A method of constructing a radio network that enables the user to select an arbitrary radio communication apparatus as a control station and the thus selected radio communication apparatus preferentially constructs the radio network, wherein the radio communication apparatus that is desired to be arranged as a control station is set up so that it has the function of preferentially becoming a control station in advance. In case several radio communication apparatuses are designated as control stations, any of the radio communication apparatuses is selected as a control station based on the number of radio communication apparatuses with which the designated radio communication apparatus can communicate.
