WiFi 6E vs WiFI 6 | Difference between WiFi 6E and WiFi 6

This page compares WiFi 6E vs WiFI 6 and mentions difference between WiFi 6E and WiFi 6.

Introduction:
Wi-Fi 6E extends use of WiFi 6 developed as per IEEE 802.11ax into 6 GHz frequency band. This new wifi spectrum occupy up to 1.2 GHz and supports about 7 channels in 160 MHz bandwidth.

What is Wi-Fi 6E ?

The WiFi 6E delivers fastest wifi connections at low latency. These higher throughput connections are very useful for 5G services. It can be used for various use cases such as high speed tethering, multi-gigabit wifi venue capacity, wifi calling, whole home gigabit coverage, AR/VR etc.

WiFi 6E

The figure depicts different bandwidths and channels supported by WiFi 6E in various frequency ranges. The same is mentioned in the following table.

The major benefits of wifi 6E over traditional wifi are as follows.
➨More spectrum i.e. up to 1200 MHz more wifi spectrum in 6 GHz band.
➨Fully scheduled traffic with guaranteed low latency with no channel contention.
➨Greater than 1 Gbps speeds better than wifi 6 and legacy wifi devices.
➨Offers high capacity using cutting edge devices.

Frequency Band Number of channels / Bandwidth
2.4 GHz 3 in 20 MHz
1 in 40 MHz
5 GHz 25 in 20 MHz
12 in 40 MHz
6 in 80 MHz
2 in 160 MHz
6 GHz 59 in 20 MHz
29 in 40 MHz
14 in 80 MHz
7 in 160 MHz

WiFi 6E devices together with Bluetooth 5.2 offers wire class voice and music quality wirelessly. Latest Qualcomm FastConnect chips 6700 and 6900 are designed to support wifi 6E. These are being used in smartphones and VR headsets.

Difference between WiFi 6E and WiFi 6

Following table uses various parameters to derive similarities and difference between WiFi 6E and WiFi 6 technologies.

Features WiFi 6 WiFi 6E
• Frequency spectrum (GHz) 2.4 GHz, 5 GHz 2.4 GHz, 5GHz and 6 GHz (7 numbers of 160 MHz channels, no DFS)
• Availability It is available now. It will be available in 2020/2021.
• Channel bandwidth 20, 40, 80, 80+80, 160 MHz 20, 40, 80, 80+80, 160 MHz
• MU-MIMO Downlink and Uplink (8x8 DL and UL) Downlink and Uplink (8x8 DL and UL)
• Modulation 16/64/256/1024 QAM 16/64/256/1024 QAM
• Clients per channel OFDMA - up to 74 clients (160 MHz channel) OFDMA - up to 74 clients (160 MHz channel)
• Max. Data Rate ~ 1.5 Gbps per device) Higher than wifi6 and other traditional wifi devices, 2.3 Gbps per device
• Capacity (Number of channels) Lower Higher
• Latency Higher Extremely lower
• Network performance Good Better (In dense congested environments)
• Coverage range More (in 2.4 GHz and 5 GHz bands) Less ( in 6 GHz band)

Conclusion: Due to high bandwidth, low latency and more number of channels it is the future of next generation wifi. As mentioned it enables 4K/8K video streaming, real time cloud gaming, real time data transfer at high speed, IoT (Internet of Things), 5G and more.
