In August 2011 the Hungarian Media and Communications Authority started an auction for the sale of EGSM frequency bands, enabling a fourth mobile radiotelephone network in Hungary in GSM and UMTS bands. The current three MNOs and a state-owned consortium were among the bidders for these frequency bands. On 30 January 2012 the authority announced that the winner of the auction was the consortium of Hungarian Post, Hungarian Development Bank and the Hungarian Electricity Works. They promised to start a 4th mobile network service by the end of 2012 (first in the capital only, and in two years time for all major towns and roads). The three MNOs were also granted smaller frequency blocks. The incumbent MNOs have challenged the decision of the court. The court's final and binding judgment on 17 September repealed the authority's decision on two grounds. The more important basis for repeal was related to the "voluntary" undertaking by the incumbent MNOs to provide roaming for the fourth MNO. As part of the bidding documentation, the incumbent MNOs were required to agree to this roaming obligation in order to be able to bid for the smaller frequency blocks (thus, the NRA called this undertaking voluntary). There is no concrete information yet as to whether a new procedure will be initiated at all and if so when.
