Shulou(Shulou.com)11/24 Report--

With the popularity of 5G mobile phones, it is believed that most consumers have already felt the experience of high-speed, low-latency mobile Internet connection. To put it simply, "if you use it, you can't go back to it." however, the use of 5G is usually outdoors, and it is a bit difficult to use 5G when you have Wi-Fi at home. However, can the Wi-Fi at home have the experience of ultra-high speed and very low latency like 5G? The answer is yes, but only if you equip your home with Wi-Fi 6.

Speaking of Wi-Fi 6, I believe we are no stranger to it. According to Deloitte's global forecast, shipments of Wi-Fi 6 devices will exceed 5G devices in 2022, to at least 2.5 billion units, compared with about 1.5 billion units in 2022. It can be seen that Wi-Fi 6 is of great significance for future wireless connections.

However, there are also some problems in the popularity of Wi-Fi 6. I believe many partners will find that their mobile phones and routers at home support Wi-Fi 6, but why do too many people still have delays and slow network speed when using the network every day, and there is still a dead corner of signal coverage. Am I using fake Wi-Fi 6?

No, your Wi-Fi 6 may not be fake, it's just "dissatisfied with blood". It is quite common that there are still all kinds of problems in the actual experience of Wi-Fi 6, which shows that manufacturers still have a lot of work to do in order for the public to have a high-quality Wi-Fi 6 experience. Especially in the details of the technical need to constantly upgrade iterations.

So, what does the "bloody" Wi-Fi 6 look like? Here happens to be an example of Qualcomm's 2 × 2 Wi-Fi 6.

2 × 2 Wi-Fi 6, the advantage is more than we thought to see the above term, some friends may feel confused, what is 2 × 2 Wi-Fi 6?

In fact, to find out what is 2 × 2 Wi-Fi 6, the most important thing is to understand what is 2 × 2 Wi-Fi.

1. What is 2 × 2 Wi-Fi? We know that for Wi-Fi communication, mobile phones need antennas to receive and transmit wireless signals, in which received signals (input) and transmitted signals (output) need to use different antennas. But in traditional mobile phones, one antenna is used for receiving and transmitting, that is, 1 × 1 Wi-Fi, or one-way Wi-Fi.

With the development of the Internet, people use more and more Wi-Fi application scenarios, such as ultra-clear video, online mobile games and so on have high requirements for Wi-Fi data throughput and delay. 1 × 1 is gradually unable to meet the demand, and there are often cases of weak signal, delay and stutter. So there is 2 × 2 Wi-Fi.

2 × 2 Wi-Fi is two-way Wi-Fi, as the name implies, it supports two Wi-Fi antennas to achieve double sending and receiving, receiving and transmitting at the same time.

To take an intuitive example, 1 × 1 Wi-Fi is like a two-way single lane, and 2 × 2 Wi-Fi is like a two-way two-way lane. obviously, two-way two-way lanes can hold a larger amount of data and are less prone to congestion or accidents. 2 × 2 Wi-Fi is to improve the Wi-Fi experience in such a simple and rough way.

2 × 2 Wi-Fi often needs to cooperate with MU-MIMO technology. The full name of MU-MIMO is "Multi-User Multiple-Input Multiple-Output", that is, multi-user, multi-input and multi-output. In addition to the mobile side, the router side also needs to support this technology.

Routers that support MU-MIMO can transmit signals to multiple devices simultaneously, while the corresponding SU-MIMO can only transmit signals to one device at the same time.

For example, at some time when you are playing games on your mobile phone at home, while your family is watching videos, the SU-MIMO router can only transmit video data to your family first, and then transmit game data to you. Normally, the switching speed is very fast, so you can't feel it. But once the video data is very large at a certain time, the switching delay will affect your playing the game.

This is not the case with a router that supports MU-MIMO, which can transmit data to both your family and your phone without affecting each other, and there will be no delayed stutters.

Therefore, 2x2 Wi-Fi and MU-MIMO are a combination of high-capacity, low-latency, non-stuttering Wi-Fi experience.

2. Qualcomm 2x2 Wi-Fi 6, there are some differences. I believe you can understand what advantages Qualcomm's 2x2 Wi-Fi 6 will have. It combines the leading features of 2x2 Wi-Fi and Wi-Fi 6, and not only that, Qualcomm has added Buff to them.

