A transmitter network is provided with at least two transmitters which transmit in a same frequency range. In a unicast-transmission mode of the transmitter, the transmitters transmit unicast information packets (UC) in subsequent first time intervals. The at least two transmitters further simultaneously transmit in a broadcast mode or multicast mode, respectively, broadcast- or multicast information (BC/MC) in second time intervals that lie in between first time intervals, the broadcast information or multicast information, respectively, transmitted by the transmitters in a second time interval being substantially equal and being transmitted by the transmitters substantially time synchronous. The invention also relates to a transmitter and a receiver in the transmitter network.
