2020 is almost over, have you used Wi-Fi 6?

Why is it a 1000 Mbps network, but the actual speed is only 100 Mbps? Don't rush to complain to the operator, the problem may be on your Wi-Fi 5 router.

Faced with increasing demand for data transmission, the Wi-Fi 5 standard has become outdated. The next-generation Wi-Fi 6 standard that can provide greater bandwidth and carry more devices is the choice for Gigabit networks.

However, for the new Wi-Fi 6 standard, it is estimated that some people will subconsciously think that the router that wants to replace Wi-Fi 6 "should be very expensive."

In fact, the cost of updating routers is not high at all. After a year of development, the Wi-Fi 6 market has matured. On shopping platforms such as JD.com, you can see that the most popular Wi-Fi 6 routers have reached the price range of 200-300 yuan, replacing the mainstream Wi-Fi a year ago. -Fi 5 products.

In other words, now is the best time to update routers.

Why switch to Wi-Fi 6?

You may remember when you last changed your phone, but you may not remember when you last updated your router.

As the "last mile" connecting people to the network, routers play the most important role, but they are always ignored. After the trend of working from home, the importance of home network began to receive more attention.

Do you find the following pictures very familiar:

  • Slideshow stuttering in the video conference with colleagues in the study
  • Walked from the living room back to the room to prepare for a strong kill under the tower but found that he could not move
  • The three characters “buffering'' appear at the critical moment of the actor's escape

Please put down the phone number you are preparing to complain to the operator. The problem may appear on the Wi-Fi router you bought 5 years ago.

People always feel that their routers used to be well-used in the past, but now they suddenly get stuck, but they don't realize that their network environment has changed drastically.

Five years ago, the Internet was still in the era of graphic information. 720P video is already the highest quality of the website; now it is the era of short videos, and 4K ultra-high resolution videos are becoming more and more common under the promotion of mainstream video platforms. , People’s demand for video sharing is unprecedented. In addition, the refresh of popular games for higher picture quality also puts forward higher requirements on the network.

With the development of IoT, everything needs to be connected to Wi-Fi. From a small sensor to a smart air conditioner and smart washing machine, it needs to be connected to Wi-Fi. In order to form a smart home system, there may be more than a dozen. Each device needs to be connected to the wireless network.

Once your Wi-Fi was just a servant serving your mobile phone and tablet personally, now it has to become a running hall that needs to take care of an entire restaurant, not to mention that your mobile phone and tablet are more demanding on the Internet. So is it not difficult to understand why Wi-Fi becomes a card?

The explosive development of information has put forward higher requirements for network bandwidth. The increase in home electronic devices and the popularity of smart home appliances also require routers to have stronger endurance. The emergence of Wi-Fi 6 is precisely to meet this high bandwidth. Multi-device network requirements.

A good partner for Wi-Fi 6

With the joint efforts of mobile phone manufacturers and router manufacturers, the rapid popularity of Wi-Fi 6 has made this network revolution extremely "approachable".

To experience this Wi-Fi revolution freely, a device that supports Wi-Fi 6 and a high-performance router are essential. As the most common wireless device in daily life, mobile phones are naturally the best entrance to experience Wi-Fi 6.

Xiaomi has always been a pioneer in advancing Wi-Fi 6. The Redmi K30 Pro mobile phone launched by its Redmi brand at the beginning of the year is still one of the most cost-effective Qualcomm Snapdragon 865 phones.

At the same time, Redmi recently launched the newly launched Redmi AX6 router equipped with Qualcomm Networking Pro 600 series platform and 5GHz 4×4 antenna, bringing the entry barrier of Wi-Fi 6 to 399 yuan, making the new generation of Internet experience no longer unattainable.

The Qualcomm Snapdragon 865 chip on the K30 Pro supports 8×8 data streams in the 5GHz support frequency band, dual-band 1024-QAM debugging, and AX6 routers can easily play the strength of the gigabit network, and the network speed is improved compared to the old standard router Up to 40%, network delay can be reduced by 30%.

Only high-speed and low-latency network conditions can meet people's entertainment needs for ultra-high-definition video and refreshing gaming experience.

Not only that, with the support of the Wi-Fi 6 standard, AX6 can support 4 times the number of device connections. Whether it is support for IoT or a public environment where a large number of devices are connected, Wi-Fi 6 routers are more comfortable

This is not only due to the greater bandwidth advantage of Wi-Fi 6, but also the excellent power consumption performance of the AX6 router. Users who have used the old generation router products should know that when the router is used for a long time, it will always get hot, which will greatly reduce its transmission performance.

The Qualcomm solution adopted by AX6 is a good balance between power consumption and performance. For example, TWT (target wake-up time) is used to coordinate mobile terminals. Even if the workload is heavy, the surface temperature is only around 40 degrees Celsius, which will not affect performance at all. Play.

The problem of network speed is solved, what about the problem of coverage? After all, everyone’s home is not a large playground with unobstructed views. Whether it is the obstruction of the load-bearing wall or the limitation of the transmission distance, it will cause signal blind spots during use.

The most typical example is that when you go to the toilet, you can't happily chase drama because of the extremely slow internet speed. At present, there are various solutions to solve the problem of poor network signal, and among them, the most mentioned word is Mesh.

