PChome mobile phone channel evaluation Recently, a number of excellent mobile phones have been launched in the mobile phone market. They have been updated in hardware specifications and their functions are more compatible with the 5G era. Better photo performance, more extreme fast charging support, and a more comprehensive Wi-Fi network experience have really improved the experience.

the support of Wi-Fi 6 network is widely supported by all flagship models, which obviously represents the advanced nature of this technology. Of course, in fact, Wi-Fi 6 was supported in the previous generation of products, but at that time, because the relevant standards of Wi-Fi 6 were not fully formulated, the previous generation of products could only experience some features of Wi-Fi 6.

if you want to experience the ultimate experience provided by Wi-Fi 6 network to the greatest extent, then you'd better choose the combination of Wi-Fi 6 mobile phone and Wi-Fi 6 router. Qualcomm, on the other hand, can provide extensive Wi-Fi 6 technology and product support in both aspects, and can provide "end-to-end" Wi-Fi 6 solutions from routers to mobile terminals.

Networking Pro platform: comprehensive coverage from high-end to entry

Qualcomm has built Qualcomm Networking Pro series platform on the router scheme, and the multi-category scheme has enough different performance, which has all-round support for Wi-Fi 6 routers. At present, Qualcomm Networking Pro 4/6/8/12 series platforms provide comprehensive support for Wi-Fi 6 technology, while the second generation Qualcomm Networking Pro 61/81/121/161 series platforms provide support for Wi-Fi 6E technology. In the current Wi-Fi 6 router in Qualcomm, from the entry-level product Redmi router AX5 adopting Qualcomm Networking Pro 4 series to ASUS RT-AX89X adopting Qualcomm Networking Pro 12 series, Linksys Velop MX 53-53m, etc., products with different positioning levels can be found in all price segments ranging from only 1 yuan to several thousand yuan. It can be said that the popularity of Wi-Fi 6 routers has been greatly accelerated due to the continuous help of brands like Qualcomm.

the actual needs of users for Wi-Fi 6 are not the same. both entry-level routers with a price of one or two hundred yuan and high-end routers with a price of several thousand yuan are in demand. therefore, only by meeting the needs of users at all levels can the technology of Wi-Fi 6 be truly popularized.

compared with the commonly used Wi-Fi 5 router, one of the most remarkable performance improvements of the Wi-Fi 6 router is the faster network speed. The price of Redmi router AX5 with Qualcomm solution is only 249 yuan, which is a Wi-Fi 6 router with outstanding cost performance.

the fast experience of actual combat with Wi-Fi 6 is only the foundation

Compared with the current Wi-Fi 5, the transmission speed of Wi-Fi 6 technology has been significantly improved. Even the entry-level Wi-Fi 6 router Redmi router AX5 is not comparable to the previous generation routers.

what we are discussing here is not the theoretical speed of the ideal state, but the actual speed that can be realized in the real environment. In fact, this depends on the actual situation at both ends of the communication. The current mobile phone can provide 2x2 MIMO support for Wi-Fi networks, and the current entry-level Wi-Fi 6 router with four antennas can also match this feature of the mobile phone.

with the support of 2x2 MIMO, a mobile phone can get a downlink rate of 12Mbps by connecting to the 5G band under a Wi-Fi 6 router, while a Wi-Fi 5 router or mobile phone can only get a downlink rate of 867Mbps. This transmission speed has a performance gap of nearly 3%, but in fact the gap is more obvious. This is due to the fact that network operators have provided gigabit fiber-optic broadband, and the network speed of Wi-Fi 6 router exceeds the network speed limit, so it can run at full network speed. However, the maximum speed of the Wi-Fi 5 router can't reach the upper limit of broadband, which means that the Wi-Fi 5 router is already a performance bottleneck in the usual home environment, and using it will cause unreasonable waste of our package fees.

of course, in the actual real network environment, the network speed may not reach the highest theoretical speed, especially in the multi-user connected network environment. MIMO technology has obviously improved the network congestion in multi-user connections. At the same time, the OFDMA technology introduced in Wi-Fi 6 can summarize the data of multiple terminals and send them in packages, which is more efficient than the frequent data stream sending in Wi-Fi 5. With the support of BSS Coloring, devices can distinguish the relationship between them, thus reducing the mutual interference between devices and increasing the network communication capability of each device. These technologies especially improve the stability and reliability of Wi-Fi network, which is also confirmed in our actual test. Wi-Fi 6 mobile phones are fully ahead in terms of overall network delay, maximum and minimum values. In fact, we can see from the actual data map that the Wi-Fi 6 network also fluctuates, but the fluctuation is controlled within an acceptable range, after all, it has not exceeded 1ms；; On the other hand, the model that only supports Wi-Fi 5, the delay increases sharply when there is fluctuation, directly exceeding 3ms, which is already an obvious delay that can produce somatosensory sensation.

