R1500 industrial cellular IoT gateway supports
GSM/GPRS/EDGE 2G network, WCDMA and other 3G
networks, HSPA+ 3.5 G and LTE 4G network. It
provides high speed wireless network bandwidth for
device by wireless connection, and with dual-SIM
backup to ensure the stable connection of wireless

R1500 is a powerful gateway developed from
RobustOS, a Robustel self-developed and Linux-based
operating system which is designed to be used in
Robustel devices. The RobustOS includes basic
networking features and protocols providing
customers with a very good user experience.
Meanwhile, Robustel offers a Software Development
Kit (SDK) for partners and customers to allow
additional customization by using C, Python or Java. It
also provides rich Apps to meet fragmented IoTmarket demands.
