CTI Movil Expanding GSM Network in Argentina with Nortel Solutions

BUENOS AIRES, Argentina--(CCNMatthews - Sep 22, 2005) -

CTI Movil, Compania de Telefonia del Interior S.A., a subsidiary of America Movil (BMV:AMX)(NYSE:AMX)(Nasdaq:AMOV), is continuing to expand its GSM wireless network in Argentina using wireless broadband solutions from Nortel (NYSE:NT)(TSX:NT) to offer improved wireless coverage and additional services.

Phase one of the network expansion, involving addition of 360 base stations, started late in 2004 and is now complete and in service. Phase two, already underway, will add 136 new base stations, enabling CTI Movil to offer customers in the interior regions and rural areas of Argentina the same quality and breadth of mobile services that are available in metropolitan areas.

Besides GSM access equipment, Nortel is also providing CTI with related Wireless Network services.

The CTI Movil network in Argentina uses EDGE (Enhanced Data for GSM Evolution) 3G wireless technology, enabling enhanced data services like wireless Web browsing, e-mail, downloading of ring tones, and games.

"Nortel works with customers throughout Latin America to deploy, maintain and evolve the advanced infrastructures that allow these operators to offer multiple services, while helping them reduce operating costs," said Ricardo Casal, managing director, Southern Cone, Nortel. "This latest project with CTI reinforces Nortel's position as one of the main providers of advanced wireless networks in the Southern Cone, where we're committed to helping regional operators enhance the communication experience of their customers."

Nortel wireless broadband technology is designed to maximize existing customer investments and to help service providers drive down capital and operating costs. Nortel equipment migrates to broadband mobile technologies through modular upgrades. This approach re-uses existing base station equipment to reduce or eliminate the need for costly hardware replacements.

Nortel has designed, installed and launched more than 300 wireless networks in over 70 countries across the globe. Nortel was the industry's first supplier with wireless networks operating in all advanced radio technologies, and is the only end-to-end provider of all next generation wireless solutions.
