Abstract (en)
[origin: DE19757235A1] The invention relates to a conducting system for a building or for one or several rooms in a building, comprising a central unit and at least two components linked to the central unit by radio. The central unit receives signals from the components or transmits signals to the components. The signals are transmitted within a predetermined frequency range. To improve the reliability of signal transmission each signal is transmitted on at least two different frequencies within the frequency range. In addition, at least one of these frequencies is located outside a partial frequency range of the frequency range, which is usually used by other devices communicating by radio. Redundant signal transmission on the one hand and targeted frequency selection on the other hand improve the reliability of signal transmission.
