Wi-Fi 6, which refers to the 6th generation of wireless networking technology. Compared with the 5th generation, the first feature is the speed increase, the network connection speed increased 1.4 times. The second is technological innovation. The application of OFDM orthogonal Frequency division multiplexing technology and MU-MIMO technology enables Wi-Fi 6 to provide stable network connection experience for devices even in multi-device connection scenarios and maintain smooth network operation. Compared with WiFi5, WiFi6 has four main advantages: fast speed, high concurrency, low latency, and low power consumption.
The extra E in Wi-Fi 6E stands for "Extended". A new 6GHz band has been added to the existing 2.4ghz and 5Ghz bands. Because the new 6Ghz frequency is relatively idle and can provide seven consecutive 160MHz bands, it has very high performance.
The 6GHz frequency band is between 5925-7125MHz, including 7 160MHz channels, 14 80MHz channels, 29 40MHz channels, and 60 20MHz channels, for a total of 110 channels.
Compared with 45 channels of 5Ghz and 4 channels of 2.4Ghz, the capacity is larger and the throughput is greatly improved.
What is the difference between Wi-Fi 6 and Wi-Fi 6E?
“The most influential difference is that Wi-Fi 6E devices use a dedicated 6E spectrum with up to seven additional 160 MHz channels while Wi-Fi 6 devices share the same congested spectrum — and only two 160 MHz channels — with other legacy Wi-Fi 4, 5, and 6 devices,” according to Intel's website.
In addition, WiFi6E has the following advantages compared with WiFi6.
1. New peak in WiFi speed
In terms of performance, the peak speed of the WiFi6E chip can reach 3.6Gbps, while the current peak speed of the WiFi6 chip is only 1.774Gbps.
2. Latency reduction
WiFi6E also has an ultra-low latency of less than 3 milliseconds. Compared with the previous generation, the latency in dense environments is reduced by more than 8 times.
3. Improved Bluetooth technology of mobile terminal
WiFi6E supports the new Bluetooth 5.2 technology, which improves the overall use experience of mobile terminal devices in all aspects, bringing better, more stable, faster and wider user experience.
