802.11ac vs 802.11ax-Difference between 802.11ac,802.11ax
This page compares WLAN 802.11ac vs 802.11ax and mentions difference between 802.11ac and 802.11ax.
This WLAN standard is successor to IEEE 802.11n.
It supports high throughput due to addition of higher bandwidths, multi-user MIMO, higher number of spatial streams and
higher number of modulation schemes such as 256 QAM.

This WLAN standard is successor to IEEE 802.11ac. In addition to higher speed, 802.11ax offers greater coverage range compare to legacy wifi networks such as 802.11a/g/n/ac.
It has advanced features such as downlink and uplink OFDMA,
Uplink resource scheduling without any contention unlike 802.11ac, MU-MIMO (DL and UL),
Long OFDM symbol, higher modulation scheme (1024-QAM), More spatial streams (up to 8),
support for 2.4 GHz and 5 GHz both, BSS coloring etc.
