CNN News: 5G网络

Forty years after 1G or first generation wireless technology arrived, 5G is finally upon us, or is it? There’s a lot of excitement about how faster wireless speeds could change our lives but even though 5G technology is now available in a few American cities, one analyst says don’t hold your breath. It could take as long as eight years before its available in as many places as 4G right now is. CNN’s Samantha Murphy Kelly tried to take 5G for a spin.

在1G或第一代无线技术问世四十年后，5G终于到来了，对吧?人们对更快的无线网络速度将如何改变我们的生活充满了兴奋，尽管5G技术已经在美国的一些城市可用，但一位分析人士表示，但仍不实用。它可能需要长达8年的时间才能在目前4G网络应用许多地方使用。CNN的萨曼莎·墨菲·凯利试图尝试5G网络。

SAMANTHA MURPHY KELLY, CNN BUSINESS EDITOR: So this is an actual 5G cell site location here in the East village. You can see that the 5G site is sort of a small rectangle on top of a longer vertical rectangle and there are other 4G sites around it. The 5G T-Mobile site allows sort of this high band millimeter wave to kind of cast a spectrum down and you’re able to access these higher speeds if you’re in the vicinity around it.

CNN商业编辑萨曼莎•墨菲•凯利: 这是纽约东村5G手机的实际位置。你可以看到，5G网站是一个小矩形在一个较长的垂直矩形上，周围还有其他4G网站。5G T-Mobile网站允许这种高频段的毫米波将频谱降下来，如果你在它附近，就能获得更快的速度。

So what is 5G anyway? It’s the next generation or G of cellular service. 2G was more focused on text messaging. 3G was sort of the boom of apps. 4G introduced faster speed so it could handle Uber or FaceTime. Now 5G is supposed to be 10 times as fast and it will be able to support self driving cars, robotic surgeries, even toothbrushes that can tell you when you’re sick.

5G到底是什么?它是下一代移动电话服务。2G更专注于发短信。3G技术促进了手机应用。4G引入了更快的速度，它可以处理Uber或FaceTime。现在5G的速度应该是现在4G网络的10倍，它将能够支持自动驾驶汽车、机器人手术，甚至牙刷可以告诉你何时生病的。

T-Mobile’s 5G network is only in a few cities for now but it has an aggressive plan to roll out to the rest of the country by next year. AT&T, CNN’s parent company is more focused on helping businesses and Verizon is all about speed. But I quickly noticed staying on its 5G network was a challenge.

T-Mobile的5G网络目前只在几个城市部署，但该公司有一个雄心勃勃的计划，计划在明年之前推广到中国其他地区。CNN的母公司美国电话电报公司(AT&T)更专注于帮助企业，而Verizon则专注于速度。但我很快注意到，继续使用它的5G网络是一个挑战。

Sprint had the most seamless coverage giving me a glimpse to what life with 5G can really look like but it also had slower speeds than some of the other providers. You can see how close we are to the 5G cell site right there in the building above the Starbucks, but I can’t even get on the network. I’m just only a couple 100 feet away. Oh wait, OK. I got it. We did a test on T-Mobile’s 4G and 5G connections in the park.

Sprint拥有最全面的覆盖，让我得以一窥5G的真实生活，但它的速度也比其他一些提供商慢。你可以看到我们离5G基站有多近,它就在星巴克楼上，但我甚至连网络都上不了。我就在几百英尺外。哦,等一下,好了。我连上了。我们在公园里测试了T-Mobile的4G和5G连接。

The 5G network was significantly faster but it didn’t quite hit the high speeds I saw on other networks. So I’m getting really great 5G service right here at the Starbucks and the 5G cell site is right above me but let’s see what happens if I go inside. And there we go, just - - it just dropped just now. Some people might think that their already using 5G.

5G网络的速度要快得多，但还没有达到我在其他网络上看到的那种高速。所以我在星巴克得到了很好的5G服务，5G手机网站就在我的正上方，但是让我们看看如果我进去会发生什么。好了，有信号了。有些人可能认为他们已经在使用5G了。

On my phone actually it says 5GE which stands for 5G Evolution. You’re using a much faster network but you’re not actually using 5G. That’s actually because you need one of these phones. This is a Samsung 5G phone. It costs $1,300. There are other options on the market too.

我的手机上写的是5GE，代表5G发展。你正在使用一个更快的网络，但实际上你并没有使用5G。那是因为你需要一部这样的手机。这是三星的5G手机。它花费1300美元。市场上还有其他选择。
