JDSU RoamerNet Managed Service is Certified for Ensuring Mobile Service Quality for Operators Worldwide MILPITAS, Calif., Sept. 7 /PRNewswire-FirstCall/ -- JDSU (Nasdaq: JDSU; and TSX: JDU) today announced that its managed service for mobile operators, RoamerNet, has received the Global Roaming Quality (GRQ) certification from the GSMA. JDSU RoamerNet monitors the quality of mobile voice and data services while roaming across service provider boundaries, and is currently deployed by mobile operators around the world. The GSMA, which is widely recognized as representing the interests of the worldwide mobile communications industry, certifies roaming monitoring providers for GRQ through a rigorous certification process which documents measurement methods and verifies they are made in accordance with GSMA procedures. JDSU will be exhibiting its portfolio of test solutions and services at Broadband World Forum 2009 in France, September 7-9, booth #621. "JDSU is honored to have received such a distinguished certification in the industry from the GSMA. This underscores the success of RoamerNet at building confidence among operators that the mobile services they deliver, such as Smartphone, EDGE, 3G, HSDPA and USDPA, are of impeccable quality," said David Opsahl, vice president of Global Services, JDSU Communications Test and Measurement business segment. The GSMA GRQ certification is an important endorsement for mobile operators who are turning to managed solutions and want to ensure that their roaming services are being verified by an independent monitoring service of the highest quality. RoamerNet managed services can be deployed quickly and easily to help operators verify service quality without building or maintaining their own monitoring infrastructure. This helps them reduce capital expenditures and drives their ability to introduce new services faster and more cost-effectively.
