Wi-Fi 6E, is an updated version of Wi-Fi 6 that operates in the newly allocated 6 GHz frequency band. Operating in this new frequency band, allows Wi-Fi 6E to provide higher performance, lower latency, and faster data rates than Wi-Fi 6 and traditional Wi-Fi technology. Wi-Fi 6E uses the 1200 MHz of newly added spectrum from 5.925 to 7.125 GHz.

Wi-Fi 6E has been created to deal with the “spectrum shortage” being faced by the Wi-Fi technology i.e the increasing demand for Wi-Fi will (or will soon) exceed the actual capacity of the currently available unlicensed spectrum. Wi-Fi 6E will help to fix this shortage by providing adjacent spectrum blocks to accommodate up to fourteen additional 80 MHz channels or seven 160 MHz channels for applications such as high-definition video streaming and virtual reality. The idea behind launching Wi-Fi 6E is to enable more simultaneous connections, to use the available bands in a more efficient manner, and to reduce power consumption. 

The new spectrum is right above the existing 5 GHz spectrum (Wi-Fi 6) and allows for denser networks by increasing the number of Wi-Fi channels that can be used, as explained above. Wi-Fi 6E devices will leverage these wider channels and additional capacity to deliver greater network performance and to share the network simultaneously, even in very dense and congested environments.

Applications of Wi-Fi 6E

As Wi-Fi 6E has brought significant improvement in throughput and has remarkably improved Wi-Fi latency for close-range communications, it can be used for a number of demanding applications such as:

  • 4K and 8K streaming
  • Low latency Wi-Fi calling
  • Mobile AR / VR gaming
  • Delivering efficient gigabit Wi-Fi in smart homes
  • High-speed tethering
  • Real-time gaming
  • Indoor public venues
  • Industrial IoT
  • Data offload from 5G Network
