DETAILED DESCRIPTION

[0012] For simplicity and illustrative purposes, the principles of the embodiments are described by referring mainly to examples thereof. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. It will be apparent however, to one of ordinary skill in the art, that the embodiments may be practiced without limitation to these specific details. In some instances, well known methods and structures have not been described in detail so as not to unnecessarily obscure the embodiments.

[0013] The term Wi-Fi refers to a technology for wireless local area networking of electronic devices, for instance, as based on IEEE 802.11 standards, 802.11 is an evolving family of specifications for wireless local area networks (WLANs) developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). These standards, for instance, define various frame types that stations (network interface cards and access points) used for communications, as well as for managing and controlling wireless links. A Wi-Fi network, such as a wireless local area network (WLAN) may be provided at a home, residence facility, business, or the like customer premises for providing Wi-Fi service to various wireless electronic client devices of the customer at a customer premises.

[0014] Broadband access may be provided to the customer premises by connecting the WLAN at the customer premises to an external network, such as an access network, a service provider's network, a wide area network, the Internet, or the like.

[0015] Typically, the so-called last meter of broadband access provided to the customer premises is provided by drilling holes through walls or roofs of a building and extending cables, wires, or the like therethrough during an installation process. For instance, such installations at the home 10 shown in FIG. 1 may be provided at a wall mount location 12 (i.e., for connection to a cable or optical network) or a roof mount location 14 (i.e., for connection to a satellite dish or cellular mobile network). One or more holes would be drilled through the building at these locations to attach CPE to walls or roofs and to permit data and/or power wires, cables and the like to be extending into an interior of the building from an exterior of the building.

[0016] In accordance to an embodiment, wireless connectivity and power are used in the last meter of broadband access and thereby eliminate conventional requirements of drilling holes or channels through walls or roofs of buildings through which wires or cables are extended. The wireless connectivity is accomplished by optical communication technology and the wireless powering of CPE is accomplished by wireless charging technology.

[0017] Thus, according to an embodiment, the so-called last meter of broadband access is provided to a customer premises through glass or like material through which light may pass. For instance, such material may be provided by a window or the like of a building. For example, as shown in FIG. 2, broadband access may be provided to the customer premises by connecting the WLAN at the customer premises to an external network, such as an access network, a service provider's network, a wide area network, the Internet. or the like via an installation at the home 10 at a window mount location 16 (i.e., wireless connectivity and powering through a glass window 18). Of course, the location 16 could be at any window or the like of the home 10. Such a window 18 may be a single, double, or triple glazed glass window or any other material through which light may be transmitted.

[0018] In accordance with an embodiment as shown in FIG. 3, the CPE may include one or more outdoor units (ODUs) 20 and an indoor unit (IDU) 22. These units 20 and 22 are located/mounted on opposite sides of the window 18 (i.e., ODU 20 is mounted on an exterior surface of the window 18 and IDU 22 is mounted on an interior surface of the window) such that the units. 20 and 22, face each other and can communicate via direct line-of-sight optical communications through the window 18. The ODU 20 and IDU 22 may be of relatively small size as compared to the size of the window 18 as to not greatly impact the homeowners view through the window 18 or natural light passing through the window into the home 10.

[0019] According to this embodiment, drilling of holes through walls and/or roofs and extending data cables or wires through a wall, roof, or like structure of the home is not required. In addition, a power cable passing through the wall, roof, or like structure of the home 10 is also not required because the ODU 20 is configured to be powered by the IDU 22 via wireless power transfer or charging.

