Business Wire, April 4, 2005

PISCATAWAY, N.J. -- Recognizing the business and operational challenges that mobile operators face, Telcordia Technologies, Inc., the leading provider of telecommunications software and services, has applied its technological innovation and know-how to develop Telcordia(R) Auto RF, a state-of-the-art solution that ensures a wireless network is working at its peak performance all day, everyday; resulting in increased capital efficiency, quality of service and customer satisfaction. E[acute accent]MetroPCS, a provider of wireless communication services, is the first to purchase Telcordia Auto RF and has already deployed it in their San Francisco, CA market. In doing so, MetroPCS has increased their call handling capacity in the San Francisco Bay area without adding networking equipment.

market demand without spending more money," said Terry Vega, president, Wireless, Cable & Emerging Markets (WCEM), Telcordia. "That's a tall order but one that Telcordia is already helping our customers meet by helping them maximize their operational efficiency and one that MetroPCS is already delivering with its flat rate, unlimited wireless service."
