(SIE.FK) Brazil: Siemens Sets Up GSM/EDGE Mobile Radio Network for Telecom Americas

MUNICH, Germany–(BUSINESS WIRE)–June 9, 2003–

Company Constructs the Largest Part of the Mobile Radio Network –

Third EDGE Order

In Brazil, Siemens (NYSE:SI, FWB: SIE) is setting up a GSM/EDGE mobile radio network for Telecom Americas, a subsidiary of America Movil, one of the largest mobile operators in Latin America. The order was placed with the mobile communication group of Siemens AG – Siemens mobile for short – and encompasses the GSM mobile network around the metropolis of Sao Paulo and other Brazilian states. In addition, EDGE is being installed: a transmission technology for data services with high capacity requirements. It is the third EDGE order for this Siemens Group.

Siemens mobile is delivering transmit and receive stations as well as microwave systems for the GSM1800 network of Telecom Americas and is equipping them with EDGE technology. Based on the GSM standard, EDGE (Enhanced Data rates for Global Evolution) provides data transmission rates that are more than 40 times higher than GSM. This makes it possible to send videos, music clips, and photos via mobile devices; customers can also use interactive games and location-based services.

“Our goal is to be among the three strongest GSM suppliers in Latin America. This order will take us one step closer to that goal”, explains Joe Kaeser, board member of the Siemens Information and Communication Mobile Group. “Since June 2000, when the government decided in favor of GSM1800, we have been present in the Brazilian market and have been able to expand our business steadily since then. The most recent decision of the government to continue using the 3G frequencies for the succeeding generations of GSM is a confirmation of our strategy. We’re proud to demonstrate the efficiency of our powerful EDGE technology now for the first time also in South America, besides the projects in USA and Asia.”

Telecom Americas has GSM licenses for all the important regions of Brazil, including Sao Paulo, and has more than 6.2 million customers. In the metropolitan area of Sao Paulo alone, there are 18 million potential mobile device users.
