Milpitas, California and Macau, China, November 12, 2007 ­ JDSU today introduced a specially designed edition of RoamerNet®, its managed service assurance solution for wireless network operators. The new exclusive offering allows wireless operators to test service performance at multiple Olympic venues in China months before hundreds of thousands of wireless subscribers travel to the games in Beijing next summer. RoamerNet helps ensure quality of service and protects valuable roaming revenue without requiring mobile operators to deploy fixed test and measurement assets.

JDSU has also introduced the "Mobile Service Assurance Kit," providing information on best test and measurement practices for wireless service assurance. The kit includes a new white paper, "Managed Automated Service Testing: Best Practices for Improving the Mobile User's Experience," which addresses cost-effective test approaches that can improve service performance and reduce customer churn.

The Beijing Olympics will take place in 37 venues across seven cities and attendance is expected to total more than half a million, including 500,000 visitors, 10,708 athletes, 70,000 volunteers, 17,600 press and 4,000 staff.  Mobile communications activity among these travelers will be intense as they text, phone home, conduct business, transmit photos and otherwise share their experience with friends, family and business associates. JDSU's RoamerNet allows operators to emulate subscriber experience, including roaming conditions, in any location in the world and to address network issues before they negatively impact their customers. 

"Quality of service is a critical business metric for mobile content service providers ­ this applies not only to monitoring service quality on the network but also the experience of customers roaming onto other operators' networks," said Patrick Kelly, senior analyst, OSS Observer. " As operators prepare their network for roaming subscribers visiting the games, JDSU's RoamerNet provides a cost-effective approach to managing service quality for a diverse set of services."

"It is critical that mobile service providers take steps to ensure service quality everywhere their customers go," said Jerry Gentile, general manager of JDSU's Service Assurance Solutions division. "RoamerNet gives operators the ability to gauge and assess service performance metrics that ultimately determine a wireless subscriber's quality of experience. Wireless service providers need to take action now in order to make sure their networks are ready for the games next summer."

JDSU will showcase its wireless service assurance solutions, including RoamerNet, at a number of upcoming industry events, including:

• GSMA Mobile Asia Congress, Macau, China, November 12-15, 2007 (JDSU booth #K02, Hall D)
• GSMA Mobile World Congress, Barcelona, February 11-14, 2008 (JDSU booth #2B97, Hall 2)
