Schema`s Maxima Mentor Now Compatible with All Leading CDMA Vendors

HERZLIA, Israel – March 12, 2007, Schema, a leading global provider of network optimization software solutions, announced today that Maxima Mentor, the first CDMA and EVDO optimization solution based on actual network usage, is now compatible with all major CDMA equipment vendors: Nortel, Motorola, and Lucent. Combined, these three vendors account for almost two-thirds of the global CDMA market, and over 80% within the United States. This strengthens Schema`s position in the American market and enables the majority of operators to improve network performance and user experience while reducing OpEx and CapEx. Since its initial launch less than a year ago, an increasing number of CDMA/EVDO operators have already deployed Maxima Mentor, validating its revolutionary approach to network optimization. Rather than relying on costly drive tests and lengthy data compilations which only provide a partial and estimated network view, Maxima Mentor provides operators with an accurate view of their entire network and service quality, including in-building coverage, by using live data generated from subscribers` handsets. Maxima Mentor proactively sustains network performance and, as a result, increases network MOU and ARPU, reduces operational costs and capital expenditures, and increases customer satisfaction. “Maxima Mentor is the first wideband network optimization product that turns information from subscribers’ handsets into real knowledge that helps maintain network utilization at optimal levels, saving CDMA/EVDO operators significant time and reducing both OpEx and CapEx,” said Avshalom Ben-Zoor, Schema`s VP Marketing. “Having a near real-time picture of the network rather than a prediction or just a sample of the network helps operators maximize network performance and customer experience. Maxima Mentor enables operators to optimize their networks more easily and more frequently, yielding ongoing improved call quality, diminished dropped and blocked calls, and reduced churn.” Maxima Mentor streamlines the complex and time consuming maintenance and troubleshooting processes by automatically providing solutions to problems identified in the Radio Access Network (RAN). As subscribers move around the network and make use of their mobile handsets, mobiles are constantly engaged in complex interactions with the network that generate specialized quality of service reports that reflect the customer experience. Schema’s Maxima Mentor analyzes this information and provides clear recommendations to optimize RAN parameters such as antenna tilts, power and neighbor lists. Network engineers can then implement these changes automatically and assure long-lasting peak network quality. Product demonstrations will be available at Schema`s booth, located in Hall 3, #1873 at the CTIA Wireless 2007 event in Orlando.
