CEREC Radio Device network overview
The network units in the CEREC Radio Device network create a so-called
peer-to-peer mesh network. This means that there is not a master or
slave as with Bluetooth, nor a central controlling access point for the
control as with WLANs.
As such there is no distinction between a network unit connected to a
milling unit, one that is built into an acquisition unit, or one that is
connected to LAN infrastructure: any network unit belonging to the same
network (see “Creating a network [ → 18]”) can communicate with all other
network units in this network that are in range. This is also applicable
when they are out of range of all other network units, making establishing
network connections very flexible.
The wireless network operates in the 2.4GHz band which is available
worldwide for license-free operation. It therefore needs to be able to
communicate with other wireless networks such as WLAN or Bluetooth
networks. The network accomplishes this by avoiding congested
channels wherever possible. However, the network is not completely
immune to interferences caused by other wireless technologies. The
result of these interferences can be a reduced range and drops in
performance. The network technology therefore offers several easy
mechanisms with which a network can be extended to achieve better
coverage (see “Extending the network [ → 20]”).
The network can also easily be extended and the coverage increased,
using LAN cables or even an existing LAN infrastructure (see “Increasing
the range [ → 30]”).
6.2
Creating a network
Network units that come out of the box have never been part of a network.
To allow for several networks of different owners to operate side-by-side
or in the same area, new network units must first create a network. This
is described in the following section.
