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.
