    对行将到来的5G期间,你须要晓得这些
    宣布时辰:2019-07-04 15:07:12   来历:本站首创   点击量:
    In 2019, a big technology shift will finally begin. It’s a once-in-a-decade upgrade to our wireless systems that will start reaching mobile phone users in a matter of months.
    2019年,一场严重的手艺变更终究要起头了。这是咱们的无线体系十年一次的进级,将在几个月内起头涉及手机用户。
     
    But this is not just about faster smartphones. The transition to new fifth-generation cellular networks — known as 5G for short — will also affect many other kinds of devices, including industrial robots, security cameras, drones and cars that send traffic data to one another. This new era will leap ahead of current wireless technology, known as 4G, by offering mobile internet speeds that will let people download entire movies within seconds and most likely bring big changes to video games, sports and shopping.
    但这不只仅是让智妙手机变得更快那末简略。向新的第五代蜂窝收集(简称5G)的过渡,还将影响良多其余范例的装备,包含产业机械人、保安摄像头、无人机和彼此发送交通数据的汽车。经由过程供给能让人们在几秒钟内下载整部片子,并很有能够给电子游戏、体育和购物带来庞大变更的挪动互联网速率,这个新期间绝对以后的无线手艺——即4G——是一次奔腾。
     
    Officials in the United States and China see 5G networks as a competitive edge. The faster networks could help spread the use of artificial intelligence and other cutting-edge technologies.
    美国和中国的官员们视5G收集为一种合作上风。更快的收集能够赞助传布野生智能和其余******手艺的操纵。
     
    Expect to hear more about 5G soon at events like the big consumer electronics trade show CES in January in Las Vegas and MWC Barcelona (formerly the Mobile World Congress) in February in Spain. Wireless service providers including AT&T and Verizon are already talking up 5G. And device makers are previewing gadgets that will work with the technology.
    在1月拉斯维加斯的大型花费电子展会CES和2月巴塞罗那天下挪动通讯大会(MWC)如许的勾当中,估计很快***能领会更多对5G的信息。包含AT&T和威瑞森(Verizon)在内的无线bob官方下载地址 供给商已在议论5G。装备制作商正在展望试与该手艺配套的装备。
     
    Samsung recently demonstrated prototypes of 5G smartphones that are expected to operate on both Verizon and AT&T networks. Many other manufacturers are racing to follow suit, though Apple is not expected in the initial 5G wave. Analysts predict that iPhones with the new technology won’t arrive until 2020. An Apple spokeswoman declined to comment.
    三星(Samsung)***近展现了估计会在威瑞森和AT&T收集上运转的5G智妙手机样机。良多其余制作商正在竞相跟进,固然苹果(Apple)估计不会呈此刻***初的5G海潮中。阐发师展望,接纳新手艺的iPhone将直到2020年才会到来。苹果讲话人谢绝置评。
     
    Here’s what you need to know.
    这里是你须要晓得的工具。
    What exactly is 5G?
     
    5G事实是甚么?
    Strictly speaking, 5G is a set of technical ground rules that define the workings of a cellular network, including the radio frequencies used and how various components like computer chips and antennas handle radio signals and exchange data.
    严酷来讲,5G是一套手艺根本法则,它界说了蜂窝收集的任务体例,包含操纵的无线电频次和电脑芯片和天线等各类组件若何处置无线电旌旗灯号和互换数据。
     
    Since the first cellphones were demonstrated in the 1970s, engineers from multiple companies have convened to agree on new sets of specifications for cellular networks, which are designated a new technology generation every decade or so. To get the benefits of 5G, users will have to buy new phones, while carriers will need to install new transmission equipment to offer the faster service.
    自从20世纪70年月手机******被演示以来,来自多家公司的工程师***已堆积起来,***蜂窝收集的新一套标准告竣分歧,即蜂窝收集每十年摆布被指定为新一代手艺。为了取得5G的产物功能,用户将不得不采办新的手机,而经营商将须要装置新的传输装备以供给更快的bob官方下载地址 。
     
    How fast will 5G be?
    5G有多快?
     
