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:
Actor Description
Acquisition The PC platform that is used to
unit acquire the dental data.
Network A wireless transceiver that has an
unit Ethernet connector. The Ethernet
socket also has LEDs to indicate
the status.
Mobile A network unit which is installed
network inside an acquisition unit.
unit
Stationary A network unit is either attached to
network the milling unit directly or
unit connected to a LAN.
Milling unit Receives the data and processes it
to mill a restoration.
Operator Person possessing technical
knowledge (either by experience,
instruction or education) about the
operational details of the network.
Dentist User who does not possess any
technical knowledge about the
working of the network.
Role
Data source. Initiates the
transmission to a milling
unit.
Wireless node in the
network.
The network unit for the
acquisition unit.
Wireless end-point for the
data communication to
the milling unit.
Data receiver.
Performs all
infrastructural changes to
the network using
technical knowledge.
Uses the network to
transmit data.
