Short Name: MAC Header HT Control
Property of niWLANGeneration
Specifies the four-byte HT Control field as defined in section 7.1.3 of IEEE Standard 802.11n-2009, section 8.2.4 of IEEE Standard 802.11ac-2013 and IEEE P802.11ah/D1.3, and section 9.2.4 of IEEE P802.11ax/D6.0. This field is represented with the least significant bit in the rightmost position.
You must use the following active channel string formats to configure this property.
| Standard Property Value | Active Channel String Format |
|---|---|
| 80211A/G OFDM, 80211J OFDM, 80211P OFDM, 80211B/G DSSS, 80211G DSSSOFDM | "" (empty string) |
| 80211N MIMOOFDM, 80211AH MIMOOFDM | "", if you set the A-MPDU Enabled property to False |
| "mpdux", If you set the A-MPDU Enabled property to True | |
| 80211AC MIMOOFDM | "", if you set the PPDU Type property to SU PPDU and the A-MPDU Enabled property to False |
| "mpdux", if you set the PPDU Type property to SU PPDU and the A-MPDU Enabled property to True | |
| "userx/mpduy", if you set the PPDU Type property to MU PPDU and the A-MPDU Enabled property to True | |
| 80211AF MIMOOFDM | "" (empty string), if you set the PPDU Type property to SU PPDU and the A-MPDU Enabled property to False |
| "mpdux", if you set the PPDU Type property to SU PPDU and the A-MPDU Enabled property to True | |
| 80211AX MIMOOFDM | "" (empty string), if you set the PPDU Type property to SU PPDU or Extended Range SU PPDU and the A-MPDU Enabled property to False |
| "mpdux", if you set the PPDU Type property to SU PPDU or Extended Range SU PPDU and the A-MPDU Enabled property to True | |
| "userx/mpduy", if you set the PPDU Type property to MU PPDU or Trigger-Based PPDU and the A-MPDU Enabled property to True |
 |
Note The toolkit ignores this property if you set the MAC Frame Format property to Short. |
The default value is 0x0. Valid values are 0x0 to 0xFFFFFFFF. For values outside this range, the toolkit uses the least significant four bytes.
The toolkit ignores this property if you set the MAC Frame Type property to Trigger Frame.
