http://www.3gmodem.com.hk/Huawei/K3565.html China moved lets the world know TD-SCDMA; But at May, 2010 Shanghai World Expo, China will move will complete the global biggest TD-LTE experiment network, will provide the communication services for the World Expo. Because the present China moves in the World Expo scene measured data transmission speed, has achieved 70Mbps, approximately for the existing 3G technology 20 multiple, therefore, what may foresee, at the appointed time China will move will enable TD-LTE to become the global communication industry attention once again the focal point. Mentions TD-LTE, chats anything is LTE first. What LTE refers to is the 3.9G global standard, it has two kind of service pattern FDD-LTE and TDD-LTE. LTE is not the 3G substitution technology, but is the 3G most important promotion technology, it can meet the high grade migration broadband business need which the present 3G technology is short. The LTE technology downward peak value speed can achieve downward 100Mbps, on behavior 50Mbps, has the high data rate, the packet transport, the detention to reduce, the macrozonality cover and the downward compatible characteristic. But TD-LTE has not been difficult from the wording to see is the TD-SCDMA promotion version, because it is in keeping with the current wide band mobile communication development tidal current, can also satisfy the competition request which China moves, therefore K3565(vodafone) TD-SCDMA also moves to the TD-LTE smooth transition by China takes future important strategic plan. LTE may satisfy the user without doubt in an experience aspect higher demand, because China moves regarding the LTE forward-looking deployment, also has been placed by the user more expectations. But in the present case, the author believed that the user should abandon technology's fetter temporarily, pities takes at present, the total involvement understands the infinite charm which present 3G unfolds. Because, the technical evolution must follow its law of development, is gradually thorough, in the present case, LTE is impossible to reach one's goal instantly. First, the LTE development needs a stage. Communication's evolution is impossible to get it done in one action, needs to have a process, will involve among this process to the standard formulation, network deployment, industrial chain's consummation and so on links. Moreover, the domestic three big operators aggressively are carrying on the 3G network construction at present, at present 3G already could provide, many and varied services very well, the user uses the 3G service to be able now to propose a higher demand to LTE. Next, public's use custom, the consumption habit need to have the cognition process which proceeds in an orderly way. It is well known, the domestic majority of users also merely are in the concept level at present regarding 3G, 3G must welcome the eruption-like growth, but also needs the operator unceasingly to increase dynamics to carry on 3G to the user the popularization. LTE is one item renews a more formidable technology, but the present user indicated to the 3G cognition foundation also K3565(vodafone) quite weak reality, with develops 3G to be the same, LTE is accepted by the user also needs certain time. Moreover, a more important spot is, is the same with present 2G and the 3G coexisting aspect, LTE and 2G, the present 3G technology as well as President LTE several between the time coexistence, and composes a mixed style the shape, this kind of shape will become the next generation not to have the way which in the future the present network will mainly present, at the appointed time, can construct the cognition process which for the user will proceed in an orderly way, simultaneously can also provide the even more multiplex service for the user, will let the user act according to own situation, according to his need. In summary, 3G is also good, LTE, the technology promotes the core looks at the user's needs the change, only then can understand the 3G charm fully in the user, and produces Gao Wangsu, the high performance demand premise down to discuss that LTE the development will have the practical significance.
Only then in the cognition 3G foundation discussed that LTE is only then meaningful
