5G technology

革命已经happening

随着新的第五代移动网络的推出,观看高清电影或在旅途中与家人享受无延迟的面对面时间将只是一场深刻而持久的技术革命的开始。实时可靠的移动宽带很快将允许无数的互联网连接,为一系列革命性的应用打开大门。所有这些对于AirLiquide在为5G提供基础设施的半导体行业的客户来说都是好消息。

For telecommunications experts, the high level of public and political interest in the 5G technology standard for broadband cellular networks is something of a novelty. After all, rolling out a new mobile network is nothing new: the clue is in the name “5G” – fifth generation. While 2G was barely noticed, 3G was popular with States (who auctioned bandwidth to generate windfalls), and 4G was primarily a topic of discussion for those who work in the technology sector, 5G has become a worldwide news item: geopolitics and trade wars, populism and conspiracy theories – the roll-out of this new generation of networks has garnered more attention than any previous.

因此,我们可以很容易地监督,尽管人们仍在谈论5G将要发生的事情,但事实上,5G已经发生了。2019年开始部署,将于2020年代中期在发达经济体完成部署。到2025年,将覆盖全球约三分之二的人口,5G带来的全面转型将开始成为现实。

5G技术解释器

6,400项专利的筏子弥补了标准分解为三个关键技术。betway旗舰版下载首先,虽然现有的移动网络在0-6 GHz频谱中,5G将看到它们扩展到52.6 GHz。这光谱增强打开更高的频率,使下载和上传速度在低延迟(即没有延迟)下达到每秒数十千兆字节。其次,5G天线将无线电波专门定向在设备上,而不是简单地向各个方向广播。打电话波束成形,该技术增加了信号质量。第三,massive MIMO antennas在一个阵列中提供数百个天线,这意味着它们可以在任何时候为数千个设备提供服务–MIMO代表“多输入、多输出”。

由于增加的频谱允许更快的速度和更低的延迟,波束形成确保了更好的信号质量,并且mimo提供了对更多设备的无中断访问,5G开辟了一系列的可能性,直到现在,这些可能性似乎还是科幻小说。原因是,如果你能保证高速连接而不降低连接,这不仅让智能手机用户更容易观看猫可爱的视频或与他们的祖母玩facetime:它还允许机器相互连接,并让安全关键的过程可以远程控制。

物联网初具规模

这是M2M - 机器到机器的本质 - 和物联网 - 物联网。从2024起开始,5G将提供超低延迟,这意味着连接的延迟将在毫秒中测量。结合与有线宽带连接相当的中断和停机时间,这开辟了使用移动网络的可能性,直到现在,由于安全或可靠性问题,已经排除在外。例如,在制造中,可以连接整个生产线,随着系统的不同部位实时可靠地互相通信,出现了全新的自动化选项。

自动驾驶变得真实

自动驾驶应用程序也是如此,它的标准化速度将远远快于目前看来可能出现的速度。毕竟,自动驾驶汽车已经在工厂和仓库周围行驶,可以排除外界干扰,并且可以保证连通性。一旦5G极大地提高了连接速度,并能够提供真正可靠的跨城市(最终是农村)地区的接入,就没有理由不在各种情况下部署自动驾驶。

远程医学超出了视频咨询

医疗服务数字化也有可能达到一个全新的水平。在最基本的层面上,5G提供宽带互联网意味着,即使是生活在没有高速固定电话连接的偏远地区的患者,也可以进行彻底的视频会诊;医生将能够发送和接收高分辨率图像,并与患者和其他医疗人员共享。然而,让人感到真正革命性的将是远程医疗:例如,外科医生控制机器人远距离执行医疗程序将不再有任何技术障碍。

当然,仍然是某种方式。然而,在您读取的情况下,正在安装这样的基础架构,以便正在安装这样的未来派似乎是这样的场景。因此,虽然电信专业人员可能对5G左右的媒体辩论有所惊讶,但事实上,这可能是真正令人惊讶的是,公众和政治对技术的兴趣甚至更强大。

采访Benjamin Jurcik,首席技术官,世界业务线电子,空气液化

作为电子领域的首席技术官,你要密切关注技术的发展。5G将如何改变日常生活?

在日常级别,有些东西5G不会改变。例如,大多数人不会注意到它们是否在智能手机上使用良好的4G连接或5G。但是,5G将导致可以连接的设备数量的持续扩展,并且连接质量的标记增加。简单地说,如果连接了更多设备,并且连通性的速度和可靠性显着增强,则增加了许多应用。

我们是不是在谈论无人驾驶汽车?

Yes. In the medium-to-long term, expect to see automated driving and a wealth of other smart-city functionalities. We may also see surgeons remote-controlling robots for medical procedures, potentially opening up highly-specialised surgery to many more patients at lower cost and with less travel. These are the kind of things that are safety critical requiring the kind of rapid, reliable connectivity 5G will offer.

Before that, though, virtual and augmented reality will really take off: our semiconductors customers are already working with their customers to develop the chips needed for these kinds of applications. Also, smart factory applications are on the starting blocks: machines communicating with each other at factory level will lead to considerable enhancements in productivity, efficiency, and safety – and will be one of the first widespread 5G applications.

液化空气工厂也会改变吗?

They certainly will! As an industry leader, Air Liquide will be a consumer of 5G technologies throughout all of our business lines and will develop new applications exploiting the enhanced connectivity 5G offers – to improve our supply chain management, for example, or to increase safety and reliability.

The most tangible effect for Air Liquide’s activity, however, will be the increase in demand from our customers in the semiconductor industry. All semiconductor market segments (logic, analog, memory, and discrete) will be positively impacted by 5G deployment, and this will boost demand for all of the materials we supply to the semiconductor industry: Carrier Gas, Specialty Materials, Advanced Materials; there will also be strong demand for Equipment & Installations and services. This, of course, will come from a sector which is already booming – semiconductors grew right through the COVID-19 pandemic, for instance – and which will, with 5G deployment, receive additional growth impulses.
