Rain is the major challenge to design reliable earth to satellite microwave link at higher frequencies in tropical regions. Site diversity is one of the techniques used to mitigate this problem. Hodge and ITU-R Site Diversity Gain Models and ITU-R Diversity Improvement Factor Model are analyzed based on measurements at two locations in Malaysia. The measured rain intensity at IIUM and UKM campus for...
Femtocell gains the interest of more than 160 mobile operators around the world. For the reason that femtocell improve the signal power inside the building and reduce the main network traffic and thus increase the capacity. However, deployment the femtocell may cause interference to the existing network. Therefore, understanding the behavior of indoor signal propagation is essential to minimize the...
This paper aims to investigate the utilization of the Synthetic Storm Technique (SST) to convert rain rate time series to rain attenuation time series using the ITU-R P.839, Stutz man and Bryant rain height models. Furthermore, the study aims to compare the actual rain attenuation with that predicted by the SST using the three above-mentioned rain height models based on rain rate and rain attenuation...
Rn is the major challenge to design reliable earth to satellite microwave link at higher frequencies in tropical regions. Site diversity is one of the techniques used to mitigate this problem. Hodge Site Diversity Gain Model, ITU-R Site Diversity Gain Model and ITU-R Diversity Improvement Factor Model are analyzed based on rainfall data measured in Malaysia and four locations in Kuala Lumpur and MEASAT3A...
The empirical propagation path loss models have important influence in mobile communication systems design. They become important tools in both research and industrial communities owing to their speed of implementation and their limited dependence on detailed knowledge of the terrain. The mobile services are increasing rapidly and hence the mobile stations are required to design with best quality...
