<P>PROBLEM TO BE SOLVED: To provide a radio communications system which uses a multi-hop communication method, and can reduce interference among channels, reduce influence of multi-path, and shorten transmission time of an electric wave. <P>SOLUTION: A radio communication system is characterized by that: communication by a multi-hop relay method with first antenna power (low output) is performed with a terminal station in a group managed by a base station; a group beacon with second antenna power (high output) is transmitted from the base station to the terminal station in the group; signals are transmitted/received with the second antenna power in an output period of the second antenna power provided in a group frame beginning with the group beacon; and a wide area beacon is transmitted with third antenna power (maximum output) in communication between base stations in different groups, where a plurality of group frames are included in a wide area frame beginning with the wide area beacon. <P>COPYRIGHT: (C)2013,JPO&INPIT |
