20080225794 | Communication method between at least one subscriber station and at least two base stations - Communication method implementing at least one subscriber station and at least two base stations synchronised and connected to each other by a communication link. | 09-18-2008 |
20090077259 | Method and Device for Transmitting Data to Several Receivers Using Arq - The present invention concerns a method and a device for transmitting data between a sender, and at least two receivers, in a network where a data between a sender and a receiver is carried on a connection and where a unicast connection enables a sender to send the data and a receiver to acknowledge a reception of the data. The method comprises the steps of opening a unique unicast connection identified with a connection identifier; and indicating the connection identifier to the sender and the receivers, so that the sender sends the data on the unicast connection, and the receivers receive the data on the unicast connection. | 03-19-2009 |
20100122000 | Method for Accessing a Data Transmission Bus, Corresponding Device and System - 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. | 05-13-2010 |
20130115890 | METHOD FOR EVALUATING LOCATIONS OF WIRELESS ACCESS POINTS IN AN HYBRID NETWORK - A method for evaluating connectivity in an hybrid network is disclosed. The hybrid network comprising wireless access points, the method comprises step of elaborating an indirect connectivity matrix having a dimension equal to n×n, wherein an element being located at row i and line j of the indirect connectivity matrix corresponds to a direct or an indirect path between a first access point i and a second access point j. A signal sent from a first access point i to a second access j on an indirect path is successively received and re-sent by at least a third access point k. The matrix being remarkable in that the level of received signals between each access point is greater than a second level. The method further comprises a step of elaborating a direct connectivity matrix having a dimension equal to n×n, wherein an element being located at row i and line j of the direct connectivity matrix corresponds to a direct path between a first access point i and a second access point j wherein the level of received signal is greater than a first level. | 05-09-2013 |
20140064257 | METHOD OF ESTABLISHING A FIRST AND A SECOND ASSOCIATION WHICH ARE DECOUPLED - 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 VAP | 03-06-2014 |
20150098378 | METHOD FOR CONFIGURATION OF A WIRELESS NETWORK - A configuration method of a first access point of a network is disclosed which comprises a configuration the first access point as belonging to a low power set and able to transmit at a power level lower than a first value on at least one low power channel; a transmission of an indication that the first access point belongs to the low power set and a selection of a low power channel for transmission among at least one low power channel on which the reception power of a signal transmitted by the neighbouring access points is less than a second power level. | 04-09-2015 |
