Abstract: A system for extending wireless communication coverage includes a subnetwork comprising a set of interconnected nodes implementing a functionality of access point of one and the same wireless communication network. The system monitors messages exchanged during an address-resolution phase, and obtains therefrom an association between network address and MAC address of each device connected to the LAN and node of the subnetwork, and interface information representing an interface via which the message that made it possible to obtain said association was received. In order to identify a node closest to the target device, the system parses the address resolution tables while seeking the above-identified association corresponding to the target device and obtaining therefrom the associated interface information; and identifies the node closest to the target device as the node the address resolution table of which does not reference any node in the subnetwork in association with said interface information.

Abstract: A wireless communication coverage extension system comprises a backhaul subnetwork that includes a set of interconnected nodes. A plurality of nodes of the backhaul subnetwork implementing a functionality of access point of a same wireless communication network. To avoid conflicts of IP addresses, a monitoring of the presence of the main DHCP server is implemented, by a said node, to which the main DHCP server is connected. In the case where the first monitoring shows a disconnection of the main DHCP server, a backup DHCP server is activated in a node of the backhaul subnetwork. Then a general disconnection of the nodes of the backhaul subnetwork and of any device connected to the wireless communication coverage extension system is implemented. The IP address leases are then renewed by the backup DHCP server, following the general disconnection.

Abstract: A method for configuring a wireless communication coverage extension system is described. The latter comprises a backhaul subnetwork in tree form comprising a plurality of interconnected nodes. At least two nodes directly connected to an internet access gateway are identified among the nodes of the backhaul subnetwork. A single node is selected from the at least two identified nodes to be the node through which a configuration of the wireless communication coverage extension system is defined. The configuration of the wireless communication coverage extension system defined is then sent from the selected node to all the other nodes of the backhaul subnetwork.
