Following the auction of frequencies for wireless access that concluded in May 2010 and led, inter alia, to the award of frequencies from the so-called digital dividend (800 MHz band), and pursuant to an undertaking it gave to the EU Commission, the German NRA BNetzA has opened a hearing on the amount and distribution of frequencies held by the four GSM and UMTS operators in Germany, with a view to determining whether the frequency distribution amongst the operators lead to distortion of competition. The hearing implements Art. 1 para 2 of the revised GSM Directive 87/372/EEC pursuant to directive 2009/114/EC and comments by stakeholders can be submitted until 11 October 2010.
