Description
Table 1 has the following columns:
● Radio
Specifies the WLAN interface to which the information relates.
● Use selected data rates only
If you select this option, you can specify the data transmission speeds for the required
WLAN interface.
If this option is disabled, the default values are used. As default, this option is disabled.
Drop-down list "Radio"
In this drop-down list, select the WLAN interfaces displayed in Table 3 (MCS Index).
With Table 2, you can enable or disable all check boxes of a column of Table 3 (MCS Index)

Table 3 (MCS Index) consists of the following columns:
● Radio
Specifies the WLAN interface to which the information relates.
● MCS Index
Shows the supported MCS indexes. The displayed MCS indexes depend on the settings
"Antenna Type" and "Antenna Mode". You will find the settings in "Interfaces > WLAN >
Antennas". If, for example, you only use one antenna, only the MCS 0 to 7 are displayed.
● Streams
Shows the maximum possible number of parallel data streams that can be transmitted
with the selected MCS index.
● Data Rate [Mbps]
Shows the supported data transmission speeds in megabits per second. The displayed
data transmission speeds depend on the settings "Guard Interval" and "HT Channel
Width". The "HT Channel Width" setting can be found in "Interfaces > WLAN > AP". The
"Guard Interval" setting can be found in "Interfaces > WLAN > 802.11n"
● Enabled
Enable the option to assign the required data transmission speed to the WLAN interface.
Note
You need to enable at least one MCS index.
