Argentine cellco Movistar, part of the Spanish-owned Telefónica Moviles Group, has launched a 3.5G broadband service based on high speed downlink packet access (HSDPA) technology in Buenos Aires, reports BNamericas. The service enables high speed internet access from a laptop using a PC card. The company expects mobile broadband services to generate revenues of ARS5 million (USD1.6 million) this year and ARS50 million next, a company spokesman said, adding that the 3.5G network will be expanded to Córdoba, Mendoza and Rosario during 2008. Movistar expects its total investment in Argentina in 2007, which includes the deployment of the 3.5G network, to total ARS750 million. Movistar’s main rival, Telecom Personal, launched similar services in May this year.
