Ray optical simulation of indoor corridor propagation at 850 and 1900 MHz
In indoor propagation, the decline in field strength with distance has been modeled as inversely proportional to r/sup n/, where n is found empirically. In this paper, the field strength in a 50 m hospital corridor is computed by geometrical optics. The computed field strength is well represented as declining as 1/r at close distances and as 1/r/sup n/ farther away, with n chosen to minimize the error between the computed field and the r/sup n/ approximate model. Values of n are found for four wall constructions, at 850 and 1900 MHz.
