美国东北大学动态|建立庞大数据中心,构建和测试下一代无线技术!-新东方前途出国

　　The National Science Foundation and the Defense Advanced Research Projects Agency have selected Northeastern University to run a massive data center that will enable researchers around the country to build and test the next generation of wireless technology and find new ways to use artificial intelligence to shape the smart devices of the future. 

　　美国国家科学基金会和国防高级研究计划署选择了东北大学，建立了一个庞大的数据中心，使全国各地的研究人员能够构建和测试下一代无线技术，并找到利用人工智能来塑造未来智能设备的新途径。

 

　　The testbed, named Colosseum after the iconic Roman amphitheater, is the world’s most powerful emulator of wireless systems. It can process more information in a single second than is estimated to be held in the entire print collection of the Library of Congress.

　　这个以罗马圆形剧场命名的试验台是世界上最强大的无线系统仿真器。它可以在一秒钟内处理更多的信息，而不是在国会图书馆的整个打印集合中进行的估计。

 

　　Colosseum is capable of creating virtual environments that have hundreds of wireless signals hurtling through them, which will enable researchers to understand how these signals interact, develop artificial intelligence algorithms that allow more devices to share the wireless space, and design ways to protect the system from attackers. 

　　罗马斗兽场能够创造出数百个无线信号通过它们的虚拟环境，这将使研究人员能够理解这些信号是如何相互作用的，开发出允许更多设备共享无线空间的人工智能算法，并设计保护系统免受攻击者的方法。

 

　　Here’s how the future of wireless technology might look 

　　以下是无线技术的未来

 

　　“With Colosseum, you can see how 250 intelligent radios interact with one another across a square kilometer,” says Tommaso Melodia, the William Lincoln Smith Chair Professor of Electrical and Computer Engineering at Northeastern. “You can very simply emulate all of these very complex scenarios. This will help us design and build the wireless systems of tomorrow.” 

　　“在竞技场上，你可以看到250个智能无线电是如何在一个平方公里的范围内相互作用的，”东北部的电气和计算机工程系的William Lincoln Smith教授Tommaso Melodia说。“你可以非常简单地模拟所有这些非常复杂的场景。这将有助于我们设计和构建未来的无线系统。”

 

　　Colosseum will move from the Applied Physics Lab at Johns Hopkins University to Northeastern’s Innovation Campus in November, where it will join the Platforms for Advanced Wireless Research program, which is co-led by Northeastern and US Ignite. The program, which is supported by the National Science Foundation, provides researchers with facilities to experimentally evaluate wireless networked systems in real-life testing scenarios. The addition of Colosseum will allow researchers to virtually test their ideas before taking them to one of the program’s real-world testing sites. 

　　斗兽场将于11月从约翰霍普金斯大学的应用物理实验室迁至东北部的创新园区，加入东北部和美国Ignite共同领导的先进无线研究计划平台。该项目得到了国家科学基金会的支持，为研究人员提供了在现实测试场景中实验评估无线网络系统的设施。竞技场的加入将使研究人员在将他们的想法带到项目的一个真实世界的测试站点之前，能够对他们的想法进行虚拟测试。

 

　　Colosseum will become part of Northeastern’s Institute for the Wireless Internet of Things, under the leadership of Melodia, associate professors Kaushik Chowdhury and Stefano Basagni of the College of Engineering, and Abhimanyu Gosain, who is the technical director of the Platforms for Advanced Wireless Research program. 

　　斗兽场将成为东北部无线物联网研究所的一部分，由Melodia、工程学院的Kaushik Chowdhury和Stefano Basagni副教授以及高级无线研究项目平台技术总监Abhimanyu Gosain领导。

 

　　Colosseum, which takes up almost 1,000 square feet of space, can emulate, in real time, up to 256 wireless devices, interacting across 65,000 channels. This processing power can be used to create virtual worlds, as though the devices were operating in, say, an open field, a shopping mall, or a desert, and run simulations to see how wireless signals bounce off buildings or interfere with one another as they move through space. 

　　竞技场占据了将近1000平方英尺的空间，可以实时地模拟多达256个无线设备，在65000个通道上相互作用。这种处理能力可以用来创造虚拟世界，就像这些设备在一个露天场地、一个购物中心或一个沙漠中运行一样，并且运行模拟来观察无线信号是如何从建筑物中反弹或者在穿过空间时相互干扰的。

 

　　The spectrum of useable wireless frequencies isn’t infinite. It’s getting more crowded every day, as a growing number of devices, such as tablets, thermostats, and even refrigerators, rely on wireless communication. Signals on the same frequency can disrupt and interfere with one another, if they’re in the same area, and it is becoming increasingly difficult to keep this from happening. 

