Wi-Fi 6, 6E and 7: what the numbers mean

The names

Wi-Fi standards have technical names like 802.11ac. The industry group behind Wi-Fi gave them simpler numbers:

• Wi-Fi 5: common from around 2014. Still in many offices.
• Wi-Fi 6: arrived in 2019. Its main improvement is handling many devices at once in busy spaces.
• Wi-Fi 6E: Wi-Fi 6 plus access to a new radio band, 6 GHz, with much more room and less interference.
• Wi-Fi 7: certified from 2024. Faster again, and able to use several bands at the same time for steadier connections.

What actually changes

The biggest real-world gains in an office are usually capacity and consistency. Top speed matters less. A busy office, with dozens of laptops, phones and video calls, benefits most from Wi-Fi 6 or newer.

Things to know before upgrading

• Both ends need it. A Wi-Fi 6E access point only uses 6 GHz with devices that support it. Older devices keep working on the older bands.
• Placement matters more than the number. A modern access point in the wrong place still gives poor coverage. A site survey finds the right spots.
• The rest of the network has to keep up. Fast Wi-Fi connected to an old switch or slow internet will not feel fast.

Upgrade when your access points are aging out of support, or when the office is struggling with how many devices it has.
