Deutsche Telekom may follow suit.
Germany was scheduled to hold the 5G auction by the end of March and was expecting to raise up to €5 billion.
The key items on the terms issued by the Federal Network Agency being contested are concerning the coverage requirements, especially the coverage in rural areas and along motorways, and the mandated network sharing with competitors (the so-called domestic roaming).
Telefónica Deutschland argued that the coverage obligations could not be fulfilled with the spectrum at auction, while the frequency in its possession is already being used by other expansion requirements.
It must be in the interest of all involved that clarity and planning security are created here before an auction,” said Markus Haas, CEO of Telefónica Deutschland.
Telefónica was also unhappy that politicians should demand network sharing between competitors.
