| Summary: | In this paper, real measurements were conducted to investigate the impact of rain on the
propagation of millimeter waves at 26 GHz. The measurements were accomplished using a microwave
fifth generation radio link system with 1.3 km path length implemented at Universiti Teknologi Malaysia
Johor Bahru, Malaysia. The implemented system consisted of Ericsson CN500 mini E-link, radio unit,
rain gauge, and data logger. The measurements were attained and logged daily for a continuous year, with
1-min time intervals. Next, the MATLAB software was used to process and analyze the annual rain rate
and rain attenuation, including for the worst month. From the analyzed results, it was found that at 0.01%
percentage of time, the rain rate was 120 mm/hr; while the specific rain attenuation was 26.2 dB/km and the
total rain attenuation over 1.3 km was 34 dB. In addition, the statistics acquired from the measurements for
the worst month were lower than what was predicted by the international telecommunication union (ITU)
model; around 51% and 34% for the rain rate and rain attenuation, respectively. The average percentage of
error calculated between the measurements and predicted results for the rain rate and rain attenuation were
143% and 159%, respectively. Thus, it can be concluded that the statistics for the worst month in Malaysia
is lower than what was predicted by the ITU model. |
