Wi-Fi 6 vs Wi-Fi 6E vs Wi-Fi 7: Which Should a Business Buy?
Wi-Fi 6 is still a sound choice for most offices on a budget. Wi-Fi 6E adds the 6 GHz band, which gives newer devices clearer channels. Wi-Fi 7 adds multi-link operation and faster peak speeds, and it works with older devices too. For a new installation that should last several years, a Wi-Fi 7 access point now costs little more than Wi-Fi 6 and is the one we would usually suggest.
The three standards side by side
| Wi-Fi 6 | Wi-Fi 6E | Wi-Fi 7 | |
|---|---|---|---|
| IEEE name | 802.11ax | 802.11ax (extended to 6 GHz) | 802.11be |
| Bands | 2.4 and 5 GHz | 2.4, 5 and 6 GHz | 2.4, 5 and (on tri-band models) 6 GHz |
| Widest channel | 160 MHz | 160 MHz | 320 MHz (6 GHz only) |
| Headline additions | OFDMA, MU-MIMO, target wake time | Access to the 6 GHz band | Multi-link operation (MLO), 4K-QAM, wider channels |
What Wi-Fi 6 brought
Wi-Fi 6 was designed for busy networks. OFDMA lets an access point serve several devices in one transmission instead of taking turns, which helps in offices and classrooms full of phones and laptops. Wi-Fi 6 access points such as the EAP610 and EAP653 remain a cost-effective way to replace older Wi-Fi 5 equipment.
What Wi-Fi 6E adds: the 6 GHz band
Wi-Fi 6E uses the same technology as Wi-Fi 6 but adds a third band at 6 GHz. In the UK, Ofcom opened the lower part of the 6 GHz band (5925–6425 MHz) to Wi-Fi. Because only 6E and 7 devices can use it, it is free of the older equipment and neighbouring networks that crowd 2.4 and 5 GHz. The trade-off is range: 6 GHz signals fade faster through walls, so it works best in the same room as the access point.
In our range, 6E appears mainly in home mesh, for example the Deco XE75 tri-band system.
What Wi-Fi 7 adds
- Multi-link operation (MLO): a Wi-Fi 7 device can use more than one band at once, or switch between them without dropping, which helps with consistency on calls.
- 4K-QAM: packs more data into each transmission when signal is strong.
- 320 MHz channels: very wide channels in the 6 GHz band for peak speed. In the UK there is only room for a limited number of these, so in a busy building narrower channels are often the better setting.
Wi-Fi 7 access points work with Wi-Fi 6, 5 and older devices. Those devices simply connect using their own standard.
Dual-band or tri-band Wi-Fi 7?
This is the detail that matters when you compare models. Some Wi-Fi 7 access points are dual-band and do not use 6 GHz at all. The Omada EAP723 (BE3600) and EAP727 (BE5000) are dual-band: they bring MLO and 4K-QAM on 2.4 and 5 GHz, and suit sites where most devices do not yet support 6 GHz. The EAP772 (BE9300) is tri-band, with TP-Link quoting up to 5760 Mbps on 6 GHz, and suits offices and venues where newer laptops and phones are common.
The same split exists in Deco: the Deco BE25 is dual-band Wi-Fi 7, while the Deco BE65 range is tri-band.
Do not forget the wiring
The faster Wi-Fi 7 access points have 2.5G Ethernet ports. On a gigabit switch port they still work, but the cable becomes the bottleneck. If you are buying Wi-Fi 7 for speed, pair it with a 2.5G PoE+ switch and good Cat6 cable. Wi-Fi 7 access points can also draw more power: check the switch's budget with our guide to PoE budgets.
Which should you buy?
| Situation | Our suggestion |
|---|---|
| Replacing old Wi-Fi on a tight budget, mostly older devices | Wi-Fi 6 (EAP610, EAP653) |
| New installation, mixed devices, gigabit switches | Dual-band Wi-Fi 7 (EAP723, EAP727) |
| Newer laptops and phones, busy rooms, 2.5G switching | Tri-band Wi-Fi 7 (EAP772) |
| Large home | Deco mesh in Wi-Fi 6, 6E or 7 (see our large homes guide) |

Frequently asked questions
Is Wi-Fi 7 worth it for a small business?
For a new installation it usually is: Wi-Fi 7 access points cost little more than Wi-Fi 6, work with older devices and will suit newer laptops and phones as they arrive.
Do I need Wi-Fi 7 devices to use a Wi-Fi 7 access point?
No. Wi-Fi 7 access points work with Wi-Fi 6, 5 and older devices. You only get Wi-Fi 7 features, such as multi-link operation, on devices that support them.
What is the difference between Wi-Fi 6E and Wi-Fi 7?
Wi-Fi 6E is Wi-Fi 6 with access to the 6 GHz band. Wi-Fi 7 adds multi-link operation, 4K-QAM and 320 MHz channels, and not every Wi-Fi 7 access point uses 6 GHz.
Is 6 GHz Wi-Fi allowed in the UK?
Yes. Ofcom has opened the lower 6 GHz band, 5925 to 6425 MHz, for Wi-Fi use.
