Definitions
- the present invention relates to powerline communications and in particular, powerline communication devices, and systems of use therefore.
- PLC Powerline communication
- PLC is a technology that encodes data in a signal and transmits the signal on existing electricity powerlines in a band of frequencies that are not used for supplying electricity. Accordingly, PLC leverages the ubiquity of existing electricity networks to provide extensive network coverage. Furthermore, since PLC enables data to be accessed from conventional power-outlets, no new wiring needs to be installed in a building (or different parts of a building). Accordingly, PLC offers the additional advantage of reduced installation costs.

Abstract
Description
- This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Ser. No. 61/503,060 filed Jun. 30, 2011, which is incorporated herein by reference in its entirety.
- 1. Field of the Invention
- The present invention relates to powerline communications and in particular, powerline communication devices, and systems of use therefore.
- 2. Description of the Related Art
- With the growing need for the exchange of digital content (e.g. MP3 audio, MPEG4 video and digital photographs) there is a widely recognized need to improve digital communication systems. Powerline communication (PLC) is a technology that encodes data in a signal and transmits the signal on existing electricity powerlines in a band of frequencies that are not used for supplying electricity. Accordingly, PLC leverages the ubiquity of existing electricity networks to provide extensive network coverage. Furthermore, since PLC enables data to be accessed from conventional power-outlets, no new wiring needs to be installed in a building (or different parts of a building). Accordingly, PLC offers the additional advantage of reduced installation costs.
- Communications within a household or within other premises may also be serviced by a Wireless Local Area Network (WLAN), a cellular network, millimeter wave communications, e.g., 60 GHz, Wireless Personal Area Network (WPAN), Cable Modem Network, Local Area Network (LAN), and other communication techniques. Each of these communication types has its respective benefits and shortcomings. None of these communication types is typically able to provide a full coverage solution within the household (or other premises). The shortcoming of all wired technologies is the lack of mobility thereof. Shortcomings of all wireless technologies are coverage holes, which are typical, interference from other wireless devices, including competing wireless devices, Radar, etc., and bandwidth limitations.

FIG. 1 is a system diagram illustrating a premises in which at least one Powerline Communication (PLC) device resides that operates according to one or more embodiments of the present invention. Thepremises 100 has a distributed mains wiring system (not shown) consisting of one or more ring mains, several stubs and some distribution back to a junction box. In other constructs the distributed mains wiring system has a breaker box with circuits routed there from in a star configuration. For the sake of example, thepremises 100 has fourareas room household 100. In particular, the outlets most closely located to each other are those on multi-plug strips, and the outlets furthest away from each other are those on the ends of stubs of different ring mains (e.g. power outlets in the garden shed and the attic). The majority of outlets associated with a particular application (e.g. Home Cinema) are normally located relatively close together. - Installed within the
premises 100 are a plurality ofPLC devices FIG. 2 and/orFIG. 4 and that operates according to the operations described with reference toFIGS. 5-7 . One or more of these PLC devices 110-122 may be a power adapter PLC I/F that services a coupled mobile communication device, e.g.,laptop computer mobile handset - According to a first aspect of the present invention, a mobile communication device, e.g., 136, 138, 140, and/or 142 establishes a wireless communication link with at least one wirelessly coupled device to service a communication session via its wireless interface. This wireless communication link may be one or more of a Wireless Local Area Network (WLAN) communication link, a cellular communication link, a Wireless Wide Area Network (WWAN) communication, or a Millimeter Wave (MMW) communication link. This communication link may be serviced by a WLAN access point located in the premises or external to the premises (not shown) or a MMW access point located within one of the
spaces premises 100. - In its operation, upon being direct or indirectly coupled to the power mains, the mobile communications device detects availability of a PLC communication path via a wired interface. Then, the mobile communications device at least partially hands over the communication session from the wireless interface to the wired interface.
- In a first embodiment, the mobile communications device couples to a power converter/PLC interface provided by the
premises 100 owner/operator. This power converter/PLC interface may be a USB plug, fire wire plug, or another type of plug that supports both charging and communications and may serve as any or more of the PLC devices 110-122 ofFIG. 1 . Alternately, the mobile communications device has the power converter/PLC interface included so that a user of the mobile communications device simply plugs in the mobile communications device to a plug in thepremises 100. In any case, by itself or via a coupled PLC interface, the mobile communication device may support communications according to a plurality of PLC communication standards. In such case, the mobile communications device may communicate with any of the PLC devices 110-122 of thepremises 100 or devices outside of the premises that are accessible via the power mains. - In a first operation, at least partially handing over the communication session from the wireless interface to the wired interface includes terminating the wireless communication and servicing the communication session via the wired communication interface and the PLC communication path. In a second operation, at least partially handing over the communication session from the wireless interface to the wired interface includes servicing a first portion of the communication session via the wireless communication interface and servicing a second portion of the communication session via the wired communication interface and the PLC communication path.
- In determining whether to fully or partially handover the communication session, the mobile communications device may consider data throughput requirements, available data throughput via the wireless link, available data throughput via the wired link (and PLC backbone), cost of each link, and other considerations. For example, a wireless cellular link may charge on the basis of usage with the PLC backbone communications being free. In this case, the communication session would be handed over to reduce cost. In another example, the mobile communications device is servicing a voice call and call quality suffers due to link quality. In this case, the communication session would be handed over to the PLC backbone based upon service quality. In still another operation, some portions of the communication session would be handed over to the PLC backbone while others would continue to be serviced via the wireless link.

