Abstract:
1. A radio network comprising: a core node connected to a wired network; relay nodes each relaying at least one of a down-link data packet transmitted front said core node and an up-link data packet directed toward said core node; a terminal station capable of transmission and reception of data packet with both of said core node and said relay nodes, a radio frequency band to be used in relaying communication data between said core node and said relay nodes and between said relay nodes and a radio frequency band to be used in access transmission of the communication data between said core node and said terminal station and between said relay node and said terminal station are different, and the radio frequency band to be used in relaying of the communication data is higher than the radio frequency band to be used in said access transmission of the communication data.
