The R1511P Embedded 4G/LTE Router is a cost-effective small footprint board. It offers Ethernet WAN, Wifi WAN and 4G WAN interfaces. These can all be independently configured in our powerful onboard Operating System – RobustOS.
The R1511P is a fully featured embedded 4G router designed for applications such as EV charging, traffic signs, vending machines, medical instrumentation, industrial instrumentation, and various other IoT applications. This embedded router addresses two key challenges that traditional routers often face: cost and size.
The R1511P is a cost-effective solution featuring a compact form factor with Ethernet WAN, Wi-Fi WAN, and 4G WAN interfaces, all of which can be independently configured within the powerful onboard operating system – RobustOS. RobustOS is Robustel’s advanced Linux-based router operating system, providing functionality that could take a software engineer many months to develop and even longer to adequately test. Key features of RobustOS include:
RobustVPN: Innovative use of Open VPN tunneling to provide a fixed IP address on the router, anywhere.
RCMS: Robustel’s Cloud management platform, essential for managing a fleet of routers, with options for OEM branding.
SMS Control: Complete control of the router via SMS for general status updates or resolving fault conditions with IP communications.
Automated failover: Easily configure the router to automatically switch from WAN/Wi-Fi to 4G with just a few clicks.
