Spirent plc: Spirent unveils diagnostic monitor for WCDMA



CANNES, France, Feb 18, 2003 (M2 PRESSWIRE via COMTEX) -- Spirent Communications will be demonstrating its Universal Diagnostic Monitor (UDM) for WCDMA applications at the 3GSM World Congress in Cannes (Booth D19). Spirent`s UDM allows monitoring and analysis of terminal and network performance, independent of air interface technology (WCDMA, GSM, CDMA2000).

Spirent`s UDM automates simultaneous test control and data collection for WCDMA mobile devices. UDM is unique in its ability to monitor key aspects of a mobile` s performance and simultaneously automate control of the mobile. This capability also enables highly automated closed-loop performance testing when integrated with a Spirent performance analysis system, such as the U-ATS UMTS Automatic Test System. The UDM has been developed using Spirent`s Universal Tool Suite (UTS) architecture, which is air-interface-technology and chipset-independent. Support is provided for chipsets from QUALCOMM and PrairieComm in this initial release.

"By building upon our leadership in the CDMA2000 test arena, we are able to offer stable and mature test applications to the WCDMA market," said Charles Simmons, president of Spirent Communications` Wireless division. "Built on a well-established platform, the UDM allows WCDMA handset manufacturers and test labs to monitor a UE`s performance while controlling it in real time, helping to qualify 3G mobiles for market faster."

The Spirent UDM is a full-featured Diagnostic Monitor that allows developers, field and drive test teams, certification test teams and service providers to monitor and analyse the performance of UMTS mobile devices and networks. The UDM`s capabilities far exceed those of conventional DMs, enabling connection to multiple UMTS devices and software applications simultaneously. This feature allows direct, side-by-side evaluations of UMTS devices for detailed performance comparisons.

Spirent Communications` wireless test solutions aid in all phases of mobile handset development and deployment for the world`s leading chipset, handset and infrastructure manufacturers and mobile service providers. Spirent is considered by the industry the "one-stop-shop" for CDMA handset performance and certification testing. Among its other accomplishments, Spirent has introduced the first and only integrated solution available to test location-capable CDMA phones, a critical element of assisting manufacturers in meeting the US FCC E911 requirements. Spirent has leveraged its success in mobile performance and certification testing to also bring comprehensive performance analysis to the WCDMA market.
