Where is the WiFi 6 technology?

To give a few simple examples, in 2005, Qualcomm launched its first MIMO chip; in 2006, it launched its first mobile Wi-Fi solution; it has developed to the current Wi-Fi 6, and Qualcomm has created many Wi-Fi fields. An “industry first”. According to official data, since 2015, Qualcomm has shipped more than 4 billion Wi-Fi chips, which is quite an amazing number. Qualcomm’s Wi-Fi 6 technology in mobile terminals is one of the most concerning points for consumers. Nowadays, everyone is inseparable from mobile phones. Faster, more stable, and safer networks are the pain points of modern people’s network needs. Based on these problems, Qualcomm’s FastConnect 6800 subsystem was unveiled with the launch of the Snapdragon 865 mobile platform. The FastConnect 6800 subsystem not only integrates Wi-Fi 6 function points, but also more technological innovations.

FastConnect 6800 can be said to be the killer of Qualcomm in Wi-Fi 6 technology. It has new technologies that are different from common Wi-Fi 6 solutions, such as 2×2+2×2 dual-band concurrency and 8×8 data stream detection. 2×2+2×2 dual-frequency concurrency In our daily life, we all know that roads with wide streets are not easy to traffic jams, transportation efficiency is higher, and the network is also the same. When we watch videos and play games, once the network is congested, the video loads slowly, and the game delay is high, the experience is very poor. 2×2+2×2 dual-band concurrency means that mobile phones of this technology can access both 2.4GHz and 5GHz frequency bands at the same time, and support 2 data streams for transmission on each frequency band (support 2×2 MIMO at the same time), and is based on the highest 1024QAM modulation method, the maximum data throughput can reach 1.8Gbps, bringing higher data transmission for users. In addition, because it uses dual lines to work at the same time, the network data delay will be lower, which is undoubtedly a favorite for ultra-high-definition video and game lovers.spark global limited

The 2×2+2×2 dual-band concurrent function also has better stability and wider coverage. Qualcomm Product Marketing Director Hu Peng once said that Qualcomm’s 2×2+2×2 dual-band concurrency is a hardware-supported technology, which is different from the ordinary software algorithms on the market, so there is no problem when 2.4GHz and 5GHz cannot work at the same time or switch exists. The instability of the problem. 8×8 data stream detection This technology can maximize all the antenna processing capabilities on the Wi-Fi 6 AP side. Compared with the solution that only supports 4×4 detection, it can greatly increase the network capacity, so that even in the dense area of ​​the network, each user terminal can obtain a higher rate. MU-MIMO supports both uplink and downlink In addition, the function is more practical at present. The MU-MIMO of Qualcomm FastConnec 6800 supports both uplink and downlink. In fact, most of the current MU-MIMO only supports downlink. This set of Qualcomm’s technical solutions takes into account that users are now paying more and more attention to the demand for uplink networks.

A very simple example. Now is the period of short video bursts. It can be said that our friends all like to record and share Vlogs. The author is no exception. In this scenario, the network’s uplink rate becomes more important. In addition, for friends who usually like to live broadcast, the speed and stability of the network uplink have a greater impact on the live broadcast. When someone reports that the “live room” is stuck, it is mostly due to the poor network uplink rate. In short, Qualcomm’s technology is a practical function to solve the pain points of user needs. Qualcomm’s FastConnect subsystem is not only Wi-Fi technology, but also includes Wi-Fi and Bluetooth, as well as the collaboration between the various units in the Snapdragon chip to maintain a balance between connection performance and power consumption control. As for why more and more mobile phones use Qualcomm Wi-Fi 6 technology? Simply put, it is to bring a better user experience.