    The answer depends on where you live, which wireless services you use and when you decide to take the 5G plunge.
    谜底取决于你糊口在那里、你操纵哪一种无线bob官方下载地址 和你甚么时辰决议测验考试操纵5G。
    Qualcomm, the wireless chipmaker, said it had demonstrated peak 5G download speeds of 4.5 gigabits a second, but predicts initial median speeds of about 1.4 gigabits. That translates to roughly 20 times faster than the current 4G experience.
    无线芯片制作商高通公司(Qualcomm)称5G的下载速率峰值能够到达每秒4.5千兆比特,但估计初始中值速率约为1.4千兆比特。这相称于今朝4G休会的约莫20倍。
     
    The 5G speeds will be particularly noticeable in higher-quality streaming video. And downloading a typical movie at the median speeds cited by Qualcomm would take 17 seconds with 5G, compared with six minutes for 4G.
    5G速率在高品质流媒体视频中特别惹人注视。按照高通所称的中值速率,下载一部惯例巨细的片子用5G只要17秒,而4G须要6分钟。
     
    Rather than remembering to download a season of a favorite TV show before heading to the airport, for example, you could do it while in line to board a plane, said Justin Denison, a Samsung senior vice president.
    三星******副总裁贾斯汀·丹尼森(Justin Denison)说,你不用在前去机场前,记取下载好某一季***爱好的电视节目,你能够在比方列队登机时下载。
     
    Is that the only speed that matters?
    这是******主要的速率吗?
     
    No. There’s another kind of speed, a lag known as latency, that may become even more important with 5G.
    不是。另有另外一种速率,被称为提早的滞后题目,这个在5G上能够加倍主要。
     
    Issue a command now on a smartphone — like starting a web search — and the response isn’t exactly immediate. A lag of 50 to several hundred milliseconds is common, partly because signals often must pass between different carrier switching centers; 5G, which uses newer networking technology, was designed to reduce latency down to a few milliseconds. It was also designed to deliver signals more reliably than earlier cellular networks, which today frequently drop bits of data that aren’t essential for tasks like watching movies on a phone.
    以后在智妙手机上收回一条指令——比方开启网页搜刮——获得的呼应切当来讲并不是立即的。提早50至几百毫秒很罕见,局部是由于旌旗灯号凡是要在差别的经营商互换中间之间通报;5G接纳了更新的收集手艺,被设想用于将提早降至几毫秒。它还被设想用于比早前的蜂窝收集更******地传输旌旗灯号,后者此刻在一些并非不可或缺的操纵中,比方在手机上看片子,是常常会丢掉一些数据的。
     
    That improvement could bring many benefits, notably in fields such as virtual reality. The highest-quality VR applications now typically require bulky headsets that are connected by wire to nearby personal computers that generate 3D images. With 5G, that would be off-loaded wirelessly to other machines, freeing users to move and making it easier to develop goggles the size of eyeglasses, said Cristiano Amon, president of Qualcomm’s semiconductor business.
    这类改良可带来良多益处,比拟明显的是在假造实际这类范畴。******品质的假造实际操纵此刻普通都要装备轻巧的头具,以有线体例接到四周天生3D图象的小我计较机上。高通半导体营业总裁克里斯蒂亚诺·阿蒙(Cristiano Amon)说,有了5G***能够无线毗连到别的机械上,操纵户能够自在挪动,也能够更轻易开收回眼镜巨细的目镜。
     
    In the related field of augmented reality, people could point a smartphone camera at a football game and see both live video on the display and superimposed player statistics or other data, said Patrick Moorhead, an analyst at Moor Insights & Strategy.
    穆尔征询和计谋公司(Moor Insights & Strategy)阐发师帕特里克·穆尔黑德(Patrick Moorhead)说,在加强实际(AR)的相干范畴,人们能够用智妙手机的摄像头对准一场足球比赛,在显现屏上观看直播视频的同时,能够看叠加的球员统计数据或别的数据。
     
