The buzz around 5G has been heating up lately, and for good reason. We're finally starting to see the first widespread 5G network deployments, and 2020 promises to bring a host of 5G phones, including the first budget and midrange models. There's a chance that if you buy a new phone this year, it will support 5G.
圍繞5G的熱潮最近已經升溫，而且理由很充分。我們終於開始看到第一個廣泛的5G網絡部署，2020年有望帶來大量5G手機，包括第一個預算和中檔機型。如果你今年買了新手機，就有可能支持5G。
But what can you really expect from 5G in 2020? The technology's quite new, and there aren't too many "killer applications" just yet. We've separated fact from fiction for you in this list of eight things you need to know about 5G right now.
但是，你能對2020年的5G有什麼期待呢?這項技術非常新，目前還沒有太多的“殺手級應用”。我們已經為你把事實和謠言分開了，現在你需要知道關於5G的八件事。
1. Superfast 5G is still a novelty
Before you get all excited about multi-gigabit 5G speeds on your shiny new 5G phone, chances are you won't see them very much, if at all, during 2020. These speeds require a technology known as mmWave, which operates at extremely high frequencies. At these higher frequencies, radio signals can't travel as far from towers, requiring "mini-towers" every so many blocks to provide a stable connection. This means these connections may be limited to the big cities and often only in select neighborhoods, as they'll take a little longer to build.
1.超快的5G仍然是個新鮮事物
在你對你閃亮的新5G手機上的千兆5G速度感到興奮之前，你可能不會經常看到它們，如果有的話，在2020年。這些速度需要一種稱為mmWave的技術，它在極高的頻率下工作。在這些更高的頻率下，無線電信號無法從發射塔傳輸到很遠的地方，因此每隔這麼多街區就需要一個“迷你塔”來提供穩定的連接。這意味著這些聯繫可能僅限於大城市，通常只在特定的社區，因為它們需要更長的時間來建立。
2. You might not notice much of a difference at first
Even in areas where 5G coverage is more expansive (and lower frequencies are being used to provide it), you might find yourself hard-pressed to notice a difference in download speeds. While many of us will see a definite speed bump into the hundreds of megabits per second (especially those using T-Mobile's 5G network, which uses low-band, 600MHz signals), it won't be that much of a jump in overall performance this year. Think evolutionary rather than revolutionary. That's because carriers are pairing 4G and 5G networks to speed deployments, and concentrating on breadth of coverage rather than speeds. But when networks get tuned for speed, watch out!
2.一開始你可能不會注意到有什麼不同
即使在5G覆蓋範圍更廣的地區(低頻率正在被用來提供5G覆蓋)，你可能也很難注意到下載速度的差異。雖然我們中的許多人會看到每秒數百兆比特的速度明顯提高(尤其是那些使用T-Mobile的5G網絡的人，該網絡使用的是低頻段、600MHz的信號)，但今年總體性能不會有太大提升。認為是進化而不是革命。這是因為運營商正在將4G和5G網絡配對以加快部署速度，而且專注於覆蓋範圍而非速度。但是，當網絡調整為速度時，要小心!
3. There won't be a killer app
Despite the claims of how 5G will change the way we live improving our gaming, transforming our cars, and more we all need to take a step back and realize that we're only in year two of a journey that will likely take most of the decade. LTE took nearly a half-decade before networks were robust enough to provide reliable, broad-based coverage and some rural areas still don't have LTE nearly a decade later. Similarily, 5G likely won't take as long thanks to advancements in wireless technology, but still, the idea of connected cars and always-on IoT devices is still many years away.
3.不會有一個殺手級的應用程序
儘管有人聲稱5G將改變我們的生活方式、改進我們的遊戲、改造我們的汽車，但我們都需要退一步，意識到我們才剛剛開始兩年的旅程，這段旅程可能會花費十年的大部分時間。LTE經歷了近5年的時間，才有了足夠強大的網絡來提供可靠、廣泛的覆蓋，而近10年後，一些農村地區仍然沒有LTE。同樣，由於無線技術的進步，5G可能不會花那麼長的時間，但聯網汽車和永遠在線的物聯網設備的想法仍然需要很多年才能實現。
4. 5G phones will actually be affordable
While we did see quite a few 5G phones announced during 2019, there weren't many that we could honestly call "affordable." Most of these phones retailed for $1,000 or more. For 2020, Samsung set the bar with the new Galaxy S20, which starts at $1,000. But other phone makers are keeping prices surprisingly low: LG promises that the V60 ThinQ 5G will be under $1,000, for example, while the OnePlus 7 5G is around $800. This should improve during the year, but they'll still remain close to that $1,000 price point. With cheaper 5G chipsets on the way from Qualcomm, there should be more options later in the year as well.
