The present disclosure relates to communication systems and, in particular, to power delivery for communications systems.
In many information and communication technology systems, network-connected electronic devices are deployed in locations where a local electric power source is not available. With the proliferation of the Internet of Things (IoT), autonomous driving, fifth generation (5G) cellular service, and the like, it is anticipated that network-connected electronic devices will increasingly be deployed at locations that lack a conventional electric power source.
Electric power may be provided to such remote network-connected electronic devices in numerous ways. For example, a local electric utility company can install a connection to the electric power grid. This approach, however, is typically both expensive and time-consuming, and unsuitable for many applications. Composite power-data cables can also be used to power remote network-connected electronic devices and provide data connectivity thereto over a single cabling connection. Composite power-data cables refer to cables that can transmit both electric power and data. Power-over Ethernet (PoE) cables are one type of composite power-data cable. PoE technology, however, has limitations in terms of both data communication throughput and the amount of power delivered, and these limitations become more restrictive with increased distance between the remote network-connected electronic device and the PoE source. For example, under current PoE standards, high throughput data communications may only be supported for cable lengths of up to about 100 meters, and even at these short distances the power delivery capacity is only about 100 Watts. Power-plus-fiber cables are another example of a type of composite power-data cable that includes both power conductors and optical fibers within a common cable jacket. Power-plus-fiber cables, however, can be prohibitively expensive to install for many applications. Other known types of composite power-data cables include coaxial cables, telephone twisted-pair cables with remote power feeding on some pairs and Digital Subscriber Line (DSL) data on other pairs or with both power and DSL on the same pairs, and composite cables having larger conductors (e.g., 10-12 AWG) for power transmission and smaller gauge twisted pairs for data transmission.
A system that is configured to deliver electric power via an indoor telecommunications network infrastructure that is inside a building, according to some embodiments herein, may include a power adaptor that is inside the building and is electrically connected to the indoor telecommunications network infrastructure. The system may include an outdoor network interface apparatus that is outside of the building and that is configured to receive input electric power via a wired connection to the indoor telecommunications network infrastructure. Moreover, the system may include telecommunications network equipment that is outside of the building and outside of the outdoor network interface apparatus. The outdoor network interface apparatus may be further configured to provide output electric power to the telecommunications network equipment.
In some embodiments, the outdoor network interface apparatus may be further configured to receive data via the wired connection or via another wired connection to the indoor telecommunications network infrastructure.
According to some embodiments, the outdoor network interface apparatus may be an outdoor Network Interface Device (NID). Additionally or alternatively, the outdoor network interface apparatus may include power electronics circuitry that is configured to receive the input electric power via the wired connection. The wired connection may be a first wired connection, and the telecommunications network equipment may be wireless network equipment. Moreover, the power electronics circuitry may be further configured to provide the output electric power to the wireless network equipment via a second wired connection, based on the input electric power, which may be different from the output electric power. The indoor telecommunications network infrastructure may, in some embodiments, include preexisting telephone, computer-network, or coaxial wiring, or preexisting optical fiber, that is inside the building, and the wireless network equipment may be a fixed wireless node.
In some embodiments, the power adaptor may be: plugged into an electrical power outlet that is inside the building; and connected to a jack of the indoor telecommunications network infrastructure.
An outdoor network interface apparatus, according to some embodiments herein, may be configured to receive input electric power via a wired connection to an indoor telecommunications network infrastructure that is inside a building, and to provide output electric power to telecommunications network equipment that is outside of the building and outside of the outdoor network interface apparatus.
In some embodiments, the outdoor network interface apparatus may be further configured to receive data via the wired connection or via another wired connection to the indoor telecommunications network infrastructure. Additionally or alternatively, the outdoor network interface apparatus may be an outdoor Network Interface Device (NID).
According to some embodiments, the outdoor network interface apparatus may include power-conversion circuitry that is configured to: receive the input electric power via the wired connection, which may be a first wired connection; convert the input electric power into the output electric power, which may be different from the input electric power; and provide the output electric power to the telecommunications network equipment via a second wired connection.
