Wi-Fi 6E Explained
Wi-Fi 6E represents a huge advance over Wi-Fi 6. Previous generations of Wi-Fi have all shared small number of available channels, leading to interference and congestion. Intel® Wi-Fi 6E (Gig+) products let you take advantage of exclusive channels and features, bringing the VIP benefits of Wi-Fi 6E to home, business, and gaming users.
What Is Wi-Fi 6E?
The next step in Wi-Fi evolution will enhance wireless performance by opening up new, exclusive channels never before available for unlicensed Wi-Fi use.
Wireless signals are transmitted within specific unlicensed spectrum ranges, as made available by law. The last three generations of wireless technology have used two signal bands. The first, the 2.4 GHz band, is crowded with interference from many devices, including baby monitors and microwaves. The 5 GHz band has now also become congested with legacy Wi-Fi devices and networks.
A new 6 GHz band will be used by Wi-Fi 6E connections—and not legacy devices. It’s called Wi-Fi 6E because it represents an extension of the available frequencies that can be used to transmit Wi-Fi 6 signals. United States regulators were the first to approve the 6 GHz spectrum for Wi-Fi use in 2020, allowing development and deployment of Wi-Fi 6E devices to move forward.
Comparing Wi-Fi 6E and Wi-Fi 6
Before choosing a new wireless device, it’s important to know the key differences between Wi-Fi 6E and the previous generation of wireless technology, Wi-Fi 6. The most impactful difference is that Wi-Fi 6E devices use a dedicated 6E spectrum with up to seven additional 160 MHz channels while Wi-Fi 6 devices share the same congested spectrum—and only two 160 MHz channels—with other legacy Wi-Fi 4, 5, and 6 devices. This gives Wi-Fi 6E devices the advantage and ability to experience gigabit speeds more easily. Wi-Fi 6 devices will not be able to take advantage of the benefits of the 6 GHz spectrum used by Wi-Fi 6E.
Additionally, Wi-Fi 6E devices, like a Wi-Fi 6E notebook, are backward compatible with legacy wireless technologies like Wi-Fi 6 and Wireless-AC and will be able to connect to legacy Wi-Fi 4, 5, and 6 networks in legacy 2.4/5 GHz bands when needed.
Product and Performance Information
Based on IEEE 802.11ax specification legacy 5 GHz vs. new 6 GHz Wi-Fi spectrum. With more large channels in 6 GHz, technology advantages of Wi-Fi 6E networks enable higher maximum theoretical PC client speeds vs. 5 GHz Wi-Fi 5.
Based on IEEE 802.11ax specification. 160 MHz channels and Wi-Fi 6/6E technology advantages enable significantly higher maximum theoretical PC client speeds vs. standard Wi-Fi 5 products.
Based on IEEE 802.11ax specification Intel Engineering simulation. 160 MHz channels and Wi-Fi 6/6E technology advantages related to network managed traffic enable lower latencies, more efficient operation, and higher reliability vs. random contention-based traffic of standard Wi-Fi 5 networks.