We have also conducted a practical test here. In a network topology composed of Gigabit broadband, there are always more than a dozen devices connected to simulate the home use environment. At this time, we use a mobile phone with Qualcomm Wi-Fi 6 scheme to download the game. The download of Peace Elite with a capacity of 1.84GB takes 35 seconds, with an average download speed of nearly 54MB/s and a maximum download speed of over 7 MB/s. Considering that this is the speed in the actual network environment, the performance has been very good.

The target wake-up time function supported by Qualcomm Wi-Fi 6 technology can deeply manage the mobile terminal. If the mobile phone doesn't use the Wi-Fi network for a long time, the router will send an instruction to the mobile phone to temporarily turn off the Wi-Fi module to save power, which can improve the battery life performance of the mobile phone and greatly save the power consumption of the mobile phone for certain scenes (such as sleeping at night). Here, we used a mobile phone that supports Wi-Fi 6 technology to test. The power consumption of the 15-hour Wi-Fi 6 environment is only 6%. Obviously, Wi-Fi 6 technology has also significantly improved the battery life of the mobile phone.

Redmi router AX5, an entry-level Wi-Fi 6 router, is generally enough for ordinary home environments. But I believe many users will also have higher demand. Higher-end products can provide more powerful Wi-Fi experience, such as supporting more spatial streams and having stronger performance in multi-device connection.

Qualcomm's end-to-end experience will be upgraded again

Faced with a wealth of Wi-Fi 6 routers and mobile phone products, the excellent experience of Wi-Fi 6 is already waving to us, and to get the most extreme Wi-Fi network experience, Qualcomm's plan is the first one. This is because the Wi-Fi 6 routers originated from the Qualcomm scheme in the market are rich in categories and easy to choose. They have end-to-end technical advantages compared with the huge Qualcomm scheme 5G mobile phone. The all-Qualcomm scheme of AP and mobile terminal can achieve the most extreme technical support, and some technologies can only be realized under the end-to-end connection of Qualcomm at present.

For example, the uplink MIMO support can be supported by Qualcomm's end-to-end connection, and the uplink MIMO support can further enhance the communication efficiency between the mobile phone and the router and maintain the stability of use. For scenes that need upload stability, such as live video, uplink MU-MIMO technology can significantly increase the network speed and stability.

Real-time dual Wi-Fi 6(2x2+2x2 dual-frequency concurrent) technology and comprehensive 124-QAM modulation mode are the other two advantages of Qualcomm's end-to-end experience. Real-time dual Wi-Fi 6 technology allows mobile phones to connect two frequency bands at the same time, and each frequency band supports two data streams for transmission, and 2x2 MIMO communication can be carried out simultaneously in both the 5GHz band and the 2.4GHz band, so the network stability is extremely stable.

comprehensive 124-QAM modulation is a key technology to improve network speed. At present, in the 5G band of Wi-Fi 6, the 124-QAM modulation mode has been fully popularized. Under the 2x2 connection mode, the speed can reach 12Mbps. For a top router like ASUS RT-AX89X, the theoretical speed can reach 48Mbps with the support of 8x8 MU-MIMO.

in order to enhance the signal coverage in the 2.4GHz band, the Qualcomm scheme also supports the 124-QAM modulation mode, which can increase the maximum network speed in the 2.4GHz band, so that we will not have a big experience gap with the 5GHz band when using this band. It should be noted that the 124-QAM modulation mode in the 2.4GHz band is not supported by all brand schemes at present, and the speed of using this band will be affected in some routers that only provide 256-QAM modulation.

at the end

there is no doubt that the experience of Wi-Fi 6 network is far beyond that of Wi-Fi 5. For consumers at the mass level, it is the general trend to upgrade to Wi-Fi 6 as soon as possible. On the one hand, the proportion of all kinds of big data stream applications is getting higher and higher. For example, the popular video applications need Wi-Fi 6 network to provide reliable network connection.

Wi-Fi 6 routers and mobile phone products supporting Wi-Fi 6 are also abundant, which further accelerates the popularization of Wi-Fi 6 networks. At present, the products at the router level are very rich. From the perspective of Qualcomm's scheme alone, the products ranging from 1-yuan entry-level products to thousands of high-end e-sports products have been widely covered, and consumers are worried that they can't buy a suitable router.

Wi-Fi 6 support for mobile terminals has also spread rapidly, and mobile phones using Qualcomm Snapdragon 865 mobile platform have fully covered Wi-Fi 6 technical support. Qualcomm Snapdragon 855 model and Snapdragon 765/765G model also have the support of Wi-Fi 6 Ready, and they have the key technical support of Wi-Fi 6 such as 8x8 MIMO/ target wake-up time /WPA3 encryption, which is obviously better than Wi-Fi 5 in experience.

At present, Wi-Fi 6 technology has been completely popularized in flagship mobile phones, and it will sink rapidly in the future. Now, users are advised to consider whether to support this function when purchasing mobile phones. Wi-Fi 6, like 5G, is the inevitable road of the future. Qualcomm, which has a broad market and top technical support in both mobile phone terminals and routers, is naturally our first choice. After all, its advanced technology and end-to-end support scheme are the most reassuring and worry-free.
