不過,一个新的技術,一定是成本比較高的。 一个新技術,從大學的實驗室搬到真實環境應用,一定遇到很多没想到的困難,要在經驗累積後一一解決,而累積經驗雖要時間,就是金錢,最重要是會失去市場。從蕊片,手机,到發射基站,我可以想像TD的建設都會遇到没有前人解決過的問題。 所以聯通和電信用外國巳運行多年的系統來搞3G,是有advantage. If problems happen, it is very likely that there is a solution out there.
There is no doubt that China Mobile is losing 3G market to China Unicom and China Telecom. It now depends on whether China Mobile can leverage its strong cash flow to quickly improve its TD technology to be on-par with WCDMA and CDMA2000. If it does not happen on time, it is going to be a problem. Market does not wait … …
However, >4% dividend is a pretty safe bet for this year. I would keep a very close eye on the 3G market.
最近經濟學人有篇文章, 頗合你的理念.

MATHEW 所轉發的新聞我也有看過,但想了一下後,也得不到多大的結論,文中所指3G的投入,是單指基站的投入,還是總3G的投資(包括蕊片的投入,手机的補貼,TD技術的開發等?)。 那則新文太慨是引導讀者聯想TD的基站成本要比聯通和電信的貴。
不過要認真的比,就要找到一个TD基站能cover是多少地方?它的負戴是多少(e.g. 同一時間能有多少話音和數據的流量)。再和聯通電信比較才有意思。 但我也没有這方面的數據。所以在那文章中也找不到結論。

我看過一些文章,中移在建TD基站的初期,要求很粗的通信銅錢,按裝到樓頂有很大的困難,業主對粗的銅錢很反感,最後要用光纖來解決,這就是新技術learning curve的一例。
更不用說 “economy of scale",聯通的WCDMA手机差不多全世界也在賣,WCDMA的手机當然會便宜。
所以我多次說過中移想在TD上同時再來一個新的OPhone軟件系統,要2個新東西一起推到市場,風險太高。。。。成本就更不用說。
