SÃO PAULO (WiMAX Day). Last month the president of GSM operator TIM Brazil, Mário César de Araújo, issued a statement that telecom regulator Anatel should no longer delay the auction of WiMAX spectrum. Araújo also revealed this week that the company had planned to invest US$1 billion this year in spectrum acquisition and network construction for WiMAX and 3G. This amount is part of a planned budget of just over US$3 billion through 2009 for WiMAX and 3G investments for the Brazilian subsidiary of Telecom Italia.
