Abstract:
1. A method for reducing cross-talk in a Multiple Dwelling Unit (MDU) Home Phoneline Networking System that includes a Home Phoneline Access Multiplexer (HPAN) that services a plurality of Home Phoneline networks, the method comprising: assigning at least one time period in which the Home Phoneline stations of the Home Phoneline networks may transmit upstream communication signals to the HPAN over a plurality of communication media within a communication binder; transmitting the assigned time periods to the Home Phoneline networks; receiving the upstream communication signals from the Home Phoneline stations over the plurality of communication media within the common binder within a first assigned time period wherein the each of the Home Phoneline networks is coupled to a least one communication media of the plurality of communication media and wherein each Home Phoneline network is coupled to different communication media in relation to other Home Phoneline networks; transmitting downstream communication signals to the Home Phoneline networks over the plurality of media within the communication binder during a second time period; wherein all upstream communication signals are transmitted by the Home Phoneline stations during the first period and all downstream communication signals are transmitted to the Home Phoneline stations by the HPAN during the second period in order to reduce Near-Far cross-talk; measuring a signal strength of at least one transmission received by the HPAN from a Home Phoneline station from one of the plurality of Home Phoneline networks; determining a transmission power level for at least one Home Phoneline station of the plurality of groups of Home Phoneline networks based upon at least one measured signal strength; and transmitting the determined transmission power level to the at least one Home Phoneline station of the at least one of the plurality of Home Phoneline networks.
