14MCEI25 Nirma University PAGE 1 Abstract This paper gives an overview of a number of advanced wireless LAN technologies. IEEE 802.11ac introduced multiuser access in the form of Downlink Multi-User Multiple Input Multiple Output (DL MU-MIMO), dynamic or static channel bandwidth operation, and 80 MHz, 160 and 80+80 MHz channels in the 5 GHz band. As a result, 802.11ac advances wireless LAN throughput beyond gigabit rates. Going forward, IEEE 802.11, within the 802.11ax task group, is evaluating more advanced wireless technologies such as simultaneous transmit/receive (STR), downlink and uplink Orthogonal Frequency Division Multiple Access (OFDMA), Uplink MU-MIMO, and dynamic Clear Channel Assessment (CCA). Introduction Mobile data traffic grew 80% last year and it is estimated that it will grow 10 times between 2013-2018. By 2018 2/3rdof the mobile traffic will be video and half of the traffic will be offloaded onto Wi-Fi networks. IEEE is developing standards for new high speed specifications like 802.11ac, 802.11ad, 802.11ax and others. WiGig was established to carry research in 802.11ad specifications which operates in Giga Hertz frequency band. Wi-Fi Alliance took over WiGig and merged it with itself. In this paper 802.11ac, 802.11ad and 802.11ax specifications are explained.
