802.11ax access points that support 1024-QAM have new modulation and coding schemes (MCS) that define higher data rates. As with 256-QAM, 802.11ax APs will need very high SNR thresholds (~35 dB) to use 1024-QAM modulation. 

In the table, the individual Modulations and the signal levels and SNR (signal to noise ratio) required for them are shown.
