There has been a lot of publicity recently surrounding 5G,the next generation of wireless technology for the world.But what is this technology and how might it change our lives?


最近围绕5G(面向全球的下一代无线技术)进行了大量宣传。但这项技术是什么?它如何改变我们的生活?


5G stands for fifth generation,meaning the next step in the progression of technology to replace the current 4G system.4G was the replacement for 3G,which came after 2G,and so on.


5G代表第五代,这意味着下一步技术进步将取代目前的4G系统。4G是继2G之后的3G的替代品,以此类推。


These systems are wireless computer networks.


这些系统是无线计算机网络。


Earlier"G"systems were designed to improve mobile communication operations.Each new technology brought major improvements in speed and greatly increased network capacity.


早期的“G”系统是为了改进移动通信操作而设计的。每一项新技术都大大提高了速度和网络容量。


The new 5G system promises more of the same.It is expected to permit more users to do more things—at a faster rate.Higher internet speeds and larger network capacity should result in better performance for device users connected to 5G.


新的5G系统承诺会有更多的相同之处。预计它将允许更多的用户以更快的速度做更多的事情。更高的网速和更大的网络容量应该会为连接到5G的设备用户带来更好的性能。


However,technology experts say there is a major way that 5G is different than the earlier systems.It will move well beyond mobile network technology to affect many more devices and industries than other"G"versions.


不过,技术专家表示,5G与早期系统有一个主要的不同之处。它将远远超越移动网络技术,影响比其他“G”版本更多的设备和行业。

When will it be available?

Before we can all use 5G,wireless companies and phone makers will have to complete and deploy a whole new system.New phones and communication equipment must be built.


在我们都能使用5G之前,无线公司和手机制造商必须完成并部署一个全新的系统。必须建造新的电话和通讯设备。


American wireless companies have been preparing for the new system for some time.They have been creating new network equipment and buying broadcasting space to carry 5G signals.They have built new 5G antennas to serve American cities and towns.Wireless providers will invest at least$275 billion in 5G-related networks in the United States,the industry group CTIA reported.


美国无线公司已经为新系统做了一段时间的准备。他们一直在创造新的网络设备,并购买承载5G信号的广播空间。他们建造了新的5G天线,为美国城镇服务。据行业组织CTIA报道,无线运营商将在美国5G相关网络上投资至少2750亿美元。


The first U.S.launch of 5G is expected to happen sometime this year.Industry experts expect it will take a few more years to go nationwide.It will take even longer to reach rural areas.


预计今年某个时候,美国将首次推出5G。业内专家预计,再过几年全国性的推广将是一个艰难的过程。到达农村地区需要更长的时间。


China is expected to launch 5G sometime in 2020,while European nations are likely to build their systems more slowly over time.


预计中国将在2020年的某个时候推出5G,而随着时间的推移,欧洲国家的系统建设可能会更加缓慢。


In the United States,the first 5G-ready phones should be available in the first half of this year.The first 5G iPhone,however,is not expected until 2020.


在美国,首批5G手机应该在今年上半年上市。不过,第一款5G iPhone预计要到2020年才能上市。


4G phones will work on 5G networks,but not at 5G speeds.