wireless device 300 is operable to support the operations described further with reference toFIGS. 5-7 . - The wired I/
F 316 may support USB communications, Firewire communications, other serial communications and/or parallel communications. A power converter/PLC I/F 318 is shown to be external to the portableelectronic device 300.

FIG. 4 is a block diagram illustrating a power converter/PLC I/F including at least part of a communication interface that operates according to one or more embodiments of the present invention. The power converter/PLC I/F 318 is made up of three main elements, an AC toDC module 400,signal coupling circuitry 402 and zerocrossing circuitry 404. While power converter/PLC I/F 318 can be integral with a device, according to the embodiment ofFIGS. 2 and/or 3, power converter/PLC I/F 318 is often external to, and/or detachable from, an device, e.g., personal computer, router, laptop computer, tablet computer, cell phone, etc. The device for which the power converter/PLC I/F 318 is designed may include a wired interface configured to send and receive digitally encoded signals consistent with one or more PLC communication standards, and other wired communication standards. Such wired interface typically includes data transmission (TX) circuits for transmitting digitally encoded signals, and data reception (RX) circuits for receiving digitally encoded signals, as is known in the art. Such a device can also include at least some of the active and/or passive components of a communication interface. - The AC to
DC module 400 is configured to convert the AC line voltage of a power main 406 to one or more DC voltages (e.g., +/−5 v, +/−9 v, +/−12 v, or the like) on one ormore conductors 408. The power converter/PLC I/F 318 may also include anoptional filter 410 in electrical communication between AC toDC module 400 and thepower line 406, or between AC toDC module 318 andsignal coupling circuitry 408. Thefilter 410 is configured to protect other components of power converter/PLC I/F 318 from electrical noise generated by AC toDC module 400.Filter 410 can be a low-pass filter, for example. Thefilter 410 can also couple anexternal AC socket 412 to thepower line 406 in some embodiments. Thefilter 410 can then also serve to remove noise generated by any devices attached toAC socket 412. A further filter may also be provided on the output side of the AC toDC module 400. - As noted, power converter/PLC I/
F 318 also includessignal coupling circuitry 402 in electrical communication withpower line 406 and configured to send and receive digitally encoded signals over one ormore conductors 414.Signal coupling circuitry 402 includes atransformer 416 and can optionally also include one or more of, all of, any combination of, or part(s) of:coupling capacitor 418,signal conditioner 420, anover-voltage protection device 422, and afuse 424.Signal coupling circuitry 402 may include an entire communication interface or merely a part thereof with the remaining part of the communication interface optionally residing in the device attached thereto. - Zero
crossing circuitry 404 may include, for example, a LED (light-emitting diode) and an adjacent photo detector (neither shown). In the zerocrossing circuitry 404, the LED is in electrical communication withpower line 406 and is configured to emit light pulses that are synchronized to the waveform of the AC line voltage. Photo detector receives the light pulses and produces a timing signal that can be communicated over one ormore conductors 426 to a coupled device. - Power converter/PLC I/
F 318 is connected to the communication device by cabling, which supports communications between the device and the power converter/PLC I/F 318. Cabling may be integral with power converter/PLC I/F 318. The cabling may include one or more conductors 408 (typically two) configured to convey the one or more DC voltages between power converter/PLC I/F 318 and the device, one or more conductors 414 (typically two) configured to convey the digitally encoded signals between an device and power converter/PLC I/F 318 and one or more conductors (typically two) for communicating the timing signal from the zero-crossingcircuitry 404. Therefore there are typically six output conductors from the AC/DC converter. Where the power converter/PLC I/F 318 is detachable from an device, theconductors Conductors 414 are optionally rated for the digitally encoded signals but not rated for voltages as high as the AC voltages found on the power line. -
FIG. 5 is a flowchart illustrating operation according to one or more embodiments of the present invention.Operations 500 ofFIG. 5 are performed by a mobile communication device, such as one of themobile communication devices FIG. 1 .

