IEEE 802.11af, also referred to as White-Fi and Super Wi-Fi, [1] [2] is a wireless computer networking standard in the 802.11 family, that allows wireless local area network (WLAN) operation in TV white space spectrum in the VHF and UHF bands between 54 and 790 MHz. [3] The standard was approved in February 2014. [4]
Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks . It operates in the 2.4 GHz and 5 GHz bands, [ 9 ] with an extended version, Wi-Fi 6E , that adds the 6 GHz band. [ 10 ]
802.11g is the third modulation standard for wireless LANs.It works in the 2.4 GHz band (like 802.11b) but operates at a maximum raw data rate of 54 Mbit/s.Using the CSMA/CA transmission scheme, 31.4 Mbit/s [9] is the maximum net throughput possible for packets of 1500 bytes in size and a 54 Mbit/s wireless rate (identical to 802.11a core, except for some additional legacy overhead for ...
IEEE 802.11be, dubbed Extremely High Throughput (EHT), is a wireless networking standard in the IEEE 802.11 set of protocols [9] [10] which is designated Wi-Fi 7 by the Wi-Fi Alliance. [ 11 ] [ 12 ] [ 13 ] It has built upon 802.11ax , focusing on WLAN indoor and outdoor operation with stationary and pedestrian speeds in the 2.4, 5, and 6 GHz ...
IEEE 802.11ah is a wireless networking protocol published in 2017 [1] called Wi-Fi HaLow [2] [3] [4] (/ ˈ h eɪ ˌ l oʊ /) as an amendment of the IEEE 802.11-2007 wireless networking standard. It uses 900 MHz license-exempt bands to provide extended-range Wi-Fi networks, compared to conventional Wi-Fi networks operating in the 2.4 GHz , 5 GHz ...
IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. [d] The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance. [9] [10]
