The Bosch Router CM-R 19 is a mobile WLAN access point designed for use in commercial vehicles, specifically buses, operating on either a 12 V or 24 V electrical system. Its primary function is to provide passengers with internet connectivity and access to audio/video content from other devices within the coach infotainment system. The device is available in two main variants: 7 620 320 032 and 7 620 320 034 (NAFTA).
Function Description:
The Router CM-R 19 acts as a central hub for wireless communication within the vehicle. It integrates mobile radio capabilities (LTE-FDD, LTE-TDD, UMTS/DC-HSPA+, WCDMA) to establish an internet connection, which is then distributed via WLAN (IEEE 802.11a/b/g/n/ac) to passenger end devices. The device supports two SIM card slots, allowing for automatic switching between cards to optimize connectivity and potentially reduce roaming costs on international routes.
Beyond internet routing, the CM-R 19 also functions as a media server. It can make media content available to end devices via WLAN by connecting USB data carriers to its front USB sockets (one of which is specifically recommended for content protected by digital rights management, DRM). This allows passengers to access stored audio and video files directly from the router.
The device features a user-friendly web-based interface, accessible via a standard internet browser (http://bosch.router), which allows for comprehensive configuration and monitoring. This interface is password-protected by default for security.
