IEEE 802.11ax: An Overview of High-Efficiency Wi-Fi (Wi-Fi 6) Medium Access Control Layer
In this course, learners will gain an overview of the features and optimizations introduced by IEEE 802.11ax to the Medium Access Control Layer (MAC), which lead to efficiency improvements.
IEEE Std 802.11ax is the latest step in a journey of continuous innovation in the wireless local area networks (LAN) standards and is the underlying technology of the latest Wi-Fi 6 products. Unlike previous amendments (e.g., IEEE Std 802.11ac, IEEE Std 802.11n) which were focused mainly on increasing the peak throughput, 802.11ax focuses on achieving Higher Efficiency (HE) and improving metrics that reflect user experience, such as average throughput per station. This was achieved by better physical layer efficiency and spectrum utilization, flexible multi-access and scheduled transmission schemes, increasing the spatial reuse, and improving interference management between neighboring networks, particularly in dense environments.
What you will learn:
- Explain how uplink (UL) and downlink (DL) multi-user (MU) operations work, and the different components that enable multi-user frame exchanges
- Review newly defined feedback mechanisms that support MU and improve its performance
- Summarize frame aggregation options available for 802.11ax
- Describe how dynamic fragmentation works
- Consider power saving protocols introduced in 802.11ax
- Summarize enhancements for operation in the 6 GHz band
