Lucent Technologies announced today that it has successfully completed interoperability testing of its third generation (3G) Wideband-Code Division Multiple Access (W-CDMA) systems with several key suppliers of W-CDMA equipment in China, including Alcatel, Motorola and Zhong Xing Telecommunications (ZTE) and Huawei. These successful tests highlight the readiness of Lucent's W-CDMA equipment for commercial deployments in China and other markets.

The testing program involved compatibility tests between Lucent's W-CDMA radio access networks (including Lucent's Flexent OneBTS base station) with core network solutions from the other participating suppliers. Additionally, Lucent's core network solution was tested with the other suppliers' radio access networks. In the course of the testing, Lucent successfully established circuit and packet connections, completed multiple, simultaneous voice calls, conducted high-speed data calls and delivered SMS (short message service) two-way text messages. The tests also included the demonstration of roaming between 2G and 3G networks, and verified support of a variety of critical mobility and security features.

"These successful tests demonstrate that Lucent's W-CDMA systems meet Chinese operators' requirements for multi-vendor compatibility, and also address their reliability and performance needs," said Roger Derrien, vice president for W-CDMA product management with Lucent's Mobility Solutions Group. "Our W-CDMA customers can now deploy mobile networks using equipment from multiple vendors with complete confidence that those systems will work together seamlessly."
