Abstract
A plurality of radio relay stations 1 are connected so that bi-directional ring-like paths are made up of radio transmission paths. The respective radio relay stations 1 bidirectionally transmit data inputted from terminals placed thereunder onto the bidirectional ring-like paths respectively. The respective data are respectively received by radio relay stations 2 having data destination terminals placed thereunder along the bidirectional ring-like paths. Each radio relay station, which has received the data destined for the terminals placed thereunder from both directions, transmits earlier incoming data to each terminal placed thereunder and discards later incoming data.Thus, a radio relay system can be implemented which is capable of relaying data with a high degree of reliability.
