Discuss how the various 802.11 standards apply to the provision of Wi-Fi
What will be an ideal response?
802.11 are evolving standards for high-speed, fixed broadband wireless local area networks (Wi-Fi) for commercial and residential use. Wi-Fi provided under the 802.11 specifications offers high-bandwidth capacity from 11 Mbps up to a maximum of 7 Gbps, far greater than any 3G or 4G cellular service currently in existence, but has a limited range of 300 meters. IEEE 802.11ac is a version of the 802.11 specification adopted in 2013 that provides for throughputs of between 500 Mbps to over 1 Gbps. The newest standard, IEEE 802.11ad provides for throughput up to 7 Gbps. The first 802.11ad devices began shipping in 2016. Next-generation Wi-Fi standards currently being worked on by the IEEE 802.11 Working Group include 802.11ay, which deals with 60 Ghz wireless operations, and will provide for data rates of up to 20 Gbps, and 802.11ax, aimed at high-efficiency WLANs used for stadiums and other areas where many people want to access a Wi-Fi network at the same time. A next-generation 802.11ah standard aimed at the Internet of Things is also being developed.
