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。 So it could even replace your home's 所以它甚至可以取代你的 current high-speed internet service. 家用網路。 The new standard means devices 新的標準的意思是 can communicate with each other with no lag. 裝置之間可以沒有延遲的相互溝通。 You know how when you write with a pen, 你知道當你用筆在寫東西時, you see it as it happens? 它們是同步發生的嗎? That's zero latency. That's pretty much 零延遲。那就是 5 G 厲害的地方, what 5G can do: no waiting. 不用等它。 That opens up the possibility for things like 這也開啟了一些可能性, wireless VR experiences and more reliable driverless cars 像是虛擬實境體驗以及更多的自動駕駛的車子, thanks to the ability to analyze 多虧它有快速分析與處理資料 and process data at faster speeds. 的能力。 It's an exciting time for faster, more connected devices. 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. 首先,我們需要一整個基地建設。 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, 比 4G 傳輸大量資料時還要快, but it also means a much shorter range. 但也意味著傳輸距離比較短。 4G wavelengths have a range of about 10 miles. 4G 的波長有 10 英里長。 5G wavelengths have a range of about 1,000 feet, 5G 的波長有 1,000 英尺長, not even 2% of 4G's range. 範圍卻不到 4G 的 2%。 So to ensure a reliable 5G signal, there needs to be 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. 密度是涉及到每個路燈,紅綠燈…等 because even trees can block 5G signals. 因為就連樹都有可能阻饒 5G 的訊號。 5G isn't gonna be cheap. 5G 可能會很貴。 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, 都需要連到在一起, 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. 但他們有說會再做進一步的調查。 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 那如果說電信業者順利地在你的地區架設了 installed all the equipment around you. 這些基地臺設備。 You still need devices that can run 5G. 你仍然還是需要 5G 的手機才能使用。 So far we're only seeing a few that can do that. 目前為止只有少數幾台的手機可以使用 5G。 In the US, the only smartphones that we know about 在美國,我們知道的 5G 手機 that have 5G is the Moto Z3 if you buy the extra Moto mod. 有 Moto 的 Z3,前提是要額外購買它的 5G 模組背蓋。 There's also the Samsung Galaxy S10 5G 還有 Samsung Galaxy S10 的 5G 手機 and also the LG V50 ThinQ. 與 LG 的 V50 ThinQ 手機。 And you can expect 5G phones 5G 的手機比那些沒有 5G 的手機 to cost you about $200 to $300 more than one without 5G. 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 所以,碰巧你是那些有現在已經有 5G 設備的人, who has access to 5G right now, enjoy it. 好好享受。 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。
