Towards the end of 2020, the most exciting industry development is undoubtedly the gradual popularization of 5G and the launch of WiFi6 terminal products. Use 5G outdoors and WiFi 6 indoors to enjoy high-speed surfing. 

It is foreseeable that the latest generation of WiFi6 technology will bring an innovation to indoor wireless networks, completely change the realization of the Internet of Things and smart homes, and give people an unprecedented network experience. The update iteration of WiFi development, like the development of 2G~5G, is also a process of gradually satisfying the market, and at the same time has spawned the rise of a number of new fields. So far, there is no related WiFi6 module product on the market. Hi-Link will launch WiFi6 module products in the near future to fill the gap in the market and meet the needs. We welcome continued attention. Hi-Link Official WeChat: HLKtech09

The development of WiFi technology has a history of 20 years, from the first generation of 802.11b to 802.11a, 802.11g, 802.11n (WiFi4), 802.11ac (WiFi5), and the current 802.11ax (WiFi6). With the development of technology and products, users have higher and higher requirements for speed, and product changes are getting faster and faster. The latest generation of WiFi6 has a transmission rate between 1G and 10G, which can cover more diversified applications. . The following figure can intuitively illustrate the difference between several different WiFi specifications.

 

From the above picture, we can see that the advantages of WiFi6 are self-evident. With the development of the times, people have more and more wireless devices around them, and they have become overcrowded. WiFi6 can well improve the signal strength in crowded areas (such as the city center or crowded houses). The speed of WiFi6 will be increased by 4 times, and its theoretical speed can reach 9.6Gbps, which is converted into a commonly used download speed of 1.2G/S, and provides greater bandwidth.

802.11ax will greatly increase the average transmission rate of each user in a user-intensive environment, that is, provide more users with a consistent and stable data stream (average transmission rate) in a high-density environment, which will effectively reduce network congestion and greatly improve wireless Speed and coverage. In fact, the primary purpose of designing 802.11ax is to solve the problem of network capacity, because as network equipment becomes more and more daily life, the problem of network capacity has become a major obstacle to the realization of the Internet of Everything.

There is another solution to solve network congestion, which is to use equipment in the wrong frequency band. The 802.11ax protocol is based on two frequency bands of 2.4GHz and 5GHz, and it supports both frequency bands. This obviously caters to the current development trends of the Internet of Things and smart homes. For some smart home devices that do not require high bandwidth, you can use the 2.4GHz frequency band to connect to ensure sufficient transmission distance, and for devices that require high-speed transmission, use the 5GHz frequency band.

The new wireless standard is expected to revolutionize the Internet of Things with amazing speed, low power consumption requirements and high bandwidth. Hi-Link will soon launch module products that belong to the 802.11ax protocol, which will be well compatible with 802.11a/b/g/n /ac. Customers who have higher requirements for transmission rate and transmission bandwidth. 2021 will become a watershed for the Internet of Things (IoT), and Hi-Link’s WiFi6 module products are bound to be bullish!
