Chapter 3: System planning Radio spectrum planning
Available spectrum
The available spectrum for operation depends on the regulatory band. When configured with the
appropriate license key, the unit will only allow operation on those channels which are permitted
by the regulations.
Note
In Italy, general authorization is required for any 5.4 GHz radio link that is used outside
the operator’s own premises. It is the responsibility of the installer or operator to have
the link authorized. Details may be found at:

Certain regulations have allocated certain channels as unavailable for use:
• ETSI has allocated part of the 5.4 GHz band to weather radar.
• UK and some other European countries have allocated part of the 5.8 GHz band to Road
Transport and Traffic Telematics (RTTT) systems.
The number and identity of channels barred by the license key and regulatory band is dependent
on the channel bandwidth and channel raster selected.
Barred channels are indicated by a “No Entry” symbol displayed on the Spectrum Management
web page (Spectrum management in radar avoidance mode on page 7-27).
Channel bandwidth
Select the required channel bandwidth for the link. The selection depends upon the regulatory
band selected.
The wider the channel bandwidth, the greater the capacity. As narrower channel bandwidths take
up less spectrum, selecting a narrow channel bandwidth may be a better choice when operating in
locations where the spectrum is very busy.
Both ends of the link must be configured to operate on the same channel bandwidth.
