An automotive router, or vehicle router uses 5G or 4G LTE to provide connectivity for whatever connected devices and applications an organization needs to use in its fleet vehicles, such as police cars, fire apparatuses, ambulances, ferries, public buses, and school buses. Maintaining connectivity anywhere on the road is crucial for enabling in-vehicle applications and real-time communication, as well as live video streaming in emergency scenarios. A dual-modem automotive or vehicle router allows SIM cards from different carriers to be active at the same time. If one signal is degraded, the automotive router switches from one carrier to another automatically and instantly. These routers can accommodate cellular and satellite, too. Dual-modem automotive routers are vital for mission-critical communications as vehicles travel across highly disparate coverage areas.
