Advantages of WiFi 6E | Disadvantages of WiFi 6E

This page covers advantages and disadvantages of WiFi 6E and its basics. It mentions benefits or advantages of WiFi 6E and drawbacks or disadvantages of WiFi 6E.

What is WiFi 6E?

The wi-fi 6E extends existing wifi 6 standard which was developed as per IEEE 802.11ax to 6GHz frequency band. It offers higher speed, better performance and extremely low latency than traditional wifi 6 standard. It offers more number of simultaneous connections and offers better network performance in dense environments compare to traditional wifi standard.

The WiFi 6E operates in 6 GHz band from 5925MHz to 7125MHz range covering total of 1200 MHz bandwidth. The wifi 6E uses different number of channels as per bandwidth . It uses 59 channels in 20 MHz BW, 29 channels in 40 MHz BW, 14 channels in 80 MHz BW and 7 channels in 160 MHz BW.

WiFi 6E

The wifi 6E like wifi 6 has numerous applications which include HD video streaming (4K, 8K), VR (virtual reality), Mobile gaming, WiFi Calling at low latency, IoT, high speed tethering for data transfer, wifi kiosks, whole home gigabit coverage, cellular data offloading and so on.

Benefits or advantages of WiFi 6E

Following are the benefits or advantages of WiFi 6E:
➨It offers speeds in gigabit range. It supports up to 1.2 GHz more wifi spectrum in 6 GHz band. Upto 2 Gbps speeds are achievable in mobile phones.
➨It offers extremely low latency (< 1 ms ).
➨It offers higher capacity. Hence more number of users are supported by WiFi 6E compare to traditional wifi.
➨It offers less interference as this frequency spectrum is not common to any wireless household devices.
➨It supports wider channels in 80 MHz and 160 MHz BW (Bandwidth).
➨It extends usage of traditional wifi in 6 GHz frequency band. Hence more contiguous spectrum is available for use.

Drawbacks or disadvantages of WiFi 6E

Following are the drawbacks or disadvantages of WiFi 6E:
➨It does not support any legacy device operation in 6 GHz. But these legacy devices are supported in 2.4 GHz and 5 GHz bands.
➨6 GHz band supports shortest range compare to 2.4 GHz and 5 GHz bands.
