secure, Linux-based RobustOS to guarantee continuous uptime and enterprise-grade VPN security. The entire global fleet is centrally monitored and managed through a unified cloud platform, simplifying large-scale international deployments.

The Workhorse of IIoT: Reliable & Secure 4G VPN Connectivity

In the vast landscape of the Industrial Internet of Things (IIoT) and Machine-to-Machine (M2M) applications, many critical assets are deployed in remote, mobile, or temporary environments where wired networks (like fiber or DSL) are unavailable or impractical. 4G LTE cellular provides the most ubiquitous, reliable, and cost-effective connectivity solution available today.

But getting "connected" is not enough. When you need to transport sensitive business data from PLCs, SCADA systems, POS terminals, or remote sensors over the public internet, security becomes the number one priority.

This is where an Industrial 4G VPN Router demonstrates its core value. It is a device purpose-built for 24/7 reliability in harsh industrial environments, whose primary mission is to create a high-strength, encrypted, and secure tunnel over the public 4G network to protect your critical data from threats.

Why Choose Robustel Industrial 4G Routers?

Robustel is a global leader in industrial 4G connectivity. Our routers (like the R1520 and R2120 series) are engineered from the ground up to solve the unique challenges of the industrial world.

• Powerful Enterprise-Grade VPN Our routers are comprehensive security gateways. They feature a full suite of embedded VPN protocols (including IPsec, OpenVPN, GRE, L2TP, and more). This allows you to easily build secure tunnels from your remote sites back to your corporate headquarters, data center, or major cloud platforms (AWS, Azure), ensuring seamless interoperability with your existing IT infrastructure.

• "Always-On" Connectivity: Dual-SIM Failover In industrial applications, a lost connection can be catastrophic. Our routers come standard with Dual-SIM slots for automatic carrier failover. If the primary carrier's network fails, the device instantly and automatically switches to the backup carrier, ensuring your remote assets are always online.

• Rugged Hardware Built for Harsh Environments "Industrial-grade" is not a marketing term for us. It means a rugged metal enclosure, stable operation in extreme temperatures from -40°C to +75°C, DIN-rail mounting, and a wide-range 9-60V DC power input. Our devices are built to withstand the vibration, power surges, and harsh electromagnetic (EMC) conditions of the factory floor.

• Zero-Touch O&M with the RCMS Platform Managing hundreds or thousands of 4G routers spread across the country—or the globe—is a massive challenge. Our RCMS (Robustel Cloud Manager Service) platform allows your team to centrally configure, monitor, update firmware, and bulk-deploy VPN profiles to all devices from a single point. This enables "zero-touch" operations and maintenance (O&M), dramatically reducing the cost of field service.

From ATM/POS retail deployments and smart city infrastructure (like charging piles and cameras) to utility data backhaul (water, electric, gas), Robustel Industrial 4G VPN Routers are the globally-proven, trusted solution for industrial M2M connectivity.
