8.3.9 Spectrum Management - Fixed Frequency
The software for the PTP 400 Series Bridge 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 of the prevailing interference environment. (See
Section
8.3.5.3 “Wireless Configuration” - Fixed Transmit Frequency, Fixed Receive
Frequency). 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’.
