Wi-Fi 6

802.11 ax is a type of WLAN in the IEEE 802.11 set of types of WLANs. It is still in a very early stage of development, but it is predicted to have a top speed of around 10 Gbit/s^[1](as tested by Huawei), have a frequency of 2.4 and/or 5 GHz and have a MIMO-OFDM modulation. It is due to be publicly released in 2019.

Notes

^ A second stream doubles the theoretical data rate, a third one triples it, etc.
^ MCS 9 is not applicable to all channel width/spatial stream combinations.
^ GI stands for the guard interval.
