Vivo puts timeframe on GSM overlay

3 Jul 2006

According to Portugal Telecom CEO Henrique Granadeiro, Vivo will introduce GSM technology before the end of 2006. The anouncement follows reports last week that the cellco had begun discussions with vendors to determine the cost of an overlay project. According to TeleGeography’s GlobalComms database, Vivo is the fourth-largest CDMA-based operator in the world but is one of a number of companies recently declaring an intention to deploy a GSM network either alongside or in place of an existing CDMA network.
