Tsunami™ QB-8100 Series (50 Mbps / 12 Mbps)

Advanced Configuration4.4.6 MIMO PropertiesThe MIMO Properties screen allows you to configure the Multiple-Input-Multiple-Output radio to achieve maximumperformance and high throughput.To configure MIMO properties1. Click ADVANCED CONFIGURATION > Wireless > Interface1 > MIMO Properties. The MIMO Properties screenappears.Figure 4-8 MIMO Properties2. Enter the appropriate parameters on the MIMO Properties screen. See the following table that lists the parameters andtheir descriptions.3. Click OK.NOTE: When you modify MIMO parameters and click COMMIT, it may result in brief interruption of service.ParameterFrequency ExtensionGuard IntervalDescriptionConfiguration of this parameter is valid only if the channel bandwidth is 40 MHz. If UpperExtension Channel is selected, the radio automatically uses the current channel (20MHz) aswell as next upper adjacent channel (20 MHz) for data transmission. If Lower extensionchannel is selected, the radio automatically uses the current channel (20MHz) as well aslower adjacent channel (20 MHz) for data transmission.For example, if channel 36 is selected in 40 + mode, the radio uses 36 as well as next upperadjacent channel 40 also for data transmission, similarly if channel 40 is used in 40- mode,the radio uses 40 as well as the next lower adjacent channel 36 for data transmission.Possible values for Guard interval are Full GI-800 nSec and Short GI-400 nSec. Short GI-400nSec is valid only for 40 MHz channel bandwidth.Tsunami QB-8100 Series (50 Mbps / 12 Mbps) Installation and Management Guide 48
