Together with project partners Deutsche Bahn, Ericsson and Vantage Towers, the operator has started building a network along a test track.
The German company says it will launch its own network on December 8th.
Vodafone says it has built over 225 new mobile masts since the start of the year.
The operator is launching what it calls “5G Plus” on October 10th.
The project is part of a €8.1 billion EU initiative to fund the development of microelectronics and communication technologies.
For the test Telekom equipped a rooftop location in the town of Alzey in Rheinhessen with a 6 GHz antenna. In addition, an antenna was mounted that is already used today for the 5G mobile communications standard and transmits via the 3.6 GHz frequency band.
The operator has been selected by Eurogate Terminals to build the networks.
The operator says it now reaches 74 million people with its 5G network.
The German mobile operator is set to launch its own network in the coming months.
The company says it has achieved its year-end coverage target ahead of schedule.
