  • Managing coexistence on a shared power line medium
    Patent number: 8913629
    Abstract: Within a domain of a master device, devices that share a power line as a communications medium monitor signal detection windows to sense network status. The devices transmit sensed network status to the master device. The master device allocates channel resources based on the network statuses communicated by the devices within the domain.

  • Method for transmitting data by means of a carrier current
    Patent number: 7746763
    Abstract: The invention relates to a method for transmitting data over a carrier current using a frequency band. According to said method: the frequency band is divided into N sub-bands, N being a whole number higher than, or equal to, two; an OFDM (Orthogonal Frequency Division Multiplexing) technique is carried out on each of said sub-bands; and calculations are carried out based on each sub-band. The inventive method is characterised in that the calculations based on each sub-band are independent from the calculations based on the other sub-bands, and said sub-bands are dynamically activated and allocated. The invention also relates to modulation and demodulation devices for carrying out said method.
