Insert section 7.3.2.61: VHT Capabilities element VHT Capabilities element structure A VHT STA declares that it is a VHT STA by transmitting the VHT Capabilities element. The VHT Capabilities element contains a number of fields that are used to advertise additional optional VHT capabilities of a VHT STA. The VHT Capabilities element is present in Beacon, Association Request, Association Response, Reassociation Request, Reassociation Response, Probe Request, and Probe Response frames. The VHT Capabilities element is defined in Figure 75.