4.5G手機將會變得更加便宜
雖然我們確實在2019年看到了不少5G手機的發佈，但說實話，我們並沒有多少可以被稱為“負擔得起”的手機。這些手機的零售價大多在1000美元以上。到2020年，三星推出了全新的Galaxy S20，起價1000美元。但其他手機制造商出人意料地保持低價:例如，LG承諾，V60 ThinQ 5G的價格將低於1000美元，而一加75g的價格在800美元左右。這在今年應該會有所改善，但它們仍將接近1000美元的價位。隨著更便宜的5G芯片組即將從高通(Qualcomm)轉移到中國，今年晚些時候應該也會有更多選擇。
5. Cable internet will finally have a competitor
While using 5G on a mobile device might be a bit of a challenge in 2020, the idea of using 5G as a fixed internet option will grow this year. We fully expect to see a host of 5G hot spots during the year, and many carriers have either indicated or announced that they plan to offer home 5G options. Even with "slower" 5G options, the speeds will be roughly the same as a standard cable internet connection. We can only hope this competition helps to bring prices down.
5.有線網絡終於有了一個競爭對手
雖然在移動設備上使用5G在2020年可能有點挑戰，但將5G作為固定互聯網選項的想法今年將會增長。我們完全預計今年會出現大量5G熱點，許多運營商已經表示或宣佈，他們計劃提供家庭5G選擇。即使有“更慢”的5G選擇，速度也將大致與標準的有線互聯網連接相同。我們只能希望這次競爭有助於降低價格。
6. 5G will find its way into everything
CES 2020 brought us a host of 5G laptop announcements, but laptops are only the tip of the iceberg when it come to 5G. With the cost of 5G chips on the way down, electronics manufacturers will begin building 5G into a wide variety of electronics. Expect tablets and even smart devices to gain 5G support during the year. A word of warning, however: Like the first phones, these devices will also be initially expensive but it's a sign that the often-hyped connected future of 5G is becoming a reality.
6.5G將在所有領域找到出路
在2020年的消費電子展上，我們看到了大量關於5G筆記本電腦的宣傳，但談到5G，筆記本電腦只是冰山一角。隨著5G芯片的成本不斷下降，電子產品製造商將開始把5G打造成各種各樣的電子產品。預計今年平板電腦甚至智能設備將獲得5G支持。然而，需要提醒的是:和第一代手機一樣，這些設備最初也會很貴，但這是一個信號，表明經常被炒作的5G互聯未來正在成為現實。
7. 5G will be in the news a lot
As 5G rolls out during 2020, expect the technology to be in the headlines with ever-increasing regularity. Not all of it will be positive, however. Municipalities are becoming frustrated by the Federal Communications Commission's push to streamline the approval process for the mini-towers that will make 5G's superfast connections tick, and there will be continuing critiques of 5G's "safety," even though an international panel of experts say 5G is safe. Still, 5G will change our lives. It's not a question of if, but when.
7.5G將會經常出現在新聞中
隨著2020年5G的推出，預計這項技術會越來越頻繁地出現在新聞頭條上。然而，並不是所有的結果都是積極的。聯邦通信委員會正努力簡化迷你塔的審批流程，以使5G的超高速連接正常運行，市政當局對此感到失望。儘管一個國際專家小組表示，5G是安全的，但仍會有人繼續批評5G的“安全性”。然而，5G將改變我們的生活。這不是如果的問題，而是何時的問題。
8. 5G is safe
Despite the claims of its detractors, 5G is safe. After numerous studies, including one that involved an international panel of experts, there is no concrete evidence that radiation from 5G phones poses any more risk than your standard cell phone. So, no, your 5G device will not irradiate you, and it's completely safe to use.
8.5g是安全的
儘管批評者聲稱5G是安全的。經過大量研究，包括一項涉及國際專家小組的研究，沒有具體證據表明5G手機的輻射比普通手機造成的風險更大。所以，你的5G設備不會輻射 你，使用它是完全安全的。