This communication session may be serviced according to one or more of WLAN communications, cellular communication, WWAN communications or MMW communications.Operations 500 continue with the mobile communication device servicing the communication session using its wireless interface (Step 504). - Next,
operation 500 includes the mobile communication device detecting the availability of PLC communications via the device's wired interface or PLC I/F (Step 504). In some embodiments, detecting the availability may be based upon a user of the mobile communication device plugging the device into a power plug within a premises having PLC support. In other operations, the mobile communication device may learn of the PLC availability via a WLAN broadcast. - Operation continues with the mobile communication device establishing a communication path that includes a PLC communication path via its wired interface (Step 508). Such PLC communication path may be serviced by a built in PLC interface or via an external power adapter/PLC I/F such as 318 illustrated in
FIGS. 2 and 3 , via USB connector, for example.

This division may be based upon the relative costs of the communications via the wired and wireless interfaces, the available data throughput available via these interfaces, or upon other factors. Then, operation includes servicing a first portion of the communication session via the wireless communication interface (Step 704) and servicing a second portion of the communication session via the wired communication interface and the PLC communication path (Step 706). -
FIG. 8 is a block diagram illustrating the construct of another power converter/PLC I/F that operates according to one or more embodiments of the present invention. The PLC I/F 800 ofFIG. 8 includes a plurality of components that may be housed in a single device or a combination of devices. The PLC I/F 800 supports both charging and communication operations. The PLC I/F 800 couples to a power main and also includes apower plug 811 to allow another devices to plug into. AC power is drawn from the power mains and is filtered by transformer and electromagnetic interference (EMI)components 813 that down convert the AC voltage to a lower voltage level than that carried by the power mains and provide EMI isolation between the additional components of the PLC I/F 800 and the power plug/power mains. - The PLC I/
F 800 further includesrectification components 815 to rectify the AC voltage at the lower level to a rectified AC voltage at the lower voltage level. The output of therectification components 815 is processed by a power stage (adaptive voltage)component 817 that produces an output voltage at DC. Afilter 819 filters the output of thepower stage component 817 to provide a DC voltage output topower switch components 821. Feedback andcontrol components 823 sense the output of thefilter 819 and the rectified AC voltage and provide a control signal to thepower stage component 817, directing thepower stage component 817. - The
power switch components 821 couple to a plurality ofconnectors connector 825 couples to an Ethernet plug that provides Power over Ethernet (PoE) communication/power service. Further,connector 827 couples to a USB connector that also supports both communications and power service.Connector 829 is simply a power plug that provides DC power to a coupled personal computer, for example. Thepower switch components 821 also supports a bypass AC to selected AC tap connection to provide AC power viaconnector 831. The selected AC tap can be a full bypass of the AC power incoming via theconnector 831. Alternatively, the AC can be particularly selected via a down-conversion process performed by thecomponents 813 to fit a lower voltage AC needs via theconnector 831. Thepower switch components 821 provide a switch fabric to provide the various AC and DC voltages to the coupled connectors. - The PLC I/
F 800 further includes a plurality of communications and control components, which support PLC communications and other communications. These components include PLC Tx/Rx andrelated components 833 that couple and decouple PLC communications to the power mains. Further components include single or simultaneous Tx/Rx path switching, bridging, andcontrol component 835 that interfaces the PLC Tx/Rx andrelated components 833 to one or morewireless interfaces control component 835 bridges communications via the various communication interfaces of the PLC I/F 800. In particular,control components 845, based uponcontrol feedback 843, in some operations, control the flow of communication signals within the PLC I/F 800. In their various operations these components may bridge PLC/wireless, PLC/Ethernet, PLC/USB, USB/wireless, Ethernet/Wireless, USB/Ethernet, or bridging between any two types of supported communications. - For each of the
connectors power switch components 821. In addition, such connectors and associated cabling may act as communication pathways as well. Communication exchanges flowing between each of the connectors and theAC connector 811 is managed via the bridging andcontrol 835. That is, any signal originating from any one of theconnectors control component 835. - The
control feedback 843 may also serve to provide feedback for voltage level. For example, the powered devices coupled viaconnectors control components 845. Thecontrol components 845 may then control the power switch components via thecontrol feedback 843 to adjust DC voltage levels provided to the connectors. -

