Abstract

L'invention concerne un répéteur passif permettant de constituer un réseau local avec des dispositifs de communication électroniques sans fil bien qu'ils soient séparés par des barrières et des obstacles, ce qui autrement atténueraient un signal radio entre lesdits dispositifs électroniques. Une première et une seconde antennes sont connectées par un guide d'onde qui peut traverser ou entourer la barrière ou l'obstacle situé entre les dispositifs électroniques. L'antenne de chaque guide d'onde collecte ou retransmet un signal radio de manière multidirectionnel, ce qui permet au répéteur de communiquer avec ledit signal radio à travers la barrière située entre les dispositifs de communication électroniques sans atténuation dudit signal radio.
