标题: 有关telecom和vodafone的选择问题 [打印本页]

作者: 小猫鱼 时间: 2010-11-29 18:56:55 标题: 有关telecom和vodafone的选择问题

最近突然对telecom大发好感，遂对之3G网络做了一点点小小的了解，但是发现了解的越多，明白的久越少，很是苦恼，所以在这里发帖，希望能得到达人相助，得到给力的答案
据我所知，目前世界主流的3G网络分为3种：WCDMA，CDMA2000 1xEV-DO，TD－SCDMA。在有些场合当中，EDGE和WiMAX也会被划分为准3G网络。
WCDMA：包括中国联通在内的很多亚太地区，及欧洲大部分地区都使用的是这种网络。是目前应用最广泛，相对技术较成熟的3G网络；
CDMA2000 1xEV-DO：从CDMA1x发展而来，优势是可以直接在现有线路上进行优化，运行；
TD-SCDMA：中国自己搞出来的3G网络，据说优点很多，但是缺点致命：在网络速率和稳定性上，远远比不上其他。

TD和CDMA2000就不说了，和今天的主题无关。来说说WCDMA：
众所周知，新西兰的3G网络无论是 V 还是 T 都是用的WCDMA制式。
Vodafone的3G网络使用的是WCDMA（UMTS）制式，频率2100MHz，所以外来机都能被接受：国行，港行之流。我估计这也是大多数留学生选择 V 的原因。
Telecom的网络却有点奇怪，WCDMA（UMTS）2100MHz只能在akl，chch之类少数几个大城市使用，全国范围内的频率在850MHz上。

我的问题来了，这几天我在往上遍寻相关资料，850MHz的机器几乎没有，最后好不容易找到AT&T也是用的850MHz，但是机器的选择上，说实话我个人认为还不及新西兰的 T。

我想问问，是不是如果我想加入Telecom的话，只能从它那买机器？
我在往上找遍了850MHz的手机都找不到。除了iPhone，我再也找不到其他途径上，支持850MHz的机器了。

补充：想加入Telecom的原因是，我已经受够了iPhone那令人汗颜的信号接收能力了，更对Vodafone那令人抓狂的信号覆盖率感到忍无可忍。所以决定跳出。

如果您看不惯我写的这些话，请您绕道出去，我不是无聊到来赚取回帖的；
如果我在这里写的有什么错误，欢迎善意的更正和讨论；
如果您能给我提供有价值的信息，我会对您真诚的说声谢谢，虽然不值钱。

谢谢楼上的兄弟的帮忙。
我大体看了看，基本上都是GSM 850的信号，而且北美很多CDMA，但不是WCDMA。
我知道的只有ATT是WCDMA 850MHz的。

本来，大部分3G手机都会向下兼容GSM信号，但是我很恼火的是，Telecom XT Network没有GSM网络。。。只有3G。。。
不给力啊！

Telecom一直走的是CDMA啊所以3G走的也是WCDMA

作者: weapon-lee 时间: 2010-11-30 00:51:24

其實你要是很在意數據傳輸，且經常使用的話，那就沒辦法了。
iphone4信號是不好，但如果你關了3G的話，信號還是不錯的。
需要用封包數據的時候再開啟3G。這是個不錯的解決方法，就是有點麻煩。。

为什么不考虑2d

作者: onlyme618 时间: 2010-12-1 09:06:44

如果你路过荒无人烟的地方，你的vodafone没有信号的时候，连出事都call不了aa来救的时候，你就会想telecome是多好啊（个人经历，如有雷同，纯属巧合）。但是，用telecome就没有朋友啊（绝大数华人在这是用vodafone的）。有点像QQ，360事件一样。。。。。。。

作者: 小猫鱼 时间: 2010-12-1 21:12:07

2d的信号和vodafone一样烂，完全没有理由从021跳到022啊。。。
楼上的倒是说出了我内心真正的想法，我想换027就是冲他的信号好，洋人朋友都用的027。但是笔记中国人朋友还是用的021啊。。。难以割舍啊
难道挂双枪？太土鳖了吧。。。

不同城市他们的市场占有率差别很大的
