ZTE and Qualcomm Boost UMTS Uplink by up to 60%

Qualcomm and ZTE have collaborated to significantly enhance the capacity and performance of UMTS systems with the integration of Qualcomm's Uplink Interference Cancellation (ULIC) technology into ZTE's next-generation UMTS base station products.


The companies claim this technology will enable operators can boost their UMTS data throughput by up to 60 percent and deliver a user experience that is comparable to LTE in a similar channel bandwidth. The technology also enables UMTS operators to increase voice capacity by up to 45 percent.


Specifically, ULIC technology can deliver improved system capacity by eliminating interference from multiple uplink data streams. Enabled by the increased level of integration possible in today's commercial chips, ULIC brings the performance of CDMA-based modems close to their theoretical limits. The design is scalable and supports cancellation for a large number of simultaneous users and transmissions on the uplink.


"ZTE serves the world's top mobile operators based on our ability to consistently deliver high-quality and high-capacity network performance," said Zhang Jianguo, general manager of ZTE's UMTS products. "Our ongoing relationship with Qualcomm has enabled us to commercialize leading edge technologies that bring value to the entire wireless ecosystem. Using ULIC technology, we are providing operators with a highly efficient means to optimize their system performance while also extending the lives of their existing networks."


"Interference cancellation is helping to redefine the performance characteristics of UMTS by improving system capacity and delivering data throughput that is on par with LTE networks," said Jing Wang, executive vice president, Qualcomm Asia Pacific, Middle East and Africa. "It not only provides faster speeds, but also creates a better experience for the growing number of people using mobile devices to upload and share data-intensive content, such as photographs and videos. We are pleased to work with ZTE in their efforts to bring ULIC-enhanced base stations to market."http://www.qualcomm.com/http://www.zte.com.cn
