Wi-Fi 7 hardware is shipping, Wi-Fi 6E gear is cheap, and plenty of perfectly good Wi-Fi 6 is still being installed. If you are speccing a network right now, the question is not which is newest. It is which one your building and your devices can actually use.
Here is the short version, then the detail.
The short answer
Wi-Fi 6 — the sensible default for most offices. Mature, affordable, and it solves the density problems that matter.
Wi-Fi 6E — worth it when you have dense, high-demand rooms and can put an access point in the room. The 6 GHz band is clean and fast but stopped by walls.
Wi-Fi 7 — worth specifying on new builds and anything you expect to keep for seven years. Buy it for longevity, not for a speed number you will not hit yet.
⚠️ And the honest caveat: in almost every office we survey, Wi-Fi is not the bottleneck. More on that below.
Wi-Fi 6 (802.11ax): the density fix
Wi-Fi 6 was never really about peak speed. It was about making a crowded room work.
The features that matter:
OFDMA lets one transmission carry data for multiple devices at once, instead of every device waiting its full turn. This is the big one for offices.
MU-MIMO is the same idea for multiple simultaneous streams, in both directions.
Target Wake Time lets devices agree on a schedule for waking up, which meaningfully extends battery life on phones and IoT.
BSS Colouring tags your network so your access points stop deferring to the neighbours’ traffic — genuinely useful in a dense building.
Wi-Fi 6 operates on 2.4 and 5 GHz. It is well understood, every client device made since about 2020 supports it, and the hardware is inexpensive. For a typical small-business fit-out it remains the right call.
Wi-Fi 6E: the same standard, a new band
Wi-Fi 6E is not a new generation. It is Wi-Fi 6 with access to the 6 GHz band, which in the US added up to 1,200 MHz of previously unused spectrum.
Why that matters: 6 GHz has no legacy devices on it. No Bluetooth, no microwaves, no ancient 802.11g client dragging everything down, and in most buildings, no neighbours yet. It is clean air, and there is room for many wide non-overlapping channels.
The trade-off is physics. Higher frequency means shorter range and much worse wall penetration. A 6 GHz signal that is excellent in the room it is in may be unusable through two walls.
That makes 6E excellent for conference rooms, training rooms, trading floors, and any high-density space where you can mount an access point in the room. It is a poor choice as your only band for whole-floor coverage.
Wi-Fi 7 (802.11be): what is genuinely new
Wi-Fi 7 is a real generational step, and one feature in particular is worth caring about.
Multi-Link Operation (MLO)
This is the headline. Previously a device picked one band and stuck with it. With MLO a client can use 5 GHz and 6 GHz at the same time — aggregating them for throughput, or running the same traffic over both for reliability.
For latency-sensitive traffic — voice, video conferencing, wireless AV, anything real-time — MLO is the most meaningful Wi-Fi improvement in years. It is not a bigger number on a speed test; it is a network that stops hiccuping.
320 MHz channels
Double the width of Wi-Fi 6E’s widest channel. Impressive in a lab. In a dense multi-tenant building, 320 MHz channels mean very few non-overlapping options, so in practice we often configure narrower. Useful, but oversold in real deployments.
4K-QAM
A denser modulation scheme — roughly 20% more data per transmission, but only at short range with an excellent signal. In practice this helps devices close to the access point and does nothing at the cell edge.
Is Wi-Fi 7 worth it?
It depends entirely on what you are doing.
New build or full fit-out: Yes. The incremental cost is small against the total project, and you will not want to re-cable and re-hang access points in three years.
Replacing working Wi-Fi 6: Usually not on its own. If your Wi-Fi 6 network is properly designed and performing, Wi-Fi 7 will not fix anything.
Wireless AV, voice, real-time work: Yes — MLO is the feature you are buying.
High-density rooms: Yes, in the rooms that need it. Mixed deployments are completely normal.
Tight budget, general office: Probably not yet. Coverage, cabling and the uplink will give you far more.
💡 One practical note: client devices lag access points by years. Your Wi-Fi 7 access point will serve your Wi-Fi 6 laptop perfectly well, just at Wi-Fi 6 speeds. You are buying capability for the devices you will own later.
What is actually limiting your Wi-Fi
This is the part that saves people money. When we survey an underperforming office, the generation of the access points is almost never the cause. What we actually find:
The internet circuit. A shared, asymmetric circuit will throttle every device in the building no matter what you hang on the ceiling. We covered this in detail in our guide to dedicated fiber vs shared broadband.
Placement. Too few access points, or the right number in the wrong places. See our access point placement guide.
Channel and power planning. Everything at maximum power on overlapping channels, so the access points interfere with each other.
Cabling. A Wi-Fi 7 access point behind a 1 Gbps uplink on old Cat5e cannot deliver what it promises.
PoE budget. Wi-Fi 7 access points can draw more than older PoE budgets allow. This catches people out mid-install.
Fix those five and a Wi-Fi 6 network will comfortably outperform a badly deployed Wi-Fi 7 one.
The wiring implications nobody mentions
If you are specifying Wi-Fi 6E or Wi-Fi 7, check three things before you order hardware:
Multi-gig uplinks. A modern access point can exceed 1 Gbps of real throughput. If its uplink is a 1 Gbps port, that is your ceiling. Plan 2.5 GbE switch ports, and Cat6a cabling to the access point locations.
PoE++ (802.3bt). Higher-end Wi-Fi 7 units may want PoE++ (802.3bt). Confirm your switch’s total budget, not just its per-port rating.
Closet capacity. More radios means more heat and more power draw in the closet. Worth checking on larger deployments.
What we install, and when
For most NYC offices we are currently deploying Wi-Fi 6 and 6E as the baseline, with Wi-Fi 7 on new builds and in high-density rooms, mixed within the same site where it makes sense. Both UniFi and Cisco Meraki have solid current-generation hardware, and the right choice depends on how you want it managed rather than on the spec sheet.
What we do not do is sell a generation upgrade to fix a problem that is actually a circuit, a cable or a channel plan.
