Abstract
A distributed antenna system for transceiving radio signals in several frequency ranges is described. The system comprises a control unit with at least one first port for forwarding first radio signals in a first frequency range and one second port for forwarding second radio signals in a second frequency range. A plurality of remote units is connected to the control unit via a distributor network. The remote units have first antenna elements for transceiving the radio signals in the first frequency range and second antenna elements for transceiving the radio signals in the second frequency range. The control unit comprises a modulator for converting the second radio signals to a further frequency range and the remote units have a demodulator for converting the second radio signals from the further frequency range to a different frequency range.
