PROBLEM TO BE SOLVED: To provide a radio communication system capable of reducing a possibility that a radio apparatus receives a radio signal from an unintended direction or transmits a radio signal to an unintended direction.SOLUTION: The radio communication system includes: sensors D11 to D43 in which a state determination unit determines a state on the basis of a state signal from a state detection unit and a transmission/reception unit transmits or receives a radio signal; a receiver A for performing monitoring control of the sensors; and a plurality of relays B1 to B2 and C1 to C3 that mediate between the sensors and the receiver to relay a radio signal by constituting a plurality of communication hierarchies. |
