  • Patent number: 12150174
    Abstract: A method and a system for transmitting data in a carrier sense multiple access wireless network wherein a plurality of data transmission devices send respectively at least one data frame at different moments from each other. Each transmission device, when it is initialised: loads the final value of a first, second and third counter, triggers the second counter as from its initial value, triggers, when the second counter has arrived at its final value, the first, triggers, when the first counter has arrived at its final value, the third counter, which is reinitialised to its initial value and retriggered whenever the presence of data is detected on the radio medium, transfers at least one data frame when the third counter has arrived at its final value.

  • Patent number: 11849373
    Abstract: A central communication unit (13), comprising: transmitter means arranged to transmit a single global downlink frame (17) addressed to all of the subscriber communication units, the global downlink frame comprising a plurality of data packets, each addressed to a respective one of the subscriber communication units, the global downlink frame supplying a common reference time so that, after receiving the global downlink frame (17), each subscriber communication unit can start transmitting an uplink frame (18) at the end of a waiting interval starting at the common reference time and having a duration equal to a respective waiting duration that is associated with said subscriber communication unit; and receiver means arranged to receive in succession the uplink frames (18) transmitted by each of the subscriber communication units.