In some embodiments, the wired connection may be a first electrical connection to a first physical communications medium of the indoor telecommunications network infrastructure. Moreover, the outdoor network interface apparatus may include a second electrical connection to a second physical communications medium of the indoor telecommunications network infrastructure. The first electrical connection may include a first cable jack, cable port, or wire terminal, and the second electrical connection may include a second cable jack, cable port, or wire terminal. Additionally or alternatively, the outdoor network interface apparatus may include power-conversion circuitry that is electrically connected to the first electrical connection, the second electrical connection, or both the first electrical connection and the second electrical connection.
According to some embodiments, the telecommunications network equipment may be wireless network equipment that is configured to provide wireless communications service into the building. Moreover, the outdoor network interface apparatus may include power electronics circuitry that is configured to provide the output electric power to the wireless network equipment based on the input electric power.
In some embodiments, the indoor telecommunications network infrastructure may include preexisting telephone, computer-network, or coaxial wiring, or preexisting optical fiber, that is inside the building and that is electrically connected to a power converter that is inside the building.
A method of delivering electric power via an indoor telecommunications network infrastructure that is inside a building, according to some embodiments herein, may include receiving input electric power at an outdoor network interface apparatus that is outside of the building via a wired connection to the indoor telecommunications network infrastructure. Moreover, the method may include providing output electric power to telecommunications network equipment that is outside of the building and outside of the outdoor network interface apparatus, based on the input electric power.
In some embodiments, the method may include receiving, via the wired connection or via another wired connection to the indoor telecommunications network infrastructure, data at the outdoor network interface apparatus. Additionally or alternatively, the method may include transmitting a signal from the outdoor network interface apparatus to the indoor telecommunications network infrastructure, to request the input electric power. Moreover, the method may include providing the input electric power to the indoor telecommunications network infrastructure via a power adaptor that is inside the building.
Pursuant to embodiments of the present inventive concepts, systems for delivering electric power and/or data via indoor telecommunications network infrastructure are provided, along with related methods and apparatuses. It may be desirable to provide electric power and/or data from inside a customer premise (e.g., a home or other building) to telecommunications (e.g., wireless) network equipment that is near, but outside of, the customer premise. It may be difficult, however, for a technician to schedule access to the inside of the customer premise, and such internal access may inconvenience the customer. Thus, to cost-effectively and time-independently (i.e., independently of the customer's schedule) install, for example, outdoor fixed wireless service or outdoor Gigabit Passive Optical Network (GPON) service at the customer premise, there should be no requirement for entrance inside the customer premise.
Embodiments of the present inventive concepts use preexisting or newly-installed indoor (i.e., internal/interior) wiring for the purpose of delivering power from the inside of the customer premise to the outside and/or facilitating data connectivity. A power adaptor (e.g., converter/transformer) may be used in a standard interior power outlet to impart power onto an indoor wiring system within local code restrictions for voltage, amperage, and wattage. Electrical connection to the indoor wiring system may be accomplished via any of various connectors. For example, RJ11 jacks or screw terminals may be used for telephone wiring, RJ45 jacks may be used for Ethernet computer-network wiring, an F-connector may be used for coaxial wiring, and so on.
Most indoor wiring systems, whether new or preexisting/abandoned, include an interface to the outside of a building. This interface is typically a Network Interface Device (NID), which may comprise an enclosure on the outside of the building. The enclosure may be a plastic enclosure, a metal enclosure, or another type of enclosure. Conventionally, the NID lacks a connection to electric power from inside the building. According to embodiments of the present inventive concepts, however, a power adaptor and associated cabling and connectors may be sent (e.g., mailed/shipped) to a customer for self-installation inside the building to serve the NID. After the customer's self-installation, a fixed wireless operator (or other telecommunications service provider) may perform an outside installation of telecommunications network equipment by electrically connecting the outdoor equipment to the NID that is served by the power adaptor, thus allowing for installation of the outdoor equipment without entry by the installer inside the building.
The delivery of electric power and/or data from inside the building to equipment that is outside of the building may be referred to as “reverse power feeding,” or simply as “reverse-feeding.” Examples of reverse power feeding over twisted-pair wiring are discussed in the technical specification ETSI TS 101 548-1 V2.2.1 (2018-06), which is incorporated herein in its entirety by reference. The ETSI technical specification discusses, for example, power insertion at a customer premise and power extraction by a remote node. Moreover, data communication can be performed using, for example, G.fast transmission (ITU-T G.9700 & G.9701) over one twisted-pair or over coaxial wiring. As another example, Gigabit Ethernet can be combined with PoE on a Category 5 or Category 6 cable.
