Communications within a residential or commercial network are generally wired or wireless, both of which have advantages and drawbacks with respect to the other. For example, wired communication is often faster and more reliable, while wireless communication provides ease of use, mobility, and fewer wires, but often at the cost of speed and reliability.
Further, in order to extend wireless networks, repeaters and access points are often used. Both repeaters and access points require a power source to operate. Repeaters produce a second network with a second service set identifier (SSID). To use the repeater, client devices have to connect to the second network. In the subscriber's premises, the repeater is in one geographic location and overlaps the first network; further, repeaters operate in half-duplex mode (or waiting to listen before re-transmitting signals) effectively cutting data rate in half.
Moreover, to maximize range, the repeaters are often positioned at the outer extent of the effectiveness of the wireless network established by the primary router. However, this is typically a point where packet-dropping is problematic due to signal weakness and interference from obstacles or other wireless signal congestion, forcing the user device to retransmit signals and resulting in reduced bandwidth and slow communication speeds. Access points branch out in one direction from the source router and similarly operate in half duplex which halves the communication speed or bandwidth.
A system for communicating wireless frequency band signals over a cable network includes a wireless over cable (WoC) amplifier configured to communicate wireless frequency band signals to and from a modem, the modem being connected to an internet service provider network. The WoC amplifier includes an antenna in wireless communication with the modem, a wireless signal amplifier electrically connected with the antenna, an impedance transformer electrically connected with the wireless signal amplifier, and an output port. The system also includes a WoC splitter including an input port configured to communicate external network signals with the Internet service provider network, a frequency band separation device configured to separate the wireless frequency band signals from the external network signals, and at least one integrated port electrically connected to the frequency band separation device and the WoC amplifier. The at least one integrated port is electrically connected to the output port of the WoC amplifier directly or by one or more cables. The WoC splitter also includes a plurality of wireless frequency ports electrically connected to the frequency band separation device. The frequency band separation device is configured to transmit the wireless frequency band signals from the WoC amplifier to the wireless frequency ports, transmit the external network signals from the input port to the integrated port, block the wireless frequency band signals from being transmitted from the wireless frequency ports to the input port, and block the external network signals from being transmitted from the input port to the wireless frequency ports. The system further includes a WoC adapter electrically connected to the WoC splitter via one or more coaxial cables, wherein the WoC adapter is configured to receive the wireless frequency band signals from the WoC splitter and transmit the wireless frequency band signals wirelessly to one or more wireless communication devices.

The WoC splitter is configured to communicate the wireless frequency band signals with the WoC amplifier directly or via the one or more first cables. The system also includes a WoC adapter electrically connected to the WoC splitter via one or more second cables. The WoC adapter is configured to receive the wireless frequency band signals from the WoC splitter via the one or more second cables, and transmit the wireless frequency band signals wirelessly to one or more wireless communication devices.

Certain embodiments of the disclosure will hereafter be described with reference to the accompanying drawings, wherein like reference numerals denote like elements. It should be understood, however, that the accompanying drawings illustrate only the various implementations described herein and are not meant to limit the scope of various technologies described herein. The drawings show and describe various embodiments of the current disclosure.
Embodiments of the present disclosure may provide a wireless (e.g., WIFI®) over cable (“WoC”) network or system that includes a mesh distribution architecture, which provides economical and reliable extension of wireless communication (e.g., WIFI) signals, while maintaining a single SSID and security credentials. The WoC network may begin at the premises modem or wireless router (or another source) using a WoC amplifier for connection to an (e.g., pre-existing) in-home coaxial cable network (or wired back haul). The cable network may also include one or more WoC splitters, which may be configured for use in wireless frequency bands such as 2.4 GHz and/or 5 GHz (it will be appreciated that any suitable wireless frequency band may be employed, and the two listed are not to be considered exclusive). The wireless frequency band signals are distributed to any number of end points via an existing cable network. The end points, in turn, may be wall plates attached to a wall, which may include or have connected thereto a WoC adapter, which may transmit the wireless frequency band signals wirelessly via an antenna and receive wireless signals from connected devices.