Further note that if the processing module, module, processing circuit, and/or processing unit implements one or more of its functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the memory and/or memory element storing the corresponding operational instructions may be embedded within, or external to, the circuitry including the state machine, analog circuitry, digital circuitry, and/or logic circuitry. Still further note that, the memory element may store, and the processing module, module, processing circuit, and/or processing unit executes, hard coded and/or operational instructions corresponding to at least some of the steps and/or functions illustrated in one or more of the FIGs. Such a memory device or memory element can be included in an article of manufacture.
- The present invention has been described above with the aid of method steps illustrating the performance of specified functions and relationships thereof. The boundaries and sequence of these functional building blocks and method steps have been arbitrarily defined herein for convenience of description. Alternate boundaries and sequences can be defined so long as the specified functions and relationships are appropriately performed. Any such alternate boundaries or sequences are thus within the scope and spirit of the claimed invention. Further, the boundaries of these functional building blocks have been arbitrarily defined for convenience of description. Alternate boundaries could be defined as long as the certain significant functions are appropriately performed. Similarly, flow diagram blocks may also have been arbitrarily defined herein to illustrate certain significant functionality. To the extent used, the flow diagram block boundaries and sequence could have been defined otherwise and still perform the certain significant functionality. Such alternate definitions of both functional building blocks and flow diagram blocks and sequences are thus within the scope and spirit of the claimed invention. One of average skill in the art will also recognize that the functional building blocks, and other illustrative blocks, modules and components herein, can be implemented as illustrated or by discrete components, application specific integrated circuits, processors executing appropriate software and the like or any combination thereof.
- The present invention may have also been described, at least in part, in terms of one or more embodiments. An embodiment of the present invention is used herein to illustrate the present invention, an aspect thereof, a feature thereof, a concept thereof, and/or an example thereof. A physical embodiment of an apparatus, an article of manufacture, a machine, and/or of a process that embodies the present invention may include one or more of the aspects, features, concepts, examples, etc. described with reference to one or more of the embodiments discussed herein. Further, from figure to figure, the embodiments may incorporate the same or similarly named functions, steps, modules, etc. that may use the same or different reference numbers and, as such, the functions, steps, modules, etc. may be the same or similar functions, steps, modules, etc. or different ones.
- Unless specifically stated to the contra, signals to, from, and/or between elements in a figure of any of the figures presented herein may be analog or digital, continuous time or discrete time, and single-ended or differential. For instance, if a signal path is shown as a single-ended path, it also represents a differential signal path. Similarly, if a signal path is shown as a differential path, it also represents a single-ended signal path. While one or more particular architectures are described herein, other architectures can likewise be implemented that use one or more data buses not expressly shown, direct connectivity between elements, and/or indirect coupling between other elements as recognized by one of average skill in the art.
- The term “module” is used in the description of the various embodiments of the present invention. A module includes a processing module, a functional block, hardware, and/or software stored on memory for performing one or more functions as may be described herein. Note that, if the module is implemented via hardware, the hardware may operate independently and/or in conjunction software and/or firmware. As used herein, a module may contain one or more sub-modules, each of which may be one or more modules.
- While particular combinations of various functions and features of the present invention have been expressly described herein, other combinations of these features and functions are likewise possible. The present invention is not limited by the particular examples disclosed herein and expressly incorporates these other combinations.
- The present invention has also been described above with the aid of method steps illustrating the performance of specified functions and relationships thereof. The boundaries and sequence of these functional building blocks and method steps have been arbitrarily defined herein for convenience of description. Alternate boundaries and sequences can be defined so long as the specified functions and relationships are appropriately performed. Any such alternate boundaries or sequences are thus within the scope and spirit of the invention.
- Moreover, although described in detail for purposes of clarity and understanding by way of the aforementioned embodiments, the present invention is not limited to such embodiments. It will be obvious to one of average skill in the art that various changes and modifications may be practiced within the spirit and scope of the invention.
