PROBLEM TO BE SOLVED: To allow a control signal in an elevator to be stably transmitted by radio.SOLUTION: A radio transmission system includes: a plurality of first radio devices being activated at a first frequency band and corresponding to each of a plurality constituents of an elevator outputting a control signal used for controlling the elevator; and a plurality of second radio devices being activated at a second frequency band being a frequency band higher than the first frequency band and corresponding to each of the plurality constituents of the elevator outputting the control signal.SELECTED DRAWING: Figure 1
【課題】エレベータにおける制御信号を無線により安定して伝送可能にすること。【解決手段】実施形態によれば、無線伝送システムは、第1の周波数帯にて動作し、エレベータを制御するために用いられる制御信号を出力する当該エレベータの複数の構成要素の各々に対応する複数の第1の無線装置と、第1の周波数帯より高い周波数帯である第2の周波数帯にて動作し、制御信号を出力するエレベータの複数の構成要素の各々に対応する複数の第2の無線装置とを含む。【選択図】図1
