“…Table IV illustrates the comparison of the path loss model to the existing 300 GHz channel models. The fitted ABG model is found to be closed to that in [15] and the offset P L(d 0 ) in this study is seen to be 3.2 dB higher than that in [32]. The exponent of the fitted CI model is 0.4 higher than that in [33].…”

“…In the state-of-the-art, there are only a few literature reporting directional/double-directional channel models at 300 GHz frequency bands [15], [32], [33]. Table IV illustrates the comparison of the path loss model to the existing 300 GHz channel models.…”

“…This has led to a plethora of investigations of the impact of common building materials using TDS-based sounders [49]- [51], [91] and VNA-based sounders [48]. THz bands are known to be inherently directive and hence efforts have been invested to study the attributes of directional propagation in several studies [61], [72], [73], [76], [110], [116], [121], [135], [136]. However, such directional campaigns suffer from extensive time requirements which often limit the number of measurement points or time and frequency resolution.…”

“…Furthermore, the band is expected to support profound applications in short distances preferably in the LoS environment. Such a requirement motivated investigation of the channel across several THz frequency bands in common indoor spaces such as office rooms [61], [65], [66], [72], [96], [110], [116], [118], [120]- [123], [127], [137], [138], desktops [36], [59], [110], [113]- [115], [117]- [119], [124]- [126], conference rooms [33], [76], [116], [120], [122], data centers [74], [129]- [131], and in some not-so-common spaces like factory buildings [73], shopping malls [109], [112], and airports check-in halls [112], lecture rooms [128], to name a few using different channel sounders. Some dynamic channel characterization for UMi [80]- [84] and different railway communication channels [88]- [90], [139] have also been investigated using a TDC-based sounder and in an urban environment using a VNA-based sounder [55], [134]- [136].…”

“…A similar inference as in [109] was drawn where there was similarity in dominant MPCs but the lower frequency band seemed to present weaker MPCs. In [110], measurement campaigns were conducted for three different frequency bands: 125 − 155, 235 − 265, 270 − 300 GHz in two different laboratories of dimensions 12.9 × 7.15 × 4 m 3 and 9.7 × 4.73 × 4 m 3 respectively for MPC detection, along with clustering of the detected MPCs. In addition, path loss, and delay spread models were reported in this work.…”

As the world warms up to the idea of millimeter wave (mmWave) communication and fifth generation (5G) mobile networks, realization slowly dawns that the data rate, latency, throughput, and other performance metrics that are used to assess a new wireless communication technology will not be enough to support the demands of envisioned futuristic applications. Thus there is an eagerness to further climb up the frequency ladder to use the large swathes of available spectrum in the 0.1 − 10 THz band which is expected to act as the key technology enabler to fulfill the requirements of the sixth generation (6G) wireless communication and possibly even beyond. Channel measurement and modeling are crucial to the design and deployment of future wireless communication systems and researchers across the world are putting their best foot forward to accelerate the process. The present article presents comprehensive assimilation of research efforts in the context of THz channel sounding. A detailed overview of the current channel sounding techniques is first introduced followed by their relevance to THz band channel measurement. An in-house novel channel sounder developed for THz band measurement is also briefly introduced in this context. The paper next provides elaborate dissemination of various measurement campaigns in the band of interest followed by the modeling techniques that are available in the literature and are being adopted for the THz band. Post the description of different challenges and future research directions in the context of sounding, measurement, and modeling the article is concluded.

For 5G beyond and/or 6G mobile services, a new spectrum at frequencies above 100 GHz has received great attention lately. To characterise the similarities and the differences between frequencies below 100 GHz and above 100 GHz, this paper provides analyses of multi‐frequency propagation characteristics based on wideband measurements at 28, 38, 71, 82, and 159 GHz, with an emphasis on the sub‐THz (i.e. the 159 GHz) propagation characteristics. All the frequency measurements were conducted in the same cubicle office room environment by locating the transmitter and the receiver at the same positions. The measurement results show that the path loss and the shadow fading characteristics do not exhibit significant differences depending on the frequency range from 28 to 159 GHz. However, the delay spread shows a generally decreasing trend as the frequency increases. Additionally, angular domain analyses were conducted with the 159 GHz measurements.
