“…An RF‐over‐fiber (RFoF) (introduced in (Abbasi, Hariharan, Nair, Almaiman, et al., 2020 )) system allows the system to operate over longer measurement distances (up to 100 m) in comparison to typical systems (less than 10 m). For further details of the setup, please see (Abbasi et al., 2019 ; Abbasi, Ponce, Kondaveti, Shaikbepari, et al., 2021 ). While the complete configuration of the sounder varies over the various experiments due the requirements of each particular measurement, some of the common parameters are summarized in Table 1 .…”

“…Both horn antennas face entrance A. The modification applied in this scenario was to increase the reflectivity of the pillars by wrapping them with an aluminum foil centered at 1.65 m height (as explained in (Abbasi, Gomez‐Ponce, Shaikbepari, et al., 2021 )). The specific configuration for this scenario is shown in Table 2 .…”

“…Statistical analysis for a desktop THz channel at 300 GHz is discussed in (Kim & Zajić, 2015 ). Recent papers by our group cover channel measurements and statistical analysis for urban outdoor device‐to‐device (Abbasi et al., 2019 ; Abbasi, Hariharan, Nair, & Molisch, 2020 ; Abbasi, Ponce, Kondaveti, Shaikbepari, et al., 2021 ) and microcell scenarios (Abbasi, Ponce, Kondaveti, Kumar, et al., 2021 ) at 140 GHz. Also, recently the authors of (Xing et al., 2021 ; Xing & Rappaport, 2021 ) have performed and analyzed channel measurements above 140 GHz.…”

“…For the current paper, we choose scenarios and objects that represent common indoor and outdoor communication applications for the THz band. We first revisit a set of outdoor measurements (previously described in our conference paper (Abbasi, Gomez‐Ponce, et al., 2021 )) and discuss the results and the scenario in more detail. We then describe several indoor measurements where we assess the impact of energy‐saving (low‐e) glass versus common glass, open windows versus blinds, and the impact of using high tint glass inside buildings.…”

THz band communication has the potential to meet the high data rate demands of many current and future applications. However, before these networks are realized, extensive channel measurements are needed in order to characterize the wireless channel at these frequencies, in order to inform system design and deployment. In the current paper, we present a set of double‐directional channel measurements that are conducted in several relevant indoor and outdoor scenarios. Our aim is to see the effect of common building materials that might be particularly reflective or absorptive (such as energy‐saving glass, window blinds, or metallic reflectors), and how their presence changes the channel characteristics. Among other effects we find that ‐ depending on the considered dynamic range ‐ presence/absence of these materials can increase the required equalizer length by an order of magnitude.

“…Among other techniques including EM wave theory and full-wave simulation, channel measurement is essential to characterize the spectrum features and develop channel models. Recently, with the progressive narrowing of the THz technology gap, experimental measurement campaigns in the lower THz band have been conducted [118]- [121]. Such experimental measurements play a dual role: on the one hand, they can be used to validate the analytical physics-driven models.…”

TeraHertz (THz) band communications are envisioned as a key technology for 6G and Beyond. As a fundamental wireless infrastructure, THz communication can boost abundant promising applications. In 2014, our team published two comprehensive roadmaps for the development and progress of THz communication networks [1], [2], which helped the research community to start research on this subject afterwards. In particular, this topic became very important and appealing to the research community due to 6G wireless systems design and development in recent years. Many papers are getting published covering different aspects of wireless systems using the THz band. With this paper, our aim is looking back to the last decade and revisiting the old problems and pointing out what has been achieved in the research community so far. Furthermore, in this paper still to be investigated new research challenges for the THz band communication systems are presented by covering diverse subtopics such as from perspectives of devices, channel behavior, communication and networking problems, physical testbeds and demonstration systems. The key aspects presented in this paper will enable THz communications as a pillar of 6G and Beyond wireless systems in the next decade.
