Qualcomm WLAN framework learning (29) -- 6GHz overview

■ Support about 60 A new one 20 MHz channel , Range from 5925MHz To 7125MHz

■ Bandwidth support 20/40/80/ 160MHz bandwidth , Just like the existing 5 GHz Frequency band . 

■ The basic problem is that the channel number is different from the existing 2.4 GHz and 5 GHz The channel numbers of frequency bands overlap . for example , Channel number 1.2、3… And 2.4 GHz Band overlap , Channel number 36、40、44 And so on 5 GHz Band overlap .

■ The solution is either to use a unique frequency to identify the channel , Or use a pair ( Channel number , Operation class ) To identify the channel .

■ The global operational level of these new channels is 130-135.

■ Channel frequency MHz = 5940 +( Number of channels )x 5, Applicable to all global operation levels 130-135. 6 GHz The band is about 60 A new one 20 Megahertz channel .

■ 350 MHz The spectrum is for indoor use only , No restrictions .

27.1 Automatic frequency control (AFC) operation

27.2 Non automatic frequency conversion control operation

The following is the method of non automated frequency control operation :

Indoor low power consumption (LPI)

■ Low power operation :EIRP around 24 dBm(250 milli-watts) for Client.

■ The equipment is configured in an indoor environment .

■INI gindoor_channel_support Used for static configuration of indoor channels .

27.3 6GHZ Find out (STA scanning )

■ Minimize channel pollution caused by uncontrolled active scanning , Minimize scanning delay .
