Some time ago, Wi Fi 6 was ignited. Xiaomi 10, starting at 3999, listed it as a hard core configuration, and specially released a Wi Fi 6 router for use. Huawei is also unwilling to show weakness. It marked a big plus on its Wi Fi 6, showing that you have my excellent attitude.

Mobile phone companies are very excited, but consumers are a little confused. They have never heard of Wi Fi 2345. Why is it 6. In short, Wi Fi promotion is finally enlightened. In the past, the names of Wi Fi series are engineer oriented, which are 802.11 a / B / g / N / AC generation 5 respectively, which is hard to understand.

In contrast, the mobile communication industry has simplified and publicized the awkward words such as GSM, WCDMA and LTE to 2G, 3G and 4G. This naming method of understanding and buying as soon as you understand is loved by the industry.

Therefore, in 2019, the Wi Fi alliance decided to name the new 802.11 ax standard Wi Fi 6, and recognized the early technology as generation 1-5. In addition, it also registered an eye-catching trademark and printed it on the router package, so that consumers can see it clearly.

After all, the aroma of wine is also afraid of the depth of the alley. No matter how powerful the technology is, it also pays attention to a good understanding and easy dissemination.

So what’s the use of Wi Fi 6? In short, the effect is 666. Let’s touch it.

Part1. No matter how many mobile phones, you are not afraid to rob the Internet

The first feature of wi-fi6 is that you don’t have to worry about grabbing the Internet.

The upper limit of network throughput and rate has been greatly improved, almost 1.5 times that of the previous generation, but this is not the focus.

The point is that wi-fi6 is not only fast, but also allows everyone to be fast together.

One is through OFDMA technology, no matter how many links, you can also enjoy high network speed.

In daily life, when several mobile phones are connected to the same Wi Fi, they often encounter network grabbing war. As long as someone opens HD video, another player who plays King glory will immediately become ppt.

This happens because the traditional Wi Fi technology only allows the router to exchange data with one device at a time. If the next device wants to connect to the network, it has to wait for the next communication cycle.

As a result, on the one hand, the utilization rate of communication cycle is low. A device connected to the network once takes up a whole communication cycle. It is found that it only brushes a few microblog pictures.

On the other hand, other devices have to queue up to surf the Internet. If they fail to catch up with the queue for several consecutive communication cycles, they can only look at the full grid signal in their hands and sigh.

Using OFDMA technology, you can communicate with multiple devices at the same time in a communication cycle, which improves the communication efficiency and eliminates the need for queuing.

In addition, MU-MIMO technology also solves the problem of multi device network.

In the traditional Wi Fi technology, each connected device must be divided into a certain bandwidth. There are more connected devices, and the large water pipe of the fire hydrant must also be divided into faucets. However, Wi Fi 6 relies on MU-MIMO technology. When 8 devices are connected to the intranet, the bandwidth will not be divided. How fast the network should be.

Therefore, Wi Fi 6 can not only greatly improve the upper limit of network speed, but also greatly improve the utilization efficiency of the network. It really plays the name of the next generation communication technology.

Part2. With 5g, it’s really fragrant

Many features of Wi Fi 6 can be said to form a natural partner with 5g.

5g technology is fast, but it also has a disadvantage: in order to pursue strong communication ability, 5g adopts high signal frequency, and the higher the signal frequency, the shorter the transmission distance and the worse the penetration performance, which means that 5g indoor signal may not be satisfactory.

The Wi Fi 6 covering the 2.4GHz band with stronger through wall capability can successfully make up for this short board.

Another point is the economic factor. The initial tariff of 5g is still a large expense. After all, operators paid a lot of money when building 5g base stations, and they are still counting on selling traffic packages to get back the cost.

In this way, users will still choose the cost per bit, that is, 1 / 30 of 5g Wi Fi home traffic.

However, the network speed of the mobile phone has been getting faster because of 5g. It is obviously unacceptable if the anti network speed is slower at home. Spending some money to upgrade Wi Fi 6 has become a natural choice.

In addition, the 5g era is known as the era of the Internet of things. All kinds of homes want to connect to the Internet and label themselves with smart labels. If you still use the traditional old Wi Fi technology to grab the network and divide the network, the intelligence of your home will increase, and the brushing of short videos will slow down. This problem will eventually be solved by Wi Fi 6, which is perfectly competent for multi device Internet access.

However, since Wi Fi 6 with so many advantages has been launched in 2019 and has long been supported on iPhone 11, why did it become popular at the beginning of this year?

The reason is simple, price and ecology

A random search of some brand Wi Fi 6 routers basically starts with thousands, and two or three thousand are normal. After all, there are several more rounds of optical antennas, and with the new chip modules, the layout of a bit high-end routers is understandable.

How awesome is WiFi 6

In addition to the main low-cost tp link, it started more than thousands of yuan

But how many families will spend the price of a medium equipped mobile phone to buy a high-end router?

Moreover, to play a Wi Fi 6 router, you also need a corresponding Wi Fi 6 mobile phone and higher bandwidth. The external ecology is immature and you can buy it for nothing.

Pushing Wi Fi 6, Xiaomi obviously took this problem into account, so it launched 599 router, which can be regarded as providing a set of market-oriented scheme for the popularization of Wi Fi 6. Huawei is undoubtedly ready to directly prepare its own router equipment.

Therefore, the price problem is likely to be solved with the introduction of popular models by head manufacturers and low cost sharing.

The ecological problem of support will be gradually eliminated as the flagship machine supports Wi Fi 6 function one after another.

Therefore, the scenario that wi-fi6 takes off with 5g and the router shares the same base station is likely to be staged synchronously.

Part 3. IOT detent link

Behind every change in standards is the reorganization of the industrial chain. Although there are many antennas on the surface of wi-fi6 router, the intrinsic value is improved by Wi Fi chip and heel module.

Naturally, the main chips are foreign communication giants Broadcom and Qualcomm. For example, Xiaomi’s ax3600 router uses Qualcomm’s ipq8071a chip, while most of the best-selling ASUS Wi Fi 6 routers in JD are Wi Fi chips provided by Broadcom.

However, this situation is still different from the Wi Fi 5 era. After launching the LingXiao Series Router Wi Fi chip in 2019, Huawei gradually took advantage of its advantages in communication product terminals to gain a foothold. This time, in the field of Wi Fi 5 chip, Huawei’s router used the self-produced Lingxiao 650 series wi fi chip.

The transfer of the development right of router chips will undoubtedly extend to the battle for the Internet of things. After all, if your IOT devices want to access the network, you have to go through the router channel. Whose router can access a large number of devices and experience the whole better, it will naturally gain the upper hand.

For example, Xiaomi’s router can add alot antenna when integrating the router to realize that Xiaomi devices are close to the automatic connection, but the core function of chip scheduling still needs to rely on Qualcomm.

However, Huawei claims that because it has done end-to-end chip research, it also has higher degrees of freedom in the core functions of its Wi Fi 6 + chip, such as judging the priority of networking services, accelerating and connecting to device identification. In this sense, in the so-called “1 + 8 + n” strategy at Huawei’s press conference, the core of “n” connection lies in its own Wi Fi 6 chip.

Therefore, the tepid Wi Fi business in the past may be improved under the promotion of the 6th generation standard. After all, technology, capital, policy, IOT and the Internet of things have been calling for some time, so we have to make some solid progress.
