5G技术是一个广泛的概念，它描述了在不久的将来通信技术的颠覆性发展，网络数据速率和容量大幅增加，以支持各种创新服务。毫米波可用的新频谱的开发是5G的关键推动因素。毫米波有望彻底改变室内无线连接，以非常高的数据速率提供非常大的容量。众所周知，毫米波无线电链路受到人体的强烈影响，并且这个问题在室内环境中非常相关。有几种模型可用于射线跟踪调查和视线阻塞，而统计模型，使易于处理的分析研究和模拟的毫米波无线系统，占人们在链路的附近，仍然缺乏。在本文中，测量60 GHz的信道脉冲响应的静态，但“进化”的办公室的情况下，涉及一个，两个和三个人。回归拟合的实验响应，以获得准确的表征人为引起的阴影事件在接近和阻塞的情况。可处理的统计模型提供了不同的场景和八个载波频率跨越频带从54到59 GHz和从61到66 GHz。
5G technology is a broad concept that describes the envisaged disruptive evolution of communication technology in the near future, with a dramatic increase in the network data-rate and capacity to support a variety of innovative services. The exploitation of the new spectrum available at mmWaves represents a key enabler for 5G. mmWaves are expected to revolutionize the indoor wireless connectivity providing a very large capacity at very high data rates. It is well known that mmWaves radio links are strongly influenced by human bodies and this issue is very relevant in indoor environments. Several models are available for ray-tracing investigations and line-of-sight blockage, whereas statistical models enabling tractable analytical studies and simulations of mmWaves wireless systems, accounting for people in the link's proximity, are still lacking. In this paper, measurements of 60 GHz channel impulse responses in static but “evolutionary” office scenarios that involve one, two and three individuals are presented. Regression fits are applied to the experimental responses to obtain an accurate characterization of human-induced shadowing events in both proximity and blockage situations. Tractable statistical models are provided for different scenarios and for eight carrier frequencies spanning the bands from 54 to 59 GHz and from 61 to 66 GHz.
