Spectrum Management (Fixed Frequency)
The PTP 500 Series Bridge 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 Section
8.3.4.3 "Wireless Configuration"). 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 62.
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.
