1. A method for selecting a node in a local area network comprising nodes allowing an extension of wireless communication coverage in order to increase the range of the local area network by coordinating a plurality of access points incorporated in the nodes, the nodes being interconnected by an access-point interface of a backhaul subnetwork and a client interface of the backhaul subnetwork of another node, each node in the backhaul subnetwork emitting at least one wireless network called fronthaul network, the nodes comprise at least two radio interfaces making it possible to communicate on two different channels, wherein the method causing an item of equipment for associating itself with the local area network to perform,
obtaining, from each node allowing an extension of wireless communication coverage, and for each radio interface of the at least two radio interfaces, information comprising at least one item of information representing a hierarchical level of the node as well as an item of information indicating whether a client interface of a radio interface of the node of the backhaul subnetwork is connected to an access-point interface of the backhaul subnetwork of a node of a higher hierarchical level,
selecting, from the information obtained and from the nodes allowing an extension of coverage for which the information comprising at least one item of information representing the hierarchical level of the node and the information indicating whether the client interface of the radio interface of the node of the backhaul subnetwork is connected to an access-point interface of the backhaul subnetwork of a node of a higher hierarchical level has been obtained, the node allowing an extension of wireless communication coverage with which the equipment associates itself.
