“…In FANETS, the THz band achieves high capacity at greater flexibility compared to FSO, which has stringent pointing and acquisition requirements. Nevertheless, drones operating at the THz band would require millimeter levels of positioning accuracy [14], as opposed to less than a centimeter for a drone operating at 30 GHz.…”

Terahertz (THz)-band communications are celebrated as a key enabling technology for next-generation wireless systems that promises to integrate a wide range of datademanding and delay-sensitive applications. Following recent advancements in optical, electronic, and plasmonic transceiver design, integrated, adaptive, and efficient THz systems are no longer far-fetched. In this paper, we present a progressive vision of how the traditional "THz gap" will transform into a "THz rush" over the next few years. We posit that the breakthrough that the THz band will introduce will not be solely driven by achievable high data rates, but more profoundly by the interaction between THz sensing, imaging, and localization applications. We first detail the peculiarities of each of these applications at the THz band. Then, we illustrate how their coalescence results in enhanced environment-aware system performance in beyond-5G use cases. We further discuss the implementation aspects of this merging of applications in the context of shared and dedicated resource allocation, highlighting the role of machine learning.

“…It is noteworthy that the most significant attribute of THz communications exists in its capability to facilitate mobile communications at both the access level and the device level in D2D and drone-to-drone communications [27]. There are handful papers deploying UAV communication over the THz channel [28]- [30]. The authors in [28] analyzed the orientation and position estimation capabilities of the THz multiple input multiple output (MIMO)-orthogonal frequency division multiplexing (OFDM) link between two UAVs based on both the position and the orientation error bound.…”

The huge available bandwidth in Terahertz (THz) frequency band is recently contemplated to achieve high data rate wireless communications. Consequently, THz communications are attractive candidates to fulfill the continuous ever-increasing requirements of future wireless networks. Numerous beyond 5G applications are highly considered for those systems such as high capacity backhaul, enhanced hotspot booths as well as short-range device-to-device (D2D) communications. Wireless communications systems that deploy unmanned aerial vehicles (UAVs) promise to achieve cost-effective wireless connectivity for devices without any need to pay for infrastructure coverage. When compared to terrestrial communications, wireless systems with UAVs are generally faster and more flexible to deploy or reconfigure. In addition, systems deploying UAVs are likely to have much better communication channels due to their high mobility capabilities. Accordingly, the presence of short-range line-of-sight (LOS) links prevail. In this paper, we consider a single-cell cellular network with a UAV deployed as a decode-and-forward (DF) relay in the full-duplex (FD) mode in order to assist a base station (BS) and extend its coverage over THz channel. A joint power allocation and trajectory optimization scheme that minimizes the outage probability of the link between the BS and a mobile device (MD) is derived in the presence of the interference of the D2D devices that share the same THz frequency band. Furthermore, the optimum powers of the MD and the UAV that maximize the achievable rate at the BS are obtained. The performance of the proposed schemes is compared with the fixed power allocation schemes which distribute the power equally among users. Numerical results show that the outage probability and the achievable rate at the BS using the proposed schemes are remarkably superior compared to the fixed power allocation schemes.

“…In FANETS, the THz band not only achieves high capacity but is also more flexible for high mobility, unlike FSO that has stringent pointing and acquisition requirements. Moreover, the accuracy of the drones' location heavily depends on the frequency band used, where the localization error needs to be within fractions of the wavelength [14]. For instance, a drone operating at 30 GHz would require a localization accuracy of less than a centimeter.…”

Terahertz (THz)-band communications are celebrated as a key enabling technology for next-generation wireless systems that promise to integrate a wide range of data-demanding and delay-sensitive applications. Following recent advancements in optical, electronic and plasmonic transceiver design, integrated, adaptive and efficient THz systems are no longer farfetched. In this paper, we present a progressive vision on how the traditional THz gap will transform into a THz rush over the next few years. We opine that the breakthrough that the THzband will introduce is not solely driven by the achievable high data rates, but more profoundly by the interaction between THz sensing, imaging, and localization applications. We first detail the peculiarities of each of these applications at the THz band. Then, we illustrate how their coalescence results in enhanced environment-aware system performance in beyond-5G use cases. We further discuss the implementation aspects of this merging of applications in the context of shared and dedicated resource allocation, and we raise some health and privacy concerns.
