(Telecompaper) Germany's Federal Network Agency (BnA) is looking to raise billions of Euros from a new auction of mobile spectrum, reports the 'Frankfurter Allgemeine Zeitung' newspaper. This will include spectrum already used by network operators Deutsche Telekom, Vodafone, E-Plus and Telefonica for voice and data communications, as well as 700 MHz 'Digital Dividend IUI' frequencies previously used for radio and TV. The network operators' licences for the spectrum they already use are due to expire in 2016. The plans are opposed by broadcasters and state media authorities, which insist that the 700 MHz spectrum is vital for guaranteeing delivery of DVB-T services. Meanwhile, the mobile network operators want the regulator to simply extend their GSM frequency licences without an expensive auction, as they are faced with falling revenues and network expansion costs.
