At present, in the domestic 3G market, China Mobile's TD-SCDMA system is restricted by technical maturity and terminal supply, and the development of 3G users has been greatly affected. In the domestic 3G market competition, China Unicom has gained a lot of high-end 3G users by virtue of its mature WCDMA industry chain and strong "star" terminals such as the iPhone; China Telecom has also made efforts in 3G terminal subsidies and channel cooperation recently. The development of Tianyi 3G is full of stamina. Since it does not have much advantage in the competition of 3G, launching 4G products first and occupying a part of the market first to win the first-mover advantage may be one of the reasons why China Mobile launched the TD-LTE network card this time.
From a technical point of view, TD-LTE is still far from the requirements of 4G indicators proposed by the International Telecommunication Union, but the OFDM and MIMO used by them are the key technologies of 4G in the future, so they are often called 3.9G or "quasi 4G ". With the evolution of technology, TD-LTE will also officially "upgrade" to 4G. In October last year, the International Telecommunication Union determined LTE-Advanced and 802.16m as the new generation of mobile communication (4G) international standards, including China's new generation of mobile communication technology TD-LTE-Advanced.
Although TD-LTE is technologically advanced, it still needs to be tested by the market. Regarding the acceptance of the TD-LTE Internet card, a domestic portal conducted a survey. The results showed that half of netizens were interested in 4G Internet cards, while the other half said they would not purchase it. This may have something to do with the usage habits of domestic users for wireless data services. When users' demands for data communications increase, more people may be interested in 4G.
At present, China Mobile has begun to exert efforts in the construction of 4G networks. On Monday, China Mobile stated that it will build a TD-LTE technology test network with more than 1,000 base stations in 7 cities including Shanghai, Hangzhou, Nanjing, Guangzhou, Shenzhen, Xiamen and Beijing, and will launch TD-LTE in the second half of 2011 The network card is used for user experience. The company has also signed TD-LTE cooperation agreements with a number of international operators and promoted the construction of a global TD-LTE trial network. In the long run, vigorously promoting the construction of TD-LTE networks will help improve the infrastructure of 4G networks and allow users to enjoy 4G as soon as possible. But in the short term, based on considerations of return on investment and existing user structure, China Mobile still needs to balance the four networks of GSM, TD-SCDMA, TD-LTE and WLAN. The launch of the TD-LTE Internet card is regarded as the first step taken by China Mobile on the road to 4G. I believe that through a period of user experience, users can test the "heat" of 4G, thus investing in and promoting the 4G network Have a more accurate grasp of speed and other aspects.
