Spectrum management (fixed frequency)
The PTP 600 Series software allows a user to optionally fix transmit and receive
frequencies for a wireless link. Once configured, the spectrum management software
will not attempt to move the wireless link to a channel with lower co and adjacent
channel interference. Therefore this mode of operation is only recommended for
deployments where the installer has a good understanding the prevailing interference
environment. (See Installation step 2 - wireless configuration on
page 6-59). Care must
also be taken to ensure that the frequency allocations at each end of the link are
compatible. To help the user when identifying the mode of operation Spectrum
Management uses two visual cues. See Figure 6-14. The
main page title identifies the
mode of operation using the “Fixed Frequency Mode” postfix and the selected
channels are identified by a red capital ‘F’.

Channel barring is disabled in fixed frequency mode; it is not required as dynamic
channel hopping is prohibited in this mode.
