New Orleans, Dallas and Campbell, Calif. -- March 18, 2003 -- Marconi (MONI), through its Wireless Business Unit, and SnapTrack®, Inc., a wholly owned subsidiary of Qualcomm Incorporated (Nasdaq: QCOM) and pioneer of Assisted Global Positioning System (A-GPS) location systems, announced today an agreement to cooperate in the development of an enhancement to Marconi's Planet EV tool, the next-generation version of its leading network planning and optimization product family. The two companies are cooperating to empower Planet EV with its newest module, the Base Station Almanac (BSA) Planner. The module will improve the accuracy and efficiency of the deployment and maintenance processes for Qualcomm's gpsOne™ hybrid A-GPS location systems for mobile phones and other wireless devices and optimize overall performance and accuracy of the gpsOne system, the world's most widely deployed precision location technology for mobile handsets.

The rapidly expanding location services market includes personal navigation and mobile directory assistance services, sales force management, corporate asset tracking and coordination, "friend finder" and child or pet tracking services, location sensitive billing, location-enabled entertainment, and enhanced fleet management. Location services will enhance public safety for people placing emergency calls on their cellular phones by helping emergency officials rapidly and precisely respond to a crisis or call for help.

"We are very pleased to be working with Marconi to provide this powerful BSA generation capability to the wireless community," said Dr. Kamil Grajski, general manager of SnapTrack. "This tool will allow carriers to more quickly and efficiently create and maintain accurate BSAs, and ultimately deliver optimized location performance to their customers for E911 emergency location calls and for location-based services."

The BSA Planner solution will automatically generate an initial Base Station Almanac, and will provide maintenance and updates of the BSA by incorporating data and information from Planet EV and other carrier network planning and maintenance tools and resources. Using Planet EV, operators will also be able to obtain real-time performance information from Mobile Switching Centers (MSCs), which helps synchronize the BSA with actual network configuration information as it changes from day-to-day. In addition, the new tool will help improve the hybrid aspects of gpsOne performance by providing accurate, up-to-date network configuration, base station geometry and RF environment information to SnapTrack's SnapSmart™ Position Determination Equipment (PDE), when calculating a mobile's position.

"This key enhancement to our planning and optimization portfolio is a critical component in providing a complete and effective network solution in the E911 and LBS space," said Chip Wagner, head of Marconi's Wireless Business Unit. "Furthermore, it demonstrates the flexibility and openness of Planet EV's architecture for the integration of other industry products and data that complement and augment our solutions. We are very pleased to be able to deliver a tool that will improve crucial service performance, while cost-effectively opening the door to additional revenue opportunities."

About gpsOne
With over 10 million gpsOne-enabled mobile phones sold to date, Qualcomm's gpsOne solution (featuring SnapTrack technology) offers robust location data availability under the most challenging conditions, whether in concrete-and-steel high-rises, convention centers, shopping malls or urban canyons. Using a hybrid Assisted-GPS approach that utilizes signals from both the Global Positioning System (GPS) satellite constellation and CDMA cell sites, the gpsOne solution enhances location services availability, expands terrain coverage, accelerates the location determination process, and provides better accuracy for callers, whether during emergency situations or while using GPS-enabled commercial applications. gpsOne protects privacy with its built-in Location at Hand™ feature, allowing users to control their location information in most commercial implementations. gpsOne is supported for IS-95/CDMA2000 and GSM/GPRS/UMTS.
