Brazil's Vivo to Delay CDMA Network Shut-Down

Note -- this news article is more than a year old.

Brazilian mobile network Vivo has announced that it is delaying the shut down of its CDMA network until the end of June 2012. The network had been due to close down next month based on an announcement made in March this year.

The company said that it would delay the shut-down as it still has 2.3 million customers on the older network and wanted to prevent disruption to its customers.

The company originally announced its migration from CDMA to GSM in June 2006 when it said that it would build a GSM overlay on its existing network infrastructure. CDMA coverage in the South, the interior of Sao Paulo and a piece of the Midwest was provided by Motorola. The rest of Brazil was divided between Nortel and Alcatel-Lucent.

The network is currently reported to be filling in gaps in the GSM coverage where CDMA services are currently the only option.
