TLDR
In this paper, a millimeter wave propagation experiment at 103 GHz (2.9 mm) on a propagation path of 390 m was conducted and the results were compared with the rain attenuation calculations from the Marshall-Palmer, Best, Joss-Thomas-Waldvogel and Weibull distributions for raindrop-size.Abstract:
We have conducted a millimeter wave propagation experiment at 103 GHz (2.9 mm) on a propagation path of 390 m. The results were compared with the rain attenuation calculations from the Marshall-Palmer, Best, Joss-Thomas-Waldvogel and Weibull distributions for raindrop-size. It has been shown that the Weibull distribution has a good agreement with the experiments.read more

Link Budget Analysis for Terahertz Fixed Wireless Links
TL;DR: High data rates can only be transmitted via these links if transmitter and receiver antennas with very high gains are used, and this requires an adaptive control of mechanical fluctuations.

Rain Attenuation in Millimeter Wave Ranges
Zhao Qingling,Jin Li +1 more
TL;DR: In this paper, a short-range 35 GHz radio link was used to measure rain specific attenuation with simultaneous measurement of rain rate distribution, and an empirical model derived from these measurements is suggested in order to observe and investigate the attenuation caused by rains in shortrange communications.

Experimental comparison of terahertz and infrared data signal attenuation in dust clouds
TL;DR: Attenuation by the presence of dust degrades the IR channel but exhibits almost no measurable impact on the THz signal, and numerical simulations of THz attenuation with different dust concentrations agree with the measured results.

Experimental comparison of performance degradation from terahertz and infrared wireless links in fog
TL;DR: A lab setup for analyzing impairments of terahertz (THz) and infrared (IR) free space links caused by local refraction index changes in the signal's propagation paths that could be induced by turbulence, particles, humidity, etc.

Rain attenuation at millimeter wavelength of 1.33 mm
TL;DR: In this article, specific rain attenuation values calculated by using the four empirical raindrop-size distributions, that is, the Marshall and Palmer, the Joss, Thams and Walgvogel, the Ihara, Furuhama and Manabe, and the Weibull raindrop size distributions, were compared with the millimeter wave measurement at 225 GHz (1.33mm) was compared with their calculations.
