Intercom method between at least three handsets in a local radiocommunication network and handset therefor

摘要

The direct local network interconnection process has a base and three handsets (C1,C2,C3). The first handset can be transformed to a base. The first handset has a mechanism placing a mark on its transmission channel whilst transmitting an audio message. The other two handsets search and recognise the mark, then transmit the audio signal contents on the loudspeaker.
