A quote for new access points arrives with “Wi-Fi 7” and “tri-band” on the first line, and it’s tempting to read that as a faster network. It isn’t, quite. A wireless network is two ends and a cable, and the new standard mostly helps where the laptop, the radio rules, the switch port and the power budget all play along. That’s worth sorting out before you commit to a refresh, and none of it is difficult once the pieces are separated.
What 6 GHz adds, and what Ofcom said about it
Wi-Fi 6E is Wi-Fi 6 used in the 6 GHz band. The Wi-Fi Alliance introduced its certification on 7 January 2021 as part of Wi-Fi CERTIFIED 6, bringing the same features (OFDMA, which shares a channel between several devices at once; target wake time; and MU-MIMO, which lets an access point talk to several devices simultaneously) to the new spectrum. For an office, the point is more room: a band of its own, apart from 2.4 and 5 GHz.
How much room depends on the country. In the UK, Ofcom’s July 2020 statement made the lower 6 GHz band, 5925 to 6425 MHz, available for Wi-Fi and other RLAN (radio local area network) technologies. That’s 500 MHz, and dividing it up tells you how many wide channels could fit: three at 160 MHz or one at 320 MHz (6425 minus 5925 is 500, 500 divided by 160 is 3.125 so three, and 500 divided by 320 is 1.56 so one). That’s our arithmetic, not a figure from Ofcom.
Ofcom’s statement of 9 January 2026 added a decision to allow outdoor and higher power Wi-Fi in the lower band under the control of an Automated Frequency Coordination (AFC) system. A separate consultation that closed on 20 March 2026 proposed that Standard Power Wi-Fi access points and fixed client devices would query an AFC system for permitted frequencies and power before transmitting. The January statement also proposed sharing the upper band (6425 to 7125 MHz), with 6425 to 6585 MHz as a Wi-Fi priority portion and 6585 to 7125 MHz as the mobile priority portion, where Wi-Fi would be allowed early only under AFC control. As at June 2026 those upper band arrangements were proposals, so an office design that depends on them is a bet.
For an ordinary indoor office we’d expect AFC to be the minor part of the story, though the power class of the access points you buy is worth checking on the data sheet. We haven’t quoted power limits for the lower band because the figures belong in the vendor’s UK regulatory documentation and in Ofcom’s rules, and it’s worth asking for both when you get a quote.
What Wi-Fi 7 adds, and what needs the other end
Two names are in play. Wi-Fi 7 is the Wi-Fi Alliance’s certification programme, and 802.11be is the IEEE amendment it’s generally associated with. The IEEE board approved 802.11be on 26 September 2024 and, according to IEEE, it was published on 22 July 2025. The Alliance had introduced Wi-Fi CERTIFIED 7 on 8 January 2024, so certification began before the standard was published. For buying, we’d look for the certification on a data sheet.
Three features matter in an office, and each depends on something besides the access point.
- Wider channels. The Alliance describes 320 MHz channels as doubling the widest channel size, which it describes as available in countries that make the 6 GHz band available to Wi-Fi. In the UK that means the lower band, where, by the arithmetic above, you’d have one. A single wide channel shared by every access point on a floor is not a plan, so whether to use 320 MHz at all is a design decision for the survey.
- Multi-Link Operation. Devices send and receive over several links at once, which the Alliance says increases throughput, reduces latency and improves reliability. Both ends will need to support it, so it only helps if your clients do.
- 4096-QAM. The Alliance’s January 2024 release says it achieves 20% higher transmission rates than 1024 QAM. A higher modulation order generally needs a stronger, cleaner signal, so we’d expect the gain close to the access point, and you should measure it before you count on it.
The release doesn’t say which of these are mandatory, so don’t assume a Wi-Fi 7 label means all three. Equally, 802.11be is backward compatible with older devices in 2.4, 5 and 6 GHz, so the standard is built to keep older clients working, and they’ll behave as the older devices they are.
Clients decide what you see
This is the section that changes purchasing decisions. A laptop whose radio is Wi-Fi 6 connects to a Wi-Fi 7 access point as a Wi-Fi 6 laptop. One without a 6 GHz radio never touches the 6 GHz band, however many access points you hang from the ceiling. How many devices in your estate have these radios is something to count, not assume, and for most offices we’d do that before looking at a single data sheet.
A simple inventory does the job. List the laptops, phones, tablets, scanners and handhelds that matter, with the wireless standard each one’s data sheet or system report gives, and mark the ones due for replacement in the next two or three years. If most of the estate is Wi-Fi 5 or Wi-Fi 6 on 5 GHz, the new access points will serve it as they would have served it anyway. Handheld scanners and printers deserve a particular look, because older radios are common in such devices and they’re easy to forget.
Planning around the access point
The data sheet matters more than the label. Whether a Wi-Fi 7 model has a 6 GHz radio at all is a data sheet question, because the standard covers 2.4 and 5 GHz as well. Read the number of radios, the bands each one uses and the uplink port speed.
That last item is cabling and switching. If the access point lists an uplink faster than 1 Gbit/s, the switch port and the run of cable need to be able to carry it, and the data sheet tells you what category of cable the vendor expects. Power over Ethernet is the same kind of question. IEEE 802.3bt raised the maximum power by using all four pairs of the cable, so check each switch’s total PoE budget against the access points it powers, and each port’s PoE class (the power level it can supply) against what the model requires, and whether the data sheet describes reduced operation.
Channel plans change too. With 6 GHz you’ll be choosing width and channel per access point, or letting the controller choose them, and the width you pick changes how many channels you can reuse across a floor. A wireless survey and access point planning exercise answers what a diagram can’t: how the building’s walls treat a band you aren’t using yet. We wouldn’t take a rule of thumb on trust for 6 GHz, and a survey with the band switched on is the way to measure it.
Management is the last piece. Controller or cloud-managed access points differ in how they handle 6 GHz settings and firmware, and in who can see the radio reports. If you manage the estate from a controller, check it supports the new radios before you order.
When not to buy it
We’d hold off in any of these cases.
- Your clients can’t use it. If the devices that matter are on 5 GHz Wi-Fi 5 or 6, you’d be paying for capability that sits idle. Our earlier post on choosing a Wi-Fi solution covers the Wi-Fi 6 and 5 comparison.
- The cabling or switching can’t keep up. An access point on a switch that cannot supply the PoE class it needs may run in a reduced mode or not run at all, and one on a 1 Gbit/s uplink may be held below its headline speed. The data sheet should say which.
- Your current network works. If complaints are about dead spots, roaming or an overloaded 2.4 GHz band, a survey is likely to find a placement or configuration fix before it finds a standards gap.
- Your plan relies on rules still being decided. The upper 6 GHz band and AFC conditions were still out for consultation.
A refresh that follows the client estate, the cabling and the power budget is a better one than a refresh that follows the label. A survey with the 6 GHz radios switched on shows where access points belong and how clients roam between them. If you’re weighing a refresh, get in touch and we’ll work through whether your clients, cabling and power budget justify it.
