太赫兹技术最令人兴奋的未来应用之一是在无线通信领域。随着采用毫米波无线链路标准的5G系统接近商业推广，很明显，即使是这种新的基础设施也不足以跟上快速增长的全球带宽需求。一个吸引后续几代无线技术越来越多关注的有利解决方案是使用高于100 GHz的更高频率。实现这样的链接将需要在硬件、算法和架构方面取得重大进展。尽管许多研究小组正在探索这个具有挑战性的问题的各个方面，但许多基本问题仍未得到解决。在这里，我们提出了一个实验的努力，在室内和室外环境中的太赫兹无线链路的特点。我们在100，200，300和400 GHz的测量报告，使用1 Gbit/s的数据速率的链接。我们演示了视线和非视线（镜面反射）的内部建筑墙壁的链接。这项工作是确定在不同情况和环境下使用太赫兹载波进行数据传输的可行性的第一步。(c)2018年作者。
One of the most exciting future applications of terahertz technology is in the area of wireless communications. As 5G systems incorporating a standard for millimeter-wave wireless links approach commercial roll-out, it is becoming clear that even this new infrastructure will not be sufficient to keep pace with the rapidly increasing global demand for bandwidth. One favorable solution that is attracting increasing attention for subsequent generations of wireless technology is to use higher frequencies, above 100 GHz. The implementation of such links will require significant advances in hardware, algorithms, and architecture. Although numerous research groups are exploring aspects of this challenging problem, many basic questions remain unaddressed. Here, we present an experimental effort to characterize THz wireless links in both indoor and outdoor environments. We report measurements at 100, 200, 300, and 400 GHz, using a link with a data rate of 1 Gbit/s. We demonstrate both line-of-sight and non-line-of-sight (specular reflection) links off of interior building walls. This work represents a first step to establish the feasibility of using THz carrier waves for data transmission in diverse situations and environments. (c) 2018 Author(s).
