VR2000 applications
Applications for VR2000 include operation as a stand-alone Mobile Data Terminal (MDT) for job despatch/remote working systems through to highly integrated systems implementing mobile data, vehicle tracking, telecommand/telecontrol multiple communications bearers and in-vehicle IP networking.
The range of applications that the VR2000 can be configured, programmed or adapted to is almost limitless...
The Vehicle Area Network (VAN)
The diagram above (click for larger version) shows one such application where VR2000 operates across two IP enabled radio networks and operates as both a mobile data terminal in its own right and as an IP packet router for other devices in the vehicle.
Operation as an in-vehicle IP router extends the corporate Local Area Network (LAN) and Wide Area Network (WAN) to the vehicle enabling the Vehicle Area Network (VAN).
Multiple radio bearer support
The VR2000's flexible IP networking protocol stack allows it to support multiple IP network connections and route data over the most effective (most reliable, lowest host, highest bandwidth) based on the nature of the traffic. One example is where both IP packet data over TETRA and IP packet data over GSM (GPRS) are installed in a vehicle - for example an Ambulance.
Here combining the benefits of both network types allows the optimum mixture of reliability, transmission speed and cost to be leveraged - devices attached to the Vehicle Area Network (VAN) do not need to now which path their data is routed over - it is seemlessly delivered over the most appropriate network connection available at the time.
Integrated GPS receiver
The integrated GPS receiver in VR2000 allows the unit to implement positioning and timing applications which include Automatic Vehicle Location (AVL) and data logging ("Black box fliught recorder&qout;) and provide timing and location services to other equipment on the Vehicle Area Network (VAN).
The "black box" recorder functionality allows recording vehicle journey, driving speeds and status information gathered from digital inputs or externally connected sensors - for example temprature or fuel levels.
