MINNEAPOLIS -- ADC (Nasdaq:ADCT; www.adc.com) announced today that Swisscom Mobile, Switzerland's leading wireless operator, has selected ADC's Metrica(R) Performance Manager software for its Universal Mobile Telecommunications Service (UMTS) network which is scheduled to be launched later this year. Swisscom Mobile has more than 3.7 million customers, covers 99.7% of the Swiss population and offers access to more than 370 mobile telephone networks around the world.

"We've had a very good experience using Metrica for our GSM and GPRS networks, and, most recently, the solution has given us the performance edge we need to help grow the largest wireless public LAN network in Europe and to enhance our Wi-Fi service," said Robert Marro, head of network performance management for Swisscom Mobile. "We believe that the technical superiority of the Metrica solution in terms of ease of maintenance, customization and administration, together with enhanced features such as the report writing facility, will provide us with the right level of flexibility and scalability to support a fast-evolving infrastructure such as our new UMTS network."

"Swisscom Mobile has a long history of providing reliable, high-quality services to their customers and we're pleased to be working with them," said David Heaps, senior vice president and general manager of the Metrica group of the Software Systems Business Unit for ADC. "By providing Swisscom with a next-generation performance management solution, we can support their business now and provide the flexibility necessary to adapt to future UMTS service requirements simply and cost-effectively."
