“…In the past years, various CBCS systems have become available [25], [26], [27], [28] allowing either dynamic measurements or reducing the measurement time in static environments significantly. CBCS have been widely used for measurements in various environments such as outdoor environments [27], office environments [26], industrial environments [29], data centers [30], trains [31], automotive [32], and aircrafts [33]. Recently, CBCS have also been used for channel characterisation with regard to the determination of key performance indicator (KPI) for physical layer security such as secrecy capacity [34], [35].…”

“…Measurements reported both in indoor [36], [23], [33], [29], and outdoor [40], [41] environments have shown that THz communications works also in non-line-of-sight (NLoS) situations by exploiting single or even multiple reflection or scattering processes, yielding a reduction of the received power level of compared to line-of-sight (LoS) as low as a few dB. Generally speaking, the pathloss coefficients for NLoS are in a similar range as those at cm-wave frequencies; however, shadowing is more severe, raising the probability of outage.…”

In recent years, terahertz (THz) systems have become an increasingly popular area of research thanks to their unique properties such as extremely high data rates towards Tb/s, submillimeter localization accuracy, high resolution remote sensing of materials, and remarkable advances in photonics and electronics technologies. This article traces the progress of THz measurements, antennas and simulations, from historical milestones to the current state of research and provides an outlook on the remaining challenges.INDEX TERMS Channel modeling, history, MTT 70th anniversary special issue, on-chip antennas, raytracing, THz communications, THz measurements and simulations.This article has been accepted for inclusion in a future issue of this journal.

“…For the production shop floor and storage area an access point (AP) scenario was simulated by placing the TX at a height of 2.7 m and the RX on a height of 1.5 m. The TX's alignment was changed throughout the channel measurement's execution, depending on the RX's position. For measurements in and around the metal hallway, the TX and RX were placed on the same height of 1.5 m [29].…”

“…Therefore, THz communications became more important in the last decade, emphasised by the IEEE Std 802.15.3d-2017 for point-to-point wireless THz links [2] and the allocation of a total of 137 GHz of spectrum between 275 and 450 GHz at the World Radio Conference 2019 [3]. Besides, several possible application fields for THz communications were investigated, such as THz links in data centres [4], vehicle-to-everything (V2X) communication for cars [5] and trains [6], urban outdoor scenarios [7] as well as indoor scenarios in offices [8], industry environments [9] and in an aircraft [10].…”

Future wireless communication systems at low terahertz frequencies (0.1-1 THz) suffer from high attenuation losses, and therefore, highly directive antennas are foreseen. As highly directive antennas have narrow beams, the alignment of the transmitter and the receiver is a crucial step in such systems. A device discovery approach using results from ray tracing (RT) combined with an iterative fine tuning is presented by the authors. A summary of previous investigations emphasises the benefits in terms of performance compared to an iterative approach. Furthermore, it indicates strong dependency of the RT output on the accuracy of the input data, that is, the environmental model. The authors extend the previous works by evaluating the impact of antenna characteristics. It is shown that the sidelobes lead to an error in the final alignment due to the superposition of the received power via multipath components, and equations to calculate the maximum error are given. Besides, the impact is evaluated with respect to sidelobe suppression. Here, equations to calculate the maximum error are given and it is shown that the sidelobes do not affect the alignment if the gain of the sidelobe is more than 30 dB lower than that of the mainlobe.
