Prediction of Indoor-to-Outdoor Radio Wave Propagation Characteristics in the Office Environment at 2.4 GHz and 5.2 GHz Bands

摘要

The paper predicts indoor-to-outdoor radio wave propagation characteristics using computer simulations. We prepare four kinds of numerical model of an office building emulating a single floor with a wireless LAN access point. It is shown from the calculations that the electro- magnetic power passing through exterior wall surfaces is several percent of the power radiated from the access point and that the power through windows increases at the higher frequency.
