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.

The client node is associated with one level among a plurality of levels. The method includes determining a connection quality indicator and determining a connection quality threshold dependent on the level. If the connection quality indicator compared with the threshold indicates a poor relative quality of the connection then incrementing the level or executing a handover method, otherwise if, and as long as, the connection quality indicator compared with a threshold determined according to the level immediately below the level associated with the client node indicates a better connection quality, then decrementing the level.

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.

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.

If the second gathering node is different from the first gathering node, then to each gathering node, except for the second gathering node, a command to refuse association with the client node is sent.

Abstract: A wireless communication system has an access point managing a first wireless local area network. To transmit the frame, the access point: obtains data to be transmitted in multicast mode; obtains data to be transmitted in unicast mode; and constructs a physical-layer header including: in a common signalling field, an identification of each channel resource intended to be used for making the frame transmission, whether this be for the data to be transmitted in unicast mode or in multicast mode; and, in each field in a series of specific signalling fields, information representing an association between a channel resource identifier used and a unique identifier of the destination concerned or group of destinations concerned. Thus each destination can determine each channel resource to listen to in order to receive the data that are addressed to it, whether this be in unicast mode or in multicast mode.

Abstract: An item of ONU equipment configures itself to communicate by a first transport system with OLT equipment in an optical access network, and starts a synchronisation for the first transport system and transmits by means of the first transport system. The ONU equipment transmits, via a protocol layer supervising any transport system of the optical access network, without waiting for the end of the synchronisation for the first transport system, information dependent on identifiers of the user equipment and the first transport system. When the transport system to be used is not the first transport system, the protocol layer supervising any transport system of the optical access network interrupts the synchronisation at the OLT equipment, and the ONU equipment reattempts the synchronisation with a second transport system; otherwise the synchronisation continues for the first transport system until the ONU equipment is put in communication in the optical access network.

Abstract: A method for filtering a sound signal acquired by a voice recognition system is proposed wherein the filter used to delete the unwanted sound signal is based on a noise model created from a history of preceding acquisitions of the sound signal. The method is based on the history for predicting the characteristics of the signal in the course of acquisition and relies on this prediction to establish the noise model used by the filtering function.
