Subcarrier Spacing (Pre-HE) (802.11n/ac/ax/be)
The parameter specifies the subcarrier spacing of the 802.11ax/be signal's symbols prior to HE-STF. The subcarrier spacing must match the input signal value. However, the value can be adjusted for troubleshooting purposes or to match a custom or nonstandard subcarrier spacing.
For an HE PPDU PLCP Protocol data unit, the subcarrier spacing of each part in the PPDU are not unanimous. For an HE SU Single user PPDU, the subcarrier spacing of the symbols prior to HE-STF is 312.5 kHz kiloHertz: A radio frequency measurement (one kilohertz = one thousand cycles per second)., which is four times that of the symbols of HE-STF, HE-LTF Long Training field, and data.
is only visible for the 802.11ax/be standard formats. For 802.11n/ac standard formats, see Subcarrier Spacing.
Default: 312.5 kHz.
