  MoCA Access is a variation of MoCA that has additional management features. Businesses and institutions can use it to distribute Internet access for multi-dwelling facilities such as a hotel, apartment building, resort, hospital, or educational facility. It is generally a much more expensive class of products targeted at businesses.

  Backhaul for a Mesh Wi-Fi System (i.e., a wired backbone for the Wi-Fi satellites).

  Extend wireless coverage.

  Use existing coax cables as a replacement for Ethernet cables.

  Get Internet access to hard-to-reach places in your home.

  Use wired connections to avoid Wi-Fi interference from neighbors.

  Avoid the latency of Wi-Fi while playing games on consoles and computers.

  A secure alternative to Wi-Fi when using a MoCA POE Filter.

  Use Cases for MoCA Access, which is targetted at businesses with a point-to-point or point-to-multipoint network architecture, include:

  Distribute Internet access for a hotel, resort, hospital, educational facility, or multi-dwelling unit such as an apartment building.

  Distribute Fiber to the Building (FTTB) Internet, using existing coax wiring.

  Network offices, restaurants, and the hospitality industry, using existing coax wiring.

  Provide a wired backhaul for 4G/5G.

  Setting up a MoCA Home network is quite simple, as it often requires no software configuration.

  If you have a router that supports MoCA already, you need a minimum of one additional MoCA adapter.

  If your router does not support MoCA, or you want to create a separate coax network for MoCA, then you’ll need at least two MoCA adapters.

  MoCA adapters may come with short Ethernet cables and a coax splitter.

  If your MoCA adapters don’t come with Ethernet cables, you’ll need Cat 6 or Cat 6a Ethernet cables for each adapter.

  If your MoCA adapters don’t come with coax cables, you’ll need short RG-6 coax cables to connect each adapter to the wall.

  If your MoCA adapters don’t come with coax splitters and you are connecting multiple cables, you’ll need MoCA compatible coax splitters that support up to 1625 MHz.

  To ensure that the MoCA communication is not accessible by a neighbor, you’ll need to ensure that the coax cable coming into your home has a MoCA POE Filter. MoCA POE Filters block 1 GHz frequencies and also reflect them, which improves MoCA communication.

  Check out my Ultimate Cable Internet Wiring & Optimization Guide for additional cable setup guidance.

  While older versions only use a 1 Gbps network port, the ECB7250 uses a 2.5 Gbps port, allowing for maximum network utilization.

  Includes most of what you’ll need, including two adapters and power supplies, two network cables, two coax cables, and a coax splitter.

  The instructions are a bit lacking, but it’s straightforward to set up initially. The instructions seem to avoid discussing the MPS button, but that won’t be needed for most installations.

  You’ll probably want also to buy a MoCA POE Filter if your ISP didn’t already install one.

  The Actiontec WCB6200Q is an excellent solution if you:

  Have a modem-router combo with MoCA support; or

  Want to use MoCA for Ethernet backhaul from this Wi-Fi extender to the router.

  4×4 802.11AC Wi-Fi can use the full bandwidth of the MoCA 2.0 bonded connection (1 Gbps) with devices that support streaming to all four antennas (4×4 MIMO).

  It only supports MoCA 2.0 Bonded speeds, but that should be enough for most internet streaming purposes.

  MoCA is incompatible with Satellite TV, Dish, Direct TV, and AT&T U-verse TV, which use the same frequency bands.

  Coax amplifiers and splitters will need to support the frequencies of up to 1625 MHz used by MoCA.

  Using MoCA over RG-6 coax cables is best, but it may still work over older cables.

  MoCA adapters are generally backward compatible but will run at lower speeds when used with older versions.

  MoCA Point of Entry Filters filter out the 1 GHz+ frequencies used by MoCA devices.

  MoCA devices commonly include DVRs and MoCA adapters and can be used for Ethernet communication over a coax cable.

  MoCA POE Filters are beneficial for privacy, to prevent leaking data to your nearby neighbors, as well as reducing noise on the line.

  They also reflect the MoCA frequencies, which can be desirable for improved MoCA device communication.

  Your cable provider may have already installed a MoCA POE Filter with one of these labels:

  Do not remove—Required for multi-room DVR operation

  Do not remove—Required for whole-home DVR operation

  Do not remove—Required for any-room DVR operation

  Despite the phrasing, these filters also apply to MoCA adapters for Ethernet usage. The main reason for this wording is that DVR set-top boxes are a more common usage of MoCA.

  MoCA 2.5 is the latest commercially available version. MoCA 2.5 provides 2.5 Gbps of network throughput and supports up to 16 adapter nodes.

  MoCA versions 2.0 and up include additional security features, such as MoCA protected setup (MPS) and signal power and network management features.

