A theoretical model is developed to predict the propagation loss of UHF radio waves in large modern 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 situation becomes the dominant one. The shadowing loss can be efficiently formulated by using the theory of single or double knife‐edge diffraction. The model has been verified by an experiment conducted at 905 MHz, 1.75 GHz, and 2.44 GHz in large offices. The model shows reasonable accuracy. © 1996 John Wiley & Sons, Inc.
