Why Wi-Fi 6 (IEEE802.11ax) will be different than previous Wi-Fis?

The AP schedules the transmission according to the actual needs, and nobody wastes time on waiting and on collision. So, we end-up having the system that: is more robust towards low latency services; is more spectrally efficient; allows for actually use some QoS profiles; and coordinates the use of spectrum.

Wi-Fi Generations – new naming convention for WiFi

Wi-Fi Generations affect not only new releases, but also refer to the past amendments. Currently Wi-Fi Alliance has defined 6 generations. Each step is significant improvement in network performance and security. No more minor version changes that can cause only confusion.

Step in another direction in Wi-Fi? IEEE 802.11ax (High Efficiency WLAN)

The 802.11ax brings important features, focusing on network capacity, latency and range. High data rates are still in the picture, but rather in the background. Introducing OFDMA and using MU-MIMO allows AP to schedule data for multiple users simultaneously. This way, latency can be greatly decreased. With the new colors of the channels, frequencies can be spatially reused.
