Motorola Proves UMTS Network Capability with Simultaneous Voice, Data Calls on Commercial 3G Handset


Motorola's Global Telecom Solutions Sector (GTSS) reached another significant milestone in its Universal Mobile Telecommunications System (UMTS) program as it successfully completed simultaneous voice and data, or Multi-Radio Access Bearer (RAB) calls on Motorola A830 UMTS handsets during a recent drive test for a major global operator. The ability to conduct simultaneous voice and data calls is a unique feature of UMTS technology, and this live demonstration of multiple RAB calls and other features and applications on a Motorola UMTS network provides a compelling testimonial to the reality of Motorola's UMTS solution capability.

Other key UMTS functionalities including soft handover, softer handover and power control were all successfully executed during the customer demonstration. All demonstrations were conducted in a live environment under drive test conditions and 3GPP Standard Release 99 version June 02 compliant.

"Feedback from the customer confirmed that the capability for simultaneous voice and data calls is an important differentiator for UMTS, " said Margaret Rice-Jones, corporate vice president and general manager of the Europe, Middle East, and Africa (EMEA) region for GTSS. "This demonstration, which featured the UMTS capabilities requested most often during our visits with customers worldwide, is fundamental proof that we can deliver a commercial UMTS network capable of supporting real and innovative services that operators need as they launch 3G networks."

Numerous Adaptive Multi-Rate (AMR) voice calls and data calls at 64Kps, 128Kps and 384Kps data rates were also completed during the drive tests. Subscriber applications including web browsing, packet video, downloading J2ME applets to play games and e-mail access also were used throughout the demonstrations to validate the service reality of Motorola's UMTS solution.

Motorola also demonstrated its UTRAN Pooled Resource feature that has been developed from its expertise in CDMA and is unique to Motorola CDMA and UMTS networks. This feature provides Motorola customers with an opportunity to lower the capacity investment required to meet unexpected busy call periods in their initial UMTS network. It allocates trunked capacity to the cell sector where it is most needed enabling the network to adapt to current capacity, coverage and quality demands while minimizing hardware requirements for the operator. In a subscriber "hot spot" scenario this feature can substantially reduce call blocking and help maintain quality of service.
