Abstract

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.
