As the most popular technology, Wi-Fi is built based on Wi-Fi standards in many consumer areas. Up to now, Wi-Fi has experienced more than 20 years of development. The launch of the first generation protocol IEEE802.11 has a low popularity because it is not competitive in transmission speed and distance. With the proposal of the third generation 802.1g protocol, IEEE adds the backward compatibility feature to the new protocol. For 802.11 protocol, new technologies will be adopted in each iteration, so as to improve the network performance. Until the latest generation protocol, IEEE802.11ax launched in September 2019 has been called Wi-Fi 6.
Wi-Fi-6 has greatly improved its performance. It introduces uplink MU-MIMO, OFDM orthogonal frequency division multiple access, 1024-qam high-order modulation and other technologies to solve the problems of spectrum resource utilization and multi-user access. Even if Wi-Fi-6 continues every new WLAN standard for a long time and only makes the conventional upgrade of single stream throughput, the main motivation behind Wi-Fi-6 is to improve the experience quality of MU-MIMO users and achieve this goal by minimizing the overall delay. Therefore, higher spectrum and the effective and efficient sharing of the spectrum have become the key to achieve the minimum capacity.
This paper also puts forward some views on the cooperation between 5G and Wi-Fi-6. For Wi-Fi networks, it has a faster update cycle than mobile networks. In addition, when users' usage habits are formed, the possibility of Wi-Fi network being replaced is low. Although 5G and Wi-Fi-6 differ in performance, they have their own advantages. They are suitable for different scenarios. 5G will have better performance in outdoor open places, such as car networking, while indoor Wi-Fi network can meet the more economical demand for high-speed Internet access, such as VR, smart home, etc.
In the third chapter of this paper, it focuses on the demand of Wi-Fi-6 driven by the development of high-quality network connection and Internet of things.
First of all, when Wi-Fi-6 was designed, high-density and high-capacity network service support has been considered, which is also the reason for supporting Wi-Fi-6 to be used in outdoor large-scale public places, indoor high-density wireless office and electronic office. However, because 5g has more advantages in the application of outdoor environment, indoor is the key application scenario of Wi-Fi-6. It is also because people's demand for information consumption, entertainment and smart device links has promoted the development of Wi-Fi-6.
Secondly, the demand for high-quality network connection is prominent. With the promotion of national policies, it will help to speed up the construction of HD video content. As the main carrier of indoor transmission, Wi-Fi will be popularized more effectively when the terminal penetration continues to improve.
Thirdly, the demand for the Internet of things is gradually increasing. Unlike users such as laptops, IOT devices need deterministic wireless services. Therefore, enterprise Wi-Fi-6 has increasingly become the preferred platform for the indoor Internet of things. Compared with Wi-Fi-5 and 4G, Wi-Fi-6 has faster speed and can transmit data like lightning. Moreover, Wi-Fi-6 has improved in security and scalability respectively. The previous Wi-Fi router supports 250 devices to connect at the same time, but this is insignificant in front of Wi-Fi-6 that can support up to 1024 devices at the same time. Therefore, Wi-Fi-6 is ideal and economical for families and small businesses.
Finally, Wi-Fi-6 realizes the intelligent industrial scene. Although 5g and Wi-Fi-6 can now increase the rate to about 10gpbs due to technological improvements. However, because 5g network construction has just started, Wi-Fi-6 currently has greater advantages in the industrial field. Most factories have generally adopted wired network connection to realize Wi-Fi communication.
In the fourth chapter, this paper also summarizes the rapid expansion of Wi-Fi-6 market.
Today, the WLAN market is in a steady upward trend, and the Wi-Fi-6 application scenario is getting better. It is expected that the Wi-Fi-6 market will reach 24 billion yuan in 2023, which means that the chips supporting Wi-Fi-6 standards account for nearly 90% of the total. In terms of market segments, the market scale of router / gateway Wi-Fi-6 chip in China is about 300 million yuan in 2019 and is expected to exceed 4.5 billion yuan in 2023.
In the past two years, the development speed of Wi-Fi-6 is obvious to all. From new mobile phones of major brands to routers, products supporting Wi-Fi-6 technology continue to emerge.
