Prediction of breakpoint distance in microcellularenvironments

Abstract

Experimental studies of path loss distance dependency in line-of-sight microcellular propagation almost always show a dual-slope behaviour. However, there is disagreement in the literature over the best way to predict the breakpoint distance that delineates the change in path loss distance dependency. A new breakpoint equation is presented, the predictions of which are in excellent agreement with breakpoint distances observed in various propagation studies.
