Recently, China Mobile has accelerated the process of TD-LTE commercial, which includes  to promote TD-LTE 7 trial cities and building of more than 1,000 base stations with TD-LTE test equipment tender, and also announced the launch of TD-LTE in the second half on the wireless modem. In this regard, given the industry's most bullish expectations, more companies and executives predict TD-LTE 4G is expected to drive more than 500 billion yuan of investment.

I believe that, in accordance with the plans of China Mobile, but it is not in the building during commercial-scale pilot demonstration project. Because of the pilot, the 1000 seem excessive amount of base station construction, and there is no need at the same time in 7 cities. In addition, the industry "500 billion investment in the feast," the expected represent an investment impulse. At present, China's TD 3G business has not effectively promote, network performance is far from able to play the urgent need to improve network coverage and improve the user experience. 3G investment has not yet recovered in the premise, how can it talk about 4G 5000 billion investment? The author suggested that in promoting TD-LTE and 4G, China Mobile and other industry body should focus on avoiding a repeat of "investment-led development, without considering the benefits" of development.

In fact, the telecommunications users, the simple meaning of the wireless network speed is not large, only when the 3G network capacity and application rate can not meet the needs of the user, the user will be on TD-LTE and 4G generate demand. Today by contrast, 3G network capacity has not been well used, the user does not TD-LTE for more strong demand.

In addition, the development of mobile Internet applications will also depend on low-cost high-performance smart phones and other terminals Pad popularity. The TD-LTE relevant terminal is not yet mature, the size of trials, China Mobile is only involved on the card terminal. On the card is mainly used in notebook computers, is a complement fixed broadband network, taking into account in the office and home users will use a fixed network or a Wi-Fi networks, and business hotels and other public places have also been deployed at present most of the Wi-Fi network, users demand for the use of the card downward trend over previous years. Coupled with the scale of the TD-LTE test deployment of hundreds of base stations in each city, poor coverage, it is conceivable test on the card provided by the network service will complement existing 3G networks, it is difficult to play a good business model effect, not to mention the influence of scale users.

I believe that, TD-LTE pilot should have more specific goals, with particular attention to co-exist in the test city 2G/3G/TD-LTE TD-LTE scene to determine the position and related effect. In summary, TD-LTE-scale test should solve technical problems, coordinate and promote the development of the main chain, and for demonstration projects, China Mobile, 3G should not slack off do what the premise of the commercial development.
