Sustaining good quality of service, in mobile systems, is indeed a direct result of the efficient pre - planning process. Accurate path loss prediction and estimation is one important step toward best deployment of such systems. Recently Terrain roughness parameters are considered essential factors in realizing reliable path loss estimation. In this work, the slope (S) of the route undergone by the...
Since the first publication of Hata Path loss model in 1980, it was imposed by the author that the model is valid for distances more than 1 km. Therefore, Researchers have categorized the model to suit Macro cells of distances from 1 km up to 20 km. Many recent and older researches have argued that Hata model can be used even in micro cell distances down to tens of meters from the transmitter under...
This paper proposes a new terrain based formula to correct propagation loss model originally proposed by Hata for the 900 MHz band. This formula consists of an estimator of the standard deviation (σ) along the measuring path in west of Amman city, Jordan. The estimator is calculated by a quadratic regression formula to reflect terrain roughness of the path taken. This estimator is used as a correction...
