The personage in the know reveals, China Telecom is fermenting its staging once again of 3G network correctly, adopt CDMA 3G technology of the latest edition, will make 3G speed 3 times faster than now, the theory speed reaches and descents 9.3Mbps.
Begin to test staging edition 3G technology in July
What China Telecom 3G network adopted is EV-DO Rev.A edition technology (hereafter referred to as A edition) at present ,Behavioral 3.1Mbps under the theory speed, but apparatus traders have already developed EV-DO Rev.B edition technology (hereafter referred to as B edition) ,Behavioral 9.3Mbps under the theory speed. It is reported, China Telecom is assessing and adopting EV-DO Rev.B edition technology, will start to test in July.
This move is mainly caused by speed competition between the operators. CHINAUNICOM has already announced, the highest speed 14.4 Mbps in order to descent of technology that its WCDMA network adopts, WCDMA is terminal at present the speed is 7.2 Mbps, so stage introduces and descents the speed of the highest 7.2 Mbps at present, this causes China Telecom to attempt to exceed instead technically too.
The relevant personage admits too frankly, CDMA 3G technology whether China Telecom really introduces the staging edition should depend on two conditions: First, there is market demand, one is system equipment and terminal maturing status.
It is reported, the apparatus could introduce CDMA 3G apparatus of the staging edition in the fourth quarter of this year in Shang, however, the terminal station should be late. In the industry to estimate B edition chip of high pass will come out in the fourth quarter of this year, than system manufacturer late three months. CDMA such newest 3G terminal station can come out until next midyear.
May adopt in the whole world first
There is no operator to use in the whole world so far in CDMA 3G technology with latest this, China Telecom seems to become first to adopt this newest technical operator unless you give your whole attention to it, technology will exert an important influence to network to global CDMA. So, what a choice highly attracts attention for the industry on the issue in this of China Telecom. At present, China Telecom has not determined finally yet either, Japan KDDI is considering this too, obviously the attitude of China Telecom will exert an important influence on Japan KDDI too.
One of these very important decision this in factor, when can come LTE really, whether B edition technology will become very transient transitional technology.
As to this, the insider thinks, " release 3G license plate of China to wait for 78 years, no one knows when to release LTE license plate. In addition, LTE also needs to solve a lot of technical matters, can not get on horse soon. After LTE large-scale construction wants until 2012 years, so, before this, China Telecom needs to have B edition " .
