CONTROL UNIT, SYSTEM AND METHOD FOR SENDING AND RECEIVING RADIO SIGNALS IN SEVERAL FREQUENCY RANGES

摘要

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.

1. A control unit for forwarding first radio signals and second radio signals, comprising:
at least one first port for forwarding the first radio signals in a first frequency range and one second port for forwarding the second radio signals in a second frequency range; a third port connectible to a distributor network; a sensor for recognizing available frequency ranges in the distributor network; and a modulator/demodulator in order to convert, upon transmission of the second radio signals via the distributor network, the second radio signals to or from a further frequency range, said further frequency range being different from the first frequency range, and which contains at least partially at least one of the available frequency ranges.
