26 February 2013, Shenzhen, China – ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly-listed global provider of telecommunications equipment, network solutions and mobile devices, unveiled its new UMTS Radio Performance Solution at the Mobile World Congress in Barcelona, delivering a 40% improvement in spectrum efficiency to help operators enhance network performance.


ZTE’s UMTS Radio Performance Solution is comprised of four sub-solutions: En-Performance Solution, Capacity SON Solution, MUD(Multi User Detection) Solution and CRAN RRU Solution.


The En-Performance solution offers capabilities for signaling storm suppression, CP/UP resource sharing, bearer pre-configuration, and concurrent handover function, improving RNC performance by 30% to 100%, and enhancing the control plane processing performance of base stations by 60%. The En-Performance solution has been successfully deployed by carriers including China Unicom and Hong Kong CSL.


The Capacity SON Solution utilizes ZTE’s patented power control technology in the uplink, increasing uplink capacity by 35% to 50%, independent of the end-user terminal. For the downlink, the power optimization feature for common control channels will increase the downlink capacity by 10%. In addition, the use of load-based radio parameter self-optimization technology will enhance the user experience.


The MUD Solution, based on IC (Interference Cancelation) technology, significantly increases the system capacity by reducing the interference between users. Result from laboratory testing shows that this technology is capable of delivering a 30% to 60% gain. ZTE’s MUD Solution has been successfully deployed for commercial use in multiple countries, generating performance gains of more than 10% at the entire network level in each deployment. Combined with the upcoming 768CE baseband board, the MUD solution will enhance network performance further.


The CRAN RRU solution is an upgrade of existing Multi-RRU technology, improving network coverage in complex scenerios such as indoor, and street corners in urban areas. The transmission power of the RRU is increased from the previous 80W to the current 120W. In addition, together with the Multi-Antenna Joint Detection and Scheduling, which improves the power and code resources utilization in multi-RRU scenarios, the downlink capacity gain is increased by 50%. Consequently, the site performance with multi-RRU networking is greatly strengthened.


As a leading end-to-end wireless solution provider, ZTE’s technology is deployed in over 140 GSM/UMTS networks globally. In Hong Kong, ZTE is the sole vendor for CSL’s multi-mode network, providing the best 3G mobile broadband services in one of the world’s busiest cities. In Austria, the H3G network was ranked top for two years consecutively in network quality evaluation in German-speaking areas. The 3G network deployed by ZTE for France Telecom in Kenya is providing prime-quality services. The release of ZTE’s innovative UMTS Radio Performance Solution will enable operators improve their network quality and gain a competitive edge in the market.
