Abstract: Responsive to a processor of a first intercom unit establishing a wireless data channel with one or more second intercom units of a plurality of intercom units in a wireless network, and responsive to an encoder of the first intercom unit repeatedly encoding, during a repeated time interval, data to be transmitted to the one or more second intercom units over the wireless data channel while pausing the wireless data channel such that the first intercom unit does not transmit the encoded data during the repeated time interval, the processor may receive an indication to un-pause the wireless data channel. A network controller of the first intercom unit may wirelessly transmit the data last encoded by the encoder during the repeated time interval to the one or more second intercom units.
