Wi-fi6 after nearly two years of promotion and development, more and more network devices and peripheral devices began to join the support of this new generation of wireless transmission technology.

For the majority of DIY players, the best choice to experience wi-fi6 is to replace Intel’s ax200 network card, which is also the most mature wi-fi6 solution for PC.

However, limited by the price of the router and the limitation of the network bandwidth, it will take some time for the large-scale popularization of wi-fi6 devices. At present, the most popular transmission protocol is still wi-fi5 (802.11ac).

Intel wireless network card has become the most mature WiFi 6 solution for PC

While major terminal manufacturers are still promoting wi-fi6, Intel just a few days ago quietly launched its first wi-fi6e wireless network card, model ax210, code named typoonpeak. It is not difficult to see from the naming that this new network card is an upgraded version of ax200.

The new ax210 adopts m.22230 or m.21216 configuration design. In addition to supporting wi-fi6e, it also supports Bluetooth 5.2, equipped with 2×2 antenna, 2 * 2 TX / RX stream, supports MU-MIMO, and adds support for 6GHz band. The wireless transmission speed can reach up to 3000mbps.

However, in the current 2.4GHz and 5GHz WiFi specifications, its speed and other performance are consistent with the previous generation of ax200 / ax201, so this new product is difficult to play all the performance under the current network conditions, and belongs to a “war in the future” product.

Among the most concerned WiFi 6e specifications, the core upgrade is to support the 6GHz band, which has a bandwidth of 1.2Ghz.

It can accommodate 7 160MHz bands or 14 80MHz bands at the same time, which is very important for the already crowded 2.4GHz and 5GHz environments.

Before entering the era of WiFi 6e, all previous WiFi protocols were used in the 2.4GHz or 5GHz band. In the current typical home / office scenario, there are often more than ten devices to seize these valuable bandwidth resources.

Different devices have different requirements for bandwidth, and 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 has a negative impact on the user experience of the devices with high bandwidth requirements.

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 the traditional 2.4GHz and 5GHz frequency bands can be allocated to devices with low performance requirements (such as various IOT devices) using the system supporting WiFi 6e.

The clean and complete 6GHz band is allocated to high-performance equipment, so as to better meet the needs of different equipment.

The main improvement of wifi6802.11ax for the previous generation 802.11ac is data throughput, while the improvement of wifi6e is focused on data throughput and delay.

The improvement of communication delay will be the key of WiFi 6e driving new application scenarios.

Wifi6e may not be dominant in such features as through the wall. The higher speed and lower delay will be mainly concentrated in the short-range transmission. Therefore, the new generation of transmission technology will still be mixed with 2.4GHz and 5GHz.