Embodiments of the present inventive concepts can reverse-feed electric power from the building to, for example, an access point that is used by a television provider (or other telecommunications service provider) outside of the building. Moreover, this reverse power feeding may be performed even if the network infrastructure (e.g., wiring) that is used inside the building for the reverse-feeding is not abandoned (i.e., is used for its original intended telecommunications purpose). In some embodiments, if the network infrastructure is abandoned, then it may be used to reverse-feed both (a) electric power and (b) data to the access point.
Example embodiments of the present inventive concepts will be described in greater detail with reference to the attached figures.
To reduce costs and increase the speed at which electric power and data connectivity can be deployed to remote network-connected powered devices such as the remote devices 130, 140, 150, 160, 170, 180 illustrated in
One drawback of the approach disclosed in PCT Publication No. WO 2018/017544 A1 is that as new installations are deployed, it is necessary to install another power-plus-fiber cable that runs from the power source to the new installation. Deploying such power-plus-fiber cables can be time consuming and expensive, particularly in urban environments.
According to U.S. Patent Application No. 62/700,350, which is incorporated herein in its entirety by reference, the power source equipment and remote distribution node approach disclosed in PCT Publication No. WO 2018/017544 A1 may be extended so that cellular network operators may create a hard wired power and data connectivity micro grid throughout high density urban and suburban areas. As new installations (e.g., new small cell base stations 130, security cameras 180, and the like) are deployed in such areas, the cellular network operator may simply tap into a nearby portion of the micro grid to obtain power and data connectivity without any need to run cabling connections all the way from the power and data source equipment to the new installation. The micro grids may be viewed as being akin to the backplane on a computer, as the micro grids extend throughout the area in which power and data connectivity are required and have excess power and data connectivity resources available so that new installations may simply “plug into” the micro grid at any of a large number of tap points.
The interior region 201 is separated from the outdoor NIA 220 by an exterior surface 203 of the building 102. The exterior surface 203 comprises one or more materials exposed to outdoor elements, including materials such as brick, stone, concrete, stucco, vinyl siding, wood siding, and/or glass. The term “outdoor,” as used herein, refers to an apparatus that is not inside the building 102. For example, the outdoor NIA 220 may be on or adjacent the exterior surface 203.
In some embodiments, the outdoor NIA 220 may be electrically connected to outdoor telecommunications network equipment 230 (e.g., outdoor wireless network equipment 230W), which may comprise one or more of the remote devices 130, 140, 150, 160, 170, 180 (
Inside the building 102, the indoor infrastructure 215 comprises one or more physical communications media 216 (
In some embodiments, a power adaptor 210 is also inside the building 102 and is electrically connected to the indoor infrastructure 215. In particular, the power adaptor 210 may be configured to provide (e.g., insert) electric power to the indoor infrastructure 215. This enables the outdoor NIA 220, which is electrically connected to the indoor infrastructure 215, to deliver electric power to the outdoor equipment 230, which may otherwise lack a power source.
The power adaptor 210 may provide electric power when it is plugged into an electrical power outlet 205 of the building 102. For example, the outlet 205 may be in the same room inside the building 102 as an outlet for the indoor infrastructure 215. The power adaptor 210 may thus have both a wired electrical connection 207 to the outlet 205 and a wired electrical connection to the indoor infrastructure 215. For example, the power adaptor 210 may comprise one or more connectors, such as cable jacks, cable ports, or wire terminals, for the indoor infrastructure 215.
The power adaptor 210 may comprise power-conversion circuitry/equipment and/or power-insertion circuitry/equipment. In some embodiments, the power adaptor 210 may further comprise data-extraction-and-insertion circuitry/equipment that is configured to transmit and receive data via the indoor infrastructure 215. Alternatively, a separate adaptor inside the building 102 may comprise the data-extraction-and-insertion circuitry/equipment. Accordingly, the system 200 may comprise the power adaptor 210, a data adaptor, the indoor infrastructure 215, the outdoor NIA 220, the wired connection 225, and/or the outdoor equipment 230.