The WoC system may thus represent an advancement over conventional WIFI mesh networks, extenders, and Ethernet over coaxial communications (e.g., multi-media over coaxial alliance or MoCA protocol communications). For example, the WoC system may be simpler in setup and use, less expensive per coverage area, maintain network security, management, SSID and password, require power at only one location, have a reliable low loss path around or through premise structures, and have minimal delay (or latency). Thus, the wireless over cable network may provide a solution for high bandwidth, low-latency required applications, such as gaming and video streaming.
A WoC amplifier 106 may be in communication with the modem 102. For example, the WoC amplifier 106 may be in wireless communication with the modem 102, e.g., using an antenna in communication with the antenna of the modem 102. The WoC amplifier 106 and the modem 102 may be closely proximal to one another, which may promote high reliability and low latency wireless communication therebetween. In another embodiment, the modem 102 and the WoC amplifier 106 may each have a wired communication (e.g., coaxial) port, and the modem 102 and the WoC amplifier 106 may be in wired communication with one another via a cable extending between the ports thereof. Furthermore, the communication between the WoC amplifier 106 and the router 102 may be in a wireless frequency band, e.g., 2.4-2.5 GHz or 5.0 GHz, or the like. Thus, as the term is used herein, “wireless frequency band signals” refers to signals in a wireless frequency band (e.g., wireless frequency band signals such as 2.4-2.5 GHz or 5.0 GHz), and it will be appreciated that such signals may be communicated between devices wirelessly and/or via coaxial (or other types of) cables for transmission within the wired backbone.
The system 100 may also include a WoC splitter 108, which may be in communication with the WoC amplifier 106 via a coaxial cable or another type of cable suitable for transmitting wireless frequency band signals. The WoC splitter 108 may be configured to split downstream signals from the WoC amplifier 106 into two or more legs, and provide upstream signals to the WoC amplifier 106. In some embodiments, the WoC splitter 108 may be a passive device, receiving power only through the wireless frequency band signals (or any other frequency signals) sent thereto for communication to other devices.
The system 100 may also include a plurality of WoC adapters 110 (four are shown by way of example). The WoC adapters 100 may be configured to receive downstream signals from the WoC splitter 108 and transmit the downstream signals wirelessly to one or more wireless communication devices 112 (four shown) in proximity thereto. The WoC adapters 110 may also be configured to receive upstream signals from the wireless communication devices 112 and transmit the upstream signals to the WoC amplifier 106. The WoC amplifier 106 may then transmit (e.g., wirelessly) the wireless frequency band signals to the modem 102, which may convert the wireless frequency signals to external network signals (e.g., CATV), and communicate the signals to the CATV network 104. It will be appreciated that a single WoC adapter 110 may be configured to communicate with multiple wireless communication devices 112.
As mentioned above, the system 200 may be configured to distribute wireless frequency band signals, which, again, are those signals in a wireless frequency band (which may be different from both the MoCA frequency band and the CATV frequency band). Accordingly, the WoC system 200 may include the modem 102, the WoC amplifier 106, the WoC splitter 108, and the WoC adapters 110, which are configured to communicate wirelessly with wireless communication devices 112. The WoC components may be configured as discussed above with reference to
In addition, between the CATV network 104 and the modem 102, there may be a MoCA splitter (e.g., an entry adapter) 202 along with a point-of-entry (POE) filter 204. The MoCA splitter 202 may be configured to separate (e.g., passively or actively) CATV frequency band signals from MoCA frequency band signals. The MoCA splitter 202 may further be configured to communicate MoCA signals among MoCA devices 206 (two shown) and CATV-MoCA devices 210 (two shown), while allowing the CATV signals to/from only the CATV-MoCA devices 210 and preventing CATV signals from reaching the MoCA devices 206. The POE filter 204 may be configured to block MoCA frequency band signals from exiting the system 200 and being received back to the CATV network 104. In an embodiment, the MoCA splitter 202 may also communicate the CATV signals, but not the MoCA signals, to the modem 102 for transmission via the WoC amplifier 106 to the WoC splitter 108 and then to the WoC adapters 110.
