This paper presents measurements and statistical characterization to compare three potential bands of the low-THz channel, namely, the 300 to 319 GHz, 340 to 359 GHz and 380 to 399 GHz bands. From the large set of measurements performed in line-of-sight (LoS) and non-LoS (NLoS) environments, parameters for path loss model with shadowing are evaluated. Our results show that the path loss exponents for the band around 310 GHz, 350 GHz, and 390 GHz is 2.07, 1.90 and 1.96, respectively. The impacts of different materials acting as surfaces in LoS channels and reflectors in NLoS environments are also examined. Additionally, the statistical analysis due to temporal, spatial and multipath propagation is performed to determine the best fit distributions. Finally, we look at some networking scenarios in THz Band communication to derive the expressions for the number of connections a user can make based on antenna characteristics, data rate requirements and antenna mobility as well as network density. Our results suggest fundamental parameters that can be used in future THz Band analysis with applications in both macro and micro scale Internet of Things (IoT).

本文介绍了测量和统计特性，以比较低THz信道的三个潜在频带，即300至319 GHz，340至359 GHz和380至399 GHz频带。通过在视距（LoS）和非LoS（NLoS）环境中执行的大量测量，可以评估带有阴影的路径损耗模型的参数。我们的结果表明，在310 GHz，350 GHz和390 GHz附近的频带的路径损耗指数分别为2.07、1.90和1.96。还研究了在LoS通道中用作LoS通道表面和反射器的表面的不同材料的影响。另外，执行由于时间，空间和多径传播引起的统计分析，以确定最佳拟合分布。最后，我们研究了THz频段通信中的一些网络场景，以根据天线特性，数据速率要求和天线移动性以及网络密度得出用户可以建立的连接数的表达式。我们的结果表明，可以在未来的太赫兹频段分析中使用的基本参数，可同时应用于宏观和微观的物联网（IoT）。
