Abstract
Radio signals are communicated on spatially separate radio paths across a doorway of an elevator. Signal strengths of the radio signals are measured and used to determine traffic served by the elevator. In this way traffic boarding and leaving the elevator may be measured when more than one unit of traffic, for example people, pass through the doorway simultaneously.
