Abstract: A method for establishing a first and second association between a main node and respectively a first and second wireless node is disclosed. The first association associates a first virtual access point VAP1 of the main node and the first node. The first virtual access point transmits to the first node first beacon frames comprising a first item of information BSSID1 representative of the first association BSS1. The first virtual access point VAP1 is identified by a services set identifier SSID. According to the invention, when the main node receives from the node a request for the establishment of the second association BSS2, the method comprises, at controller level, a step of creation of a second virtual access point so as to isolate the transmissions over the associations.

Abstract: The present invention concerns a data transfer system for transferring data signals between a system input and a system output, and associated products. The system comprises a first data consuming set, receiving the data signals (SGNL1) from the system input, writing them therein and reading them for sending them towards a second data consuming set, the second set receiving the data signals (SGNL0), writing them therein and reading them for sending them (SGNL2) to the system output, and transfer means transferring the data signals from the first to the second data consuming set. The first set incorporates within the data signals to be transmitted, read requests (rd_req1) for reading the data signals from the first data consuming set. The transfer means carry those read requests with the data signals, and the second set receives them for synchronization between the first and second sets.

Abstract: The invention relates to a bus, which is connectable to a primary master and to secondary masters, the bus being suitable for the transmission of data between the peripherals. In order to ensure a minimum rate and/or maximum latency between the secondary masters, when the primary master uses a small time fraction available on the bus, said primary master is provided with the highest priority and comprises means for wirelessly accessing to a medium. The inventive method for accessing to the bus consists in authorising the primary master to access to the bus upon the request thereof and in selecting the access to the bus for the secondary masters when the primary master peripheral does not request said access to the bus.

Abstract: Method of adjustment of a receiver of signals transmitted in bursts in a system where the communications are set up within the context of successive frames comprising slots allocatable to the transmitters for their communications with the receivers. The adjustment of at least one characteristic of the receiver allows it to adapt upon the arrival of the bursts, by taking account of at least one reinitialization parameter for a first burst or adjustment parameter computed by a computation unit (4) from the preamble of the burst currently being received. At least one specified adjustment parameter is determined by a computation unit (4), for a new burst of a communication, by taking into account the part of the signal corresponding to the payload of the burst previously received for this communication, if the new is separated from this previously received burst only by a time which is less than a silence threshold value.