[0020] In FIG. 3, multiple ODUs 20 are shown for the purpose of showing that the CPE (i.e., ODU 20 and IDU 22) may be connected to a variety of different external networks. For instance, a cable network 24 may connect to a cable modem 26 via coaxial cable 28. The modem 26 may be directly connected to the ODU 20 or form a part thereof. In addition, a Fiber to the Home (FTTH) network (i.e., optical fiber network) 30 may connect to an Optical Network Termination (ONT) modem 32 via fiber optical cable 34. The modem 32 may be directly connected to the ODU 20 or form a part thereof. Further, a Direct-To-Home (DTH) television network 36 may communicate via satellite signals with a personal dish 38 located at the customer premises and be connected to a SAT to IP modem 40 via coaxial cable 42 or the like. The modem 40 may be directly connected to the ODU 20 or form a part thereof. Still further, a cellular mobile communication network 44 may communicate via cellular communications to an antenna 46 or the like connected or forming part of a modem 48. The modem 48 may be directly connected to the ODU 20 or form a part thereof.

[0021] The cellular network 44 may be such that the signals transmitted thereby may not readily and reliably penetrate through walls, roofs and glass of a building. Thus, CPE will be required to distribute data communications from the cellular network 44 throughout the home 10. For instance, the cellular network may be a cellular 5G (fifth generation) network or other network.

[0022] As shown in FIG. 3, any one of the ODUs 20 may communicate through the window 18 to the IDU 22. The IDU 22 may be connected to CPE 50 (i.e., a gateway device, router, or the like) providing a gateway and/or access point of a wireless local area network (WLAN) provided in the home 10. Alternatively, the CPE 50 may form part of the IDU 22.

[0023] The CPE 50 may be configured to provide a Wi-Fi network within the home 10 as discussed above and/or a gigabit Ethernet (GigE) or other ethernet connectivity, Multimedia over Coax Alliance (MoCA) connectivity, and/or G.Hn connectivity. G.Hn is a specification for home networking with data rates up to 2 Gbit/s and operation over four types of legacy wires: telephone wiring, coaxial cables, power lines, and plastic optical fiber. A single G.Hn semiconductor device is able to network over any of the supported home wire types.

[0024] An embodiment of an ODU 52 is shown in FIG. 4. The ODU 52 includes a broadband modem 54, a Light Fidelity (Li-Fi) optical transceiver 56 having one or more sets of light emitting diodes (LEDs) and photoreceptors 58, a wireless power transfer unit 60, and an inductive coil antenna 62. The broadband modem 54 may be any type of modem including those discussed above (i.e., cable (DOCSIS), ONT, xDSL, cellular, 4G/5G, SAT to IP, etc.).

[0025] The optical transceiver 56 may be a Light Fidelity (Li-Fi) optical transceiver which uses light-emitting diodes (LEDs) for wireless optical data transmission. LiFi data is transmitted by LEDs and received by photoreceptors. Visible light communications (VLC) is provided by switching the current to the LEDs off and on at a very high rate. If desired, the LEDs may be dimmed to below human visibility while still emitting sufficient light to carry data. Operation of the LEDs is controlled by a microchip or the like that modulates light imperceptibly for optical data transmission. Thus, Li-Fi technology provides a light communications system that is capable of transmitting data at high speeds over the visible light spectrum as well as via ultraviolet and infrared radiation. Unlike Wi-Fi signals, Li-Fi communications are not susceptible to electromagnetic interference and are more secure from hacking.

[0026] In addition to Li-Fi. IEEE 802.11bb light communication technology or its equivalent may also be utilized. IEEE 802.11bb defines one medium access control (MAC) and several physical layer (PHY) specifications for light-based wireless connectivity for fixed, portable, and moving stations within a local area network.

[0027] The light communications according to an embodiment may provide multi-billions of bits per second (Gbps) broadband communications, such as 2 Gbps or 5 Gbps. Gbps is a measure of bandwidth on a digital data transmission medium.

[0028] As shown in FIG. 4, the broadband modem 54 of ODU 52 connects to an external network 84 and interfaces with the optical transceiver 56 via a high-speed interface 64 and both the broadband modem 54 and optical transceiver 56 are powered by the wireless power transfer unit 60 (i.e., receiver unit converting magnetic field picked up from the receiver coil 62 and rectifying/converting to a DC voltage for powering the optical transceiver 56 and broadband modem 54). For instance, the wireless power transfer unit 60 may be configured to provide power at 5 volts or any other desired rated voltage.

