5G will finally get its U.S. closeup with the expected debut of Apple<\/a> Inc's next iPhone on Tuesday. But the blazing speeds promised will not materialize for most people.
The device, dubbed the iPhone 12<\/a> by analysts, can tap into 5G, or fifth generation wireless technology, that theoretically operates as much as 10 to 20 times faster than current 4G wireless networks.
Using the next iPhone or any 5G enabled device on today's network, however, will be \"like having a Ferrari ... but using it in your local village and you can't drive to up to 200 miles per hour, simply because the roads cannot maintain those speeds,\" explained Boris Metodiev, associate director of research firm Strategy Analytics.
Apple, which is expected to unveil the new phone at a virtual event on Tuesday, will need to walk a tightrope between enticing consumers to upgrade their phones while not over-promising what 5G can do today.
Current 5G U.S. networks mostly use low-band wireless spectrum, or airspace, that is slower than high-band spectrum, but more reliable over longer distances. It will likely take years before the massive speed boost phone carriers promise will make augmented reality and real-time cloud gaming seamless.
Several U.S. telecom operators have deployed networks based on lower spectrum bands, with slightly higher speeds than 4G. A noticeably faster variant of \"mid-band\" 5G is also being rolled out, but it is unlikely to reach three-quarters of Americans until 2025, estimated longtime Apple analyst Gene Munster of venture capitalist firm Loup Ventures.
The fastest speeds touted by carriers are a type of 5G called millimeter Wave, or mmWave, that work over shorter distances. Verizon Communications Inc has the largest current mmWave network, available only in limited areas.
Although Verizon 5G users could connect almost 10 times faster than on Sprint and T-Mobile, actual average speeds were far lower, according to research firm OpenSignal's mobile signal experience report in June.
On average, AT&T Inc and Verizon customers with 5G phones saw only a small bump up from 4G speeds, according to the same study.
In South Korea and in China, faster 5G networks are more pervasive. But Apple will be competing against local brands including Samsung<\/a> in South Korea, which is already on its second line of 5G phones, and China's Huawei Technologies Co Ltd, whose sales have surged after the telecom giant was banned in the United States.
The other big letdown is that applications using higher speeds to deliver something new have yet to be created. It is a chicken and egg problem at this part of the tech cycle, executives said, noting that interest in 4G was fueled by Facebook<\/a> Inc's mobile apps and Alphabet Inc's YouTube.
\"The applications we will be dazzled by, that will really take advantage of the network, will only be developed once the network and devices<\/a> are available,\" said Morgan Kurk, chief technology officer of CommScope, a telecom equipment maker.
U.S. consumers most motivated to buy a 5G phone<\/a> would be those who need a new smartphone right now and are looking to protect their investments.
\"If you're buying a phone that you're going to have for three years, you're going to want to make sure that it's going to support the latest networks,\" said Geoff Blaber, vice president of research at CCS Insight.
Just know what to expect, Blaber added. \"There's going to be relatively little that you can do on a 5G iPhone you can't do on a 4G iPhone today.\"

分析:新的苹果提供5 g的iPhone 12的速度美国网络无法交货
APPLE-IPHONE-Analysis:新的苹果iPhone5G最终将得到美国的首次亮相的特写镜头预期苹果(aapl . o:行情)iPhone的下一个周二。但是燃烧的速度承诺不会实现对大多数人来说。12“提供5 g速度美国网络不能提供
读到
5克最终将得到美国与预期的首次亮相的特写镜头苹果周二公司的下一个iPhone。但是燃烧的速度承诺不会实现对大多数人来说。
设备,被称为iPhone 12分析师可以利用5 g,或者第五代无线技术,理论上是10到20倍的速度比目前的4 g无线网络。
使用下一代iPhone或任何5 g启用设备在今天的网络上,然而,将“像法拉利……但是使用它在你的当地村庄,你不能开车200英里每小时,仅仅因为不能保持这些速度的道路,”鲍里斯Metodiev解释说,研究公司Strategy Analytics的副主任。
苹果预计将推出新的手机周二在一个虚拟的活动,需要吸引消费者之间走钢丝升级手机虽然不是过度承诺今天5 g能做什么。
目前5 g美国网络主要使用低波段无线频谱,或领空,低于高波段频谱,但更可靠的远距离。它可能需要几年前大速度提高电话运营商承诺将增强现实技术和实时云游戏无缝。
一些美国电信运营商部署网络基于谱带较低,速度略高于4 g。快的明显变异的“mid-band”5 g也正在推出,但它不太可能到2025年,四分之三的美国人,估计风险资本公司的长期苹果分析师Gene Munster苏格兰式跳跃项目。
最快的速度被运营商是一种叫做毫米波5克,或mmWave工作在较短的距离。Verizon Communications Inc .最大电流mmWave网络,只能在有限的地区。
尽管Verizon 5 g用户可以连接Sprint和t - mobile近10倍,实际平均速度低得多,据研究公司OpenSignal 6月份的移动信号体验报告。
平均而言,美国电话电报公司和Verizon客户5 g手机只看到一个小肿块从4 g的速度,根据相同的研究。
在韩国和中国,快5 g网络更加普及。但是苹果将与本土品牌竞争包括三星在韩国,它已经在二线5 g手机,和中国的华为技术有限公司的销售飙升后,电信巨头在美国被禁止发行。
另一个巨大的失望是,应用程序使用更高的速度交付新东西还没有被创建。这是一个鸡生蛋和蛋生鸡的问题在这个科技周期的一部分,高管指出,助推了4 g的兴趣脸谱网公司的移动应用程序和字母旗下的YouTube。
“应用程序我们会眼花缭乱,真的会利用网络,一旦网络和只会发达设备可用,”摩根Kurk说,首席技术官CommScope,原电信设备制造商。
美国消费者购买动机5 g手机将那些需要一个新的智能手机现在正在寻求保护他们的投资。
“如果你买手机,你要有三年了,你会想要确保它支持最新的网络,“Geoff Blaber说,副总统在CCS Insight的研究。
就知道会发生什么,Blaber说。“将会有相对较少,你可以做5 g的iPhone 4 g iPhone上你不能做。”
