Chilean telecoms regulator Subtel has extended the date for receiving and opening bids for 3G licences by five days, to 20 July writes BNamericas citing Subtel. The long-anticipated auction of UMTS concessions was launched in April, with bidding rules on sale until 30 June. In accordance with a Supreme Court ruling on 27 January, existing wireless players can participate in the spectrum auction, but if any company surpasses the 60MHz limit it is obliged to return some of its spectrum in other bands to the state. The three existing operators in the country are at or close to the limit: Entel PCS already has 60MHz, while Movistar and Claro have 55MHz each. Subtel has expressed that the intention of this measure is to allow a fourth operator to enter the market and focus expressly on offering 3G services.