[0029] The inductive coil antenna 62 enables the wireless power transfer unit 60 of the OPU 22 to be wirelessly powered. By way of example, wireless powering may be accomplished according to the Qi standard which is an open interface standard that defines wireless power transfer using inductive charging over distances of up to 4 cm (1.6 inches) and that was developed by the Wireless Power Consortium. The charging is accomplished by resonant inductive coupling. For instance, the ODU 52 may be powered by the IDU 66. According to an embodiment, the IDU 66 may be configured to deliver about 30 Watts or more or less of power through a glass window of about 3 cm thickness.

[0030] The IDU 66 may include a Li-Fi optical transceiver 68 having one or more sets of LEDs and photoreceptors 70 for transfer of data communications 72 with the Li-Fi optical transceiver 56 of the ODU 52. The Li-Fi optical transceiver 68 may communicate via a highspeed interface 86 with a network processor 74 and broadband distribution medium (i.e., Wi-Fi, Ethernet, or the like) within the IDU 66. The network processor may provide or control an access point to the WLAN within the home.

[0031] The IDU 66 may also include a wireless power transfer unit 76, an inductive coil antenna 78, and a switched-mode power supply (SMPS) 80. The SMPS 80 is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently and to transfer power from a DC or AC source to DC loads while converting voltage and current characteristics. In FIG. 4, the SMPS 80 is shown connected to an AC power source 82 and to provide the Li-Fi optical transceiver 68 and network processor 74 with power at 5 volts. The SMPS 80 may be configured to provide power, for instance at 24 volts or other rated voltage, to the wireless power transfer unit 76 which may be configured with the inductive coil antenna 78 to wirelessly power the wireless power transfer unit 60 via resonant inductive coupling 88 applied to the inductive coil antenna 62 of the ODU 52 as a receiver. Thus, the ODU 52 is powered/charged by the IDU 66.

[0032] Accordingly, the outdoor data communication unit 52 interfaces with the optical, coaxial, cellular, metropolitan wireless network, or other external network 84, and the indoor data communication unit 66 is coupled to the consumers home gateway/indoor terminating device 74. The ODU 52 and IDU 66 are coupled through a glass window 18 in the home using optical modulators to transceive data between the ODU 52 and IDU 66 via optical physical layer Li-Fi technology or the like. In addition, the ODU 52 is powered by wireless powering the ODU 52 by the IDU 66 using wireless resonant inductive coupling. The antennas 62 and 78 of the ODU 52 and IDU 66 are configured to be optimized for near field communication thus making it possible to wirelessly transmit power from the IDU 66 to the ODU 52.

[0033] The above described ODU and IDU may be provided in relatively compact sizes of relatively light weight and may be readily secured to a surface of a glass window. For example, each of the ODU and IDU may be supported by a support bracket or stand secured or fastened to the sill or surrounding structure of a window. Alternatively, the ODU may be secured to the window with adhesives, suction cups, or the like. Installation of the ODU and IDU should reduce operator liability and risk for property damage and should be able to be installed in a very short period of time. Alignment of the IDU with the ODU should be simple permitting this function to be performed by the homeowner or like untrained person. Thus, a professional installer may not be required to enter the customer premises as the IDU may be able to be secured to a surface of the window by the consumer (i.e., homeowner or the like). The connection can provide a direct line-of-sight between the optical transceivers of the ODU and IDU and thus should be immune from interference and should be able to provide high-speed data communications (i.e., up to 5 Gbps).

[0034] A system for carrying out any of the above disclosed embodiments, methods, or arrangements may include software or the like provided on a circuit board or within another electronic device and can include various routers, modems, processors, microprocessors, modules, units, components, controllers, chips, disk drives, and the like.
