du has switched on the upper 6 GHz band for paying customers on its live mobile network in the UAE, claiming a world-first it says anchors its 5G-Advanced and 6G roadmap. The operator, formally Emirates Integrated Telecommunications Company, put out the announcement this week with no companion numbers.

No subscriber count, coverage map or named device partner arrived alongside the headline. That is the sort of detail a deployment claim normally carries. du has offered a milestone, not a market.

The band in question sits between 6425 and 7125 MHz. It is the upper slice of the 6 GHz range, sitting above the lower 6 GHz frequencies that regulators from the US to Saudi Arabia have already opened for licence-exempt Wi-Fi 6E and 7 use. The mobile industry's claim on it is the live spectrum fight of the moment.

What does U6GHz actually buy an operator?

Roughly 700 MHz of contiguous spectrum. That is more than double what most mid-band 5G operators can scrape together from the 3.5 GHz band. Capacity is the prize, not coverage: more megahertz per cell means more throughput in dense urban corridors, malls and stadium clusters where du's rivals have publicly wrestled with congestion.

du's claim is a deployment, not yet a standard. The 3GPP has not finalised upper-6 GHz radio specifications; Release 19 and 20 carry the work. Without chipsets and commercial handsets, what du has lit up is closer to a proof of concept than a product line.

Where does the regulator stand?

The UAE's Telecommunications and Digital Government Regulatory Authority has historically been permissive on spectrum experiments, particularly when home-grown operators frame the work as feeding international bodies. du is effectively arguing that a live network, however small, gives it more weight at ITU-R meetings than a paper submission would.

Globally the picture is messier. WRC-23 in Dubai declined a full IMT identification for the upper portion of the band, kicking the question to WRC-27 in 2027. Several Arab and African administrations pushed hard for identification at the 2023 conference and lost. They now have a working reference site to point at, courtesy of du.

The du angle

du has spent the past two years positioning itself as the UAE's 5G-Advanced first mover, ahead of market leader e& on standalone core rollouts and network slicing trials. An upper-6 GHz live network fits that script rather neatly. Whether any of it reaches consumer handsets before 2027 is a separate matter, and one du has not addressed on the record.

The marketing dividend is not negligible either. "World-first" headlines travel well across regional press cycles, and du's enterprise sales team will recycle them into every RFP response for the next 18 months.

What to watch next

Three signals will tell readers whether this is a genuine milestone or a press release with a working base station:

• A named chipset or handset partner inside six months.
• A TRA commercial licence for the band, rather than an experimental authorisation.
• A throughput number that survives independent testing by the likes of Ookla or Speedtest.

Two of those would make the claim stick. The third milestone is WRC-27 in 2027, where du's live deployment will almost certainly be cited inside the IMT identification arguments the UAE delegation will need to win.
