昨天的几个跟进点“Antennagate底线“:

关于iPhone 4和3GS之间掉话的Delta

解释这一点的一个理论是,iPhone 4天线比3GS的天线简直差,甚至可能只是因为皮肤与臭名昭着的地点接触。

乔布斯的“宠物理论”是iPhone 3GS所有者比4个拥有者更容易拥有一个案例,有趣的是,这意味着甚至iPhone 3GS在案件中得到更好的接收(我在他们的天线实验室参观过程中问过这个问题;我得到的答案是“我们不知道。”)

不过,到目前为止,至少有十几位DF读者提出了另一个建议引用一封这样的电子邮件:

In Antennagate Bottom Line, you mention the comparison of numbers of dropped calls, but I argue that this is not the right metric. What one needs to know is if the iPhone4 drops a call that would not be dropped by a 3GSIf the additional drops are in areas that the 3GS would have never connected in the first place, then the statistic isn’t telling us what everyone claims it isAll that would mean is that there is a large drop rate in regions that were previously regarded as dead zonesThat’s an improvement, not a regression.

我会出去承认,这种想法是认为iPhone 4的掉话率更高是一件好事,从表面上看,听起来很坚定But is it outlandish? There are widespread reports —没有比Anandtech更好的了- iPhone 4在以前没有iPhone的区域获得可用接收这些可能包括许多额外掉线。

同样值得指出的是,我也收到了很多来自DF读者的电子邮件,他们说他们使用iPhone 4拨打的电话数量超过以前的iPhone,来自同一地点我从读者那里得到了更多这样的电子邮件,声称iPhone 4得到了更好接待,但对一些人来说,情况更糟有一点我觉得可以安全投注:来自iPhone 4的额外掉线不是均匀分布在所有iPhone 4用户中有些人得到了很多,而且大多数人得到的很少。

关于Apple对天线的现场测试

在过去的几周里,我可能至少发了200封电子邮件,提出以下理论:

我们从Gizmodo窃取的iPhone中了解到,在苹果校园外的情况下,原型是伪装的Maybe that’s why Apple missed this flaw in the antenna: they never noticed it on campus because they have a strong AT&T signal, and never noticed it off campus because the iPhones were always inside cases, and cases mitigate the skin-touching-the-spot problem.

这不合理。

首先,苹果校园AT&T覆盖范围的强弱与他们在实验室中进行的测试无关AT&T内部没有信号那些消声室这些房间内没有来自任何外部无线信号源的信号这就是他们的观点商会的工作方式是他们创建自己的小型迷你网络房间他们进行测试,在这些测试中,他们会产生强大的信他们还对持有被测电话的人进行测试。

另一方面,他们在校外实地测试天线,没有任何情况他们使用大约十几个移动测试实验室的机队这样做这些是货车 - 更像是小型公共汽车,可能 - 包含一系列测试和测量设备。

iPhone Gizmodo获得的是Apple的内部术语,即设计验证测试(DVT)部门这些是生产单位以下的一步我的理解是,当DVT装置被认为准备就绪时,工厂开始将它们作为实际生产单元进行搅拌那些DVT现场测试是最后tests, certainly not the only tests在参观苹果实验室期间,领导此次巡展的苹果公司高级天线工程师Ruben Caballero表示,iPhone 4天线设计已经进行了两年的测试。

最后,这是史蒂夫乔布斯在新闻发布会上所说的:

Again you have to build these rooms, because if you don’t shield what you’re testing from all the outside interference, you don’t get accurate testsAnd you can’t put your equipment in the room eitherThe equipment’s all got to be remoted outside the room. Now this is a state of the art antenna test facilityWe have 17 anechoic chambers这些东西并不便宜We have invested over $100 million in antenna testing facilities over the past 5 yearsWe have 18 PhD scientists and engineers on our staff.

所以iPhone天线经历了这一切We tested it. We knew that if you gripped it in a certain way, the bars are going to go down a little bit, just like every smartphoneWe didn’t think it’d be a big problem, because every smartphone has this issue.

老实说,我认为实验室巡演的重点是加强这一点:iPhone 4天线的表现与Apple预期的完全一样。

把它全部放在线上

我昨天假设乔布斯在宣布免费案件赠品时的暴行与苹果公司将失去的利润有关,我估计保守估计为1亿美元(在昨天下午的分析师电话会议上,苹果估计成本为1.75亿美元。)我没有写的是我是否认为这是一个好主意我说是。

这就是事情上周早些时候,这个天线故事正在失去控制莱特曼列出了十大名单消费者报告每天发布更新,每次都会获得大量流量CNN.com had a front page story stating that iPhone 4 owners could “fix” their phones with strips of duct tape.

有可能如果苹果什么也没做,那么这个故事现在就已经消失了,也许是苹果昨天公布的季度业绩淹没了我认为他们认为不值得冒这个机会 - 如果他们什么都不做,火灾可能会变得更糟而不是消失。

我认为他们明智地决定,如果他们要回应这个故事,他们应该回击他们所拥有的一切没有必要一次一个地运出答案So: a live press conference, not just an open letter from Steve Jobs; a new section on Apple’s website specifically explaining Apple’s argument, and revealing their heretofore secret antenna testing facility; and, yes, free cases, for iPhone 4 users who are having signal problems that go away when the phone is encased.

简而言之:他们不会冒任何风险除了他们没有乔布斯在第二个信息中混淆了媒体批评Apple需要做的消息是天线(是的,它有一个弱点,但它是一个值得的权衡,它不会导致产品退货,支持AppleCare的电话,或大量增加的掉话)以及他们对顾客的关注(我们希望他们感到高兴,所以我们放弃了退货的补货费用,我们正在给任何想要一个iPhone 4用户的免费案例)。

乔布斯传递给媒体的额外信息是:他们把这个故事搞砸了,报道“如此夸张,令人难以置信”肯定这就是乔布斯真正相信的,我认为这是事实不过,我不认为Apple会在此次活动中提出这个案例If the Antennagate PR problem was so dangerous that it warranted a significant response from Apple — and I think it did — then it was dangerous enough that it shouldn’t have been mixed with a message that might further antagonize the media — the very media whom Apple was clearly hoping would spread the facts Apple had presented regarding the antenna and its concern for customer satisfactionIt doesn’t matter whether Jobs was right; it distracted from the core message, which was all about dissipating the meme that the iPhone 4 antenna is severely flawed.
