Robustel routers are designed specifically for M2M, as the name suggests they are manufactured to be hard wearing and operating in industrial conditions. Robustel routers are configurable so that they pick the strongest signal for multiple network M2M SIMs.
Here are 4 Robustel M2M Routers:
The Robustel M2M R1510 4G LTE router has a single SIM slot and comes with 1 Wifi and 2 Cellular antennas. The R1510 has 2 ethernet ports and 1 x DI, 1 x DO interfaces. The CPU is Atheros Max 650MHz with 16GB Flash Memory and 64GB of Ram.

Robstel M2M routers are all IoT gateways, with built-in intelligence. Routers can be sent directly to site with a M2M SIM and will auto-configure when first powered on. All models arrive with a Mobile Manager Client pre-loaded. It was developed to provide integration between our Mobile Manager portal and the Robustel router. The Mobile Manager Client auto-configures the APN and delivers real-time data to the Mobile Manager platform.
Standard SMS Reboot is available on all devices and enables remote reboot of the Robustel router and SIM via SMS.
Multi-Network SIMs connect randomly to one of the networks available to them. Enabling ‘SmartRoaming’ and defining the quality standards needed for the applications being served by the SIM results in the SIM connecting to a network that meets the standards specified. If this network then falls below one of those standards it will drop the connection and scan available networks for one that does.
Robustel M2M routers come with the RobustOS SDK. This allows developers to create software that runs directly on the router, enabling the unit to act as a fully integrated IoT Edge Gateway, removing the need for a separate PC in many applications. This offers significant cost savings, energy savings and reduces complexity when rolling out large IoT solutions.
A single SKU for global deployments. Routers with the appropriate certification that can work with a wide range of the radio frequencies that mobile operators use around the world.
Real-time data is collected directly from Robustel M2M Routers reducing the risk of out-of-bundle data charges.
A proprietary app which proactively reboots the device if offline based on parameters under the control of the use.
A 2-year warranty is provided for peace of mind.
