Wi-Fi 6E: Wi-Fi® in the 6 GHz band

Wi-Fi Alliance Paper: "Wi-Fi 6E: Wi-Fi in the 6GHz band"

In a technical paper released in January of 2021 by the Wi-Fi Alliance, the authors break down Wi-Fi 6E’s various economic and technical benefits. The paper first gives the reader insight into a general overview of 6E’s benefits and capabilities. As the paper progress's the reader can obtain a detailed understanding of what Wi-Fi 6E has to offer. Some of these benefits include Increased channel sizes, improved Wi-Fi security, and optimized network performance.

In continuation, this paper emphasizes the impact Wi-Fi has had on the world since its introduction in 1991. The global dependence on Wi-Fi was made clear with the widespread issues COVID-19 brought. Companies, Academic institutions, and many individuals were forced to transition to online environments - all powered by Wi-Fi. In this part of the paper, Wi-Fi Alliance demonstrates its effectiveness and reliability by explaining the exponentially growing acquisition of Wi-Fi

The Wi-Fi Alliance explains that the need for more data spectrum is satisfied with the implementation of Wi-Fi 6E. 6E offers 1200 MHz of usable spectrum in the 6 GHz band. Devices that are labeled as a Wi-Fi 6 generation device will have full access to the benefits of 6E. As a result, wider channels can be utilized, and less interference will occur.

As we continue to head into a world with increasingly demanding applications, Wi-Fi 6E serves as a viable solution. With the occurrence of wider channels, data can be transferred faster fulfilling the needs of these applications. The paper further explores exactly what 6E offers to fulfill such tasks.

6E’s use cases are reviewed through a graphical demonstration. Through this visual, the reader can obtain a better understanding of what type of connectivity scenarios are most favorable for 6E.

Finally, the paper outlines the following 6E key features.
