ZTE interference cancellation technology can increase uplink capacity by up to 40 percent for H3G Austria network

29 October 2012, Vienna, Austria - ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a leading global provider of telecommunications equipment, network solutions and mobile devices, has announced that its customer Hutchison 3G (H3G) Austria network has come in first placein comprehensive KPI tests that were recently conducted with all the operator networks in Austria by the European telecommunications publication, “Connect”. The H3G Austria network, which was modernized with RAN and core network equipment by ZTE, was placed in the top position, based on the excellent performance of the network.

H3G Austria has seen a year-on-year user increase of 24 percent in the last 12 months.  In addition, as mobile Internet applications grow in popularity, especially applications that rely on social networking services, there has been an increasing demand for the throughput capacity, upstream rate and response capabilities of the network.

To meet this demand, ZTE introduced the latest interference cancellation technology, significantly improving the uplink data transferrate and capacity. Network test results showed that ZTE’s technology enabled H3G Austria to offer an average rate of more than 50 percent faster upload speeds to customers compared with the second-place network. H3G Austria’s network also offers average download speeds of up to 11.7Mbps with ZTE’s technology.

The H3G Austria network was also praised in this test for its intelligent handset user experience, offering the highest successful network browse rate and the fastest webpage opening speed.

H3G Austria network has attributed its second consecutive win to the implementation of ZTE Uni-RAN and ZTE Uni-Core solutions. ZTE’s Uni-RAN solution helps operators to accomplish 2G/3G convergence, unified management and maintenance, resource sharing for different systems, and consequently cutting down TCO.ZTE’s Uni-Core solution supports the seamless evolution from 2G/3G packet core to evolved packet core, and assists operators in supporting unified 2G, 3G and 4G access. ZTE helps operators build a smart pipe that supports service differentiation and traffic distribution.

While H3G Austria users have grown rapidly in the last year, the uplink and downlink data flow of the packet data users has doubled, with the help of the ZTE Uni-RAN solution and the core network. The ZTE Uni-RAN solution enhanced the capacity and performance of the network, by applying ZTE's leading interference cancellation technology when ZTE and H3G Austria upgraded the whole network to the DC HSPA +. The application of interference cancellation technology eliminates the interference between the different users and as much as possible between the different channels of the same user. By increasing the signal noise ratio the uplink system capacity is increased, making the transmission data performance close to the industry maximum. In the case of certain high traffic sites, the increase in uplink can be up to 40 percent using this technology, making the network response faster.

“Recognising our customers’ needs, ZTE continues to introduce leading-edge technology to enhance network capacity and enable operators to provide high-quality networks. Last year we refreshed ZTE’s High-Speed Uplink Packet Access (HSUPA) speeds, at present  the application of interference cancellation technology can effectively improve network uplink capacity and enhance the end-user experience without changing the network terminal.The third-party evaluation of the Austrian H3G network has ranked number one for the second consecutive year, which confirms that ZTE has a strong technical capability to build world-class networks,” said Xu Ziyang, vice president, ZTE.

The ZTE Uni-RAN solution is used by 150 operators globally. In addition to the H3G Austria network, the broadband networks of China Unicom and Hong Kong CSL Limited have also been ranked number one in industry testing numerous times. To date, ZTE has won 38 LTE commercial contracts globally and has assisted some leading operators - such as Bharti Airtel, China Mobile, Hutchison, Softbank, Telenor, and CSL- in building 　LTE networks. ZTE has also partnered with more than 100 global operators to undertake LTE trials. In June 2012, ZTE and the leading multinational operator Hi3G Access AB won the Global Innovation Award for LTE Infrastructure, awarded to the company by media outlet, Global Telecoms Business, for their jointly constructed LTE FDD/TDD dual-mode network in Sweden.
