Interpolation of communication distance in urban and suburban areas

This paper is concerned with a numerical method to interpolate the distribution of communication distance function in urban and suburban areas. According to the 1-ray model, it is shown that the propagation order of distance β depends only on the height of transmitting antenna and the amplitude modification factor α can be derived from the path loss obtained theoretically or experimentally. We propose a numerical method for estimating communication distance functions in urban and suburban areas by employing the path loss computed by the Okumura-Hata model. Numerical examples are shown to demonstrate the effectiveness of the proposed method.
