Tianqi Technology took the lead in implementing the industry's first TD-SCDMA dual-band switching under ZTE
At the 2008 China International Information and Communication Exhibition, Tianqi Technology will showcase the industry's first commercial dual-mode terminal solution T3G7210 that supports TD-SCDMA dual-band (ie 1880-1920MHz and 2010-2025MHz). The solution fully supports TD-SCDMA's A and B frequency bands, and cooperates with ZTE's network equipment to take the lead in successfully switching voice and data services between dual frequency bands.
It is reported that ITU has specified a total of 55M bandwidth for TDD in the 1880-1920MHz band and the 2010-2025MHz band. The relevant leaders of the Radio Administration Bureau of the Ministry of Industry and Information Technology have clearly pointed out that 1880-1920MHz is the core frequency of the domestic 3G standard TD-SCDMA that has been planned. The 1900-1920MHz band currently used for PHS will be gradually transferred to China Mobile for TD-SCDMA. SCDMA. In China ’s current TDD plan, 2010MHz ～ 2025MHz is also mentioned as the core frequency band, which is mainly used to build a nationwide continuous coverage network to provide voice services and low-speed data services; while 1880MHz ～ 1920MHz is more suitable for high-speed data services, such as TD- HSDPA / HSUPA / HSPA + and other services, indoor coverage in special scenes and network optimization to meet users' demand for high-speed services.
The core chip TD60291 designed by Tianqi Technology for the T3G7210 solution uses an advanced embedded vector processor (EVP), which can well support TD-HSDPA / EDGE dual-mode automatic switching, and supports 2.8Mbps TD-HSDPA and TD-MBMS can better meet the needs of operators and users, and help terminal manufacturers produce commercial terminals with a wide range of 3G multimedia applications. Not long ago, Tianqi customers' TD-HSDPA commercial terminals based on this solution had obtained the network access certificate from the Ministry of Industry and Information Technology.
The heads of Tianqi Technology and ZTE both stated that the successful implementation of TD-SCDMA dual-band switching through the joint efforts of the R & D personnel of both parties has fully proved the feasibility of TD-SCDMA dual-band networking and made TD-SCDMA more extensive. Application and commercialization prospects.
