WSJ: Earlier this year, China said it would adopt CDMA. To date, it's still on the trial base. Why has nationwide adoption of CDMA been delayed, and will it ever become widely used, or is China going to jump to a next generation technology?
WU: As to whether CDMA will be used or not, it's already been in use on a trial basis in four cities in China. Of course, as to whether mobile phones in China employ GSM or CDMA, there is not really a technical jump between the two but rather, an issue of limited frequency sources, which makes it necessary to use another method. So as mobile phones develop in China, we will need to employ CDMA 800 M-hertz frequency band technology. The Chinese government has said, in terms of frequency bands, that we shall promote the development of CDMA and shall combine trade and technology to engage in industry development.
800 M-Hertz CDMA and GSM, as you mentioned, are of the same technological level. The third generation wideband technology just mentioned is more advanced, and the global trend is moving in this direction. The Chinese government announcement at the beginning of this year about adopting CDMA technology was based on an experimental network which showed that CDMA would be feasible for use here in China. It cannot be guaranteed that a large volume will be reached as soon as it is put into use, there is a process of building and development that must take place. |
