A study on outdoor to indoor penetration path loss at 2 and 5 GHz

Abstract

The 5-th generation of mobile communication systems (5G) are being actively investigated all over the world. Various systems exist when considering the microwave bands after the introduction of the 5G systems. It is very important to consider the microwave propagation characteristics in order to minimize possible interferences among systems. In this paper, we propose a simple outdoor to indoor (O2I) propagation model based on the 2 and 5-GHz bands. The proposed model focuses on the variation in incident angle on a vertical plane when the microwaves move from O2I environments. This model shows realizes the additional loss by using only angles on the vertical plane.
