4. 5G商用
commercialization of 5G

請(qǐng)看例句：

The fifth generation (5G) of cellular networks may be put into commercial use as early as 2020. Industry analysts believe that the commercialization of 5G network will bolster the telecom industry and emerging sectors such as big data, cloud computing and artificial intelligence.
第5代(5G)蜂窩網(wǎng)絡(luò)可能最早于2020年投入商用。業(yè)內(nèi)分析人士認(rèn)為，5G網(wǎng)絡(luò)商用將促進(jìn)電信產(chǎn)業(yè)和大數(shù)據(jù)、云計(jì)算、人工智能等新興領(lǐng)域的發(fā)展。

根據(jù)工信部(the Ministry of Industry and Information Technology)、中國(guó)IMT-2020(5G)推進(jìn)組(promotion group)的工作部署以及三大電信運(yùn)營(yíng)商(three major telecom operators)的5G商用計(jì)劃，我國(guó)將于2017年展開(kāi)5G網(wǎng)絡(luò)第二階段測(cè)試(second-phase testing)，2018年進(jìn)行大規(guī)模試驗(yàn)組網(wǎng)，并在此基礎(chǔ)上于2019年啟動(dòng)5G網(wǎng)絡(luò)建設(shè)(the construction of a 5G network will begin in 2019)，最快在2020年正式商用5G網(wǎng)絡(luò)(officially put 5G network into commercial use as early as 2020)。

根據(jù)目前的技術(shù)發(fā)展趨勢(shì)，5G將形成全球統(tǒng)一融合的單一標(biāo)準(zhǔn)(a single unified global standard)。國(guó)內(nèi)外廠商在5G領(lǐng)域的競(jìng)爭(zhēng)也日趨激烈(increasingly fierce competition in 5G among manufacturers home and abroad)，手機(jī)芯片制造商高通(mobile chip maker Qualcomm)正在加快5G手機(jī)芯片的研發(fā)，此前高通已公布全球首個(gè)5G基帶(baseband)。今年年中，瑞典愛(ài)立信與韓國(guó)SK電信、德國(guó)電信等電信運(yùn)營(yíng)商合作開(kāi)展了全球首例橫貫大陸的5G測(cè)試(Sweden's Ericsson partnered with South Korea's SK Telecom, Germany's Deutsche Telekom and other telecom operators to deploy the world's first transcontinental 5G trial network)。諾基亞和上海貝爾也表示，已正式完成重要的5G技術(shù)開(kāi)發(fā)和驗(yàn)證，目前正在根據(jù)用戶需求，開(kāi)發(fā)相應(yīng)的5G網(wǎng)絡(luò)解決方案。此外，上述電信設(shè)備制造商還推出了包括車聯(lián)網(wǎng)(in-car networking)、無(wú)人機(jī)(drone/unmanned aerial vehicle)、智能家居(smart home/intelligent home control system)、智慧城市(smart city)等多項(xiàng)5G應(yīng)用和解決方案，在具體的商用領(lǐng)域具有不小的優(yōu)勢(shì)。
