Europe is preparing a major spectrum decision in the upper 6 GHz band. The choice will affect mobile networks, Wi-Fi, and apartment connectivity. Fiber may enter a building, but users finish the journey wirelessly. That final link now drives a heated policy debate.
The GSMA argues that mobile operators need priority in this band. Its case centers on future capacity. Luiz Felippe Zoghbi said 6G will need 200 MHz channels per operator at launch. Later, that requirement could rise to 400 MHz.
With three operators in many markets, 600 MHz becomes a starting point. That makes Europe’s proposed 540 MHz allocation look tight. “If it’s only 540, yes, Europe would be behind,” Zoghbi said.
However, the debate does not end with mobile demand. Wi-Fi carries huge indoor traffic today. Homes, offices, hotels, and apartment blocks rely on it heavily. Managed Wi-Fi providers also use wide channels in dense buildings.
The GSMA responds with another argument. It says Wi-Fi’s biggest limit is not spectrum. Instead, it points to slow equipment upgrades. Many users still run Wi-Fi 4 and Wi-Fi 5 devices. Newer Wi-Fi 6E and Wi-Fi 7 systems remain less common.
“The biggest bottleneck for Wi-Fi is the ability to upgrade to a newer technology,” Zoghbi said.
That claim matters for regulators. If better devices solve Wi-Fi congestion, mobile gains a stronger claim. Yet city-wide averages can hide dense apartment realities. Professionally managed buildings may adopt new Wi-Fi faster than consumers.
Indoor mobile coverage also remains a serious question. The GSMA says 70% to 80% of mobile data is consumed indoors. It also says mid-band spectrum carries much of that usage. Still, apartment walls, elevators, and concrete can weaken signals sharply.
This creates a practical challenge. A macro mobile network may not reach every flat reliably. Building owners may still need indoor systems. Tenants may still depend on Wi-Fi for stable service.
Regulators are taking different paths. The EU’s RSPG supports mobile priority for 540 MHz. It may later expand access toward 700 MHz. The UK has chosen a more complex approach. Ofcom will allow Wi-Fi first, then mobile in defined areas.
“There is no guarantee that Ofcom is going to go beyond 540,” Zoghbi said.
Money adds another layer. Operators face pressure to fund new networks carefully. The GSMA wants lower spectrum prices and cheaper renewals. High auction costs could reduce investment in actual infrastructure.
For apartment owners, the central lesson is clear. New spectrum alone will not solve indoor coverage. Mobile and Wi-Fi must both work inside real buildings. Policymakers need data from those environments, not only city averages.
