大陆可能迟D 出3G 系呢种格式喔....甘E+噶果D 3G机..用5用到呢个网络架?如果唔得..咪要局住买大陆野.....

TD-SCDMA 未必會用，好似話穩定性未能完全通過國家標準。

不過大陸整呢個system 出黎...係為左慳$ and 賺$...
佢咁耐都唔出 3G...好有機會同個td-cdma 有關...

你睇多D人民網啦...成日會講

你望天打卦求神問卜, 望中國網通/電信拎到3G牌啦
因為呢兩間講到明一定會用WCDMA
中國移動就難講, 因為國家分配左155MHz(個單位冇錯)既頻寬俾TD-SCDMA
用WCDMA同CDMA2000既新頻譜先得60MHz
聯通就用硬CDMA2000, 因為佢本身已經有成一大段800MHz範圍既頻譜搭夠
而且可以平滑過渡, 成本都係低
以政府對聯通既支持度, 聯通要哂成個標準800MHz應該都冇問題
所以佢就唔駛擔心唔夠頻譜用

如果中國移動用TD-SCDMA, 佢既建設成本會低唔少, 特別係城區
因為基站數目可以少好多
再加上用TD-SCDMA既話, 政府會大量提供優惠, 甚至貼錢

另一個方向就係TD-SCDMA+WCDMA混合組網(城區以TD-SCDMA為主, WCDMA做輔助, 郊區就WCDMA only)
情況同依家既FOMA+UMTS類似
因為NTT個FOMA本來就唔可以用國外/Vodafone既3G機, 因為FOMA唔兼容UMTS, 但依家好似解決左個問題, UMTS機都可以用FOMA了.

我相信如果TD-SCDMA同WCDMA之間交接得好, 移動應該好大機會用

你話唔係都冇人信啦

但另一個原因係因為中國始終係發展中國家, 3G呢D高消費+高投資額既野唔係時候上馬, 如果唔係蝕左既話就麻煩, 始終電信商間間都係國家資產....一蝕錢除左股東要貼, 國家都要貼

應該係
移動用wcdma
聯通用cdma 2000
國網通/電信TD-SCDMA

中國咁多人口，一定有市場，日本咁細都可以support PDC、PHS、CDMA、WCDMA 咁多網絡系統

大陸玩下手會出WCDMA/TD-SCDMA 雙模機啊

(就快出WCDMA/CDMA2000雙模機)

網通高層一早講到明用WCDMA

反正佢對頻寬需求不大

WCDMA/CDMA2000我可以寫包單一定唔會普及
因為兩個standard完全唔同, 被淘汰就必然, 所以只會係過渡/試作品
反而TD-SCDMA+WCDMA就有機, 因為硬件上同WCDMA有9成接近, 要解決只係軟件問題

中國人口係多, 但可以有高生活質素, 有閒錢玩3G o個批
只係得4000萬, 比一個東京都既人口只係多1000萬, 而且分散好多

I think the mainland government is still waiting for the result of the testing on TD-SCDMA.
First, China government needs a system developed by them to use on future. To develope a 3G system, not just provide a 3G mobile or station. It also can train and maintain a lot of human resource, keep to developing on technoloy in future.
Second, if China can have a system developed by them, they can save a lot of licence fee which is need to pay to Korea, EU, japan & usa.
Third, For Nationial Security, there have too much security problem to use the system of outside. You have to understand the CDMA technology was developed for the milility of usa; it have too much backdoor just like microsoft windows & GPS. There will have more conflict in future; It's not safe to hold your Big-John on the hand of your enemy, right ?
Finally, It can be use on bargain even TD-SCDMA cannot become a standard. Same as the China WIFI standard, because usa fear China make/own a standard will effect their benefits, they start a political meeting with China. To be compelled China to give up their standard, usa pay a lot on that. So it may be a trick of China again.
But i am still waiting / Support China to have their own standard.
If everything in on schedule, 3G service will start at least 2008, no more no less.

實際上...其實 wcdma 係郊區既 服務都可能可以慳返...or 只需要少量容量..
用得 3G 既都係高消費群...集中係大城市...
and 中國咁大...要 大量建網...成本係個好大既問題！
