2 GHz outdoor to indoor propagation at high elevation angles

چکیده
The case of outdoor to indoor propagation prediction at high elevation angles has been scarcely addressed and no direct relationship between the elevation angles and the building penetration loss has been reported. High Altitude Platform Stations a new means of providing International Mobile Telephony (IMT-2000)-will be operating at high elevation angles. This paper examines the impact of the high elevation angles in the propagation mechanism and the penetration into buildings loss. A 3-D ray-tracing tool was developed in order to simulate a specific environment of 11 buildings and take into account parameters, such as diffractions from building edges and rooftops. This approach concludes that the penetration loss is an increasing function of the elevation angles. KeywordsHAPS, Penetration, Loss, High Elevation Angles

A run-time efficient three-dimensional radio propagation prediction model is presented in this paper. The model allows mobile network operators to predict the outdoor and the outdoor-to-indoor coverage in dense urban areas using one general prediction model. It integrates almost all relevant propagation phenomena in dense urban areas with an accuracy comparable to the results of dedicated predi...

In this paper, a three dimensional geometrical scattering channel model for indoor and outdoor wireless propagation environments is introduced. It is based on the assumption that the scatterers are distributed within a spheroid, in which the mobile station and base station are located at the spheroid’s foci. This model captures both the spatial and temporal statistical distributions of the rece...
