摘要： A radio communication system includes a gateway apparatus and a plurality of radio stations performing radio communication. The gateway apparatus includes, a generation unit that generates allocation information on one or more individual channels each allocated individually to one of a plurality of radio stations; and a transmission unit that transmits the generated allocation information, and the plurality of radio stations each of which comprising, a receiving unit that receives the allocation information; and a data transmission unit that performs data transmission through the one or more individual channels when information indicating an own station is included in the received allocation information, and performs data transmission by random access through a channel other than the one or more individual channels in a radio frame when information indicating the own station is not included in the received allocation information.

摘要： A wireless communication apparatus includes: an estimating section to estimate a positional relationship between a destination node and a node; a first determination section to set an electric power larger than or equal to minimum power as a first transmission power if the node is estimated to be located in a first area, the minimum power being detected by a node at the largest distance from the node in the first area; a second determination section that set an electric power smaller than a minimum power as a second transmission power if the node is estimated to be located in an area other than the first area, the minimum power being detected by the destination; and a transmitting section to transmit data to the destination node with the first transmission power or the second transmission power.
