China mobile use 4G to accelerated layout TD LTE
|
China mobile recent series of actions show that TD - speed might come to LTE faster than expected.
LTE, accurately, but speak not 4G, belong to 3G 390 G theory of evolution, transmission speeds higher than the current 3G standard, also be outside called quasi "4G".
However, whether "4G" and not the focus, the keen than China mobile, China unicom and China telecom attitude is not positive, but direct mount TD - LTE concerned, for China mobile apparently meaning more significant.

"Currently TD - LTE trial network construction has launched." Guangdong mobile insiders told times reporter, guangdong's relevant weekly newspaper, but the network construction has begun to previous reports September construction to be completed work, this personage says, there has been no specific timetable.
But the message says, TD - LTE will be incorporated into the "guangdong mobile wireless city" strategy, i. e. "TD of wireless local-area network (WLAN)" - LTE + covered scheme. This is not to be unfounded, according to time weekly reporter understanding in guangzhou, after moving and guangzhou informatization office of the cooperation agreement signed, China mobile and puts forward "TD - SCMDA + WLAN" construction scheme of wireless city of guangzhou.
3G competition is no longer competitive
However, this does not speed up TD - mobile hope the main cause of LTE, widely thought SCMDA systems, TD - not mature is the major reason.
China mobile with apple star product first intervention in the iPhone, many negotiations negotiations and no success into iPhone WangJianZhou had already, in fact, to journalists, and apple negotiations have no other obstacles, and the reason is the key negotiations in late type.
One industry experts have told The Times reporter, apple is difficult to separate weekly development of td-scdma mode, after all, the iPhone in the global scope, only China mobile large-scale use such formats, individual development will increase their development costs.
But in March, and WangJianZhou to journalists, jobs has expressed a desire to develop a paragraph of the iPhone LTE. |
