With the 2010 Shanghai World Expo approaching, the first TD-LTE trial network in China was officially opened recently in the Expo Center. The field measured data transfer rate reached 70Mbps, which increased by 20 times at least compared with the existing 3G/HSPA system in China.
TD-LTE is the mobile communication standard for LTE TDD mode, and the unique technical standard whose core intellectual property is owned by China, as well as an future evolution of the 3G standard TD-SCDMA. The capacity of TD-LTE systems in theory can reach 100Mbps and 50Mbps on the downlink and uplink respectively. It has the characteristics including the high-bandwidth and the high spectral efficiency, which is suitable for carrying high-speed data services particularly. Covering multiple venues, the opened TD-LTE trail networks will serve the World Expo site during the opening period and bring the new experience for the users via the TD-LTE data cards.
Additionally, the joint test of LSTI TD-LTE FCT (Friendly Customer Test) M12a stage by China Mobile and Huawei has been completely recently. The test results are satisfied, including the throughput, latency, mobility, coverage, multi-user scheduling and user experience, etc. In the next stage, the parties will cooperate with each other deeply in the TD-LTE end-to-end solutions, the large-scale networking, the network performance and the IOT, to promote the commercialization process of TD-LTE together.
Meanwhile, the global development of LTE is also fast. According to the data from GSA, as of early December in 2009, 51 operators in 24 countries had announced the commercial strategy for LTE, while some of the others had launched the LTE test and validation, which means the parties on the LTE industrial chain are preparing for the commercial use. Actually, from the current LTE development process, the Nordic operator leads the world. On December 2009, TeliaSonera as the largest operator in Nordic countries announced that its LTE networks in Oslo and Stockholm had been opened firstly on the worlds, which were deployed by Huawei and Ericcson, with the downlink data transfer rate as 43Mbps and 96Mbps respectively. The difference of the data rate was caused by the bandwidth from the operators but the technical problems. In addition, TeliaSonera also announced to sign the contracts with Huawei, Ericcson and Nokia-Siemens to continue the large-scale deployment of the LTE networks in Norway and Sweden.
