Characterization of indoor penetration loss at ISM band

Abstract

The potential implementation of wireless radio local area networks and personal communication services inside buildings requires a thorough understanding of signal propagation in a building. In this paper in-building penetration loss measurements, at 2.4 GHz. (the ISM band) have been presented for materials used in indoor environments. To obtain the data, measurements were performed at 160 MHz bandwidth centered on 2.4 GHz using a vector network analyzer. These measurements may aid in the development of future in-building wireless networks in this band.
