Abstract: A device for transmitting and receiving signals for a radio network comprises an air interface; a MIMO antenna; and an antenna-side frequency conversion device provided between the air interface and a home distribution network. The antenna-side frequency conversion device comprises at least one frequency converter via which the receive signals obtained via the at least one polarization of the dual-polarized antenna or via at least one of the at least two antennae can be converted into an intermediate frequency range that is unused and/or free in the home distribution network. At least one receive-side frequency back-conversion device is provided between the home distribution network and a receiver. The receive-side frequency back-conversion device is configured in such a way that a frequency back-conversion of the frequencies converted into an unused frequency range can be fed back into the received frequency range.
