对于无线技术的速度和功能,需求量已达天文数字,而供应量却明显不足。新冠疫情引发的健康危机或许已经改变了这一点。
2 5G蜂窝技术开始成形,据称,其提供的连接架构可以在全球范围内提供无缝化数字体验。这种连接架构仍存在一些细微缺陷,在2020年,面对新冠疫情,数亿人被迫远程工作和社交,令这一点暴露无遗。
3期待已久的5G体验一旦成真,势必令人眼花缭乱:智能工厂、远程医疗和增强现实都会成为常态。无论处于静态还是动态,用户都能随处享用高速连接。戴尔科技公司产品和运营总裁兼首席技术官约翰·勒泽称:“从教育到医疗保健,从交通到工作,当你不得不重塑所有这些体验时,会突然意识到自己欠缺的是什么。”他指出,当前所欠缺的,正是能够实现这一切的IT基础设施。
4目前,市场上大多数服务只提供移动宽带。这的确是个很好的开端,但也只是走向未来的一小步。5G具有三大特性,即增强移动宽带、低时延高可靠通信和机器间通信,因而只需极少人工参与即可为大量设备提供连接。只有待供应商在全球范围内实现5c的这些特性之后,人们才能真正感受到这三方面的效力,这至少还要等上几年。
5这就是说,尽管5G需求量激增,但实际应用并不如意。诚然,分散部署在美国许多城市的5G网络可以为手机用户提供服务。还有一些窄域部署的5c网络被用于解决特殊任务,比如供应链问题和地理围栏技术,后者可以使自动驾驶汽车集中在特定的地理区域。不过,勒泽指出,距离5G覆盖全球,“可能还需要三年的时间”。
6那么,5G连接架构完善之后会是什么样子?恰似一件宽松的衣服。
7如今,5G技术可以实现云编排(即,利用软件定义的原则,管理公有云和私有云基础设施上的工作负荷之间的互联和交互),故而,可以改变5G网络的行为,适配特定用途的特定应用。勒泽举例对远程医疗加以形象说明:在前往医院途中,疑似中风患者可以接受诊断及初步治疗。这可以通过对患者数据的连续收集和流式传输来实现。勒泽指出:“为了做到这一点,必须具备一系列条件。代码必须精益求精,这样才能实时运行。必须执行一个网络切片来保证带宽,并为远程医疗提供优先服务。”如果手动分配,重新配置网络可能需要三个小时或更久。
8移动诊疗的实现,离不开蜂窝网络的优势。这对于创新至关重要,对于普通5G用户也是如此。高通公司工程技术高级副总裁马德嘉指出:“这意味着,当你在城中走动,如果网速始终能达到每秒100—__200兆比特,那么峰值速率可能达到每秒5—10吉比特。但如果保证网速达到每秒100—200兆比特,平均而言,可能是每秒1吉比特,那么你个人设备的最终使用方式会由此改变,为新型设备奠定基础。”
9随着5G和Wi-Fi的融合,无缝覆盖还有其他用场。自2019年无线网络技术最新标准Wi-Fi 6推出以来,这一趋势更加明晰。思科企业网络事业部副总裁兼首席技术官约翰·阿波斯托洛普洛斯举了一个例子:一位企业高管在家里开始典型的一天,打开连接Wi-Fi网络的移动设备,查看电子邮件或浏览新闻提要。开车上班途中,设备切换到蜂窝5C;工作中切回Wi-Fi;午餐时又是5C。
10要实现5G的其他功能,也许需要更长时间。5G连接架构若要达到无缝化,就要适应越来越高速的数据、超低时延和數以亿计连接到物联网的低能耗设备。这些总归会实现,不过困难重重。正如戈德史密斯所言:“当下网络环境(包括规划中的5G网络)无法支撑的应用程序,需要异构程度大得多的网络才能运行。但我觉得,当前5G这一代,我们还没搞定其中任何一项。”

Demand for the wireless technology’s speed and power has reached astronomic1 heights—while supply remains conspicuously2 low. The coronavirus health crisis may have changed that.
