摘要:
System, apparatus and method for connecting a passive optical network (“PON”) to a power line communications (“PLC”) network using a PLC HeadEnd installed at the PON to provide for distribution of high speed, broadband data communications services available on the PON to the PLC network using high speed, broadband PLC data signals. Where the PLC HeadEnd is installed on a medium voltage power distribution network, a PLC bypass unit is installed at a medium voltage/low voltage power transformer in the PLC network to provide PLC signal connectivity between the MV and LV networks. A PLC residential gateway is installed at each end user facility, such as a home or business, desiring broadband service available on the PON.
摘要:
Apparatus for coupling communication signal modulated radio frequency signals between an electrical power distribution line and the electrical power wiring at a customer's premises which includes a first transceiver for transmitting and receiving electromagnetic energy is inductively coupled to the distribution line and a second transceiver for receiving electromagnetic energy from, and transmitting electromagnetic energy to, the first transceiver. The second transceiver is coupled to the customer's power wiring to receive communication signals from, and to supply communication signals to, the customer's power wiring. The electrical power for the first transceiver can be supplied by inductive coupling to the power line and/or a battery, the battery being a back-up source when both inductive coupling and a battery are present.
摘要:
A portable, pluggable power line communications device provides convenient interfacing and connectivity between separate data networks interconnected over the same conventional electric power conveying media. The power line communications device plugs into a single electrical outlet, and includes a controller that is programmable at the device or remotely. Remote programming is achieved over the same power media to which the communications device is coupled, or by wireless link. The power line communications device controls data communications signal transfer over the common electric wiring of a local network, and conducts high-speed communications and download of multimedia signals from an upstream network controllers using the common electric power media. The data communications signals of the co-existing, different networks are encoded to permit differentiation at the power line communications device.
摘要:
A method for selecting a communication path between two nodes of a powerline network using a link quality assessment algorithm which selects a communication path based on an analysis of historical data regarding the effective throughput of data transmitted between different nodes of the network. The algorithm is also used to select an appropriate gear for such communication based on an analysis of historical data regarding the unit error rates of data transmitted between the two nodes.
