Nexus4没有LTE，Google的官方解释

ysihaoy

以下是Google的官方解释，大家英文都不差，不翻译了，自己看吧，太多了。。。转自AndroidPolice

If you haven't heard by now, the Nexus 4 doesn't have LTE. It probably won't ever have it, either, based on what Andy Rubin told The Verge regarding the latest Nexus handset's network situation in an interview.

He talks a lot about "tactics" and "user experience" (read: battery life), but it really boils down to one issue: money. The fact that the unlocked 8GB version of the Nexus 4 is just $300 is absolutely crazy. Looking at the hardware, this is easily a $600 phone. Having used an Optimus G (the platform this phone is based on), I already know this is a truly premium device. The processor is the fastest one in any Android phone on the market, and the display is brilliant.

So, how can Google afford to sell it for $300? Honestly, I don't think they can - I'm pretty sure they'll lose money on each and every one of these. If, by some miracle, they're being sold through at cost of production, they're still going to lose money on things like advertising and R&D. Anyway, why is this relevant to the Nexus 4 lacking LTE?

Like I said, the interview with Andy Rubin comes back to two issues: the user experience, and the network compatibility ("tactics"). The user experience part is explained as being an issue of battery life, but really, Andy Rubin somewhat unintentionally lays bare a big issue with LTE: two radios. This adds to cost of production in two ways.

First, you have to pay the piper (eg, Qualcomm) for an LTE baseband chip, which involves lots of patents and licensing arrangements that probably make it fairly expensive. Second, you have to then make sure that LTE chip doesn't decimate the battery life, or in some other way make the user experience worse (connectivity issues, for example). Making sure that stuff works (on multiple networks) takes time. If you want a Sprint or Verizon version, you need a CDMA radio. Qualcomm does make "all-in-one" radio chips that work on pretty much every network out there, but as I said, these are probably significantly more expensive than the 3G-only models. You'd then need different software versions for each carrier's radio configuration, too. That means more work to support the hardware post-sale.

As for CDMA, then you have to deal with carriers that won't allow you to bring just any device onto their networks. Verizon has to certify and approve any phone on its network - 700MHz block C "open access" provisions be damned, because Verizon's CDMA network basically nullifies those requirements. Sprint is the same. That then means these carriers don't want you selling the hardware strings-free. They want to sell it with a contractual commitment. Then there's the cost of carrier certification, and going through the carrier software update approval regime. And that's if Verizon even wants a Nexus phone after its numerous PR boondoggles with the poor-selling Galaxy Nexus.

So, with CDMA out of the picture, bringing an unlocked, GSM LTE Nexus that's really only fully compatible with AT&T's 77-market LTE network to market probably wouldn't be worth the money, especially when you consider how historically poorly Nexus phones have sold. This is where Rubin's logic about UX and "tactics" does fall apart a bit, though - why not just have an LTE mode toggle switched to "off" by default, so 3G-only network subscribers could use it as a normal GSM device? And that's why I think cost is the larger issue.

Rather than play ball with the carriers (and pay the cost of that game), Google has thrown up its arms and said "forget it - we'll do it our way." Which means they're going back to the model they originally dreamed up with the Nexus One. Which seems kind of silly, in a way. But I like that idea, especially when the hardware costs half of what it did when they tried it the first time. Who knows - this might actually work.

But the fact that even the iPhone 5 now has LTE, whereas the latest and greatest from Google's Nexus line does not, is certainly a bit of a slap in the face for the Android-faithful. Then again - it is $300.

300固然好，可惜无双卡双待。

也不是，不是说note2就是双卡么？
我最近入了p700i， 到手才发现“深度订制”，不爽
要搞一大堆才可以上google service。

我的时间很宝贵，但是现在也要投身于刷rom 行列了。

我不知道国内版本的note2会不会也被深度订制，我现在才知道p700i海外版本和国内版用不同的rom

wp看来要上，至少给老爸弄台，但不会是nokia，不看好他。 ms的东西没有sp1是信不过的。它第一个出就是”

就没考虑过note2，哪玩意不是正常手机。。。也顺手查了下，双卡也就中国才有啊，好像年底才出？

不过这回是LG做的，不是三星的了。

note 2 支持 dual sim吗？ 好像只有note支持吧。 还有那种magic sim不知道如何。

这是一个重来没有考虑过的问题。因为这边看到的手机都不那样嘛。

所以要正告在国内买android 系列的同学。要做好root机或者刷机的打算。

note 2现在能root和刷机吗？

彻底不懂，但是对双卡的note 2开始长草，  就想换个大点的屏幕， note 2, nexus 4, lumia 920 眼睛都花了，咱又缺米之人，否则一样来一个就省心了。

针对你的签名：国产的Android这么烂啊？那不就是被阉割一样吗？说实话喜欢Android机器，有一半的原因是因为其Google的应用和支持。

什么小米，魅族，华为都这样啊？我对中国市场了解真是out了

双卡那么重要吗？

我觉得Nexus 4应该是Android手机中出类拔萃的了，今天在网上真没注意和note2的比较，但是和其他机器的比较是非常出色的。。。

还是推荐Nexus 4，没用过三星的，不清楚它的UI怎么样？不过我更喜欢stock android，另外有朋友说不喜欢三星的屏幕。。。

eric_gao

我平时带公司的手机，随便打电话，数据一个bit都没有， 个人电话tpg $1 pay as you go, 转到公司电话。 另外公司还配一个dongle， 3个G的data，每月一个bit都用不上， 你说我这样的，怎么弄最合适呢?

我最希望有个三卡两待。
我希望公司手机打电话，dongle sim来上网，个人电话纯待机接听。   tpg的pay as you go,  每次成功转接一次，额外收一次钱， 另外到在外面没有网络真的挺可怜的，想过带个wifi modem，但是还是太大，跟拿一个手机也差不多了。

据说是故意的,首先是国内政府不爽GOOGLE, 然后改过的系统都是在什么移动商店, 联想自己的"乐商店"买APP.钱就是进去他们的口袋.

我昨晚解决问题了,就是刷同一个机型的海外版(就是在海外发卖的版本)ROM
之后就清爽了,GOOGLE 全套SERVICES回来了,然后没有乱七八糟的预设程序.

果然就如一些刷机论坛上的留言 --"专坑自己人"

我没有研究过NOTE2, 不过刷机工具应该都是那套. 就是现在没有也会很快有.
NEXUS 4看着很高性价比,不过就是无双卡我就不买. 还有就是韩国货我是无好感的.


还是不看好NOKIA的920, 第一款新一代WP, 硬件厂家要摸索,软件厂家要慢慢改进.何必去当人家的小白鼠?等到其它厂家跟上来了,MS发几个补丁也不迟.

WIFI MODERM很小啊. 你看过哪款? 现在满大街都是可以轻易UNLOCKED的华为POCKET WIFI2.
你们公司的套餐真是奇怪.
如果你的TPG不接SMS的话,只要设置好了电话转接. 那么可以不需要把它放在一个手机里面了. 所有来电一样转的.可惜现在没有SMS转接服务.
那么你只需要一个双卡双待, 把你公司的3G DONGLE里面的SIM拿出来,作为主卡. 然后把公司TELSTRA SIM作为副卡就好了.(对于绝大部分双卡双待手机,只支持主卡用3G上网络,副卡都是GSM 2G)

eric_gao

然后在配一个socblue a180+ 这个东西支持call& SMS 转接到 IOS 或 android . 这样就四卡了。对我来说，三卡才够。

A180 一卡，a180+ 双卡: 一卡2g  gsm 一卡 edge 2.75g, 也就一拨号modem速度。
