With the promotion and development of Wi Fi 6 in the past two years, more and more network equipment and peripheral equipment begin to support this new generation of wireless transmission technology.
For DIY players, the best choice to experience Wi Fi 6 is to replace Intel's ax 200 network card,This is also PC most mature Wi-Fi 6 solution.
Limited by the price and bandwidth of the router,It will take some time for Wi Fi 6 devices to become popular on a large scaleAt present, the most popular transmission protocol is still Wi Fi 5 (802.11ac).
And when the major terminal manufacturers are still promoting Wi-Fi 6, Intel quietly launched a few days agoThe first Wi Fi 6e wireless network card code named Typhon peakFrom the naming, it is easy to see that this new network card is an upgraded version of ax200.
The new ax210 is designed in the form of m.2230 or m.2116,In addition to Wi Fi 6e, it also supports Bluetooth 5.2 with a 2x2 antenna, 2 * 2 TX / RX stream, supporting MU-MIMO, adding support for 6GHz band, wireless transmission speed up to 3000mbps.
However, under the current 2.4GHz and 5GHz WiFi specifications, its speed and other performance are consistent with the previous generation ax200 / ax201,So this new product is difficult to play all the functions under the current network conditionsbelong to one
Among the WiFi 6e specifications that you are most concerned about,The core upgrade is to support the 6GHz bandThe bandwidth of this band reaches 1.2 GHz.
It can accommodate 7 160MHz frequency bands or 14 80MHz frequency bands at the same timeThis is very important for the already congested 2.4GHz and 5GHz environments.
Before entering the WiFi 6e era, all previous WiFi protocols were used in the 2.4GHz or 5GHz frequency band. In the current typical home / Office scenarios, there are often more than ten devices to seize these valuable bandwidth resources.
Bandwidth requirements vary from device to deviceHowever, mixed use may lead to the situation that the devices with low bandwidth requirements occupy the bandwidth resources of the devices with high bandwidth requirements, which will bring adverse impact on the user experience of devices with high bandwidth requirements.
However, 6GHz is a relatively idle frequency band. At present, there are not many devices that can occupy this frequency band,In addition, WiFi 6e can provide seven continuous 160MHz frequency bands at a time, which is very suitable for high-performance transmission.
This means that a WiFi 6e enabled system canThe traditional 2.4GHz and 5GHz frequency bands are allocated to devices with low performance requirements(for example, various IOT devices).
The clean and complete 6GHz frequency band is allocated to high-performance equipment, so as to better meet the needs of different equipment.
The main improvement of WiFi 6 802.11ax for the previous generation of 802.11ac is data throughput, andThe improvement of WiFi 6e compared with WiFi 6 focuses on data throughput and latency.
And the improvement of communication delay will become the key of WiFi 6e driving new application scenarios.
The transmission speed of 4GHz and 5GHz will not be better than that of the next generation of WiFi, and the transmission speed of 4GHz will not be better than that of the next generation.
