In this letter, we present an empirical model that predicts the building penetration loss at the 2-GHz band for high elevation angles involved in mobile communications served by high altitude platform stations. The model takes into account the elevation angle of the specific building with respect to the position of the platform. The penetration loss is found to be an increasing function of the elevation angles for a building with concrete walls and normal window size. The predicted values are compared with a ray-tracing simulation and a measurement campaign and good agreement is reported.Index Terms-Building penetration loss, electromagnetic propagation, empirical model, outdoor-to-indoor propagation.

An empirical model for predicting building penetration loss at 2 GHz for high elevation angles

Antennas Wirel. Propag. Lett.

2003

“…The case of outdoor to indoor propagation prediction at high elevation angles has been scarcely addressed [1, 2,3] , since the mobile satellite systems-operating at these angles-are not intended to provide services into buildings. Moreover, no direct relationship between the elevation angles and the building penetration loss has been reported.…”

2 GHz outdoor to indoor propagation at high elevation angles

The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications

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 dihctions from building edges and rooftops. This approach concludes that the penetration loss is an increasing function of the elevation angles.

2 GHz outdoor to indoor propagation at high elevation angles for mobile communications served by high altitude platform stations

Global Telecommunications Conference, 2002. GLOBECOM '02. IEEE

Abstrnd-High Altitude Platform Stations have been recently proposed as a new means of providing International Mobile Communications (IMT-2000). One critics1 issue that has not been resolved yet is the possibility of providing indoor services. This paper examines the penetration into buildings loss s t high elevation angles. Two approaches are followed: An empirical model is presented and evaluated through comparison with two measurement campaigns Furthermore, B 3-D ray-tracing tool was developed in order to rimulate a specific environment of 11 buildings sod take into account parameters not modeled by the empirical method, such as rooftop diffractions. Both approaches conclude that the penetration loss is an increasing function of the elevation angle, but the range of values obtained shows that indoor coverage is feasible.
