RDC2000 Radio Data Controller & Interface Unit

The RDC2000 is used both as a base end interface for MDT mobile data systems and also as a vehicle data controller when full dispatch is not required i.e. for AVL or vehicle management systems data transmission.

Base Controller

When used as a base controller the RDC2000 provides the interface between the wireless radio and the computer server running the mobile data gateway (usually Gatekeeper.) The RDC2000 is required for conventional and trunked radio systems and in some cellular based systems.

Vehicle Data Controller

The RDC2000 is used in vehicles when the mobile data system does not include a job dispatch or messaging component. In such instances the RDC2000 provides the data interface to the wireless system for such peripherals as GPS, portable data collectors (PDTs) or vehicle management systems.

When interfaced with a GPS for use in an automatic vehicle location (AVL) system the RDC2000 has all of the GPS data management capabilities of the MDT400 and WDT2000 including separate location acquisition and transmission criteria, on-board geofencing etc.

The WiPath wireless data network (WDN) structure which includes the RDC2000 is designed to minimise the number of transmissions and the amount of data transferred to keep data and wireless network costs to a minimum.
