Abstract:
1. A distributed antenna system for distributing MIMO signals for at least one MIMO service in a distributed antenna system (DAS), comprising: a) a remote unit configured to receive and distribute non-overlapping frequency MIMO downlink signals of at least one MIMO service; b) at least one antenna unit configured to receive the non-overlapping frequency MIMO downlink signals of the at least one MIMO service and frequency shift the non-overlapping frequency MIMO downlink signals into native frequency MIMO downlink signals; c) a single coaxial cable used to carry the non-overlapping frequency MIMO downlink signals of the at least one MIMO service between the remote unit and the at least one antenna unit; wherein the at least one antenna unit is operatively coupled to at least two MIMO antennas, the at least one antenna unit is configured to transmit the native frequency MIMO downlink signals via the at least two MIMO antennas.
