●
WLAN Mode
Select the required transmission standard for the configured frequency band.
– WLAN Mode 2.4 GHz
Specify the transmission standard for the 2.4 GHz frequency band.
– WLAN Mode 5 GHz
Specify the transmission standard for the 5 GHz frequency band. The selection
depends on the country setting.
●
DFS (802.11h)
– Enabled
If the access point discovers a disruption on the current channel, for example due to a
primary user, it automatically switches to an alternative channel. You specify the
alternative channel on the "AP Settings" Basic Wizard page. DFS is also required for
the use of certain wireless channels. This can only be enabled in the 5 GHz band.
– Disabled
The DFS function is not used.
●
Outdoor Mode
– Enabled
In outdoor mode, the selection of country-dependent channels and the transmit power
for operation are extended for outdoor use.
– Disabled
The device is being operated in indoor mode. In indoor mode, the selection of country-
dependent channels and the transmit power for operation in a building are restricted.
●
max. Tx Power
Specify the transmit power of the device. It may be necessary to reduce the transmit
power depending on the antennas being used to avoid exceeding the maximum legal
transmit power. Reducing the transmit power effectively reduces cell size
Note
The maximum possible transmit power varies depending on the channel and data rate.
For more detailed information on transmit power, refer to the documentation
"Characteristics radio interface".
●
Tx Power Check
Indicates whether the settings that have been made will violate the permitted transmit
power restrictions of the selected country. The following parameters influence this
calculation:
max. Tx Power, Antenna Gain, Additional Attenuation.
The following displays can appear:
– Allowed
The channels can be used with the current settings.
– Not Allowed (Some Channels)
Among the channels, there are some on which the current transmit power exceeds the
maximum permitted transmit power.
– Not Allowed (All Channels)
No permitted operation is possible. The transmit power is too high.
