Vivo launches 3G over 1x EV-DO

27 Oct 2004

Brazil’s largest mobile operator Vivo has launched third-generation mobile services based on the CDMA2000 1x EV-DO standard over parts of its network in Rio de Janeiro and Sao Paulo. The infrastructure was provided by US equipment vendor Lucent Technologies, which spent the last few months installing 120 base stations to facilitate the launch. Vivo has also begun trials of 1x EV-DO services in Curitiba, Panana State, using equipment from Motorola. A 50/50 joint venture between European heavyweights Telefónica of Spain and Portugal Telecom, Vivo operates in 19 states as well as the Brasilia federal district, covering around seven million square kilometres. At the end of June 2004 it claimed 23.51 million subscribers, equal to 43.5% of the Brazilian mobile market.
