The Brazilian telecoms regulator Anatel has officially cancelled its planned auction of WiMAX spectrum in the 3.5GHz and 10.5GHz bands, reports BNamericas citing a statement from the watchdog last Friday. In total, 101 bidding groups were consulted on the matter, Anatel said, of which around 80 supported its plan to cancel the process. Eight groups objected to the cancellation while 13 did not offer up an opinion. The main reason for the decision was the outdated minimum prices of 3.5GHz spectrum, it said. The bidding rules were published in July 2006, in accordance with telecoms rules in force at the time.
