Abstract
The wireless relay apparatus (100) capable of high-quality transmission of data includes a wireless control unit (110) and a data link communication unit (101) which wirelessly receive and transmit data wirelessly, a congestion status determining unit (104) which determines whether or not a congestion caused by radio wave interference occurs in the wireless relay apparatus (100), a data flow determining unit (105) which identifies a flow of data transmitted and received by the wireless relay apparatus (100) and determines whether the flows intersect in the wireless relay apparatus (100), when the congestion status determining unit (104) determines that there is a congestion, and a transmission parameter adjustment unit (106) which adjust transmission characteristics of a type according to a result of the determination by the data flow determining unit (105), among types of transmission characteristics of radio used in at least one of the wireless control unit (110) and the communication apparatuses (100).

23. A program, being embodied on a non-transitory computer-readable medium, for relaying, by a relay apparatus, data to be transmitted and received, between at least two communication apparatuses among communication apparatuses that communicate with each other wirelessly, said program which, when loaded into a computer, causing the computer to execute:
-
transmitting and receiving the data to and from the relay apparatus wirelessly; determining, when it is determined that there is a communication failure in the relay apparatus caused by a radio wave, whether or not flows intersect each other in the relay apparatus; and adjusting transmission characteristics of a type according to a result of the determination in said determining on whether or not the flows intersect each other, among types of transmission characteristics of radio used in at least one of the communication unit and the communication apparatuses.
