3G Wireless in Guatemala with EV-DO Solutions

Guatemala : Telefonica Moviles has launched its 3G mobile broadband services in Guatemala using CDMA2000 1xEV-DO technology from Nortel.

The new EV-DO high-speed network allows Telefonica to expand its subscriber services to include 'anytime, anywhere' access to a variety of services such as Web browsing and downloads of large video and music files at speeds comparable to wireline broadband connections like DSL. Telefonica also plans to offer its business customers secure mobile access to their corporate data networks from any wireless device, making it possible to remain productive when away from the office.

Telefonica Moviles Guatemala selected Nortel in May 2005 as the sole supplier of its advanced wireless broadband network in Guatemala.

"Nortel's technology and services have allowed us to modernize our network to provide the most innovative services to our subscribers in Guatemala," said Juan Antonio Abellan, general manager, Central America, Telefonica Moviles. "As one of the leading mobile services operators in the Spanish-speaking world, Telefonica is always anticipating the needs of the increasingly more sophisticated end-user, and we knew we could depend on Nortel's EV-DO solution to deliver on their expectations."

Telefonica Moviles new EV-DO network allows customers to download data on their mobile devices at speeds up to 2.4 megabits per second with average speeds of 300 to 500 kilobits per second - approximately 10 times faster than currently available networks. Such speeds also enable transmission of TV to an EV-DO enabled PDA. Nortel demonstrated this capability for Telefonica customers at a launch event in Guatemala City. Wireless operators around the world are beginning to use their existing networks to offer TV and other advanced video services that can include high-definition programming, video conferencing, remote surveillance and distance learning.

"We have worked closely with Telefonica in Guatemala to deploy a reliable and robust network that meets their needs and positions them as an innovative provider of mobile services to their subscribers in Guatemala," said Alvio Barrios, vice president, sales, Caribbean and Latin America, Nortel. "Nortel's EV-DO technology is designed to give wireless subscribers what they expect - fast and easy access to information and entertainment 'anytime, anywhere' to help enhance the quality of their lives."

Nortel supplies EV-DO equipment to 12 of the 21 operators across the globe currently offering commercial EV-DO service, including Verizon Wireless in the United States, Vesper in Brazil, Smartcom in Chile, Pelephone in Israel and Telstra in Australia. Nortel also provided EV-DO equipment to Eurotel for the first commercial 450 MHz EV-DO service in Eastern Europe. With its CDMA equipment designed to support 1xEV-DO through modular upgrades to existing hardware, Nortel re-uses existing base station equipment to help operators reduce or eliminate the need for costly hardware replacements.
