System Configuration
The System configuration page lets you change the unit’s
System Name
,
Location
, and so on. In addition, this page provides a selectable
Country
field that automatically provides the allowed bandwidth and frequencies for the
selected country/band.
Units sold only in the United States are pre-configured to scan and display
only the outdoor frequencies permitted by the FCC. No other
Country
can be
configured. Units sold outside of the United States support the selection of a
Country
by the professional installer.
Notes:
Non-US installers should not add an antenna system until the
Country
is
selected, the unit is rebooted, and the proper power level is configured.
The output power level of the final channel selected by DFS scan can be
found in the Event Log.
dynamic.frequency.selection.(dfs)
The Tsunami 5012/5054-SUI supports Dynamic Frequency Selection (DFS) for
FCC, IC, and ETSI regulatory domains per FCC Part 15 Rules for U-NII devices,
IC RSS-210, and ETSI EN 301-893 and 302-502 regulations, respectively.
These rules and regulations require that 802.11a devices use DFS to prevent
interference with radar systems and other devices that already occupy the 5
GHz band.
Upon choosing a country/band on the
System
page, the Dynamic Frequency
Selection (DFS) and Transmit Power Control (TPC) features are enabled
automatically if the selected country/band has a regulatory domain that
requires it. The Country selection pre-selects and displays only the allowed
frequencies for the selected country/band.
transmit.Power.control
Transmit Power Control is a manual configuration selection to reduce the
output power in the radio. The maximum output power level for the operating
frequency can be found in the event log
of the unit embedded software.
ATPC (Automatic Transmit Power Control) is a feature to automatically adapt
transmit power when the quality of the link is more than sufficient to maintain
a good communication with reduced transmit power. This feature is required for
FCC DFS.
