On 7 September 2026 the mobile industry made its clearest move yet on a slice of spectrum that Wi-Fi has been counting on. The GSMA, meeting in Kuala Lumpur, told regulators that the global mobile ecosystem is ready to deploy in the upper 6 GHz band and asked governments to plan it for licensed mobile use. Router buyers have a fair question in response. Does this mean the 6 GHz band on a new Wi-Fi 7 router is about to shrink? The honest answer depends entirely on where you live, and in Europe most of it has already been decided.
What the GSMA asked for, and when
The GSMA published its statement on Monday 7 September 2026. It says countries accounting for more than 80 percent of the world's population now support mobile use of the upper 6 GHz band, following harmonisation at the World Radiocommunication Conference in 2023.
More than 60 operators, device makers, chipset vendors and network suppliers signed on to the same message. The ask is specific. Regulators should put the full upper 6 GHz band into national roadmaps and make it available for full-power macro-cell mobile use. The GSMA argues the band can carry the 200 to 400 MHz channel widths that 6G is expected to need.
First assignments of the band have already been completed, according to the same statement, with further awards expected across Europe, the Middle East, Africa, Asia-Pacific and the Americas.
The band in question, in plain numbers
The 6 GHz band splits into two halves in regulatory language. Lower 6 GHz runs from 5945 to 6425 MHz, which is 480 MHz wide. Upper 6 GHz runs from 6425 to 7125 MHz, which is 700 MHz wide.
Wi-Fi 6E introduced the 6 GHz band, and Wi-Fi 7 leans on it harder because 320 MHz channels only fit there. So the width a country grants to Wi-Fi in 6 GHz decides how much of Wi-Fi 7 you can actually use.
At the 2023 conference, footnote RR 5.457E identified 6425 to 7125 MHz for mobile service in Region 1, which covers Europe, Africa and the Middle East, and 7025 to 7125 MHz in Region 3. An identification is not an allocation to one side. It puts mobile on the table alongside the existing uses, and leaves the choice to each country.
Europe already made a provisional decision
This is the part missing from most coverage of the GSMA statement. Europe did not wait.
The Radio Spectrum Policy Group, which advises the European Commission, adopted an Opinion in Brussels on 12 November 2025 after a public consultation that ran from 20 June to 31 August 2025. It agreed a prioritised split of the upper 6 GHz band, and the numbers are firm.
The segment from 6585 to 7125 MHz is prioritised for full-power mobile networks. That is 540 MHz handed to the mobile side as the recommended direction. The group also asked European spectrum bodies to study whether Wi-Fi could still operate there on a non-prioritised basis, meaning without causing interference to mobile, but that remains a study rather than a decision.
So the GSMA is not asking Europe for something Europe has refused. It is pressing for the last step in a direction European advisers have already chosen.
The 160 MHz that nobody gets yet
Between the Wi-Fi half and the mobile half sits a strip from 6425 to 6585 MHz, and its treatment is the most interesting detail in the whole file.
The Opinion holds that 160 MHz as a guard band. Its job is to protect existing Wi-Fi in lower 6 GHz from full-power mobile transmitters sitting next door. Member States are advised not to release it to either service for now.
What happens to it later depends on a conference. If the 2027 World Radiocommunication Conference identifies 7125 to 7250 MHz for mobile, the Opinion says there is a strong case for designating that 160 MHz for Wi-Fi as a primary use. If the conference does not, the strong case runs the other way, toward mobile. Wi-Fi's chance of regaining ground in Europe therefore rests on mobile finding room above the band instead.
What this does to channel width in practice
Numbers make the consequence concrete. Europe currently opens 5945 to 6425 MHz to Wi-Fi, which is 480 MHz. Divide that and you get three 160 MHz channels, or a single 320 MHz channel with nothing left over.
The United States opens 5.925 to 7.125 GHz, which is 1200 MHz. That yields up to seven 160 MHz channels or three 320 MHz channels.
One 320 MHz channel is not nothing, but it is fragile. A single neighbouring network on the same width leaves you nowhere to move. Three such channels give a router somewhere to go. That difference, rather than any headline speed figure, is the real gap between a Wi-Fi 7 router running in Europe and the same model running in the United States.
Worth stressing, because the confusion is common. Routers are locked to the regulatory domain of the country they are sold into. Buying an American model does not buy you American spectrum.
The United States is on a different path
The American position was settled years ago and has not moved. The Federal Communications Commission adopted its 6 GHz order on 23 April 2020, making 1200 megahertz across 5.925 to 7.125 GHz available for unlicensed use.
Current American proceedings are still building on that rather than unpicking it. On 29 January 2026 the Commission adopted rules creating geofenced variable power devices in the U-NII-5 and U-NII-7 portions of the same 6 GHz band, allowed indoors and outdoors at higher power than earlier low-power devices. The direction of travel there is more unlicensed use, not less.
What it means if you are buying a router now
Nothing you buy today gets taken away. Regulatory changes of this kind apply to future assignments and future equipment authorisations, not to a router already certified and sitting on your shelf.
The practical advice is narrower than the headlines suggest. If you are buying in Europe, do not pay a premium for 320 MHz channel support on the assumption that more 6 GHz room is coming, because the advisory direction points away from that. Do check that a Wi-Fi 7 router includes a 6 GHz radio at all, since cheaper models in the generation drop it and sell the name without the band. A tri-band model such as the TP-Link Archer BE550 keeps the third radio and the wide channels that come with it, which is what makes the lower 6 GHz allocation usable.
If you are buying in the United States, the picture is unchanged and the full band remains available to unlicensed devices.
The dates that decide it
Two matter. European technical work on sharing and coexistence was set to report final results in November 2026, and the 2027 World Radiocommunication Conference will settle whether mobile gets 7125 to 7250 MHz. The fate of that disputed 160 MHz follows from the second.
Until then, the split stands as a recommendation to the European Commission rather than as law. A recommendation with this much industry weight behind it rarely reverses, yet it has not been implemented either, and that distinction is worth keeping straight.
