As a veteran driver in the industry for many years, I think it is a bit one-sided to say "substitution" directly. after all, considering the special network environment such as "dedicated network" and "public-private separation", the wired network will not disappear in the short term. But with the rise of BYOD, mobile phone has changed from a simple communication tool in the traditional sense to an intelligent terminal that integrates communication, work, entertainment, consumption, positioning and navigation. In fact, the core reason for the development of this situation is the continuous development of wireless networks, and the large-scale commercial use of 802.11ax will also play a role.

Why can we think so highly of 802.11ax technology? At the product launch of Ruijie Network, which I just attended recently, I saw several sets of data to share with you: 802.11ax proposed a new DCCA/DTPC spatial multiplexing technology, which can quickly identify empty port conflicts and back off. At the same time, by means of dynamic idle channel evaluation and dynamic power control, the average throughput in a multi-AP multi-user environment is 30% higher than that of the 802.11ac standard. Secondly, in addition to inheriting the MU-MIMO technology, another important innovation of 802.11ax is the introduction of OFDMA. In a typical multi-user concurrency scenario, the performance of the whole network can be improved by up to 3 times.

The improvement in data efficiency is really not the slightest bit, and some people may still question whether it is "talk on paper". It is understood that the Ruijie WIS wireless intelligence system, which uses some related technologies, has been implemented and verified in super-large-scale exhibitions such as Aliyunqi Conference, Tencent partner Conference, GITC Global Internet Conference, and SUNING Summer, and has achieved good results. Therefore, from the birth of 802.11 technology in 1997 to the Internet of everything today, 802.11ax accumulated in the past 20 years not only has amazing performance, but also has a wider application space, and its Wi-Fi application scene will be unprecedented.

It is well known that in the world of the Internet of everything, "Wi-Fi" is the key to ecosystems. And your office scene will also change, unlike now limited to a fixed station, then the use of cable network will be greatly limited, and these new office scenes, wireless network will be greatly adapted. You can imagine that when you work in high-density scenes such as offices, stations, airports, parks, stadiums and mass conferences, 802.11ax technology will bring you an unprecedented wireless experience and completely bid farewell to the Internet experience of "disconnection, disconnection and slow speed".
