A powerline communications device comprises a powerline communications interface and at least one other communications interface configured to communicate over a computing network. The powerline communications interface is further configured to receive electrical power. The computing network may comprise mediums including powerlines, telephone lines, and / or coaxial cables. In some embodiments, the powerline communications interface may communicate with a network apparatus, such as a personal computer, via an Ethernet interface. The powerline interface, the telephone line interface, and / or the coaxial cable interface may all be associated with the same media access control (MAC) address. The powerline communications device may receive a message via a first medium and repeat the message via a second medium based on a quality of service (QoS) metric. In some embodiments, the powerline communications device may communicate using multiple frequency bands.

A home appliance network system and a method for operating the same, wherein a network master can not only automatically generate a unique house address of a corresponding home, but also sense a network collision of the corresponding home with a neighboring home to maintain house address uniqueness. The network master manages / controls one or more home appliances connected to a network of the corresponding home and determines whether the generated house address collides with that of the neighboring home. If the generated house address is determined to collide with that of the neighboring home, the network master automatically changes the house address to a new one to maintain house address uniqueness. As a result, the network master can prevent a network interference / collision with the neighboring home, thereby increasing security and stability of the home appliance network system at low cost.

An alternating current power strip 1 with network repeating and management 23 functionality is hereby disclosed.

An electric power line communication system operates with an electric power distribution system to provide through premises power distribution lines highly reliable communication links among power line communication devices electrically coupled or located in proximity to the premises power distribution lines. Each power line communication device associated with a set of premises power distribution lines has an identification address. A master code identifies the power line communication devices as members of a system domain of power line communication devices associated with the set of premises power distribution lines. Association of the master code with the identification addresses renders the member power line communication devices capable of operation without unintended communication with power line communication devices associated with a separate, different set of premises power distribution lines.

In conjunction with a wiring in a house carrying data network signal, a modular outlet comprising of a base module and interface module. The base module connects to the wiring and attached to a wall. The interface module provides a data unit connection. The interface module is mechanically attached to the base module and electrically connected thereto. The wiring may also carry basic service signal such as telephone, electrical power and cable television (CATV). In such a case, the outlet will provide the relevant connectivity either as part of the base module or as part of the interface module. Both proprietary and industry standard interfaces can be used to interconnect the module. Furthermore, a standard computer expansion card (such as PCI, PCMCIA and alike) may be used as interface module.

A remote control method for controlling electrical appliance via a home gateway proceeds with an input signal by a telephone call to initiate the main board (the host) to connect to the INTERNET. After registering to the specific DNS server to have the pre-registered IP address, the user is able to control the initiation of household electrical appliances.

A data transceiving station of digital data frames includes a digital modem coupled to a transmission line, and a microprocessor receiving demodulated data from the modem according to a Packet Mode or a Bit Mode transmission through an interface circuit. The interface circuit switches between the Packet Mode and the Bit Mode transmission during transfer of a data frame to the microprocessor. The data transceiving station combines the superior speed of a Packet Mode transfer with the unlimited compatibility of a Bit Mode transfer.

Power supply current, sufficient to power a remote network device, is transmitted concurrently with a network data signal over a transmission line. A power-sourcing network device that can include a coupling circuit provides power and data to the remote network device. The remote network device (which can be a wireless access point) can separate the power signal from the data signal and use the power supply current to further process or retransmit the data signal. The power signal may be a low frequency relative to the frequency of the data signal, or it may be DC.

An apparatus for converting a low voltage alternating current (AC) wiring circuit to a high speed data communications link, comprising a primary coupling circuit and a secondary coupling circuit. The apparatus provides low voltage AC power to a data device and couples data signals between the data device and the AC power line via the converted low voltage AC wiring circuit. An example is provided for retrofitting a door chime system to a high speed data link such as a video camera system.

A method for communication over a network of power lines (34), including establishing a communication link within a selected frequency band over the network between a first transceiver (32B) coupled to the network and a second transceiver (32C) coupled to the network. The method further includes transmitting a first signal over the link from the first transceiver to the second transceiver at a transmission power level that is sufficiently strong that the signal can be decoded by the second transceiver, but is attenuated sufficiently when it reaches a third transceiver (32E) coupled to the network so that the third transceiver can receive a second signal over the network in the selected frequency band substantially without interference by the first signal.

A serial intelligent cell (SIC) and a connection topology for local area networks using Electrically-conducting media. A local area network can be configured from a plurality of SIC's interconnected so that all communications between two adjacent SIC's is both point-to-point and bidirectional. Each SIC can be connected to one or more other SIC's to allow redundant communication paths. Communications in different areas of a SIC network are independent of one another, so that, unlike current bus topology and star topology, there is no fundamental limit on the size or extent of a SIC network. Each SIC can optionally be connected to one or more data terminals, computers, telephones, sensors, actuators, etc., to facilitate interconnectivity among such devices. Networks according to the present invention can be configured for a variety of applications, including a local telephone system, remote computer bus extender, multiplexers, PABX / PBX functionality, security systems, and local broadcasting services. The network can use dedicated wiring, as well as existing wiring as the in-house telephone or electrical wiring.