    And 5G’s impact extends to medicine and other fields that increasingly rely on high-speed connections.
    5G的影响还涉及医疗及别的日趋依靠高速毗连的范畴。
     
    “If you talk about remote surgery or connected cars, you don’t want latency times to be too long,” said Fredrik Jejdling, an executive vice president at Ericsson, a maker of cellular equipment.
    “要说到长途手术或联网汽车,你可不想有太多提早,”手机装备制作商爱立信公司(Ericsson)履行副总裁弗雷德里克·杰德林(Fredrik Jejdling)说。
     
    When will 5G be here?
    5G甚么时辰会到来?
     
    The answer for smartphone users in the United States appears to be by the second quarter of 2019; precise timing is uncertain.
    对美国的智妙手机用户,谜底仿佛是在2019年******季度;切当时辰尚不肯定。
     
    Countries expected to follow the United States with 2019 rollouts of 5G include Britain, Germany, Switzerland, China, South Korea and Australia, according to a timetable compiled by Qualcomm.
    按照高通公司体例的时辰表,估计2019年将在美国以后于推出5G手艺的国度包含英国、德国、瑞士、中国、韩国和澳大利亚。
     
    Will consumers see the full benefits of 5G?
    花费者能充实享用5G的优胜吗?
     
    Verizon and AT&T will introduce their 5G offerings with the first use of high frequencies that are known by the phrase “millimeter wave.” Using this, the wireless providers can pump data at high speeds, but the signals don’t travel as far. So the two carriers are expected to first target densely populated areas — “parts or pockets” of cities, as AT&T’s Fuetsch put it.
    威瑞森和AT&T将在它们的5G产物中******操纵称为“毫米波”的高频手艺。操纵这一点,无线bob官方下载地址 供给商能够高速传输送数据,但旌旗灯号能传输的间隔无限。是以,估计这两家经营商将起首对准生齿麋集的地域——用AT&T的安德烈·富奇(Andre Fuetsch)的话来讲,***是都会的“局部地域”。
     
    Sprint and T-Mobile plan to start with lower frequencies. The result may be somewhat slower initial speeds but broader range, said Michael Thelander, president of Signals Research, a wireless consultancy.
    Sprint和T-Mobile打算从较低的频次起头。无线征询公司旌旗灯号研讨(Signals Research)的总裁迈克尔·泰兰德(Michael Thelander)说,成果能够是初始速率有所减慢,但笼盖规模更广。
     
    Still, 5G’s full benefits aren’t expected until U.S. carriers upgrade key central switching equipment, which may not happen until late 2019 or sometime in 2020.
    不过,5G的全数益处估计要比及美国的经营商进级焦点互换装备以后能力完成,而这能够要到2019年末或2020年的某个时辰。
     
    So should I buy a smartphone that works with 5G right away?
    我是不是应当顿时买一台撑持5G的智妙手机呢?
     
    You have a lot to consider. For example, while Verizon and AT&T plan to later add 5G services based on lower frequencies that offer wider coverage, the first 5G handsets may not work with those portions of their networks. So the reach of 5G signals for those phones may remain limited.
    你须要斟酌良多任务。比方,固然威瑞森和AT&T打算稍后增添基于低频的5Gbob官方下载地址 ,供给更普遍的笼盖规模,可是******批5G手机在其该局部收集下能够没法一般任务。是以,这些手机的5G旌旗灯号规模能够依然受限。
     
    “I wouldn’t buy a 5G phone until it supports 5G in one of the lower-frequency bands,” Mr. Thelander said. “For all operators but Sprint, this means at least late 2019, and more likely 2020.”
    “在5G手性能撑持较低频段的5G收集之前,我不会采办它,”泰兰德说。“对除Sprint以外的一切经营商,这象征着最少要在2019年末,更有能够会是在2020年。”
