SÃO PAULO (WiMAX Day). The long-delayed auction of 3.5 GHz spectrum in Brazil may be extended well in to 2008, according to Plínio de Aguiar Júnior, the president of Brazil’s telecom regulator Anatel. Since the last delay in the auction process, the Court of Accounts in Brazil has contested the methods of pricing of the license fees and the exchange rates used, as well as whether to restrict bidding to companies who do not presently own licenses in the frequency band. The president of Anatel noted that the process now will require further studies, public consultations and approval from the regulator before any date can be set for the auction.
