System Description
This chapter describes the context of the CEREC Radio Device by describing the main
function and identifying the system components.
4.1
CEREC System
Mobile acquisition unit and a stationary milling unit.
The acquisition unit generates the restoration data which is to be transmitted to the
milling unit.
The acquisition unit completes this by setting up a TCP/IP connection to the milling unit.
An Ethernet infrastructure is required to facilitate this.
This can be implemented by a standard wired LAN infrastructure, Wi-Fi or the CEREC
Radio Device system as described in this document.
4.2
System Components
The identifiable components and their role in the CEREC system are listed below:

data communication to
the milling unit.
Milling unit
Receives the data and processes it
to mill a restoration.
Data receiver.
Operator
Person possessing technical
knowledge (either by experience,
instruction or education) about the
operational details of the network.
Performs all
infrastructural changes to
the network using
technical knowledge.
Dentist
User who does not possess any
technical knowledge about the
working of the network.
