Short Name: Number of Space Time Streams
Property of niWLANAnalysis
Specifies the number of space time streams if you set the Standard property to 80211N MIMOOFDM, 80211AC MIMOOFDM, or 80211AX MIMOOFDM. This property is ignored if you set the Standard property to 80211N MIMOOFDM and the OFDM Combined Signal Demodulation Enabled property to False.
You must use the following active channel string formats to configure this property.
| Standard Property Value | PPDU Type | Active Channel String Format |
|---|---|---|
| 80211N MIMOFDM, 80211AF MIMOFDM | — | "" (empty string) |
| 80211AC MIMOFDM | SU PPDU | "" (empty string) |
| MU PPDU | "userx" | |
| 80211AX MIMOFDM | SU PPDU, Extended Range SU PPDU | "" (empty string) |
| MU PPDU, Trigger-Based PPDU | "userx" |
The default value is 1.
The allowed values for this property are as follows. All values are inclusive.
| Standard Property Value | Number of Space Time Streams property |
|---|---|
| 802.11N MIMOOFDM | 1 to 4 |
| 802.11AC MIMOOFDM | 1 to 8, if you set the PPDU Type to SU PPDU |
| 1 to 4, if you set the PPDU Type to MU PPDU | |
| 802.11AX MIMOOFDM | 1 to 8, if you set the PPDU Type to SU PPDU |
| 1 to 4, if you set the PPDU Type to MU PPDU or Trigger-Based PPDU | |
| 1 to 2, if you set the PPDU Type to Extended Range SU PPDU |
