Qualcomm Incorporated and ZTE Corporation declared their collaboration to significantly boost the capacity and performance of UMTS systems with the integration of Qualcomm's Uplink Interference Cancellation technology into ZTE's next-generation UMTS base station products. This technology enables operators to increase their UMTS data throughput by up to 60 percent and deliver a user experience that is comparable to LTE in a similar channel bandwidth. Besides, with the technology, UMTS operators can increase voice capacity by up to 45 percent.
ULIC technology can deliver improved system capacity by eliminating interference from multiple uplink data streams and bring the performance of CDMA-based modems close to their theoretical limits. Jing Wang, executive vice president, Qualcomm Asia Pacific, Middle East and Africa, said interference cancellation helps to redefine the performance characteristics of UMTS by improving system capacity and delivering data throughput that is on par with LTE networks. In addition, it 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. The design is scalable and supports cancellation for a large number of simultaneous users and transmissions on the uplink.
Zhang Jianguo, general manager of ZTE's UMTS products, said: “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.”