  The MoCA 3.0 specification is complete, but it is speculated by Jeff Heynen, Dell’Oro Group Vice President, that manufacturers may never produce MoCA 3.0 Home products.1

  This is based on the decline of the pay-TV cable market, transition to cloud-based DVRs, and advancement of Wi-Fi 6. MoCA silicon is often driven by demand and commitments from operators and service providers.

  Companies providing MoCA Access products and solutions include InCoax, Translite Global, and Luster Terraband.

  Another important consideration is regarding MoCA POE Filters. These filters are necessary for creating a network barrier so that your devices do not communicate with your neighbor’s devices and vice versa. However, if your internet service provider uses high-frequency DOCSIS 3.1 and 4.0 channels above 1 GHz, a 1 GHz low pass filter may block those channels. To avoid this, you could segregate your modem from the rest of the MoCA network, as described below: How to Use Multiple Partitioned Coax Networks With MoCA.

  By default, most MoCA adapters will not be secure. However, they can be secured in three different ways:

  MoCA POE Filter – A Point of Entry filter is a low pass filter that filters out and reflects MoCA signals. POE Filters will prevent your devices from communicating with nearby neighbors. MoCA signals can travel up to about 300 feet.

  Encryption – MoCA 2.5 adapters typically support some form of encryption, although it often requires manual configuration. Node password sharing is possible via an MPS (MoCA protected setup) button, similar to the WPS button on many Wi-Fi devices.

  Coax partitioning – By disconnecting your MoCA coax cables from the cables that leave the property, you prevent other devices from accessing your data via coax.

  MoCA adapters typically work just fine over the same coax lines as you use for your internet. However, if you want to minimize potential interference for your cable modem and maximize security, you can separate your coax into two networks. You can use one line going from the street to your cable modem. You can then use another separate coax line to connect the two MoCA adapters.

  This configuration may not be as typical. It would require you to run an Ethernet line between two rooms, to access another coax wall outlet.

  Network isolation (multiple partitioned coax networks) is ideal for maximizing security and minimizing potential cable interference. A single network is suitable if you are more interested in a simplified configuration. Single networks are also pretty secure with a MoCA POE Filter.

  Some cable modems have built-in support for MoCA, which means that you would only need a single additional MoCA adapter to create a MoCA network. However, most modems on the market currently only support MoCA 2.0.

  One excellent use case for a MoCA network is as a Mesh Wi-Fi System’s wired Ethernet backhaul. Ethernet backhaul means using coax cables to connect the main mesh router to mesh Wi-Fi satellite nodes. Doing so would provide a fast connection between the router and satellites, maximizing Wi-Fi speeds throughout your house.

  Mesh Wi-Fi Systems are becoming more popular as they simplify getting Wi-Fi signals into hard-to-reach locations of a home. They create a Wi-Fi network with multiple Wi-Fi access points to spread out the Wi-Fi coverage. Each of these Wi-Fi access points is called a satellite node.

  However, as each satellite node in a Mesh System is just repeating Wi-Fi data to transport it to and from the router, there may be a performance penalty.

  To avoid the lower performance via satellite nodes, you can run Ethernet cables between the main router and satellite nodes. Using this wired connection is called “Ethernet Backhaul.”

  The drawback to this solution is that your home may not already be wired for Ethernet. To avoid adding additional Ethernet wiring, you can instead use a coax Ethernet backhaul.

  Coax Ethernet backhaul means that you are using your home’s coax wiring with MoCA adapters to connect the router to the satellite nodes. Wired backhauls will result in a fast connection throughout your house, ideally without needing additional in-wall wiring.

  Ethernet is the broad set of networking technologies, which includes those used in a home network. The same communication which typically occurs over Ethernet cables (e.g., Cat 6a Ethernet cables) can also occur over a coax cable if you use MoCA adapters.

  Ethernet over coax provides the same functionality as Ethernet over typical Ethernet cables (e.g., Cat 6a). The primary advantage of using a MoCA network rather than traditional Ethernet cables is that it provides the convenience of using a home’s existing coax cables for Ethernet communication.

  Ethernet is the broad set of networking technologies, which includes those used in a home network. The same communication which typically occurs over Ethernet cables (e.g., Cat 6a Ethernet cables) can also occur over a coax cable if you use MoCA adapters. Wi-FI, on the other hand, is the wireless sibling to Ethernet. While MoCA doesn’t replace the Wi-Fi portions of a home network, it can work together with Wi-Fi devices. In particular, it can connect distributed wireless nodes across a home.

  MoCA can work in coordination with Wi-Fi devices to create a fast wireless network. Alternatively, MoCA could create a high-speed wired network, which may have higher throughput and lower latency than Wi-Fi communication.

  MoCA 2.5 network has a max speed of 2.5 Gbps. The latest MoCA 2.5 adapters have 10/100/2500 ports, allowing full utilization of the network’s throughput.

  MoCA 3.0, which is expected to have silicon available in 2022 or 2023, will have a maximum network throughput of 10 Gbps. However, it is unclear if MoCA 3.0 Home adapters will be produced.
