5G無線網絡:速度並不是全部

When it comes to the wireless networks of the future, speed won't be everything.

一提到未來的無線網絡，速度並不能代表全部。

The advent of so-called 5G, or fifth-generation, wireless technology will bring incredible speed, for sure, with the industry aiming to see your network connection jump by 100 times. (Yes, 100.) More importantly, the network will be smart enough to act differently depending on how it's accessed, whether from a heart monitor when you're relaxing at home or from a self-driving car zipping down a crowded highway.

5G，或者說第五代無線技術的到來，無疑會帶來難以置信的速度體驗，目標是讓你的網絡連接速度快100倍。（是的，100倍）。更重要的是，網絡將變得十分只能，以至於可以在不同的場合運作。無論你在家中放鬆，還是沿着擁擠的街道開車，都可以通過中心操控器接入。

That's according to Hans Vestberg, CEO of Ericsson, one of the world's largest suppliers of telecommunications equipment.

世界最大的電子通訊設備提供商之一Ericsson的總裁Hans Vestberg說。

His comments provide a glimpse into what tomorrow's wireless network will look like. While carriers around the world are still deploying 4G networks, which have brought broadband speeds over the air, there's increasing chatter about what's next. In the US, Verizon Wireless has already said it plans to field-test its own take on 5G next year, and the industry is starting to talk about the new kinds of devices and connected services that will spring from the technology.

他的言論讓我們一睹未來的無線網絡是怎樣的。當世界各地的服務商還在部署寬帶速度超過光速的4G網絡的時，關於下一步是什麼的呼聲已經在增長。在美國，Verizon無限公司已經宣稱，計劃在明年實驗自己研發的5G，這一產業技術將引發新種類裝置和連接服務的探討。

"Many industries will look at how 5G will transform their business," Vestberg said in an interview on Friday. "It's my job to build a network to handle that."

Vestberg在週五的見面會上說，“很多產業將會目睹5G怎樣改變他們的商業。我的工作就是建立一個可以處理這一個問題的網絡”。

As fast as Verizon is moving, the industry isn't expected to invest in the technology in earnest until 2020. The speed and capacity 5G brings could offer a legitimate alternative to the physical connection available via Internet service providers and companies such as Google, which use fiber optics to deliver super-high speeds. 5G is supposed to be even faster.

儘管Verizon正以最快的速度開發5G網絡，但是正式的技術投資直到2020年纔有望實現。5G的速度和容量可以提供一種合法的選擇，要不通過互聯網服務提供商進行物理連接，要不通過像谷歌一樣使用光纖來實現高速的公司。5G預計速度更快。

Depending on the device, 5G may have a range of behaviors, he said. The network has to be responsive enough to tell a self-driving car where to go and how to react to situations that require a split-second reaction. It has to be consistent enough to maintain a connection with a hypothetical chipset in your body that can monitor your vitals, but know to instantly ping emergency services in case something goes wrong. It also has to operate efficiently enough that farms can use sensors that can ping the network for 10 years on a single charge.

依靠設備，5G可能擁有很多性能。互聯網必須反應足夠靈敏，可以高速自駕車去哪裏以及怎麼樣對需要瞬間反應的情況作出應對。它必須擁有足夠的連貫性，可以和監控你生死攸關事項的體內假想芯片保持聯繫，但是也懂得萬一出現緊急情況時，立即開啓緊急服務。它同樣必須有效地運轉，農民可以在十年內使用可以連接互聯網的傳感器並且不更換電池。

In other cases, 5G wireless technology may replace the broadband service coming into your home via wires or cables, Vestberg said. It's already happening with 4G in some parts of the world, but 5G adds higher speed and capacity. With 5G, carriers could also deliver super-sharp 4K video to the home.

Vestberg說，在其他情況下，5G無線技術可以替代通過電線進入你家的寬帶服務。這一服務已經在部分使用4G的地區實現，但是5G的速度更快，容量更大。通過5G，運營商可以向住戶家提供高清4K視頻。

One of the reasons Verizon is holding its test so early is to figure out what kinds of applications can take advantage of 5G, the New York-based telecommunications company said in September.

九月，美國電訊公司稱，Verizon提早開始試驗的原因之一是爲了找出哪些途徑可以利用5G。

Vestberg declined to comment on the plans of his carrier customers, but noted that there was a cost to building out these networks, with players such as ATT projected to spend roughly $10 billion this year. He also warned that as capacity and speeds have increased, so too has usage.

Vestberg拒絕評論他們重要客戶的計劃，但是強調，建設這些網絡需要花費很多錢，像AT&T這樣的合作商今年預計要花費大約100億美金。它同樣提醒，一旦速度和容量提升了，使用量也會提升。
