“…The E-band (71-76 and 81-86 GHz) with a regulated bandwidth of 10 GHz is one of the future broadband communication bands [70]. The rain attenuation increases significantly with rising frequency, which restricts the path length of radio communication systems and limits the utilization of higher frequencies for LOS microwave links [69], [71], [72]. This makes the study of rain effects in the E-band crucial.…”

“…Other studies that covered longer distances are found in [71], [72], [77], [78], which conducted at 0.84, 1, 3.2 and 3.45 km links, respectively. The impact of rain on signal attenuation for 75 GHz and 85 GHz bands was analyzed and modeled in [71] based on two years field measurements along 840 m link in Madrid, Spain. The impact of rain at 71-76 GHz bands was based on ten months of measurements of a 1 km terrestrial link in Molndal, Sweden [77].…”

The high frequencies of millimeter wave (mm-wave) bands have been recognized for the fifth generation (5G) and beyond wireless communication networks. However, the radio propagation channel at high frequencies can be largely influenced by rain attenuation, especially in tropical regions with high rainfall intensity. In this paper, we present the results of rainfall intensity and rain attenuation in tropical regions based on one-year measurement campaign. The measurements were conducted from September 2018 until September 2019 at 21.8 GHz (K-band) and 73.5 GHz (E-band) in Malaysia. The rainfall intensity was collected using three rain gauges installed along a 1.8 km link. The rain attenuation is computed from the difference between the measured minimum received signal level (RSL) during clear sky and rain conditions. The measured rain rate and rain attenuation distributions are then analysed and benchmarked with several previous measurements and well-known prediction models such as the ITU-R P. 530-17. The rainfall rate results showed that the best agreement between the measured rainfall rate in Malaysia and the ITU-R PN.837-1 prediction value for Zone P is up to 0.01% of time (99.99% of time agrees well and only disagrees for 0.01% of time). For the E-band, the maximum measured rain attenuation exceeding 0.03% of the year is around 40.1 and 20 dB for 1.8 and 0.3 km links, respectively, at the maximum rain rate of 108 mm/h. For the K-band, the maximum rain attenuation exceeding 0.01% of the year is around 31 dB for the 1.8 km link. Finally, the rain rates exceeding 108 and 180 mm/h at 73.5 and 21.8 GHz, respectively, along the 1.8 km path caused an outage on our measurement setup. The rain rate of 193 mm/h and above caused an outage for the 0.3 km E-band link. The experimental data as well as the presented data analysis can be utilized for efficient planning and deployments of mm-wave wireless communication systems in tropical regions.

With the growing interest in millimeter-wave (mmW) communication links, especially for multi-gigabit backhaul applications, detailed studies on the performance limits in terms of achievable transmission distance and data rate, but also, and perhaps even more important, thorough investigations on the influence of different weather conditions gain in importance. In this paper we present a millimeter-wave monolithic integrated circuit (MMIC)-based transmit and receive front-end and ultra-broadband wireless data transmission experiments utilizing a 240 GHz carrier frequency in a long-range outdoor scenario as well as measurements inside a climatic wind tunnel. Data rates up to 64 Gb/s and various complex modulation formats are employed. While in the outdoor transmission, the link is tested in terms of maximum achievable transmission distance and data rate as well as alignment accuracy, in the climatic wind tunnel the influence of rain and fog in the transmission path is investigated in a defined and controlled environment.Index Terms-Atmospheric attenuation measurement, complex modulation, millimeter-wave (mmW) communication, mmW radio propagation, mmW monolithic integrated circuits (MMICs), point-to-point communication, radio links, wireless communication.

Millimeter wave (mmWave) communication is a key technology for fifth generation (5G) and beyond communication networks. However, the communication quality of the radio link can be largely affected by rain attenuation, which should be carefully taken into consideration when calculating the link budget. In this paper, we present results of weather data collected with a PWS100 disdrometer and mmWave channel measurements at 25.84 GHz (K band) and 77.52 GHz (E band) using a custom-designed channel sounder. The rain statistics, including rain intensity, rain events, and rain drop size distribution (DSD) are investigated for one year. The rain attenuation is predicted using the DSD model with Mie scattering and from the model in ITU-R P.838-3. The distance factor in ITU-R P.530-17 is found to be inappropriate for a short-range link. The wet antenna effect is investigated and additional protection of the antenna radomes is demonstrated to reduce the wet antenna effect on the measured attenuation.
