R5020
Industrial Dual-SIM 5G Router with 4x LAN, Serial, GNSS & PoE
The Robustel R5020 is an industrial 5G router designed for dependable site and in-vehicle connectivity across global 5G/4G/3G bands. Built on RobustOS, it supports familiar networking features with centralized fleet operations via RCMS for monitoring, configuration, and updates.
Compliant with 3GPP Release 15, the R5020 suits three common roles: in-vehicle backhaul (passenger Wi-Fi, onboard systems), broadband failover, or primary wireless broadband where fixed lines are impractical.
Vehicle deployments are supported with E-mark certification, GNSS positioning, and an ignition-sense option to protect batteries when engines are off.
In summary, the R5010 delivers cost-effective 5G backup for SD-WAN appliances, centrally managed at scale.
For branch and enterprise use, the router can use Ethernet or Wi-Fi as primary access with automatic failover to 5G/4G. Security options include IPsec, OpenVPN and DMVPN to connect sites to core networks.
The result is reliable, scalable 5G connectivity with straightforward, centralized management, the R5020 delivers high-throughput 5G with centralized fleet management to reduce rollout time and downtime across vehicles and branches.

Introduction
The R5020 is Robustel's first 5G-capable router supporting global 5G, 4G, and 3G bands. It leverages a proven high-performance CPU platform and RobustOS - a mature and stable operating system developed in-house by Robustel. The R5020 is compliant with 3GPP Release 15 and is designed for the following applications:
In-vehicle Applications: Whether for passenger Wi-Fi, CCTV monitoring, ticketing, or other onboard requirements, the R5020 provides a simple and effective solution to enhance internet speeds and future-proof existing installations. It has achieved E-Mark certification for in-vehicle use and supports GNSS positioning. A version with vehicle ignition sensing is also available to protect vehicle batteries when the engine is off.
Broadband Failover: The R5020 can be configured to use Ethernet or Wi-Fi as the primary internet connection, with automatic failover to 4G/5G in the event of an outage. This provides resilience for establishments such as retail shops and small offices at a reasonable cost,ensuring sufficient bandwidth for multiple users. It supports IPsec, DMVPN, and OpenVPN protocols for secure connections to core networks.
Primary Broadband: Cellular networks now offer unlimited 5G plans at competitive prices, delivering hundreds of Mbps of internet connectivity wirelessly. For many users, the opportunity to eliminate wired connections and utilize a wireless internet solution can be both technically and commercially advantageous.
The Robustel Cloud Manager Service (RCMS) is a unified cloud-based platform designed for real-time monitoring and centralized management of industrial IoT devices. Fully compatible with Robustel routers and gateways, RCMS delivers an interactive geospatial dashboard that enables users to visualize device locations and track critical metrics such as data usage, signal strength, and network status. To ensure seamless operations, the platform facilitates over-the-air (OTA) updates for firmware, configurations, and applications, minimizing downtime while optimizing system performance.
