Deutsche Telekom carried 57.7 terabytes of data across its mobile network during the first weekend of this year's Oktoberfest in Munich, a record for the event and an 18 percent increase on the same weekend last year.

The German operator also reported a milestone in technology mix: 50.9 percent of that traffic ran over its 5G network, up from 40 percent a year earlier. This is the first Oktoberfest opening weekend in which more than half of Deutsche Telekom's event traffic moved over 5G rather than 4G.

Oktoberfest has long served as a stress test for German mobile networks. The festival grounds on the Theresienwiese concentrate several hundred thousand visitors at a time into a compact area, generating traffic densities that ordinary urban network planning rarely produces. Operators typically add temporary capacity and densify cell sites ahead of the event each year, and the traffic figures they publish afterwards offer a rare, directly comparable annual snapshot of how demand and 5G adoption are evolving in Germany's most crowded venue.

The 18 percent year-on-year growth in total traffic points to continued strong increases in per-user data consumption, driven largely by video streaming, social media sharing and messaging during the event. The jump in the 5G share from 40 percent to 50.9 percent reflects two parallel trends: the growing number of 5G-capable handsets in circulation among German consumers, and the expanding coverage and capacity of Deutsche Telekom's 5G footprint, which now carries the majority of traffic in dense-venue conditions for the first time at this event.

For Deutsche Telekom, the figures serve as proof point for its network investment strategy. Carrying a record volume without reported congestion issues supports the operator's positioning on network quality in the German market, where it competes against Vodafone Germany and Telefónica's O2 Germany for both consumers and the network-quality narrative that German subscribers, unusually among European markets, still weigh heavily in their choice of operator.

The numbers also carry commercial weight beyond marketing. Dense-venue performance is a key selling point in enterprise and wholesale discussions, and event traffic statistics feed into capacity planning for the coming year. An 18 percent annual traffic increase at a single venue, sustained over multiple years, is the kind of compounding demand curve that shapes operators' spectrum and densification decisions.

Deutsche Telekom did not break down the traffic by application or provide per-user figures in its announcement. The company also did not disclose the split between the festival's temporary network infrastructure and its permanent surrounding sites.

The figures cover only the first weekend of the festival. With Oktoberfest running for roughly two weeks in total, the full-event traffic total will be substantially higher, and Deutsche Telekom is expected to publish cumulative figures once the festival closes.
