An intercom system enabling a plurality of users to listen to and at least one user to speak to and listen to a remote user. A base station communicates with the remote user. A plurality of ear pieces is wearable by the plurality of users, each of the plurality of ear pieces being capable of wirelessly communicating with the base station. Each of the plurality of ear pieces is capable of listening to the base station within a first range of the base station. At least one of the plurality of ear pieces being capable of wirelessly speaking to the base station within a second range of the base station. The second range is larger than the first range. Thus, one of the plurality of users wearing at least one of the plurality of ear pieces may listen and talk with the remote user only within the first range of the base station and the remainder of the plurality of users wearing the remaining ear pieces may only listen to the remote user outside of the first range of the base station but inside of the second range of the base station.

La présente invention concerne un système d'intercommunication qui permet à une pluralité d'utilisateurs d'écouter et à au moins un utilisateur de parler à un utilisateur distant et de l'écouter. Une station de base communique aussi avec cet utilisateur distant. Une pluralité d'oreillettes peuvent être portées par la pluralité des utilisateurs, chacune des ces oreillettes étant capable de communiquer sans fil avec la station de base. chacune de ces oreillettes donne la possibilité d'écouter la station de base dans une première portée de la station de base. Au moins une de ces oreillettes donne la possibilité de parler sans fil avec la station de base dans une seconde portée de la station de base. cette seconde portée est plus grande que la première portée. ainsi, un des utilisateurs portant au moins une des oreillettes peut-il écouter et parler avec l'utilisateur distant uniquement dans la première portée de la station de base et les utilisateurs restants qui portent les oreillettes restantes ne peuvent écouter cet utilisateur distant qu'en dehors de la première portée de la station de base et dans la seconde portée de la station de base.
