MODELING AND MEASUREMENT OF UHF RADIO PROPAGATING THROUGH FLOORS IN AMULTIFLOORED BUILDING

A general three-dimension theoretical model is developed to predict th e 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 reasonabl e agreement. It is found that the floor, lateral beams and the walls a round the receiver are the major construction features to affect the e stimation of the penetration loss through floors.
