Abstract

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.
