Chile’s Supreme Court has heard the opening arguments in relation to a dispute over whether existing mobile operators should be allowed to participate in the forthcoming auctions of 3G licences, writes BNamericas citing local daily the Diario Financiero. In July, the antitrust commission FNE and the telecoms regulator Subtel appealed a decision by the antitrust tribunal that would not allow for a large portion of the spectrum to be reserved for a new, fourth mobile operator. Of the 45MHz available, Subtel had hoped to reserve some 30MHz for a new operator which would focus mainly on providing value added services. The country’s three existing operators – Entel PCS, Movistar and Claro – would then be allowed to compete for 5MHz each. The FNE argues that the existing operators should not be allowed to participate at all as they have sufficient spectrum already.
