After configuring the required MIMO parameters, click OK and then COMMIT.

The  Frequency Filter tab allows you to configure the lower and upper frequency band edges, which helps to limit the
available frequency band, for a given frequency domain, to a smaller band. By limiting the frequency band, the time taken by
a device to scan and connect to any other device in the network is reduced. The Frequency Filter Configuration screen
appears as shown below.

The frequency range limit for the filter lower and upper edge is 0 - 10000 MHz; by default, the lower frequency edge is set to
0 MHz and the upper frequency edge is set to 10000 MHz. Configure the values and Click OK and then COMMIT.

Guard Interval

Guard Interval determines the space between symbols being transmitted. The guard 
interval can be configured as either Short GI - 400n seconds or Full GI-800n seconds.

In 802.11 standards, when 40 MHz Channel Bandwidth is configured then Short GI can be 
used to improve the overall performance and throughout.

By default, Full GI is enabled for 5 MHz, 10 MHz and 20 MHz channels.
