[ZTE announces world's first EV-DO Revision B VoIP Call on its CDMA2000 system achieving 9.3 Mbps on the downlink and 5.4 Mbps on the uplink.]

Shenzhen, China -- ZTE Corporation ("ZTE"), a leading global provider of telecommunications equipment and network solutions, today announced another technological breakthrough by achieving the world's first EV-DO Revision B (Rev.B) VoIP Call on its CDMA2000 system, marking the first time in the industry that a CDMA vendor achieves an impressive 9.3 Mbps download rate and 5.4 Mbps upload rate. This remarkable feat once again demonstrates ZTE's leading position in the CDMA industry. The excellent results were announced by the company in the recently concluded 3GPP2 Standards Conference 2009 held in Shanghai, China from February 16-24, which was jointly organized by ZTE and China Telecom to promote next-generation wireless broadband communications.

ADVERTISEMENT EV-DO is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. It was designed as an evolution of the CDMA2000 (IS-2000) standard that would support high data rates and could be deployed alongside a wireless carrier's voice services. It is standardized by 3rd Generation Partnership Project 2 (3GPP2) as part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers worldwide, particularly those previously employing CDMA networks.

"In order to meet customers' demand in addressing advanced network evolution, we launch the world's first EV-DO Rev.B technology several months ahead of our rivals," said Li Jian, General Manager of CDMA Products, ZTE Corporation. "We are committed to the industry and continue to invest and speed up large-scale commercial use of EV-DO Rev.B to leverage telecom operators' investment in EV-DO Rev A networks."

The company has completed the first stage of achieving EV-DO Rev.B and adopted 3-carrier bundling technology, with each carrier having a bandwidth of 1.25 MHz. Compared with mature commercial EV-DO Rev.A, what ZTE's EV-DO Rev.B does is to only upgrade EV-DO Rev.A's software, with no additional hardware equipment required. Both ZTE's EV-DO Rev.A and Rev.B adopt identical baseband chipset.

ZTE plans to commercialize its EV-DO Rev.B system in Q3 2009, reaffirming its leading position in EV-DO technology development.

In future, EV-DO Rev.B can bundle up to a maximum of 15 carriers, with a download (forward) rate of 73.5 Mbps and an upload (reverse) rate of 27 Mbps. Among the unique features of EV-DO Rev.B include allocating flexible bandwidth and offering better QoS, hence enhancing user experience.
