  • Patent number: 11700576
    Abstract: A method for reactivating a wireless communication network in accordance with one of the IEEE 802.11 standards is described. The communication network includes a plurality of gathering nodes, each gathering node includes at least one access-point and/or user radio-frequency interface and/or a user of a so-called backhaul wireless network associated with the communication network, which are deactivated in sending mode, A beacon frame sent by a master node of the reactivation method is propagated gradually in order to reactivate all the nodes in the network.
    Type: Grant
    Filed: October 6, 2020
    Date of Patent: July 11, 2023

  • Patent number: 10820186
    Abstract: To assist roaming of a mobile terminal from a first wireless LAN to a second wireless LAN respectively managed by first and second access points, the first access point (AP) makes measurements of communication quality with the mobile terminal and/or of operational load. By comparing the measurements with thresholds, the first AP can trigger a selection procedure assisted by a server or trigger an autonomous selection procedure, at the end of which the first AP transmits to the mobile terminal a weighted list of access points that are candidates for the roaming. In the assisted selection procedure, the first AP, in constructing the weighted list, takes into account instantaneous measurements of operational load on the candidate access points supplied by the server, and, in the autonomous selection procedure, the first AP, in constructing the weighted list, takes into account long-term statistics of operational load on the candidate access points.

  • Publication number: 20190200412
    Abstract: A management device equips a communicating apparatus including at least one radio interface and at least one physical interface. This device includes its own analyzing system, in the event that a peripheral is connected to the physical interface, to determine a mapping of the quality of radio communications on this radio interface, and a processor suitable for comparing this determined mapping to another mapping of the quality of radio communications on the radio interface in the absence of a peripheral connected to the physical interface, and, in the event of a deterioration in the quality of radio communications as a result of this connection, to trigger a modification of a first current operating configuration of the radio interface based on the determined mapping or a second current operating configuration of the physical interface.
