Abstract

L'invention concerne un système de communication de groupe (GKS) qui comporte au moins deux dispositifs de communication (K1 - K6) et en particulier trois ou quatre ou cinq ou six dispositifs de communication (K1 - K6). Les dispositifs de communication (K1 - K6) communiquent sans fil dans un réseau radioélectrique (FNW). Le réseau radioélectrique (FNW) fonctionne comme réseau radioélectrique (FNW) selon une norme radioélectrique à courte portée. Une communication vocale est établie entre un groupe de personnes prioritairement par le biais du réseau radioélectrique. Chaque personne du groupe est en possession d'un dispositif de communication.
