du says it has completed the world's first commercial end-to-end connection over the upper 6 GHz band, a slice of spectrum regulators around the world are now studying as a candidate home for 6G services.

The UAE operator, formally Emirates Integrated Telecommunications Company, disclosed the milestone through Intelligent CIO this week. No contract value, vendor name, throughput figure or device used in the test accompanied the announcement.

What does "end-to-end" mean here?

du's phrasing points to a full network path — device through core — running on the upper 6 GHz band, rather than a lab-only link. The band itself sits between 6.425 GHz and 7.125 GHz and was the most contested agenda item at the World Radiocommunication Conference held in Dubai in late 2023.

What's the regulatory backdrop?

WRC-23 agreed to study the band under the ITU's IMT-2030 framework, the body's working name for 6G, alongside other candidate ranges. Europe and parts of the Arab world have moved faster than the United States, which reserved the upper 6 GHz for unlicensed Wi-Fi and has shown little appetite to revisit that call.

In the Gulf, the UAE's Telecommunications and Digital Government Regulatory Authority has historically followed European spectrum practice more closely than American, opening the door for du to test bands that US carriers cannot touch commercially.

Why does this matter for 6G?

The upper 6 GHz sits in the mid-band sweet spot — wide enough for fat channels, low enough to penetrate walls better than millimetre-wave frequencies that powered 5G's highest tiers. A single 200 MHz channel there behaves, roughly, like doubling the bandwidth a typical 5G mid-band cell carries today. That extra room is what 6G researchers expect to need for holographic communications, extended reality and always-on AI inference at the network edge.

du has staked its claim early. The operator ended 2024 as the UAE's second-largest mobile carrier by subscribers, behind Etisalat (now e&), and has leaned heavily on fixed-wireless access to differentiate. A live commercial U6GHz demonstration gives du a talking point as it pitches itself to hyperscalers and handset makers weighing early 6G device trials.

What we still don't know

The announcement names no vendor partner, no chipset supplier and no device. du has not said whether the link was over-the-air between commercial base stations, or used a fixed point-to-point link inside its network. Without those details, the gap between marketing claim and deployable service stays impossible to gauge.

What to watch next

The ITU expects to finalise IMT-2030 radio interface specifications in 2030, with first commercial 6G launches clustered around 2030 to 2032 in vendor roadmaps. Operators running live trials in candidate bands now are buying optionality — working relationships with regulators, equipment makers and standards bodies before the specification settles.

du's gambit is timing as much as technology. By moving before the band's status is final in the UAE, the operator positions itself to influence which direction the country's regulator tilts when the WRC-23 study period ends.

That positioning has limits: without public numbers on speed, coverage or device support, the trial remains a proof of concept in commercial packaging, not a measurable step toward 6G service. For a market that has consistently leapfrogged larger European peers on mid-band 5G rollout, even a thin announcement lands as a signal of intent — and a reminder that 6G's first commercial proving grounds will sit well outside North America.
