Abstract:
Propagation mechanisms are very complex and diverse, because of the separation between the receiver and the transmitter, attenuation (reduction or loss) of the signal strength occurs. Field study will be conducted in amid north region of Libya (Bani Walid), which has high wind speed, and high attenuation loss, desert climate, and frequent dust and sand storms. This phenomenon actually influenced on wireless communication systems (GSM signal), neither the effect of the humidity on the complex permittivity nor the antenna height on the visibility, where by its effect on both attenuation and cross-polarization constants in this region. Besides the expectation of different chemical analysis of the dust and sand. These samples were collected from five location, every location had one level and sand was collected from a height of 2m, collect the meteorological data for the region of this study, e.g. visibility, wind speed and relative humidity, and height of towers from Libyana technical station. The analysis of these samples were done in two laboratories, one in university of Tripoli (AL-Fateh University), and the second in the Industrial Research Center in Tripoli. In the analysis, we were looking for the chemical and physically composition, the chemical composition of dust and sand had been got to compute complex permittivity, density, and chemical and physical properties analysis for the samples. Determine equivalent diameter, particles-size distribution, and axes ratio for collected samples; determine equivalent diameter, particles-size distribution, and axes ratio for collected samples. Compute the attenuation loss and cross-polarization discrimination (XPD) change due to the effect of sand and dust storms on wireless communication systems (GSM signal) which coverage in the studied region.
