The following table lists the 5.8 GHz channels available in North America.
Table 15: Web - North America RF Channels
T-54 Radio: 5.4* GHz T-58 Radio: 5.8 GHz T-58e Radio: 5.8 GHz
5.480 to 5.715
(steps of 5 MHz)
5.735 to 5.815
(steps of 5 MHz)
5.735 to 5.840
(steps of 5 MHz)
*Pending regulatory approval for some regions.
Auto scan : Automatically scan spectrum to locate frequency of PMP Master
(sector controller). This selection is only available when system is configured as a
PMP Slave (subscriber station).
Registration Period [frames] : The number of data frames transmitted between
registration periods. For example, a setting of '16' would transmit sixteen frames of
user data and then check for new subscriber stations.
Max. Distance [km] : Enter the distance to the farthest subscriber station. This
setting is used to calculate the registration period required to accommodate all
subscribers within that range.
Radio Enable : Check this box to enable the radio transmitter.
DFS Action : Select the mode of operation for DFS.
Important : Where required by regional regulations, DFS is enabled by the system
options key and cannot be disabled.
The system set to master-mode monitors for interference from radar devices and
other equipment using the same channel frequency. When interference is detected,
the system automatically takes the action selected using the drop-down menu:
None : The DFS function is disabled.
Tx Off : Transmission is immediately disabled when radar signals are detected.
This action is recorded in the message log and an SNMP trap message is sent
(SNMP enabled).
Following an interval of thirty minutes, the same channel is monitored for one
minute and if there are no DFS triggering events, the system resumes normal
operation. If DFS trigger conditions are still detected, operation is suspended
for an additional thirty minutes. This cycle continues until no DFS trigger
events are detected or the operator manually reconfigures the system.
Chg Freq : Relocate transmission to an alternative frequency immediately when
radar signals are detected. This action is recorded in the message log and a trap
message is sent (if SNMP enabled).
The new channel is selected based on allowable frequencies for the regulatory
region of that installation. The channel is monitored for one minute before the
system is allowed to transmit. If DFS triggering events are detected, the next
available channel is selected and monitored. The system is not allowed to
return to a channel on which DFS trigger events were detected for a period of
thirty minutes. If DFS trigger events are detected on all channels, operation is
suspended until the thirty-minute time interval expires for at least one channel.
Note: This hardware-enabled feature is not available on the AN-50.
