Abstract: A network device for an intercom network for duplex audio communication between users of the intercom network has a housing and a communication module in or at the housing and that can establish a radio link for transmitting audio signals to and receiving audio signals from another user. The radio link is subject to the DECT protocol or another protocol, and the audio signals to the communication module is broken by reflection into a plurality of radio paths. Multipath interference is prevented or reduced by electronic elements including at least one equalizer for processing a plurality of audio signals received along the plurality of radio paths and performing a signal correction.
