In this article, we review the latest technical attributes such as orthogonal frequency division multiple access (OFDMA), multi-user MIMO (MU-MIMO) and enhanced clear channel assessment (CCA) for better spatial reuse used in the 802.11ax amendment to the 802.11 standard that leads to PHY and MAC enhancements for high-density scenarios of access points (APs). IEEE 802.11ax, also referred to as high-efficiency...
Legacy IEEE 802.11 fails to efficiently support multicast transmissions. To handle the rising need for multicast, which is typically forced to provide multimedia traffic, the IEEE 802.11aa Task Group (TGaa) has consistent cutting edge mechanisms meant for providing successful and robust transmission of multicast flows in wireless local area networks (WLAN). Still, the regular enables the utilization...
