This chapter lists the components and component level changes required to support the dual workstation feature .

The following is what needs to be changed to support dual STA Module / Components :

1. Framework overlay configurations for dual STA

2. Wifi Manager APIs enhancement for dual STA

3. Wifi Service enhancement to support dual STA

4. WifiHAL combination to allow STA + STA

2.1 Framework overlay configurations for Dual STA 
This section discusses dealing with double STA The logo of / To configure

1.WifiHal Feature flags allow double STA Combination support ( Build time ). This is device specific / Defined in the generation file of the target ( Usually wlan.mk)