　　可用无线频率的频谱不是无限的。由于越来越多的设备，如平板电脑、恒温器，甚至冰箱，都依赖于无线通信，每天都变得越来越拥挤。同一频率上的信号如果彼此处于同一区域，就会相互干扰和干扰，并且越来越难以阻止这种情况发生。

 

　　Northeastern’s expertise in radio frequency research, combined with the processing power of Colosseum, perfectly position the university to solve this and other challenges facing the future of wireless technologies, says David Luzzi, senior vice provost for research and vice president of Northeastern’s Innovation Campus in Burlington, Massachusetts. 

　　东北大学在无线电频率研究方面的专长，结合CuloSeMe的处理能力，完美地定位了大学，以解决无线技术未来面临的这一挑战和其他挑战，东北创新学院的研究和副总裁、高级副教务长David Luzzi说。

 

　　Northeastern already houses a state-of-the-art drone-testing facility, where researchers use an array of antennas and radios to create complicated environments full of wireless signals that could be used to disrupt drones. 

　　东北部已经拥有一个最先进的无人驾驶飞机测试设施，研究人员使用一系列天线和无线电来创造复杂的环境，这些无线信号可以用来破坏无人机。

 

　　“Bringing Colosseum to Northeastern is a testament to the university’s leadership in radio frequency research,” Luzzi says. “This unique-in-the-world combination of facilities will be an asset for radio frequency research by Northeastern, its research and development partners, and users from around the nation. We expect major advances that originate from the work done with these facilities to advance U.S. leadership in radio frequency telecommunications.” 

　　“把斗兽场带到东北部，证明了该大学在无线电频率研究方面的领导地位，”Luzzi 说。“这一全球独一无二的设施组合将成为东北航空公司、其研发合作伙伴和全国用户进行射频研究的一项资产。我们预计，与这些设施的合作将带来重大进展，推动美国在射频通信领域的领导地位。”

 

　　Colosseum, which cost $20 million to build, was originally designed by the Defense Advanced Research Projects Agency for a competition in which teams of researchers around the country used artificial intelligence to collaboratively decide how to share the wireless spectrum in specific scenarios. 

　　建造成本为2000万美元的竞技场，最初是由美国国防高级研究计划署（defense advanced research projects agency）设计的，目的是参加一个竞赛，在这个竞赛中，美国各地的研究人员团队利用人工智能协同决定如何在特定场景中共享无线频谱。

 

　　Northeastern submitted a proposal to the Defense Advanced Research Projects Agency and the National Science Foundation to take over the management of Colosseum once the competition ends, and received $5 million in funding from the National Science Foundation to support the effort. 

　　东北大学向美国国防部高级研究计划局和国家科学基金会提交了一份提案，建议在竞技场比赛结束后接管竞技场的管理工作，并从国家科学基金会获得了500万美元的资助。

 

　　“Northeastern University ably demonstrated the technical expertise and organizational support required to manage the transition of the Colosseum from DARPA to NSF, and was selected through a highly competitive review process meeting the expectations from both DARPA and NSF,” says Monica Ghosh, who is managing the project for the National Science Foundation. 

　　“东北大学很好地展示了管理斗兽场从DARPA过渡到NSF所需的技术专长和组织支持，并通过一个极具竞争力的评审过程来选择，以满足DARPA和NSF的期望，”Monica Ghosh说。他正在为国家科学基金会管理这个项目。

 

　　At Northeastern, Colosseum’s capabilities will be expanded to allow researchers to build their own scenarios, enabling them to study and design systems capable of handling the numerous challenges arising in an increasingly wireless world. 

　　在东北部，斗兽场的功能将得到扩展，使研究人员能够构建自己的场景，使他们能够研究和设计能够应对日益无线化的世界中出现的众多挑战的系统。

 

　　“Colosseum was designed to challenge the world to tackle the hardest problems in spectrum-sharing by embracing the intersection of wireless communications and artificial intelligence,” says Paul Tilghman, the program manager at the Defense Advanced Research Projects Agency who spearheaded the competition. “I’m excited that Colosseum will continue to allow this type of impactful research for years to come.” 

　　“CuloSeMe的设计是通过挑战无线通信和人工智能的交叉点来挑战世界来解决频谱共享中最困难的问题，”负责这项竞争的国防高级研究计划署的项目经理Paul Tilghman说。“我很高兴罗马竞技场能在未来几年里继续进行这种有影响力的研究。”

 

　　Colosseum will be made available to the wider community of academic, industry, and government researchers in April 2020. 

　　斗兽场将于2020年4月向更广泛的学术界、工业界和政府研究人员开放。

 

　　“We’re going to evolve it over the years, based on the demand from the research community,” Melodia says. “This is a game changer, in terms of the future of how we design complex wireless systems powered by artificial intelligence that interacts with the physical environment.” 

　　“我们将根据研究群体的需求，在未来几年内对其进行改进，”Melodia说。“就我们如何设计由人工智能提供动力、与物理环境交互的复杂无线系统而言，这是一个改变游戏规则的因素。”
