In one embodiment, a repeater for wireless communication is provided. The repeater comprises: circuitry configured to receive first and second MIMO-coded information channels at a first frequency; a converting device configured to convert the first MIMO-coded information channel to a second frequency using information from a test receiver configured to determine unused frequency ranges situated outside frequency bands allocated to mobile radio for wireless communication, the test receiver communicatively coupled with the converting device, the converting device configured to convert the first MIMO-coded information channel to the second frequency in at least one communication direction, the second frequency within the unused frequency ranges situated outside the frequency bands allocated to mobile radio; and circuitry configured to transmit the first and second MIMO-coded information channels in the at least one communication direction, wherein the first and second MIMO-coded information channels are transmitted using different frequencies compared to each other.

Wireless communications network using frequency conversion of MIMO signals

Communication network () for wireless communication, comprising a base station (), a wireless terminal () and at least one repeater () which is connected between the base station () and the wireless terminal (), the base station () being configured for transmitting and receiving a communication signal on multiple information channels, the terminal () being configured for transmitting and receiving a communication signal on multiple information channels, and the repeater () being configured for receiving, passing through and retransmitting communication signals on multiple information channels, and contains a converting device () for frequency conversion of at least one information channel passed through, a test receiver () being additionally comprised which is configured for determining unused frequency ranges for wireless communication, the test receiver () being connected to the converting device () of the repeater (), the converting device () being configured for carrying out the frequency conversion in at least one communication direction (UL, DL) to a frequency from the unused frequency ranges, and the repeater () being configured for transmitting the communication signal wirelessly with the at least one frequency-converted information channel in the at least one communication direction.
