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

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.

What are the benefits of Wi-Fi 6E?

• 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.

What are the drawbacks of Wi-Fi 6E?

• 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.
