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 maximum possible 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".
Note
If both interfaces of access points with two WLAN interfaces are
operated in the same
frequency range, this may cause wireless interference on one or both interfaces at a
transmit power higher than 15 dBm.
●
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.
Procedure
1. To configure the WLAN interface, you must always specify the country first. Select the
country in which the device will be operated from the Country Code drop-down list.
2. Select the required frequency band from the "Frequency Band" drop-down list.
3. Select the required transmission standard for the configured frequency band from the
"WLAN Mode" drop-down list.
4. Click the "Set Values" button.
