Therefore, the Wi-Fi Alliance (WFA) defines 802.11ac into two releases to release it to the market: Wave 1 and Wave 2. It will take a long time to release Wi-Fi products using all these technologies to the market. 802.11ac is innovated in a large number of technologies. To meet the preceding requirements, the fifth-generation 802.11 standard is developed. The Wi-Fi network is required to provide larger capacity and more user access. In the case of explosive increase of data services in the cellular system, more traffic is load balanced on the Wi-Fi network to reduce the load of the cellular system.

In football fields, new product conference sites, or classrooms, concurrent access of many users poses a serious challenge to 802.11n products.Each terminal consumes network resources. Facing the BYOD trend, each employee may have two or more Wi-Fi terminals.As predicted by Ericsson, video traffic on the mobile network will increase by 60% every year until the end of 2018 when video traffic will account for half of global mobile data traffic. The applications propose high bandwidth for Wi-Fi. Video services for product and solution promotion by more and more enterprises.Video conference services transferred from fixed devices to mobile devices.Vine (Twitter) video shooting and sharing application services.

Large-bandwidth applications are widely used in Wi-Fi: In practice, 802.11n products face the following challenges: As wired Ethernet GE access gradually goes mainstream, Wi-Fi needs to provide good user and service experience. The wired Ethernet and applications drive 802.11ac development.
