5G时代的城市什么样

2019-05-25 14:08:34 来源: 经济日报
Kulangsu,asmallislandofftheshoreofXiameninFujianprovince,andHohXil,anaturereserveinQinghaiprovince,wereaddedtothkow,,calledKulangsuinthelocaldialectandknownforitswell-preservedhistoricalbuildings,andHolXil,aplateaufamousforitsnaturalbeautyandbiodiversity,Chinanowhas52sitesinscribedontheUNESCOWorldHeritagelist,whichwasestablishedtosafegsrecaponthe52heritagesitesinChina,whichmaygiveyousomecluesonyournexttravelplan.

  当人们刚刚适应了3G到4G的跃升,享受着移动互联带来的新型城市生活时,突然发现,又出现5G了。科技进步的速度总让人惊叹,5G的迎面而来,又将掀开怎样的城市图景,给城市生活带来哪些不一样的变化呢——

  国际通信标准组织3GPP日前公布了第五代移动通信技术5G的官方LOGO,标志着5G时代距离我们又进了一步。从3G到4G,网速的跃升已经让我们的城市生活发生了翻天覆地的变化,一个明显的代表是智能手机日渐成为人们生活乃至工作的中心,从手机导航到手机订餐,从智慧家居到视频会议,4G网速让移动互联网应用飞速发展,让城市生活变得更智能更便捷。

  5G的速度和接入能力更加强大,将跳出移动互联网让万物相连,城市生活包括交通、安防、教育、旅游等各个方面都将变得更加智慧。“5G的速度和接入能力足以满足未来汽车、无人机、机器人等智能终端的需要,是未来万物互联的重要基础,将给消费者带来更多新的体验和感受。”赛迪顾问通信产业研究中心分析师吕婵告诉《经济日报》记者。

  物物相连可实现

  5G峰值速率可达到20Gbps,每平方公里可链接数超过100万,链接延时仅1毫秒……如果要对这些专业数据作一个通俗的描述,那就是未来的5G网络将使得一整部电影一秒钟就能在互联网上下载完毕,而且可用于物联网应用、自动语音翻译服务、超高精细影像服务、3D影像技术服务、家用联网机器人支援服务等。

  高速率让物物相连成为可能。2016年11月,爱立信、韩国SK电讯和宝马实现全球首个多车辆5G测试,在2017年2月又创世界纪录,在170Km/h的进行速度中实现3.6Gbps的下行速率。测试显示的5G性能可以实现多个车联网系统功能,例如增强现实和虚拟现实、障碍物控制和车辆间通信等。

  众诚智库总裁杨帆接受《经济日报》记者采访时表示,4G的强项主要是容量,但传输语音的品质较差,而5G在接取速度、内容品质和功能整合等方面将比4G优越很多,从而让语音、容量和数据都能更好地呈现。因此,5G通信技术可以解决包括视频、语音、即时通信、在线游戏和虚拟现实等多种多媒体元素在内的互动需求。

  “5G技术的首要重点是解决了在频谱资源有限的情况下,仍能达到很高的速度以满足未来行动服务需求。5G网络将提供全新的技术为人与人之间建立联系,当然还包括人与汽车、房屋等之间的联系。而且不管身处何地,这些服务都能马上实现。可以说,5G所实现的功能是更具复原能力的、更加一致的以及更加具备可用性的网络,它不仅要能支持庞大的数据流量,还能以远低于今天的成本来交付联网服务。”杨帆说。

  “5G时代的城市生活、家居及办公环境里各种设备都将是高度智能化、自动化的,各种服务可以根据使用者的喜好个性化定制,同时在出行等很多方面的协同化程度更高。”爱立信5G专家张萌博士向《经济日报》记者进一步描绘说:从清晨开始,智能管家根据你的生物特征在恰到好处的时间用你最喜欢的音乐唤醒你,这时咖啡和早餐已经自动提前准备好了,早餐后无人驾驶的汽车送你去公司,路上的时间你可以打开VR进行远程会议,而不会注意到马路上的交通灯正根据车流量进行在线调整……

  “如果说3G、4G移动通信以及互联网、智能终端的崛起,让通信不再只是满足人类沟通的基本诉求,而是一跃变成主角,改变了娱乐、支付、分享、交友等等的渠道。那么5G将会从更大的范围渗透到人们未来生活的方方面面,不仅仅是提供更高速率,还包括物联网、车联网、工业控制、智慧城市等等。”中兴通讯高级副总裁张建国如是说。

