Bellalta, Boris2020-04-092020-04-092016Bellalta B. IEEE 802.11ax: high-efficiency WLANs. IEEE Wirel Commun. 2016 Mar 2;23(1):38-46. DOI: 10.1109/MWC.2016.74224041536-1284http://hdl.handle.net/10230/44196IEEE 802.11ax-2019 will replace both IEEE 802.11n-2009 and IEEE 802.11ac-2013 as the next high-throughput WLAN amendment. In this article, we review the expected future WLAN scenarios and use cases that justify the push for a new PHY/MAC IEEE 802.11 amendment. After that, we overview a set of new technical features that may be included in the IEEE 802.11ax-2019 amendment, and describe both their advantages and drawbacks. Finally, we discuss some of the network-level functionalities that are required to fully improve the user experience in next-generation WLANs and note their relation with other ongoing IEEE 802.11 amendments.application/pdfeng© 2016 IEEE.
