The network operator is Ericsson. The Swedish company has received permission from the German Federal Network Agency (BNetzA) to use frequencies from the 700 MHz band.
The dedicated Ericsson 5G mobile network allows live tests to be carried out under extreme network loads and at very high travel speeds. This facilitates the creation of test conditions hardly ever found in commercially operated live networks.
In addition to Ericsson, members of the consortium include the BMW Group, Deutsche Bahn, all three German network operators (Deutsche Telekom, Telefónica Germany, and Vodafone), the TU Dresden 5G Lab Germany, and the German Federal Highway Research Institute (BASt) and German Federal Network Agency.
The 5G test network was put into live by the the 5G-Connected Mobility consortium.
