Radio characteristics
This chapter describes some technical details about the radio which
might be required for more advanced setups when the system must
operate and coexist in an environment with several wireless systems.
6.7.1 Frequency spectrum
The CEREC Radio Device network units each receive a 2 MHz channel,
assigned to them in the 2.4 GHz band. The WLAN channels in this band
are illustrated in the figure below.
6.7.2 Channel control
Each network unit uses a specific channel on which it can receive data.
6.7.3 Channel switching
In order to avoid interference by other wireless devices, each network unit
continuously monitors the radio signals in the entire frequency band. The
unit can decide to switch to another (better) frequency channel in case its
data transmission suffers too much from interference in its own frequency
channel.
Connected Transfer The network unit has received data which it has to transmit. Data can be
received via the Ethernet connection or wirelessly from other network
units.
All Error A serious error has occurred.
