Mobility Model and Traffic Mapping for In-Building Radio Design

Abstract

A method to estimate and accurately distribute the building population and cellular traffic is presented and explained in this paper. This technique makes use of cellular traffic measurements to determine actual traffic on a per-existing-cell basis; these measurements are then used with characteristic mobility models of the population of the building in consideration, to produce traffic maps, which provide valuable information as how this traffic is distributed across the building.  This strongly augments the ability of a cellular network to minimize blocking for 2G, and to reduce unexpected noise rise effects and a much better allocation of system resources for 3G and other wireless technologies mainly used indoors.
