Indoor propagation comparison between 2.45 GHz and 433 MHz transmissions

This paper describes a study of how 2.45 GHz electromagnetic waves propagate indoors. 2.45 GHz is a typical Bluetooth frequency. Propagation models with both one and several transmitters have been made using an advanced computer program. Furthermore, a model of the propagation of 433 MHz radio waves has been made and used as a standard point of comparison. To make sure that such models are reliable, the study was renewed using a real 2.45 GHz transmitter and receiver and then comparing the results to those given by one of the propagation models. Finally, the suitability of Bluetooth for indoor use is discussed.
