Title
(EN) REDUCTION OF ELECTROSMOG IN WIRELESS LOCAL NETWORKS
(FR) REDUCTION D'ELECTROSMOG DANS DES RESEAUX LOCAUX SANS FIL
Abstract
(EN)
A method and system for reduction of electrosmog in wireless local networks, one or more mobile network units (1) communicating with a base station (2) of a wireless local network (5). After a predefinable time interval without connecting signal, the base station (2) changes over from the normal transmitting−receiving mode into a sleep mode, in which sleep mode no beacon signals and/or other radio frequency signals are transmitted from the base station (2). If a mobile network unit (1) requires a network connection, it transmits an alert signal, and, upon receiving the alert signal of the mobile network unit (1), the base station transmits beacon signals to the mobile network unit (1) and changes over into the normal transmitting−receiving mode.

La présente invention a trait à un procédé et un système de réduction d'électrosmog dans des réseaux locaux sans fil, une ou plusieurs unités de réseau mobiles (1) communiquant avec une station de base (2) d'un réseau local sans fil (5). Après un intervalle de temps pré-définissable sans signal de connexion, la station de base (2) passe du mode normal de transmission/réception en un mode sommeil, dans lequel mode sommeil il n'y a aucune transmission de signaux de balise et/ou autre signaux de radiofréquence depuis la station de base (2). Si une unité de réseau mobile (1) requiert une connexion de réseau, elle transmet un signal d'avertissement, et, lors de la réception du signal d'avertissement de l'unité de réseau mobile (1), la station de base transmet des signaux de balise à l'unité de réseau mobile (1) et passe en mode normal de transmission/réception.
