Abstract
A theoretical model is developed to predict the propagation loss of UH F radio waves in large modem offices with low metallic partitions. It is found that in addition to free-space propagation loss the shadowing loss due to the blockage by the low partitions in the out-of-sight si tuation becomes the dominant one. The shadowing loss can be efficientl y formulated by using the theory of single or double knife-edge diffra ction. The model has been verified by an experiment conducted at 905 M Hz, 1.75 GHz, and 2.44 GHz in large offices. The model shows reasonabl e accuracy. (C) 1996 John Wiley & Sons, Inc.
