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.
In Alzey, Deutsche Telekom tested using 400 MHz in the 6.425-7.125 MHz range. A previous 6 GHz test took place in Bonn in October 2022. There, Deutsche Telekom wanted to test the upper-6 GHz frequency’s suitability for inner-city areas.
This time around they used carrier aggregation to combine two bands. The devices bundled different frequency bands for more bandwidth and enabled higher data rates. As part of usual network modernisations, the 6 GHz band could then additionally go into operation at Telekom’s 5G mobile sites.
“The 6 GHz spectrum has the characteristic to meet the growing demand of our customers for more capacity and more speed. That is why we hope that the World Radiocommunication Conference will set the direction for mobile radio use,” said Abdu Mudesir, Head of Technology at Telekom.