"Your signal is not good? Mesh! One Mesh is not enough, only two. I used my neighbors and said yes."

The advantage of Mesh construction is its convenience, and it is most suitable for users who are novice users or large-sized users who are afraid of trouble.

Mesh routers use more to win than less, turning a traditional network signal broadcast center into a multicast, where the signal is not easy to install. Moreover, when moving back and forth in the range of several Mesh routers, the switching of the network is seamless, which means that the movie-watching experience that was abruptly stopped because of stomach pain has become a thing of the past.

It is also very simple to build a Wi-Fi 6 Mesh network. Just place a Mesh router where you need to build the network, and then connect them through the App.

Like Lingshi's Velop MX10600-16000M router and Orbi RBK752 AX8400M are good choices for building Wi-Fi 6 Mesh networks. The former is equipped with Qualcomm Networking Pro 1200 series platform, and the latter is equipped with Qualcomm Networking Pro 800 series platform.

In addition to routers, all new electronic products now support Wi-Fi 6. Including some of the latest tablets and laptops, all support the Wi-Fi 6 wireless standard.

On mobile phones, according to previous data, there are already more than 70 mobile phones equipped with the Snapdragon mobile platform that support the Wi-Fi 6 standard through the FastConnect 6800 mobile connection system, such as OPPO Find X2 series, Xiaomi 10 series, vivo NEX 3S and X50 Pro+ and more.

Qualcomm expects to ship 1 billion chips equipped with Wi-Fi 6 solutions by 2025. It can be said that Wi-Fi 6 has been integrated into our lives.

Beyond 5G, what did Qualcomm do on Wi-Fi 6

It can be said that the extraordinary network experience is due to the hero behind the mobile phone and router-Qualcomm Wi-Fi 6 end-to-end solution.

According to Aifaner, Qualcomm has invested in R&D for more than ten years in the Wi-Fi field, and has shipped more than 4 billion Wi-Fi chips since 2015. This fully demonstrates Qualcomm’s leadership in the Wi-Fi field. .

The rapid popularization of Wi-Fi 6 this year is also inseparable from Qualcomm's efforts in terminal products. According to data released by Qualcomm earlier, more than 200 wireless routers equipped with Qualcomm solutions have been shipped or are under development.

"Stable" is one of the important keywords of Qualcomm's Wi-Fi 6 solution. It is not the whole goal of Wi-Fi 6 to make data run fast. It is the primary goal of network development to make data transfer stably and quickly.

Because the biggest feature of the Wi-Fi environment is mobile, in order to ensure the stability of the network in a complex working environment, Qualcomm combines its dual platform advantages on the mobile side and the router side to provide an "end-to-end" s solution.

The combination of Redmi K30 Pro equipped with Qualcomm Snapdragon 865 mobile platform and Redmi AX6 router can give full play to this "end-to-end" platform advantage.

With the FastConnect 6800 mobile connection system, K30 Pro enables the mobile phone to receive Wi-Fi signals in both 2.4GHz and 5GHz frequency bands at the same time. This means that the choice of how to use Wi-Fi frequency bands for the best experience can be up to the "demand-side" mobile phone.

This means that when your signal is poor, the phone will automatically use the 2.4GHz network for transmission, so that you will not be left behind in the surfing team, and when your signal condition is good, the phone will run to the faster 5GHz. The frequency band makes you one step faster.

This kind of "end-to-end" seamless switching is completely insensitive, because the mobile phone receives two signals at the same time, which achieves stability and speed without any cost of use.

On the router side of Redmi AX6, Qualcomm has done much more than you think. In order to allow each user connected to the router to receive high-priority services, the router will share complete resources to multiple devices at the same time. This technology is MU-MIMO.

This is like when running in a playground, each device was originally divided into its own corresponding track, and the width of the track is very narrow on the head of each device, which limits the transmission of large amounts of data.

And if this width restriction is lifted, each device can run on the entire large track, and the amount of data will not be restricted.

The most intuitive embodiment is that each user's speed and timeliness will bring improvements.

When multiple users are transmitting, AX6 uses the OFDMA technology of the Qualcomm platform to make data transmission no longer a user-by-user queuing service, but rather like packaging each user's transmission data together for transmission.

This means that even if you are playing "King of Glory", the sister who has the latest episode of "Summer of the Band" in the buffer next to you will no longer interfere with your delay, because your data transmissions are all at the same time. .

The application of OFDMA has improved the utilization of resources. The scenario of "one person downloads the film and the entire dormitory is disconnected" is destined to become a thing of the past, which not only greatly improves the personal experience, but also eases the tension in the dormitory or family due to network competition Interpersonal relationship.

Real-time dual-band Wi-Fi, uplink MU-MIMO, OFDMA transmission and other black technologies are inseparable from Qualcomm's research and development of "end-to-end" Wi-Fi 6 technology. If before that, you thought that Qualcomm only represented an advanced mobile phone platform, now you should realize that there are Qualcomm solutions behind the construction of the digital world.

Just as people are constantly pursuing the extreme speed of automobiles, so are people's endless pursuit of network speed. Wi-Fi 6 makes future technologies such as the Internet of Things, driverless, VR or AR become reality one by one, and this reality from the future is within your reach now.

Higher and higher