  智慧城市添助力

  “媒体类业务、物联网和云计算技术是目前国内智慧城市建设的主要技术手段,而宽带速率严重影响着这3类技术的广泛应用和快速发展,已经成为智慧城市建设过程中的主要瓶颈之一,5G技术应用将解决这些问题。”杨帆说。

  其中,媒体类业务主要包括视频类、虚拟现实、增强现实等,物联网业务主要包括工业、医疗、交通等万物互联业务,云计算业务则主要是数据存储、应用等。以当下正悄然兴起的虚拟现实为例,目前的主流虚拟现实设备受限于现有的无线网络传输速度和传输时延,通常采用HDMI(高清晰度多媒体接口)线缆连接,这极大地限制了用户的使用范围,影响用户体验。而5G较高的数据传输速率、低时延和较大的通信容量,将使用户摆脱线缆的约束,尽情地享受虚拟现实游戏带来的快乐。

  此外,车联网技术也属于低时延、高可靠应用场景,通过终端直通技术,可以实现在汽车之间、汽车与路侧设备间的通信,从而实现汽车主动安全控制与自动驾驶。公交枢纽站和公交站台还可以把公交汽车、其他汽车、地铁、飞机等交通工具的联网信息整合起来,做成智能出行的指引助手,帮助用户选择用什么方式出行,也可以提供手机实时支付功能,帮助用户购票。 杨帆指出,云计算的发展需要安全的、可信赖的服务运营商支持,这些运营商要在网络方面有丰富的经验,他们将被允许进入云计算平台,并被要求在云计算平台中运用统一的标准创造新的增值服务与体验。这会使终端用户获得更多的即时应用,进而更有效地利用5G网络。云计算将大大减少5G网络发展中的资本投入,这意味着,用户可以花更少的钱买到更多更好的服务。

  张建国则认为,在当下智慧城市的建设中,宽带速率虽然重要,但还不是最关键的。目前有两种物联网的需求场景:一种是高数据速率、超低延迟场景,泛称为宽带物联网;另一种是低数据速率、延迟较大的场景,泛称为窄带物联网。两种场景下的标准均有待完善,而5G有望利用弹性和超密集网络、大数据分析、高安全性的云服务等创新服务于上述两种场景。

  “5G网络可适应不同业务的需求,车联网、自动驾驶、远程机械控制、VR等都有望梦想成真。因而在智慧城市的建设中,5G将发挥重要的作用。”张萌表示,5G时代,更多的机遇将存在于智能手机之外。大众市场的自媒体与个性化游戏,在5G时代会继续发展,并有更普及更广泛体验更好的实现。智能驾驶、智能交通设施、遥控机械等都会在5G时代成为现实。而更加智能的多维度的交互方式,也将在5G时代成为我们的日常。

  5G生活并不远

  5G时代的城市生活何时才能实现呢?据杨帆介绍,我国的5G基础研发试验将在2016年到2018年进行,分为5G关键技术试验、5G技术方案验证和5G系统验证3个阶段。之后将进入5G网络建设阶段,并有望最早在2020年正式商用。

  “目前全球通信业对5G研究和部署的竞赛在逐步加速。5G商用的落地不断推进,商用的提速也在倒逼产业链的跟进。”吕婵说。

  张萌也表示,现在来看5G的发展步伐在加快。美国运营商宣布将在2017年推出5G试商用,韩国计划在2018年冬奥会推出5G商用,日本运营商的目标是在2020奥运会提供5G商用服务,中国也在2017年开始5G技术试验的第二阶段,在2018年进入大规模外场测试。《爱立信移动市场报告》预测,亚太区将成为第二个5G用户增长最快的区域,2022年,10%的用户将为5G用户。

  5G或将提前应用,一个典型的表现是企业纷纷提前布局。“中兴5G技术研究区别于以往3G、4G的一个地方在于,3G、4G都是标准出来之后才开始研发产品,而5G是我们首次在标准发布之前就基于5G的发展方向,率先进行核心技术的研究以及原型机的制作。它的好处在于我们有了大量的技术积累,甚至可以基于我们的研究成果去推动标准发展,在5G标准发布后可以快速地提供可商用的产品,掀起5G建设的浪潮。”张建国坦言。

  5G时代,流量的增长是毋庸置疑的。《爱立信移动市场报告》预测到2022年,亚太区智能手机用户的月均流量将接近10GB。那么资费会怎样呢?“我们可以回顾一下从2G到3G,从3G到4G,我们都目睹了网速的飞速提升、流量的翻倍增长,但整体资费呈下降趋势。所以,我们还是可以寄希望于一个美好的5G时代。”张萌说。
