Hello, everyone!
Today, I would like to share an introduction on the IEEE 802.11ax amendment.
In 2014, the High Efficiency WLANs (HEW) Task Group began work on an amendment to IEEE 802.11ax. The IEEE 802.11ax amendment is the IEEE 802.11 response to future congested WLAN and high-bandwidth demand environments.
Some of the open difficulties being investigated in the development of the IEEE 802.11ax amendment are as follows:
Enhance WLAN performance by giving at least a four-fold capacity gain over IEEE 802.11ac.
Facilitate dense networks by accounting for several overlapping WLANs and multiple STAs in each one. The entire transmission material must be reused.
To make optimal use of transmission resources, reduce the exchange of management and control packets, rewrite the packet structure, and optimize channel access and retransmission procedures, among several other things.
It is necessary to maintain backward compatibility with past iterations. This is accomplished by mandating the transmission of the legacy PHY preamble in all frames and keeping EDCA as the primary channel access method.
Implement efficient energy-saving mechanisms to reduce energy consumption.
Support multi-user transmission techniques in both the downlink and uplink by improving MU-MIMO and Orthogonal Frequency Division Multiple Access (OFDMA) functionalities.
