Summary:PROBLEM TO BE SOLVED: To provide a communication network for realizing inexpensive and easy data communication by using radio communication. SOLUTION: Radio terminals 2 are distributed and installed in a mesh shape with a specified interval and a radio mesh 1 is constituted. The radio terminals 2 adjacent to each other are communicable, and by transferring and relaying packet data between the adjacent radio terminals 2, data are transferred between optional terminals. Also, as a congestion processing, the radio terminal 2 changes a transmission speed corresponding to a data amount inside a network and changes a transfer speed by a transmission destination. Further, at the time of data transmission, directivity is provided. Also, for the collision of counter radio waves, plural channels are provided and the data are transmitted from the two or more channels. Further, the respective radio terminals 2 are provided with a function for selecting the closest one of plural connection points. Also, a server for maintenance management can be connected to the radio mesh 1 as well.
