M120N LTE Industrial/In-Vehicle Multi-Carrier Router

The M120N Advanced Industrial/In-Vehicle LTE Router is a high-performance all-in-one fixed/mobile wireless communications platform with advanced software enabling high availability, and reliable and secure connectivity for mission-critical applications. The compact, rugged design integrates dual SIMs, a four-port Gigabit Switch, Wi-Fi Access Point, an embedded multi-GNSS receiver for GPS or GLONASS, and ignition sensing for in-vehicle applications. The M120N is specifically designed to support a wide range of applications in the Smart Bus and M2M segments.

The Billion M120N enables high availability, reliable and secure wireless connectivity for mission-critical applications. The Billion M120N can be operated at a wide-range temperature -40°C ~ 60°C, with a compact enclosure. The Billion M120N can also support VPN functions and has RS-232 / RS-485  port to support serial communications protocols, such as Modbus as well.

As for in-vehicle applications, the Billion M120N support LTE with dual SIM. The Billion M120N can enable live video streaming for vehicle surveillance purposes. The Billion M120N support a Wi-Fi 802.11n Access Point and Hotspot Captive Portal functions, allowing passengers to enjoy cellular services and advertising push options. In addition, with flexible power input DC 10V~56V and ignition sensing, the M120N is suitable for any size of vehicle that can be automatically turned off to avoid battery draining.
