Overview
The Robustel R2011-A-4L Versatile IoT Router is a rugged, versatile 4G router with 5 Ethernet ports, dual SIM single standby capability, and a range of advanced functions for mission-critical IoT or M2M applications.
The R2011 runs on Robustel’s own Linux-based Operating System, RobustOS. Developed entirely in-house, this gives way to a very high standard of technical support and high reliability. Robustel offers a Software Development Kit (SDK) to allow additional customization by using C, and C++. It also provides rich Apps to meet fragmented IoT market demands such as:
RobustVPN: Highly flexible hosted VPN service so customers can easily enjoy a “fixed 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 a working state
Smart Roaming: Provides you with device-assisted intelligent network selection for roaming SIMs to improve performance and reduce risk.
RCMS: is Robustel’s free router monitoring service that is fully compatible with the R2011. It allows the customer 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 basis.
Over-the-air updates are supported for Firmware, router configuration, and Apps serving as essential ‘insurance’ if anything is not quite right during deployment.