Take Qualcomm's most advanced 2 × 2 Wi-Fi 6e technology as an example, its flagship FastConnect 6900 mobile connection system supports Wi-Fi 6e for uplink and uplink MU-MIMO, which can achieve the top Wi-Fi technology and features.

One of the major innovations of FastConnect 6900 is that it can achieve 2 × 2 × 2 × 2 dual-band concurrency based on real-time dual Wi-Fi 6 technology (that is, it supports 2-channel data stream transmission in both 2.4GHz and 5GHz / 6GHz bands). In addition, it supports 4K QAM in each frequency band, so it can increase the connection rate to 3.6Gbps.

The 4-channel dual-frequency concurrency of 2 × 2 × 2 × 2 can also bring wider coverage. Usually in the family environment, the limited coverage of Wi-Fi signal and relatively large interference are the main factors that affect the experience of Wi-Fi signal. On the other hand, the dual-frequency concurrency of 2 × 2 × 2 can take into account the advantages of wide 2.4GHz coverage and less 5GHz interference, which can increase the coverage by up to 2 times while maintaining high speed.

In addition, the dual-frequency concurrency of 2 × 2 and 2 × 2 can bring ultra-low latency and faster response speed, which can respond faster and transmit data more smoothly no matter playing games or watching video streams.

It can be said that this technology is equivalent to the addition of Buff on the basis of 2 × 2 Wi-Fi 6, and the effect is naturally outstanding.

Of course, Qualcomm FastConnect 6900 mobile connection system also has other features to enhance the experience, such as the 4K QAM modulation technology just mentioned is the industry's first advanced modulation technology, which can achieve a 20% improvement in throughput compared to the standard Wi-Fi6/6E, and further enhance the gaming experience and ultra-high definition stream transmission capability.

At the same time, the application of MU-MIMO and 160MHz bandwidth technology of 8 × 8 data flow detection mechanism also provides support for improving throughput and reducing network congestion, so that a single terminal in a multi-user scenario can get a higher rate.

Large capacity in the 6GHz band can provide faster, more stable and more responsive links, especially in crowded places.

As you can see, Qualcomm's 2x2 Wi-Fi 6 is not only far ahead of the past Wi-Fi 5 era, but also introduces more feature additions to the 2x2 Wi-Fi 6 we normally see. So how does it perform in actual usage scenarios?

Don't worry, at the Snapdragon Carnival held in Chengdu not long ago, Qualcomm gave us a demonstration of 2 × 2 Wi-Fi 6 comparing 2x2 Wi-Fi 5 in a simulated actual use scene.

For example, in the comparative test of network throughput, Qualcomm simulates the network environment of Wi-Fi 6 and Wi-Fi 5, and then uses 8 devices equipped with Qualcomm FastConnect mobile connection system to simulate multi-user and high load scenarios. During the test, one device was used to upload files about 1GB in the multi-user scenarios of Wi-Fi 5 and Wi-Fi 6, respectively.

You can see that the upload speed of the terminal in the Wi-Fi 6 environment is significantly higher than that in the Wi-Fi 5 environment. When the Wi-Fi 6 environment device has finished uploading files, the Wi-Fi 5 environment device upload progress has only reached 12%.

In terms of average transmission speed, Wi-Fi 6 environment devices can reach 23142.4 KB / s, while Wi-Fi 5 environment devices only have 739.6KB / s.

In terms of delay and stability, Qualcomm also uses eight mobile phones to simulate multi-user scenarios, including four main demonstration devices that simulate games, videos and other application scenarios that require high time delay. the other four devices carry out data transmission applications that require low delay.

From the test results, we can see that in the Wi-Fi 6 network environment, the average delay of the four main demonstration devices is only about 4ms, which can play games and videos normally, while the average delay in the Wi-Fi 5 network environment is about 270ms, and the game and video experience will be significantly affected.

Qualcomm also compares the actual application scenarios. When you use the main demonstration device to play online games, you can see the delay curve measured by the software. Under the Wi-Fi 6 environment, the curve has not exceeded the yellow line of 150ms delay. The average delay of Wi-Fi channel during the game is only 54ms, and the packet loss rate and high delay rate are both 0.00%. The network status is very stable.

In Wi-Fi 5 environment, the delay curve frequently exceeds the 150ms yellow line, the average delay of Wi-Fi channel reaches 111ms, the packet loss rate is 0.44%, the high delay rate reaches 19.56%, and the network state is unstable.

