Abstract
A method and a device for reconfiguring a first interconnection of a first node with a second node of a backhaul subnetwork in a local area network including a plurality of nodes, the first and second nodes being interconnected by a radio connection in a first frequency band. A controller node: selects a third node of the local area network, the third node being different from the first and second nodes, establishes a second interconnection between the first and third nodes by a radio connection in a second frequency band different from the first frequency band, deletes the first interconnection when the second interconnection is established.
Claims7
A method for reconfiguring a first interconnection of a first node with a second node of a backhaul subnetwork in a local area network comprising a plurality of 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 integrated in the nodes, the first and second nodes being interconnected by a radio connection in a first frequency band, characterised in that the method comprises the steps, performed by a controller node, of:
- selecting a third node of the local area network, the third node being different from the first and second nodes, the nodes of the backhaul subnetwork are connected to one another by means of a mesh structure in tree form, the first node serving as relay between at least one node of higher hierarchical level in the tree and at least one node of lower hierarchical level in the tree, and the third node is not a node of lower hierarchical level for which the first node serves as relay,
- establishing a second interconnection between the first and third nodes by a radio connection in a second frequency band different from the first frequency band,
- deleting the first interconnection when the second interconnection is established,
- and following the establishment of the second interconnection:
- checking whether establishing the second interconnection creates two pathways for transferring data between two nodes of the backhaul subnetwork and, if so
- interrupting the transfer of data at a logic level on one of the two pathways while maintaining the physical pathway of the second interconnection.
