Spectrum Management Configuration
The following section describes the user modifiable configuration accessible from the
Spectrum Management webpage. It is recommended that the default values are maintained.
If the user believes that the performance of the Spectrum Management algorithm requires
some modifications this should only be done after consulting your Motorola Point-to-Point
distributor or one of the system field support engineers.
Refresh Page Period:
The page refreshes automatically according to the setting entered
here (in seconds).
Hopping Margin:
Spectrum Management uses this margin when making a channel hop
decision. The target channel has to have an interference level 3 dB (default) better than the
current active channel.
Hopping Period:
The Spectrum Management algorithm evaluates the metrics every
‘Hopping Period’ seconds (180 seconds by default) looking for a channel with lower levels of
interference. If a better channel is located, Spectrum Management performs an automated
channel hop. If SNMP or SMTP alerts are enabled an SNMP TRAP or an email alert is sent
warning the system administrator of the channel change.
Hopping Counter:
is used to record the number of channel hops. The number in the “(+)”
brackets indicates the number of channel changes since the last screen refresh.
Interference Threshold:
Spectrum Management uses the interference threshold to perform
instantaneous channel hops. If the measured interference on a channel exceeds the specified
threshold, then iDFS will instruct the wireless to immediately move to a better channel. If a
better channel cannot be found the 600 Series bridge will continue to use the current active
channel. (Default –85 dBm)
Asymmetric DFS:
The default configuration of symmetric operation constrains the link to
operate symmetrically, using the same transmit and receive channels. When in symmetric
mode the slave unit will always follow the master. If the master moves to a new channel the
slave will hop to the same channel. When the Point-to-Point link is configured as an
asymmetric link both the master and slave are free to select the best channel from their own
set of local interference metrics.