It can be seen that Qualcomm's 2x2 Wi-Fi 6 has completely withstood the test of the actual use scenario, with greater throughput, lower latency and higher stability, and is indeed significantly ahead of Wi-Fi 5 in experience. This is also the exclusive advantage of Qualcomm, which shows the leadership of Qualcomm Wi-Fi technology.

Perfect product matrix, so that more people can enjoy the excellent experience of Wi-Fi 6. The Qualcomm 2 × 2 Wi-Fi 6 we introduced earlier mainly takes their flagship product's FastConnect 6900 mobile connection system as an example, and we also see what the top Wi-Fi 6 experience looks like. However, most of them are carried in the flagship mobile phone terminals, in reality, not all consumers will buy flagship mobile phones. So users who buy mid-and high-end, entry-level models will not be able to have such an excellent Wi-Fi 6 experience?

Of course not. In fact, Qualcomm has also built a complete array of Qualcomm FastConnect products for the consumer market, covering mid-to-high-end and entry-level products. For example, they also have Qualcomm FastConnect 6700 mobile connection system, this product also has the industry's first 4K QAM modulation technology, and supports 2.4GHz, 5GHz, 6GHz three frequency bands, support 2x2 Wi-Fi 6, although it is not a flagship product, but the highest theoretical speed can also achieve 3Gbps, but also achieve ultra-low latency less than 3ms, the performance is equally excellent.

And the earlier Qualcomm FastConnect 6800 mobile connection system, which was once installed on the flagship platform, can now become a mid-range model of choice. This product also supports full Wi-Fi 6 features, as well as 8x8 data stream MU-MIMO technology and high-order modulation of 1K QAM supported by 2.4GHz and 5GHz, which can further enhance the Wi-Fi 6 user experience.

Further push forward, there is Qualcomm FastConnect 6200 mobile connection system that supports Wi-Fi 6 Ready, which also supports 2 × 2 antennas and downlink MU-MIMO (8 data streams), which can become a choice for more entry models.

In addition to the terminal-oriented Qualcomm FastConnect mobile connection system, Qualcomm also has corresponding and rich products on the AP side: Qualcomm Professional networking platform (Networking Pro) and Qualcomm immersive Home networking platform (Immersive Home) provide the industry with a rich portfolio of Wi-Fi6/6E products, together with the terminal-side Qualcomm FastConnect mobile connection system, thus forming a complete end-to-end technical advantage from router to mobile phone.

Among them, 400,600,800,400,400,800,400 in the name of Qualcomm professional networking platform corresponds to the number of streams (for example, 1200 corresponds to supporting 4-channel data streams, and so on). MU-MIMO is closely related to the number of streams, and the more streams, the more high-bandwidth devices supported.

After the launch of Wi-Fi 6e, Qualcomm took the lead in launching the second generation of Qualcomm 610,810, 1210 and 1610 professional networking platforms.

Qualcomm immersive home networking platform is another main line of Qualcomm on the routing side, which achieves high-density deployment and brings immersive home networking experience by supporting small, compact and energy-efficient designs.

As a result, with the blessing of the full-link Wi-Fi 6 solution covering the routing network side to the terminal side, Qualcomm can really bring us an excellent 2 × 2 Wi-Fi 6 network connection experience in one step, and at the same time help Wi-Fi 6 network to land more valuable application scenarios in this era of gigabit network and Internet of everything.

Conclusion seeing here, I believe my friends can already understand why my family is clearly Wi-Fi 6, but the experience has not improved much. If you encounter this problem, you can torture yourself: do I use 2 × 2 Wi-Fi 6? Is it full of blood? The potential and experience of Wi-Fi 6 is far beyond what we can feel through text introductions. Of course, you don't have to bother. Both mobile phones and routers can get the most leading experience by using products based on Qualcomm 2 × 2 Wi-Fi 6 solutions.

From the data of IDC's survey on the size of China's Wi-Fi 6 terminal market last year, we can see that the popularity of Wi-Fi 6 market size will be very fast and will almost completely replace Wi-Fi 5 devices by 2024. This growth is naturally gratifying, but when it comes to the detailed experience of Wi-Fi 6, we still have a long way to go. It is also hoped that solution providers like Qualcomm can make continuous efforts to enable everyone to experience Wi-Fi 6 with full potential faster and more widely.
