Origin of 802.11ax Technology

IEEE 802.11 is a working group in the IEEE responsible for the protocol standards for wireless local area networks. The organization has developed several successful WLAN protocols, such as 11g, 11n and 11ac.



802.11ac has provided a breakthrough of 1Gbps for WLAN link. However, with the wide application of WLAN applications, the number of APs and terminals is increasing, and the conflicts and interferences between devices may cause unsatisfactory efficiency result for the entire network. New application scenarios, such as video, production network, and automation technology, also put forward higher requirements for WLAN in terms of throughput, stability, and transmission latency. In response to the new challenges, the 802.11 working group established the HEW (High Efficiency Wireless) research group in 2013 and it became the official 11ax task group in 2014, developing the 11ax protocol based on the 802.11-2012 standard.
