Abstract

For microcellular system design, we have enhanced a well‐known waveguide model for propagation‐loss prediction along an LOS propagation path in a tunnel. It is reported in this letter. The enhancement involves a more accurate calculation of the tilt loss, the distinction of the two propagation regions, and the suggestion of using the free‐space model for one region and the waveguide model for the other. The enhancement is demonstrated with examples. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 10–12, 2001.

## Abstract This paper presents a new model for propagation‐loss prediction in indoor mobile communications. It uses the free‐space loss model added to an empiric function (based on the Padé approximant), and a term that describes the signal randomness (typical of the RF propagation). In order to v
