n addition to supporting 5G, the 2020 flagship machine is also equipped with another innovative technology in the field of communication technology-WiFi 6 standards. Why do the recently released mobile phones use this technology one after another? Where is WiFi 6 technology? What is the relationship between it and the popular 5G network? 01 Where is the Wi-Fi 6 technology? Wi-Fi 6 is an indispensable role in modern people’s lives. To give a simple example, in daily life, friends who visit their own homes will usually ask a question: “What is your WiFi password?” Someone might Will ask with the popularity of 5G, is Wi-Fi really unnecessary? The answer is of course no. Although 5G networks have many advantages, considering the indoor environment, Wi-Fi is obviously a more cost-effective choice. I believe some people will ask, I have never heard of Wi-Fi 5, why did Wi-Fi 6 suddenly appear? In fact, the name of the matter depends on the Wi-Fi Alliance. In the previous 5 generations, the name of the WiFi technology is Such:
The first generation 802.11a (1999), the second generation 802.11b (1999), the third generation 802.11g (2003), the fourth generation 802.11n (2009), the fifth generation 802.11ac (2014), the sixth generation 802.11ax (2019) is what Wi-Fi 6 is currently talking about.
Therefore, the Wi-Fi Alliance directly replaced the iterated protocol standard with Arabic numerals. This time the Wi-Fi Alliance may have figured it out. After all, mobile networks like 3G, 4G, and 5G are easy to distinguish. In the past, Wi-Fi -Fi technology naming is too troublesome. From the naming, we only need to know that the higher the number, the more advanced the technology. So what are the advantages of Wi-Fi 6?
1. The data transmission speed is faster. The theoretical speed of Wi-Fi 6 can reach 9.6Gbps, which is converted to a commonly used download speed of 1.2G/S, which is nearly 3 times faster than Wi-Fi 5. The OFDMA (orthogonal frequency division multiple access technologies) adopted by Wi-Fi 6 not only improves network efficiency but also effectively reduces the delay of upstream and downstream traffic.
2. With a larger capacity, Wi-Fi 6 continues the MU-MIMO (multi-user multiple inputs multiple output system) brought by WiFi 5, and Wi-Fi 6 supports the full version of MU-MIMO technology, which can support 8 at a time The terminal device transmits more data upstream/downstream, which is twice that of WiFi 5.
For example, the highway used to have only one lane. When entering, each car needs to line up in turn. Now it has not only eight lanes, but also two-way driving. Is it more efficient?
3. Low power consumption and more power-saving. Wi-Fi 6 supports the target wake-up time function, allowing the terminal device to enter the sleep state when not transmitting data, which can save up to 7 times the battery power consumption. In addition, it uses BSSColoring coloring technology, which allows multiple APs to run on the same channel at the same time, and intelligently manages multi-user simultaneous transmission in parallel, providing more users with greater WiFi capacity, high transmission efficiency, and more power-saving equipment.
4, anti-interference ability to strengthen, Wi-Fi 6 proposes a channel space multiplexing, when we use the Wi-Fi network at home, the more people are vulnerable to the problem of signal overlapping coverage, network interference, speed experience on It has become very poor. The technology of Wi-Fi 6 can theoretically solve the signal coverage problem of ordinary households and make the network experience better. In the past, the development of Wi-Fi technology has focused on the two dimensions of speed and range. However, Wi-Fi 6 not only includes improvements in speed and range, but also includes network intelligence, power consumption, and efficiency. It is an important upgrade for current user needs. When it comes to important promoters of Wi-Fi 6 and above technical advantages, Qualcomm has to be mentioned.spark global limited
02 Why do more and more mobile phones use Wi-Fi 6?
Users who are familiar with the mobile phone industry know that mobile phones with Qualcomm Snapdragon processors currently on the market account for a very large proportion, especially in flagship phones. The reason is very simple. One is because of the powerful comprehensive performance of Qualcomm’s Snapdragon processor, and the other is that Qualcomm has obvious technical advantages in the field of communications.
