6 GHz in the EU: An Empty Highway With a Toll Booth
Less Spectrum, Still a Win
6 GHz in the EU: An Empty Highway With a Toll Booth
Wi-Fi 6E got certified back in January 2021, so 6 GHz-capable clients and APs have been out in the wild for more than five years now. Adoption was slow at first, but with Wi-Fi 7 in full swing and older gear getting pushed to end-of-life, the band is finally starting to see real traffic.
Think of 6 GHz as a brand new highway that was built years ago and is only now getting cars on it. In the US that highway has eight lanes, no toll booth, and the speed limit is "yes." In the EU... well, let's talk about that.
The dream scenario (a.k.a. the US)
The FCC opened the full 1200 MHz (5925–7125 MHz) for unlicensed use, with three power modes:
LPI (Low Power Indoor) — 30 dBm EIRP, indoor only, no coordination needed.
SP (Standard Power) — up to 36 dBm EIRP, indoor or outdoor, requires AFC.
VLP (Very Low Power) — 14 dBm EIRP, portable, no coordination.
AFC = Automated Frequency Coordination (not "Automatic Frequency Control" — I had to look it up too). The FCC doesn't actually run it; they certify third-party operators like Federated Wireless, Wi-Fi Alliance, and Comsearch that run cloud databases. The AP phones home with its geolocation and height, the AFC service checks against incumbents (fixed satellite, microwave backhaul), and replies with the channels and max power it's allowed to use. APs re-query every 24 hours or so.
AFC went live in the US in 2024. Outdoor 6 GHz at full blast is real. Sounds like a dream, right? Now hold that thought.
So what's the deal in the EU?
Short version: we got the smaller stretch of road, and we lost the upper exit ramps to the mobile crowd.
At WRC-23, the upper 6 GHz band (6425–7125 MHz) was allocated to IMT (mobile) in ITU Region 1. The mobile operators won that fight. What we kept is the lower 480 MHz (5945–6425 MHz), under LPI only:
23 dBm EIRP composite
−1 dBm/MHz PSD
Indoor only, integrated antennas
No DFS
To make matters worse, the EU has no published plan for an AFC equivalent. And even if CEPT pulls one out of the hat tomorrow, I really don't think we're getting 36 dBm. Probably more likely something around 30 dBm, like U-NII-3 in the US, or just whatever caps already apply to 5 GHz outdoor here.
So should we all gather forces, march to Brussels, and demand they release those bands? Probably not the most productive use of a Tuesday. The decision is made. Let's work with what we've got.
Is all lost? (Spoiler: no.)
Even with the EU's modest 23 dBm cap, this isn't actually a downgrade. That's the same power as our U-NII-1 indoor 5 GHz channels... so on the power side, no loss (haha).
But 6 GHz is a higher frequency, so path loss is worse. Free-space loss at 6 GHz is about 1.5 dB more than 5 GHz, which translates to roughly 15–20% less coverage at the same power. Plan for tighter cells.
Here's the kicker though, and honestly the part I keep coming back to: no DFS. Anyone who has watched a deployment fall apart because every U-NII-2C channel keeps bouncing on phantom radar hits knows exactly how big a deal this is. 480 MHz of contiguous, non-DFS spectrum is a huge step forward from the 5 GHz reality most of us deal with.
On top of that:
The band is clean — no legacy 802.11a/n/ac noise (yet)
Wi-Fi 7 features like MLO and 320(160) MHz channels finally have room to breathe
WPA3-only requirement means a security floor by default
So, should you bother with 6 GHz in the EU?
Yes. With proper planning, implementation, and (*cough) actual site survey and design (*cough) the benefits outweigh the regulatory limits. The EU's 6 GHz situation is worse than the US, outdoor SP isn't coming any time soon, and we'll probably never see 36 dBm here. None of that changes the fact that 480 MHz of non-DFS spectrum at LPI power is still a clear win over 5 GHz for indoor enterprise WLANs today.
The highway is shorter than we'd like, but it's open, it's empty, and the toll is reasonable. Get on it.
