The invention relates to a transmitter and receiver device (1) for a cellular radio network, comprising a transmitter installation (6a) and a receiver installation (8a) located at a spatial distance to said transmitter installation (6areceiver (7) is connected to said transmitter installation (6a) and time-controls the transmission of transmission blocks by the installation (6a). The receiver installation (8a) is not provided with a time standard receiver. Instead, the receiver instal (8a), by intercepting the transmission signal emitted by the transmitter installation (6a) located in the same cell, generate signal for synchronizing the time of a timer of the receiver installation (8a).
