Abstract: A radio communication system according to the present invention includes a plurality of nodes that collect data of apparatuses and an access point that collects the data of the plurality of nodes. The access point arranges the plurality of nodes into a plurality of groups including nodes, each of which can receive radio waves transmitted from one another, the number of the nodes being equal to or smaller than a number with which interference avoidance of radio by an access method for avoiding congestion efficiently functions. The access point transmits a polling packet for granting a transmission right to each of the groups. When determining that a transmission right is granted to the group to which the plurality of nodes belong, the plurality of nodes transmit the data to the access point while avoiding interference with the other nodes in the group according to the access method.