The WoC splitter 302 may be configured to separate CATV signals, MoCA signals, and wireless frequency band signals, e.g., based on the different frequency bands thereof, as will be described in greater detail below. The WoC splitter 302 may thus provide the same functionality as the MoCA splitter 202, with the addition of handling distribution and receipt of wireless frequency band signals.
Accordingly, the WoC splitter 302 may receive downstream CATV signals from the CATV network 104 via the POE filter 204. The WoC splitter 302 may pass these downstream CATV signals to the CATV-MoCA (or CATV-only) devices 210, as well as to the WoC amplifier 304. The WoC amplifier 304 may pass the downstream CATV signals to the modem 102, e.g., directly or via a coaxial cable forming a wired connection. The modem 102 may then transmit the wireless frequency band signals via one or more wireless links (i.e., “wirelessly”) back to the WoC amplifier 304. The WoC amplifier 304 may transmit the wireless frequency band signals to the WoC splitter 302 directly or via a wired connection. The WoC splitter 302 may distribute the signals to the WoC adapters 110.
The WoC splitter 302 may also communicate MoCA signals between the CATV-MoCA devices 210 and the MoCA-only devices 206. The WoC splitter 302 may prevent at least some of the upstream MoCA signals from reaching the CATV network 104, and the POE filter 104 may also prevent the upstream MoCA (and/or wireless frequency band) signals from reaching the CATV network 104. In addition, the WoC splitter 302 may receive upstream WoC signals from the WoC adapter 110 (received from the wireless communication devices 112). The WoC splitter 302 may route these upstream wireless frequency band signals to the WoC amplifier 304. The WoC amplifier 304 may wirelessly transmit the wireless frequency band signals to the modem 102, which may receive the wireless frequency band signals, adjust the frequency thereof into the CATV frequency band, and return them to WoC splitter 302 (e.g., via the WoC amplifier 106) directly or through a coaxial cable connection. The WoC splitter 302 may then route the external network (CATV) signals back to the CATV network 104 directly or via the POE filter 204, e.g., via coaxial cable.
The WoC adapters 110 may thus be connected to respective wall plates 410, and receive wireless frequency band signals therefrom, which the WoC adapters 110 may in turn transmit wirelessly to nearby wireless communication devices 112. Similarly, the CATV-MoCA devices and MoCA-only devices may be coupled (e.g., via cable connections) to the wall plates 410, and may receive either MoCA-only signals or combined CATV and MoCA signals therefrom. The wall plates 410 may also be configured to handle upstream communications in the same frequency bands.
As shown, the WoC amplifier 106 may include a wireless signal amplifier 500, an antenna 501, and an impedance transformer 502. The antenna 501 may be configured to communicate with the modem 102 (e.g.,
Further, the impedance transformer 502 may be coupled to an output port 504, which may be configured to bidirectionally communicate with the WoC splitter 108 (e.g.,
Thus, the diplexer 550 may combine low-frequency CATV signals from the modem 102 with high-frequency wireless frequency band signals from the wireless signal amplifier 502, and provide the combination thereof to the WoC splitter 302. Further, the diplexer 550 may block the relatively high frequency wireless frequency band signals from being transmitted to the modem 102 over the coaxial cable, while blocking the CATV signals from being received at the antenna 501. Accordingly, the WoC amplifier 106 of
Accordingly, downstream CATV signals may be received via the integrated port 652 and provided to the input port 650 and prevented from reaching the splitter 654. Downstream wireless frequency band signals may be received via the integrated port 652 and passed to the splitter 654 via the high-pass terminal of the frequency band separation device 651. The splitter 654 may split the wireless frequency band signals and distribute copies thereof to the legs 656. Upstream wireless frequency band signals may be received through the wireless frequency ports 658, combined at the splitter 654, provided to the integrated port 652 via the high-pass and common terminals of the frequency band separation device 651, and blocked from reaching the input port 650 by the frequency band separation device 651.
In each of the WoC splitter embodiments provided herein, each of the splitters contained therein may be any one or more of a broad band ferrite splitter, a high-band resistive splitter or a Wilkinson splitter, as appropriate.
