Abstract:
1. A communication method for a radio LAN system providing communication at a first transmission rate, said method comprising: time-divisionally distributing a first signal of said first transmission rate into n−1 second signals, wherein n is an integer≧3; respectively converting said n−1 second signals into n−1 third signals of a second transmission rate less than said first transmission rate; transmitting said n−1 third signals of said second transmission rate through radio transmission paths between n−1 radio base stations and a terminal station connected with at least one terminal unit, wherein said radio LAN system further comprises at least one redundant radio base station n; transmitting a fourth signal through a radio transmission path between said terminal station and said at least one redundant radio base station n, data of said fourth signal having a given relationship with data in signals transmitted between at least, wherein k≦n−1, radio base stations of said n−1 radio base stations and said terminal station; and compensating, when at least one transmission path between said at least k radio base stations and said terminal station is interrupted, data of the signal to be transmitted through an interrupted transmission path based on said data of said fourth signal transmitted between said at least one redundant radio base station n and said terminal station.
