  Wireless connections are a communication channel used to support different
applications in our life such as microwave connections, mobile cellular
networks, and intelligent transportation systems. The wireless communication
channels are affected by different weather factors such as rain, snow, fog,
dust, and sand. This effect is more evident in the high frequencies of the
millimeter-wave (mm-wave) band. Recently, the 5G opened the door to support
different applications with high speed and good quality. A recent study
investigates the effect of rain and snow on the 5G communication channel to
reduce the challenge of using high millimeter-wave frequencies. This research
investigates the impact of dust and sand on the communication channel of 5G
mini links using Mie scattering model to estimate the propagating wave's
attenuation by computing the free space loss of a dusty region. Also, the
cross-polarization of the propagating wave with dust and sand is taken into
account at different distances of the propagating length. Two kinds of mini
links, ML-6363, and ML-6352, are considered to demonstrate the effect of dust
and sand in these specific operating frequency bands. The 73.5 GHz (V-band) and
(21.5GHz (K-band) are the ML-6352 and ML-6363 radio frequency, respectively.
Also, signal depolarization is another important radio frequency transmission
parameter that is considered heroin. The numerical and simulation results show
that the 5G ML-6352 is more effect by dust and sand than ML6363. The 5G toolbox
is used to build the communication system and simulate the effect of the dust
and sand on the different frequency bands.
