    緩慢的?

  • This fifth-generation cellular network

    這第 5 代的行動網路,

  • is 10 times faster than 4G LTE.

    是比第 4 代的技術還要快上 10 倍。

  • That means instead of waiting

    這意味著在 Netflix 平台上,

  • five minutes to download a movie on Netflix in 4G,

    不用再透過 4 G 苦等 5 分鐘才下載一部片,

  • it will take just 30 seconds on 5G.

    透過 5 G 只需要 30 秒。

    更多的裝置能夠更快的連結,這真是令人興奮的時代。

  • But there are some obstacles 5G needs to overcome

    但在我們享受到這些好處前,

  • before we can really reap all of its amazing benefits.

    5 G 仍然有些障礙要克服。

  • First, we need a whole new infrastructure.

  • Your cell phone provider, for example, will need to

    像是你手機的電信業者,他們需要為這新的科技

  • install a lot of new equipment for this new technology

    安裝一整套全新的設備。

  • because 5G uses a totally different wavelength

    因為 5G 使用的波長與標準 4G 的

  • than the 4G standard your phone currently uses.

    完全不相同。

  • The 5G standard uses millimeter waves,

    標準 5G 採用的是毫米波,

  • which are a lot shorter than the wavelengths 4G uses.

    比起 4G 用的波長短許多。

  • The shorter wavelength means 5G

    較短的波長意味著 5G

  • can carry a lot of data much faster than 4G,

    為了要確保可靠的 5G 訊號,每個地方都必須要有

  • a lot of 5G cell towers and antennas everywhere.

    5G 的行動基地臺與天線。

  • We're talking on every lamppost, traffic light, etc.

  • You know, each node, or mini cell tower,

    你知道的,每個截點,或是迷你基地臺,

  • needs some kind of connection to it,

  • and that means laying down fiber optic cables,

    還有埋地下的光纖纜線,

  • and, you know, it's still an undertaking,

    你知道的,一切都還在進行當中,

  • and it's definitely not in the millions.

    百來萬的資金肯定是不夠,

  • It's definitely in the billions,

    肯定要好幾十億,

  • possibly hundreds of billions.

    也有可能要幾千億。

  • Not only will this cost billions of dollars,

    這件工程不僅需要花幾千億

  • but there's also pushback from many local communities.

    還會受到許多當地居名的反彈。

  • One of the biggest problems they face

    他們面臨最大的難題

  • is actually local governments, local communities,

    是當地政府與當地社區。

  • who don't want these carriers to build towers

    他們不想讓電信業者

  • or antennas all over the place.

    到處都架設基地台與天線。

  • Or maybe they're afraid of the health risks,

    或者他們害怕會有健康上的風險,

  • which is another big concern.

    這卻是另一個很大的擔憂。

  • Some are concerned

    有些人擔心 5G 會有

  • that 5G radiation may cause cancer.

    致癌的問題。

  • The FCC so far has said that there aren't any problems

    聯邦通信委員會目前表示 5G 的輻射

  • or concerns with 5G radiation,

    不會有任何的問題,

  • but they have said they still need to do more research.

  • Despite all that, Verizon already rolled out

    儘管如此,Verizon 公司已經開始

  • the beginnings of its 5G network

    在芝加哥與明尼阿波利斯部分地區,

  • to parts of Chicago and Minneapolis.

    展開 5G 網路的鋪陳。

  • AT&T currently has about 19 cities with 5G capabilities,

    AT&T (固網電話服務供應商),已在 19 個城市提供 5 G 的服務,

  • and Sprint and T-Mobile say they'll be releasing

    Sprint 與 T-Mobile 公司也說在 2019 年,

  • their 5 G network sometime in 2019.

    也會開放 5G 的服務。

  • So while 5G is being rolled out,

    在 5G 展開的同時

  • it is very slow and in limited areas,

    因為 5G 的距離範圍太短,進展也是非常的緩慢,

  • and noncity and rural areas will be more difficult to cover

    在受限的地區,像是非城市與鄉下地區都要被覆蓋到,

  • since 5G has such a short range.

    是相當困難的。

  • But let's say your internet provider successfully

    可能還會要你多花上 200 到 300 美元。

  • Verizon and Starry are also getting a head start

    Verizon 與 Starry 公司會提早一步

  • in bringing 5G to your home internet.

    提供你 5G 的家用網路。

  • So if you're one of the few people

  • One of the things I'm really excited about with 5G,

    5G 的所有好處裡令我比較興奮的是

  • 5G is said to be a super open highway

    5G 是條高速公路

  • with many, many more lanes than the 4G LTE highway.

    他的車道數量遠多過於 4G 的高速公路。

  • Which means a lot less congestion, even during peak hours.

    這也意味著不容易塞車,即便是在尖峰時段。

  • I do estimate that eventually even 5G will be congested

    我預估當 5 G 開始普及化時,

  • with the number of people connecting to it

    大眾與大眾設備都能普遍使用 5G 網路,

  • and also the extra stuff that's gonna be used for 5G.

    那即便是 5G 也會因此塞車。

  • At which point, we're gonna have to step over to 6G.

    到那個時候,我們叫要前進到 6G。

  • So while all the carriers

    所有電信業者

  • are already starting to tout their 5G capabilities,

    都已經開始宣傳自家的 5G 網路,

  • don't get too excited because it's

    但別高興得太早,

  • still going to be a few years before

    因為它還需要花上幾年的時間,

  • you can really take advantage of it.

    才能享受到它帶來的好處。
