Costa Rica’s comptroller and attorney general have given telecoms regulator Sutel the green light to go ahead with an auction for mobile spectrum after completing a probe into a suspected conflict of interests regarding one of the potential bidders, notes TeleGeography. Sutel postponed the publication of bidding rules on 5 February for the auction of spectrum blocks in the 850MHz, 1800MHz and 2100MHz bands for ‘logistical’ reasons. Each of the three blocks will amount to 60MHz. Telefonica, Cable & Wireless, Millicom, Digicel and America Movil have all expressed interest in participating in the tender.
