With the rapid development and increasing popularity of 5g, the excellent characteristics of high speed, high reliability, ubiquitous network and low delay make Wi Fi no longer necessary in many times, and even the argument that Wi Fi can be stopped appears.
But on the other hand, Wi Fi is not stagnant. The latest Wi Fi 6 and Wi Fi 6e are also evolving along the same way as 5g. In particular, Qualcomm, the industry giant and the world's largest Wi Fi market share, is leading the way in Wi Fi 6 / 6e technology and solutions.
Recently, in collaboration with Xiaomi, Qualcomm held a special technology salon to talk about and demonstrate the Gigabit experience brought by Wi Fi 6.
Qualcomm's several related acquisitions are also very targeted. For example, after the acquisition of chuangruixun in 2011, the pace of promoting Wi Fi technology and products was significantly accelerated. The acquisition of ubicom in 2012 strengthened the network side processing capacity. The acquisition of wilocity in 2014 brought rich experience in 60GHz network side products. The acquisition of CSR in 2015 and a half enhanced the technical reserve and product portfolio in the Bluetooth field.
Wi Fi 6 has advanced features such as Gigabit upload rate, MU-MIMO multi-user multi input multi output, OFDMA multi-user access, 1024 QAM modulation and coding, TWT target wake-up time, BSS coloring to reduce neighborhood interference, 8x8 data stream, etc., which can better meet the current high-speed, multi device, low delay and stable connection requirements.
Wi Fi 6e extends the frequency band to 6GHz. The advantage is that it has rich spectrum resources up to 1.2Ghz. It carries seven non superimposed 160MHz bandwidth channels (only two in 5GHz band), and only runs Wi Fi 6 without interference from traditional devices. It can further improve throughput and reduce delay.
Of course, Wi Fi 6 in the 6GHz band is not an international standard, especially it has not been implemented in China, which still needs time.
It is estimated that by 2022, the annual shipment of Wi Fi 6 chips will exceed 1 billion, 56% of new terminals will support Wi Fi 6, and by 2024, Wi Fi 6 will become the mainstream standard.
For Wi Fi mobile connection, the main platform of Qualcomm is fastconnect seriesOf which6100 and 6200 in the early Xiaolong 855 EraIt supports the large-scale deployment of key features of Wi Fi 6, which is called Wi Fi 6 ready by Qualcomm, that is, it has not fully supported Wi Fi 6, but is ready.
6800 launched with Xiaolong 865 platform, fully support Wi Fi 6, some technologies even exceed the standard requirements, the downlink rate is up to 1.8gbps, and Bluetooth 5.2.
The latest 6700 and 6900 fully comply with Wi Fi 6e standard, and support 6GHz band, 4K QAM and 160MHz channel, especially the latest real-time dual Wi Fi 6.
At the same time, the coverage is doubled, and the delay is lower, the response is faster, and the transmission is smoother, which can easily achieve the whole house signal coverage.
At present, more than 100 snapdragon smart phones with the fastconnect 6900 solution have been released or under design.
On the network side, Qualcomm has two product lines that can cooperate with the fastconnect mobile connection system on the mobile terminal side. One is networking pro, a professional networking platform of Qualcomm, which released the 400, 600, 800 and 1200 series in August 2019 and 610, 810, 1210 and 1610 Series in May 2020.
The first or two digits of each model represent the number of data streams. For example, 600 / 610 has 6 streams, and so on.
The X10 series also supports Qualcomm's third class Wi Fi 6 technology, that is, it supports 2.4GHz, 5GHz and 6GHz bands at the same time, and uses the 6GHz band for backhaul (5GHz high frequency is used in open areas), so that the other two bands can achieve better coverage and will not conflict with each other.
Qualcomm believes that tri band is the future direction of Wi Fi 6, and only when it is combined with Wi Fi mesh network, can the whole house be truly covered.
Another network side product line is immersive home, which was born in November 2020. It includes 214 and 216 models of dual band Wi Fi 6 and 314 and 316 models of Triple Band Wi Fi 6 / 6e.
In general, Qualcomm has a complete end-to-end product portfolio on Wi Fi 6 / 6e, a fast connection system on the device side, a professional networking platform and an immersive home networking platform on the network side. Both OFDMA performance and MU-MIMO performance are at the leading level in the industry, and a strong CPU provides support for the development of more applications.
As a loyal partner of Qualcomm, Xiaomi has released mobile phones equipped with fast mobile connection system, a number of router products equipped with Qualcomm professional networking platform and immersive home networking platform, among which router plays a very important role in the whole Xiaomi ecosystem.
Last year, Xiaomi launched its first flagship routing ax3600, quad core A53 and dual core network acceleration engine, which is equipped with the professional networking platform of Qualcomm 600. It supports access to 248 devices and has won many awards.
After that, we saw Xiaomi ax1800 of 400 professional networking platform, redmi ax5600 of professional networking platform, redmi ax6216 of immersive home networking platform, Xiaomi ax60001210 of professional networking platform and Xiaomi ax9000 of professional networking platform.
Ax9000 has four core A53 CPU and dual core NPU, which are manufactured by 14nm processNPU (network acceleration engine) has a computing power of more than 20000 DMIPS and is specially responsible for handling network traffic
In the venue, Qualcomm and Xiaomi also put Wi Fi 6 / 6e full scene application devices, which can experienceThe ultimate transmission speed of Wi Fi 6 / 6e (download easily approaching 1Gbps), four channel dual band real-time concurrency (smooth game without jamming)And so on, you can also feel the smart home of Xiaomi aiot.