5G cellular technology, which has been promised to provide a connective fabric that will cover the globe in a seamless3 digital experience, is starting to take shape. But the coronavirus pandemic of 2020 that has forced hundreds of millions of people to work and socialize remotely has made it clear that the connective fabric is still missing a few stitches.
Once implemented, the long-anticipated 5G experience will be dazzling: smart factories, telemedicine, and augmented reality will be commonplace. Users will have ubiquitous, high-speed connectivity everywhere, whether moving or at rest. “When you have to re-create all of these experiences—from education to health care to transportation to work—you suddenly realize what you’re missing,” said John Roese, president and CTO of products and operations at Dell Technologies. What’s missing, he indicated, is the IT infrastructure that makes it all possible. Most services on the market today deliver only mobile broadband. It’s a great start, for sure, but only a whisper of what’s ahead. The true impact of three key 5G features—enhanced mobile broadband, lightning-fast, ultra-reliable communications, and machine-to-machine communication, which provides connections to large numbers of devices with minimal human involvement—is unlikely to be felt until vendors start to bake them into global deployments, a few years ahead at least.
That means while demand for 5G is surging, access to it lags. Yes, mobile phone users can now tap into scattered deployments of 5G in many US cities. And there are narrow deployments of 5G being used to solve specialized tasks, such as supply chain problems and geofencing4, which can be used to keep autonomous vehicles corralled in specific geographic areas. But “we’re probably three years away” from worldwide adoption of 5G, said Roese.
So, what will this 5G connective fabric look like when it’s all stitched up? A loose-fitting garment.
Because 5G technology can now be cloud orchestrated5—that is, use software-defined principles to manage the interconnections and interactions among workloads on public and private cloud infrastructure—the behavior of the 5G network can be changed to accommodate specific applications for specific uses. Roese shared a dramatic example of this by describing a telehealth scenario in which suspected stroke victims could be diagnosed and receive initial treatment while en route to the hospital. This would be accomplished by using the continuous collection and streaming of patient data. “In order to do that, a whole bunch of conditions had to be true,” said Roese. “You had to push the code out to an edge, so it can operate in real time. You had to execute a network slice to guarantee the bandwidth and give this a priority service.” If such allocation were done manually, it might take three hours or more to reconfigure the network.
One thing that makes mobile triage possible is strength at the edge of the cellular network. That is also crucial for innovation—as well as for the average 5G user. “What that means is you’re walking around in a city and if you constantly get 100-to-200 megabits per second, the peak rates might be five-to-10 gigabits per second,” said Durga Malladi, senior vice president of engineering at Qualcomm. “But if you’re guaranteed 100-to-200 megabits per second, and on an average, maybe a gigabit per second, that transforms the way that you end up using your devices and enables new kinds of devices.” There are other opportunities for seamless coverage emerging as 5G and Wi-Fi converge. This is particularly true since the 2019 introduction of Wi-Fi 6, the latest standard for the wireless networking technology. Consider this example given by John Apostolopoulos, vice president and CTO in Cisco’s Enterprise Networking Business: A business executive starts a typical day at home checking email or news headlines on a mobile device, which connects to a Wi-Fi network. As he drives to work, the device switches to cellular 5G. At work, it goes back to Wi-Fi, and at lunch, 5G again.
Other promises of 5G may take longer to fulfill. For the connective 5G fabric to be seamless, it will need to accommodate increasingly high-speed data, very low latency, and the hundreds of millions of low-energy devices that connect to the internet of things. That will happen, but it won’t be easy. “We need a much more heterogeneous network that can support applications that today’s—even the design of 5G network—isn’t able to do,” said Goldsmith. “I would argue that we haven’t got any of those nailed in the current generation of 5G.”
