System description

This section explains the context of the CEREC Radio Device by 

describing the main function and identifying the system components.

5.1

CEREC system

The CEREC system consists of a mobile acquisition unit and a stationary 

milling unit.
The acquisition unit generates the restoration data which is transmitted to 

the milling unit.
The acquisition unit establishes a TCP/IP connection with the milling unit 

for the data transmission.
An Ethernet infrastructure is required for this.
This can be implemented by standard, wired LAN infrastructure, a WLAN, 

or the CEREC Radio Device system as described in this document.