For example, the connection(s) 217 may include a first electrical connection 217-A and a second electrical connection 217-B, each of which may comprise one or more connectors, such as cable jacks, cable ports, or wire terminals, for the indoor infrastructure 215 (
Moreover, the connection 218 may comprise a connector, such as a power-cord port and/or a coaxial connector, for the wired connection 225 (
Though
In some embodiments, the outdoor NIA 220 may be, or may be included in, an outdoor NID 220D, which is sometimes also referred to in the telecommunications industry as a “network interface unit,” a “telephone network interface,” a “system network interface,” a “telephone network box,” or a “network termination device.” The outdoor NID 220D provides demarcation between (a) a telecommunications carrier's wiring and equipment and (b) a telecommunications customer's wiring and equipment. For example, the outdoor NID 220D may comprise a small, weather-resistant box that is mounted on the outside of the customer's building 102 (
A portion of the first medium 216-A may extend from inside the building 102 (
In some embodiments, the indoor infrastructure 215 may be inside one or more walls and/or ceilings 202 of the building 102. Moreover, the first medium 216-A and/or the second medium 216-B may be installed inside the building 102 before the power adaptor 210 (
In some embodiments, the outdoor NIA 220 may be attached (e.g., mounted with screws or other fasteners) to an exterior surface 203 of the building 102 (
In some embodiments, the outdoor NIA 220 may also receive (Block 420) data via the wired connection 217 or via another wired connection 217 to the indoor infrastructure 215. For example, the operations of Block 420 may include concurrently or sequentially receiving data and electric power via the same wired connection 217, or via different respective wired connections 217.
Additionally or alternatively, the outdoor NIA 220 may transmit (Block 410) a signal to the indoor infrastructure 215. For example, the outdoor NIA 220 may transmit, via the indoor infrastructure 215, a request/command for data and/or electric power to a power adaptor 210 (
Referring to
As shown in
For example, the processor 550 and the memory 570 may control the power electronics circuitry 227 to perform one or more of the operations shown in
Systems, methods, and apparatuses for delivering electric power and/or data via indoor telecommunications network infrastructure 215 according to embodiments of the present inventive concepts may provide a number of advantages. As an example, the system 200 illustrated in
The outdoor NIA 220 may include power electronics circuitry 227 (
The power electronics circuitry 227 may be an original component of the outdoor NIA 220 or may be a retrofit component (e.g., a box/module) that is added to the outdoor NIA 220. Moreover, the power electronics circuitry 227 may be configured to convert/deliver only electric power or to transmit/receive data in addition to converting/delivering electric power.
Accordingly, whereas a conventional NID on a building provides telephony access but typically lacks electric power from inside the building, embodiments of the present inventive concepts may allow a customer to self-install a device, such as a power adaptor 210 (
For example, the power adaptor 210 can (i) take power from an indoor power grid of the building 102, (ii) perform a power conversion on the power from the indoor grid, and then (iii) insert the converted power onto a telephone cable that extends from the power adaptor 210 and connects (e.g., via a telephone wall jack) to an indoor telephone wiring network. The inserted power is delivered over that network to the outdoor NIA 220. Additionally or alternatively, the power adaptor 210 can be coupled to an indoor coaxial network via a coaxial cable that connects to a coaxial wall jack. Accordingly, the power adaptor 210 can deliver power to the outdoor NIA 220 via, for example, an indoor telephone wiring network and/or an indoor coaxial network. Embodiments of the present inventive concepts can thus advantageously facilitate cost-effective and time-independent installation of communications equipment/service (e.g., fixed wireless service provided by a fixed wireless node 150 (
The present inventive concepts have been described above with reference to the accompanying drawings. The present inventive concepts are not limited to the illustrated embodiments. Rather, these embodiments are intended to fully and completely disclose the present inventive concepts to those skilled in this art. In the drawings, like numbers refer to like elements throughout. Thicknesses and dimensions of some components may be exaggerated for clarity.
Spatially relative terms, such as “under,” “below,” “lower,” “over,” “upper,” “top,” “bottom,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the example term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Herein, the terms “attached,” “connected,” “interconnected,” “contacting,” “mounted,” and the like can mean either direct or indirect attachment or contact between elements, unless stated otherwise.
Well-known functions or constructions may not be described in detail for brevity and/or clarity. As used herein the expression “and/or” includes any and all combinations of one or more of the associated listed items.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present inventive concepts. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “comprising,” “includes,” and/or “including” when used in this specification, specify the presence of stated features, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, operations, elements, components, and/or groups thereof.
