I don’t even understand WiFi 6, what are WiFi 6E and WiFi 6 enhanced?

Recently, my colleague Mr. Musi wanted to change the router, so he asked me if Xiaomi’s new AX6000 router is WiFi 6E, and if it needs 888 to enjoy the highest speed.

Obviously, he hasn't studied this aspect recently. He is a bit dizzy about these terms, and he is not sure what kind of hardware support is needed.

Then talk about these things today.

After the concept of WiFi 6 began to be popularized in the new routers, the emergence of new terms such as WiFi 6 enhanced version and WiFi 6E made the public who had finally digested the new technical terms become more confused. What is the relationship between WiFi 6E and WiFi 6? Is WiFi 6E equal to WiFi 6 enhanced version?

Let’s talk about the WiFi 6 enhanced version. This WiFi 6 enhanced version is actually a new term proposed by Xiaomi. At the Xiaomi 11 conference on December 28 last year, in addition to launching the first Xiaomi 11 equipped with Snapdragon 888, it also launched the first time. Mi Router AX6000 with WiFi 6 enhanced version.

It's only half a year since the AX3600, which has been continuously praised, was launched. This time the WiFi 6 enhanced version was released, which makes people wonder what it is.

Xiaomi has promoted the WiFi 6 enhanced version as the new WiFi standard in 2021, in which three features are written in the posters, namely:

  • Support 4K QAM encoding
  • Support 160MHz bandwidth
  • The peak rate reaches 3.5Gbps

The core reason why Xiaomi calls this WiFi 6 enhanced version should be the first new feature, which is the support for 4K QAM encoding. This feature was originally not a new feature of the original WiFi 6. Through WiFi Alliance , we can see that the original WiFi 6 is 1024-QAM encoding.

So Xiaomi calls this WiFi 6 enhanced version, so where can we see support for the 4K-QAM standard? The answer is that there is no standardization, and even in the advancement of the WiFi 7 standard, 4K-QAM has not yet become a standardized technology.

It is precisely because of this that manufacturers have the opportunity to propose new terms. Whether it is the enhanced version of Xiaomi’s WiFi 6 or Huawei’s WiFi 6+, it is a new name created by the introduction of some technical specifications that exceed the WiFi 6 standard. Of course, Huawei is a self-developed chip used by an old communications factory, while Xiaomi uses It is Qualcomm's chip.

In fact, I can explain it again. 4K-QAM coding is currently only Qualcomm pushing. And WiFi 6 now has an extended standard called WiFi 6 (E stands for Extended). In the standard WiFi 6E, the most important feature is to support the 6GHz frequency band (5925-7125 MHz, a total of 1.2 GHz bandwidth). , Let the router incorporate a new frequency band into the use standard in addition to the current 2.4GHz and 5GHz.

However, in the WiFi 6E standard, 4K-QAM is still not mentioned. In fact, in the standard WiFi 6E, the most important feature is to support the 6GHz frequency band (5925-7125 MHz, a total of 1.2 GHz bandwidth). Let the router include a new frequency band beyond the current 2.4GHz and 5GHz into the use standard. ,

However, in fact, no country has determined how to use the 6GHz band, and it has not been opened to civilian use. It is still in the test of promoting various services. Therefore, there will be no routers that truly support 6GHz on sale recently, that is, it cannot be claimed. I support WiFi 6E.

Talking about the technical standards for a long time, because WiFi technology is still evolving and chip manufacturers are constantly launching products with higher technical specifications, it is actually not easy to clarify all WiFi 6 derivative standards and terms at this stage. For mass consumers, what is really important is what can be used.

Take Xiaomi AX6000 as an example. It claims to be WiFi 6 or WiFi 6 enhanced version, even if it is called WiFi 8, what consumers can get is the most important thing.

The biggest bright spot is naturally the peak speed, but it should be noted that the WAN port of the AX6000 is 2.5Gbps, and the remaining 3 LAN ports share 1Gbps.

As for how the 6000Mps rate on the leaflet came from, it is actually a theoretical value. The theoretical data in the 5G frequency band under 4×4 MIMO 160MHz is 4800Mps, plus 2.4GHz 2×2 MIMO, theoretically 574Mbps, plus The independent AIoT antenna is also 574Mbps, totaling 6000Mps in total, but the upper limit of timing is much lower than this number.

As for how the 3.5Gbps number on the promotional page came from, in fact, under 4K-QAM, the AX6000 supports up to 2×2 MIMO 160MHz, which is 1200Mbps x2x1.2=2880Mbps, plus 2.4GHz concurrent 574Mnps, a total of 2880Mbps+574Mbos =3456Mbps, rounded to 3.5GHz.

In addition, if you want to experience the high speed brought by 4K-QAM and 2×2 MIMO 160MHz at the same time, you also need a Snapdragon 888 mobile phone. It is precisely because 4K-QAM is a technology that Qualcomm is pushing, so it is currently Only Snapdragon 888 mobile phones can support.

Simply put, in order to experience the enhanced version of WiF i6, in addition to the AX6000 router, you also need a mobile phone with Snapdragon 888, which can be your own Mi 11, or iQOO7 or Samsung’s latest S21 series. Both can support the 20% rate increase brought by 4K-QAM.

If you want to combine this set, a 599 yuan router is not expensive, but Snapdragon 888 phones are not cheap now. Of course, if you are not a Xiaomi user, but are interested in WiFi 6+, then let's talk about Huawei.

The AX3 router that Huawei launched earlier claims to support WiFi 6+. In fact, Huawei’s WiFi 6+ refers to the 160MHz bandwidth, but it has been released for nearly a year. The advertised Lingxiao WiFi 6+ chip at the time allowed the P40 series of mobile phones to reach 2976Mbps under 2.4GHz and 5GHz dual WiFi concurrently, which is actually 2400Mbps under 2×2 MIMO 160MHz + 576Mbps under 2.4G, a total of 2976Mpbs.

To sum up, what we are looking at now is not the terms WiFi 6+, WiFi 6 enhanced version, or even WiFi 6E. It's the limitations of the product itself and how much it will cost consumers to achieve this experience.

For example, the AX6000's 2.5Gbps adaptive network can only divide the rate into wireless, and wired devices will still be necked by the 1Gbps network speed card. Except for mobile phone WiFi use, then the most remaining use is to wirelessly connect to NAS devices, but considering wireless For the frequency of use of NAS, if you want to make full use of the 2.5G port, you might have to connect a switch of several hundred yuan.

In addition, mobile phones also need new models to support the latest features, such as iQOO7 and Mi 11, which currently cost about 3800-4000 yuan, otherwise the so-called "WiFi 6 enhanced version" would not be experienced.

In addition, many people have never noticed that the network cable specifications are actually different. For example, the common super five network cables are mostly used for 100M networks. When they are above Gigabit, they will not be able to eat. You need to replace the six types of network cables.

Find out these things, and then according to your actual needs and the characteristics of the router, you can choose the most suitable product.

As for going back to the beginning, why Ms. Musi wanted to change the router is actually not because he is interested in WiFi 6, but because he needs a game accelerator plug-in built in the router, and considering whether to buy a new one or not, that’s why he considered AX6000.

Well, I see that for these gamers, the unused high speed is actually not as useful as the stable speed and built-in plug-in support.
