Over the last decade, short-range communications in the THz (Terahertz) band have been extensively studied as a technology-enabler for dense and ultra-dense wireless networks. The increasing demand for high data rates for wireless communication systems will inevitably lead to the extension of operation frequencies with larger bandwidths. THz range enables bandwidths on the order or hundreds of GHz. Thus, THz Band communication will alleviate the capacity limitations and spectrum scarcity of current wireless systems, and enable new classical networks and novel nanoscale networks applications. The main aim of this paper is to provide design guidelines for close proximity links with transmission capacity beyond 100 Gbit/s. We present the path loss, absorption loss, signal to noise ratio (SNR) and capacity of propagating electromagnetic waves at THz Band in different air medium types. The channel capacity and SNR properties are calculated according to transmit power estimation. In this paper, five air medium types are investigated which are average latitude—summer, high latitude—summer, average latitude—winter, high latitude—winter and tropics.

在过去的十年中，作为密集和超密集无线网络的技术支持者，已广泛研究了THz（Terahertz）波段的短距离通信。对于无线通信系统对高数据速率的日益增长的需求将不可避免地导致具有更大带宽的工作频率的扩展。THz范围可实现大约数百GHz的带宽。因此，太赫兹频带通信将减轻当前无线系统的容量限制和频谱稀缺性，并使新的经典网络和新颖的纳米级网络应用成为可能。本文的主要目的是为传输能力超过100 Gbit / s的近距离链路提供设计指南。我们给出路径损耗，吸收损耗，信号噪声比（SNR）和不同空气介质类型在THz频段传播的电磁波的容量。根据发射功率估计来计算信道容量和SNR属性。本文研究了五种空气介质类型，分别是平均纬度-夏季，高纬度-夏季，平均纬度-冬季，高纬度-冬季和热带。
