The difference between Wi-Fi AC And AX-IEEE 802.11ax (Wi-Fi 6)

- Jul 15, 2020-

Whats Wi-Fi ac?


IEEE 802.11ac is a wireless network standard of 802.11 families, It was formulated by the IEEE Standards Association and provides high-throughput wireless local area networks (WLANs) through the 5GHz band, commonly called as 5G Wi-Fi (5th Generation of Wi-Fi).


Theory, it can provide a minimum of 1Gbps bandwidth for multiple-station wireless LAN communication or a minimum transmission bandwidth of 500Mbps for a single connection.


802.11ac is the successor of 802.11n. It adopts and extends the concept of air interface derived from 802.11n, including wider RF bandwidth (up to 160MHz), more MIMO spatial streams (up to 8), downlink multi-user MIMO (up to 4), and high-density modulation (up to 256-QAM).


Whats Wi-Fi ax?


IEEE 802.11ax (Wi-Fi 6) is also known as High-Efficiency Wireless(HEW).


IEEE 802.11ax supports 2.4GHz and 5GHz frequency bands and is backward compatible with 802.11 a/b/g/n/ac. The goal is to support indoor and outdoor scenarios, improve spectrum efficiency, and increase actual throughput by 4 times in dense user environments.


Wi-Fi ax main features:


*Compatible with 802.11 a/b/g/n/ac


*Upstream and downstream OFDMA

*Upstream MU-MIMO

*4 times OFDM symbol duration

*Adaptive Idle Channel Assessment
