What are the benefits and drawbacks of Wi-Fi 6E?

Answer

Wi-Fi 6E is a new band that was added with the introduction of Wi-Fi 6. This allows the use of 6 GHz spectrum.

More capacity - The use of 6 GHz allows for up to 1.2 GHz of new spectrum.

Note: Not all countries/regulatory regions use all of the spectrum allowed. Please check the requirements of your specific regions.
More Channels - With the additional frequencies this allows for more channels:
- Up to 59 20 MHz wide channels.
- Up to 29 40 MHz wide channels.
- Up to 14 80 MHz wide channels.
- Up to 7 160 MHz wide channels.
No Legacy Devices - The 6 GHz band requires the use of Wi-Fi 6E and OFDMA, so no legacy devices will be able to use the channels. Meaning that there is not any slowdown due to having to support older devices.
No interference from Microwave Ovens - The 6 GHz band is outside of the frequencies of microwave ovens, so it is not susceptible to interference from them.

Range - The 6 GHz has a shorter wavelength than 2.4 GHz or 5 GHz, so it will not broadcast as far.
Interference - With a shorter wavelength, it is not as good at penetrating walls and other obstructions as 2.4 GHz and 5 GHz can.
