Abstract

La présente invention concerne un dispositif de réglage d'angle d'antenne, un système de réglage d'angle d'antenne, un procédé de réglage d'angle d'antenne et un dispositif de communications, selon lesquels l'angle d'une antenne peut être réglé vers une direction dans laquelle des ondes directes peuvent être reçues de manière plus fiable. À cet effet, une unité de génération d'informations d'angle 25 génère des informations d'angle indiquant la direction dans laquelle une antenne est orientée. Une unité de réception 23 reçoit des informations de réglage de direction indiquant la direction dans laquelle une autre antenne est orientée. Une unité de comparaison 24 compare les informations d'angle générées par l'unité de génération d'informations d'angle 25 et les informations de réglage de direction.
