Chinese-English Translation:

Wi-Fi 6E主要在原有的2.4GHz和5GHz频段之外增加了一个新的频段:6GHz频段。峰值速率可以达到 3.6Gbps。Wi-Fi6E还具备低于3毫秒的超低时延。

Wi Fi 6e mainly adds a new band in addition to the original 2.4GHz and 5GHz bands: 6GHz band. The peak rate can reach 3.6gbps. The wi-fi6e also has an ultra-low latency of less than 3 milliseconds.

虽然 Wi-Fi6 已经很强大了,不过随着现在智能家居的普及物联网的高速发展,家庭中连接无线数量的设备也在大幅度增加,这将会导致 2.4GHz 和 5GHz 频段过度拥塞,从而让 Wi-Fi 难以充分发挥其潜力。Wi-Fi 6 相较于 Wi-Fi 5 的提升,主要有 4 大优势——高带宽、高并发、低时延,低功耗。

Although Wi Fi 6 is already very powerful, with the popularity of smart home and the rapid development of Internet of things, the number of wireless devices in the home is also increasing significantly, which will lead to excessive congestion in 2.4GHz and 5GHz bands, making it difficult for Wi Fi to give full play to its potential. Compared with Wi Fi 5, Wi Fi 6 has four advantages: high bandwidth, high concurrency, low delay and low power consumption.

Wi-Fi6E 和 Wi-Fi6 的区别

The difference between wi-fi6e and wi-fi6

新增 6GHz 频段,Wi-Fi 6E 相比 Wi-Fi 6 多出的一个“E”,代表的是“Extended”,也就是扩展的意思。主要在原有的 2.4GHz 和 5GHz 频段之外增加了一个新的频段:6GHz 频段。

A new 6GHz band is added. Compared with Wi Fi 6, Wi Fi 6e has an extra “e”, which means “extended”. In addition to the original 2.4GHz and 5GHz band, a new band is added: 6GHz band.

也就是说 Wi-Fi 6E 无线路由器是支持 2.4GHz、5GHz 和 6GHz 三频的,这样就可以很好解决上面说到的 2.4GHz 和 5GHz 频段拥塞的问题。对于智能家居、老旧设备和对网络要求不高的设备可以连接 2.4GHz 和 5GHz 频段,而对网络要求高的设备可以连接到新的频段 6GHz 频段,提高网络体验。

In other words, Wi Fi 6e wireless router supports 2.4GHz, 5GHz and 6GHz, which can solve the congestion problem of 2.4GHz and 5GHz. For smart home, old devices and devices with low network requirements, 2.4GHz and 5GHz bands can be connected, while devices with high network requirements can be connected to the new 6GHz band to improve the network experience.

6GHz 频段也带来了更多的信道,6GHz 频段范围处于 5925-7125MHz 之间,包含 7 个 160MHz 信道、14 个 80MHz 信道、29 个 40MHz 信道、60 个 20MHz 信道,总计 110 个信道,相比较 5Ghz 的 45 以及 2.4Ghz 的 4 个信道,容量更大,吞吐量大大提升。

6GHz band also brings more channels. The range of 6GHz band is between 5925-7125mhz, including 7 160MHz channels, 14 80MHz channels, 29 40MHz channels and 60 20MHz channels, with a total of 110 channels. Compared with 5GHz 45 and 2.4GHz 4 channels, the capacity is larger and the throughput is greatly improved.

在设备密度高的地方,信道的增加就可以让用户有更多的选择,减少互相之间的信号干扰。比如大学宿舍,如果设置 160MHz 频宽,那么只有两个选择,但是宿舍又是一个无线路由器密集的地方,这样就大大增加了相互之间的信号干扰。

In places with high equipment density, the increase of channel can give users more choices and reduce the signal interference between each other. For example, if the bandwidth of 160MHz is set in the university dormitory, there are only two options, but the dormitory is also a place with dense wireless routers, which greatly increases the signal interference between each other.

速率新突破

New breakthrough in speed

Wi-Fi 6E 在手机芯片上也有很大的提升,峰值速率可以达到 3.6Gbps。而目前支持 Wi-Fi 6 的手机芯片峰值速率只有 1.774 Gbps。

Wi Fi 6e is also greatly improved in mobile phone chips, with a peak speed of 3.6gbps. At present, the peak speed of mobile phone chips supporting Wi Fi 6 is only 1.774 Gbps.

时延更低

Lower delay

Wi-Fi6E 还具备低于 3 毫秒的超低时延,相比前代,密集环境下的时延降低超过 8 倍。

Wi-fi6e also has an ultra-low delay of less than 3 milliseconds, which is more than 8 times lower than the previous generation in dense environments.

从技术到商用

From technology to business

虽然高通已经发布支持 Wi-Fi 6E 的路由器芯片和手机芯片,不过距离 Wi-Fi 6E 普及还有一段时间,短期内你不会真正看到它密集出现,毕竟还有人没体验到 Wi-Fi 6。

Although Qualcomm has released router chips and mobile phone chips that support Wi Fi 6e, there is still a period of time before the popularity of Wi Fi 6e. You will not really see the dense emergence of Wi Fi 6e in the short term. After all, there are still people who have not experienced Wi Fi 6.
