On January 3, 2020, Lu Weibing, Xiaomi's president of China, published a micro blog, saying that his new mobile phone supports 5g multilink, can realize three networks concurrent, and is equipped with a video tutorial to enable this function. Many users are excited by this move, but in the eyes of ColorOS users, this is not the dual Wi-Fi that has been used for a long time. Moreover, it has been supported in part since the era of ColorOS 6, and ColorOS 7 has been carried forward.

It's not a dream to use the right network speed multiplication

Coloros makes use of the DBS / DBDC chip technology support of oppo Reno series to enable the mobile phone to connect two Wi Fi hotspots to the Internet at the same time. Note that it does not only support dual frequency Wi Fi, but supports connecting two Wi Fi at the same time. It is different from the traditional concept of supporting 2.4GHz and 5GHz.

In order to let you more intuitive understanding of the benefits of dual Wi Fi, the author did an experiment in person. First, limit the download speed of the mobile phone to 1000KB / s in the router, and then download "King glory" in the software store. You can see that the maximum download peak at this time is about 1MB / s, which is in line with our speed limit.

But soon we can see that there is a change in the Wi Fi icon at the top of the screen. A small Wi Fi icon appears on the left side of the large Wi Fi icon. At the same time, the download speed of "King glory" has also soared to 2.4m/s. When I return to the Wi Fi setting interface to check, it is sure that the system has automatically turned on the dual Wi Fi function, which is the reason why the download speed has soared.

In the router management interface, you can clearly see that the mobile phone is connected to the 2.4GHz and 5GHz Wi Fi transmitted by the router. Therefore, coloros 7 uses two channels to access the Internet in such a way to achieve double network speed and seamless network switching.

How to turn on dual Wi Fi in coloros 7

Since dual Wi Fi is so easy to use, how can coloros 7 be turned on? We can turn on the function by turning on settings WLAN intelligent network acceleration dual Wi Fi network acceleration. When it is turned on by default, once the system detects that the current network environment is poor or that the user is in a download scenario, it will automatically turn on dual Wi Fi acceleration. From the list of this interface, you can see that the applications supported by dual Wi Fi of coloros 7 are basically comprehensive. Mainstream browsers, video apps and shopping apps are all in the supported list.

summary

In some application scenarios, you will find that dual Wi Fi is a very easy-to-use function, and the introduction of coloros and the late arrival of Xiaomi can prove the importance of this function. I believe that in the future, there will be more systems with dual Wi Fi functions, which will bring better experience to users. If you are a user who supports dual Wi Fi handsets, you may as well turn on this function to make the network connection faster and more stable.
