Theodore Rappaport：鉴于不断革新的半导体技术展现出了超凡的新计算和通信能力，无线网速的只能在竞争中变得越来越快。根据摩尔定律，集成电路的性能大约每18个月就会翻一番。在NYU WIRELESS， 6G的研究已经开始。我们最近写了一篇愿景文章，展示了10到15年内无线技术如何能够远程传输人脑的计算能力，这意味着人类速度的计算可以在低功耗远程平台实现，这可能应用于未来的机器人和自动驾驶汽车中。
Theodore Rappaport：我认为5G只是蜂窝通信的新一代技术，将在未来8到10年内发展和成熟，带来应用和产品的革新和生产力的提升，就像之前的4代手机一样。而5G独特新颖、称得上业界飞跃的一点，在于5G首次开放了毫米波频谱。这是全新的无线方案，其中微小的定向可操纵天线将首次用于移动设备的超快速传输；带宽加宽，使无线可以开始取代农村地区老化的铜制设备。NYU WIRELESS在引领全球考虑5G的毫米波方面发挥了先锋作用，我认为6G和7G将继承并优化这些想法，并在毫米波和亚太赫兹频谱方面取得新进展。
JRJ: The 5G standard competition is something the world is talking about over the past years, in your opinion, is there any company or country leading the race?
Theodore Rappaport：There are many global carriers in the USA, Asia and Europe who are ramping up on the learning curve of 5G installation and services, and many device companies who are investing heavily and leading the way. I believe that Qualcomm is a global leader in 5G technology, and that Samsung and Huawei are also very strong in 5G. I believe that equipment suppliers such as Nokia, Ericsson, Sony and Oppo are developing exciting products and new applications for 5G. Chip companies like UMC are making the new chips that will go in 5G phones and base stations.
JRJ：5G is widely consider to be the next big thing for the world productivity and creation, what industries will be changed and what industries will be created?
Theodore Rappaport：Since 5G will provide fiber optic speeds to the pocket of future cellphone users, we will see amazing new applications that cannot even be envisioned yet. We will see health care, industrial automation, travel and entertainment, vehicular technology, and social media adapt to these new capabilities. The portable cellphone will become more integral in how all of our information is consumed and stored, and the cloud will continue to evolve as more and more vital to our world. More and more, wireless devices such as cellphones or tablets will replace pen and paper and televisions and personal computers in our daily lives.
JRJ：Most people have one thing in mind when talking about 5G — fast internet speed, and they will be right. However, why speed matters? is 5G enough for all the future internet?or maybe the internet speed raise will become a never-ending game?
Theodore Rappaport：There will always be a race for more speed, faster and wider wireless pipes, as the continuous evolution of semiconductor technology enables amazing new computing and communications capabilities – doubling approximately every 18 months per Moore’s law. At NYU WIRELESS, we are already working on 6G, and recently wrote a vision paper that shows how wireless in 10-15 years may be able to transmit the computing power of the human brain remotely, meaning that human-speed computations could be done in low power remote platforms, perhaps for robots and autonomous vehicles of the future (Link: https://ieeexplore.ieee.org/document/8732419)
JRJ： What is your personal view on 5G, is this the real thing that shape the future like it’s called out to be?
Theodore Rappaport：I think 5G is just another technology generation of cellular communications, will evolve and mature within the coming 8-10 years, and will enable new applications and products and more productivity enhancement, just as the previous 4 generations of cellphones have done.
What is especially novel, and a leap for the industry, is that 5G is the first time we are opening up the millimeter wave spectrum, which is the start of completely new approaches to wireless where tiny directional steerable antennas will be used to provide super-fast transmissions to mobile devices for the first time, and where bandwidths become wide enough that wireless can begin to replace aging copper plant in rural areas. NYU WIRELESS played a pioneering role in leading the world to consider millimeter wave for 5G, and I think 6G and 7G will embrace and improve on these ideas and go higher in the millimeter wave and sub-Terahertz spectrum, and we will see vast productivity enhancements and new products and services evolve that are so much more data intensive than we could have ever imagined, simply due to the wider channel bandwidths, faster speeds, and new network architectures that will enable such massive amount of content and data to be delivered to individuals over the cellphone airways. The cellphone in 10 years from now may be used for see-in-the-dark imaging, personal health monitoring, air quality monitoring, and much more.
