PROBLEM TO BE SOLVED: To provide a self-configuring adaptive type three-dimensional radio network for performing high bandwidth data transmission to an addressed device while preventing interference and intervention. SOLUTION: The self-configuring adaptive type three-dimensional radio network comprises a plurality of access points, and first access points 11, 20a and 80 receive media data from a source and transmits to the downstream at a first data rate. A plurality of additional access points 20b, 20c, 60a and 60b are arranged in a building, and each of them comprises an upstream transmitting/receiving device 74 for receiving a media content on a first channel, and a downstream transmitting/receiving device 75 for re-transmitting on a second channel substantially at the first data rate; and the media content is transmitted to the addressed devices 25 and 81. The additional access points are provided with additional transmitting/receiving devices 76 for transmitting a media content to one or a plurality of the addressed devices.
