Modelling and measurement of UHF radio propagating through floors in a multifloored building

A general three-dimension theoretical model is developed to predict the path loss of UHF radio propagation through floors in a multifloored building. The computed propagation loss is compared with the measured value of 900 MHz, 1.4 GHz, 1.9 GHz, and 2.44 GHz and gives a reasonable agreement. It is found that the floor, lateral beams and the walls around the receiver are the major construction features to affect the estimation of the penetration loss through floors.
