There are two distinct approaches to spectrum planning:
First an operator can utilize the default spectrum management mode i-DFS
(intelligent Dynamic Frequency Selection). This mode uses the PTP 600 Series
Bridge ability to measure the interference levels in all channels to build up a picture of
the interference / noise levels in all channels. The PTP 600 Series Bridge uses
statistical techniques to select the most appropriate transmit and receive channels. I-
DFS can be influenced in its channel decision process by selectively barring channels
from use. The use of this functionality is described in detail in Section
989H8.3.7
990HSpectrum Management”.
Second, when detailed control of the spectrum allocation is required, it is
recommended that the fixed frequency mode is used to statically allocate transmit
and receive channels.
