ZTE: CDMA can not be replaced by LTE

ZTE Cdma&lte Product line chief technology Officer Jiang Tao C114 News June 20 (in Arts Wan) three days of the 2011-year wing 3G Internet mobile Phone Fair on June 17 in Guangzhou Pazhou Convention and Exhibition Center opened the curtain, the fair will be held during the "2011 CDMA World Forum", "Global CDMA operation and Development forum" and "China Telecom CDMA industry chain Summit Forum".　　C114 to participate in the "2011 CDMA World Forum" ZTE Cdma&lte product line chief technology Officer Jiang Tao interviewed. The topic naturally begins with ZTE's newly launched global first Cdma/lte dual-mode 4T4R distributed base Station system. The system's unique MIMO (ListBox input ListBox output, Multi-Input and multi-output) technology, can be flexibly decomposed into two 2x2 or 4x4 MIMO, with large bandwidth, effectively cover the scattered spectrum of operators resources; greatly enhance the coverage and capacity of the cell,　　At the same time, it also improves the spectrum utilization of the network, helps the operators to accelerate the network deployment speed and reduce the cost of network construction greatly. CDMA will not be replaced by LTE at the time of 4t4r release, ZTE Cdma&lte products general Manager Li Yu said: "ZTE in the CDMA to LTE evolution to maintain the industry leader, ZTE in Dallas, United States has built a C-L dual-mode open laboratory." The Cdma-lte dual-model test network has been conducted in several markets, including the United States, and ZTE is actively helping CDMA operators evolve to LTE using State-of-the-art uni-_ran programs. "In the process of evolution from CDMA to LTE, will cdma-lte dual mode be a transitional state, or is it possible to coexistence?" Despite many of the industry's view that the technology of MIMO and OFDM Technologies will eventually replace the current CDMA-core 3G technology, but Jiang Tao clearly said: "CDMA will not be replaced by LTE." "ZTE's understanding of CDMA is a long-term in-depth study." CDMA can not be replaced by LTE, from the current network and the future evolution of the view, are superimposed, not replace. "A new LTE operator is bound to provide voice services through 3G or 2G," Jiang Tao said. "The carrier's deployment to the LTE network is due to the high-speed data services it offers." If LTE is provided only as a data service network, Jiang Tao believes, this is only for small operators. "Because a separate data network for users is not sticky, the size of the operators will choose 2G or 3G network with the LTE network to provide users with voice + data services, so ZTE believes that CDMA can not be replaced by LTE." "Force-push intelligent pipeline solution" in China Telecom held the sky Wing 3G internet phoneThe trade fair, the mobile phone is the protagonist, ZTE as always committed to the field of CDMA terminals, in the trade fair with China Telecom Tianyi Terminal Company, in the Mail Protec, Putian too force, audio communication and cool people communication five channels signed the terminal purchase agreement. ZTE will launch more smartphones, and the relationship between smartphones and the internet is getting closer, said Li Jichao, general manager of Zhongxing's CDMA mobile phone product line. In this respect, Jiang Tao points out, the change that the smartphone brings to the whole industry is revolutionary.　　Smart phones need seamless coverage of the network, the need for faster speed, the need for timely service, all these operators put forward a small challenge. "So ZTE will provide operators with good service as another leg of development." ZTE's Intelligent Pipeline solution (ZSP) will make more efficient use of resources, efficiently maintain the network, and improve user experience. It can help operators to conduct business and data analysis, make the management more visual, controllable, improve the utilization rate and better service users.　　"Jiang Tao said. The introduction of ZTE and Qualcomm's air mobile broadband system in the United States is a manifestation of intelligent plumbing services. According to Jiang Tao, the service is now available on more than 1000 aircraft in North America.　　China Telecom also has a passion for the service, and ZTE has become a partner in the promotion of air broadband services, but it will take some time for the service to be opened. "In addition to services, ZTE this year in the CDMA field has two points, one is CDMA 1X Advanced, recently, ZTE combined Qualcomm completed the industry's first CDMA2000 1x Advanced IoT Test, the year will be commercial; another focus is CDMA EV Advanced will also be tested this year. "Jiang Tao said.
