Claim 14:
15. A master node device, intended to be used in a wireless communication network comprising a backhaul network interconnecting node devices and intended to extend a radio coverage of a wireless fronthaul network by using a plurality of access points of the wireless fronthaul network,
wherein a same first communication channel, selected by the master node device, is used in the backhaul network for interconnecting said node devices,
wherein the master node device comprises circuitry causing the master node device to perform:
making an evaluation of transmission conditions of its radio environment;
calculating, for each communication channel available to said master node device, a score representing a quality of transmission via said communication channel according to the evaluation made, and
when, when, from the point of view of the master node device or of another node device of the backhaul network, at least one second communication channel shows a better score than the first communication channel, the master node device further comprises circuitry causing the master node device to perform:
obtaining, from each other node device of the backhaul network, the score of the first communication channel and the score of at least one said second communication channel, for making an evaluation of change of communication channel; and
deciding to change, or not, communication channel used in the backhaul network according to the scores obtained.
