Like many existing homes, my parents' home has a limited wired Ethernet network and a wireless (Wi-Fi) network covering the rest. My mom, who has rented Netflix DVDs for a while, wanted to start streaming her favorite shows in the family room and bedroom rather than waiting for disks. Prior to me coming home for Labor Day, they set up an Apple TV on the wireless network. I recommended that they switch to a wired network connection for a faster and more reliable solution.

My parents' Ethernet network is limited to the home office and a small bedroom directly above it. With the family room and bedroom on the opposite side of the house, expanding the wired Ethernet network conventionally would have been labor intensive. Fortunately, there's a wired networking solution that allows high speed Ethernet to bridge over the existing coax cable (cable TV) network in the home. It's called MoCA.

Before I get into the installation, the next step will cover a quick overview of the coax networking technology.

Step 1: What is coax networking (MoCA)?

A coax network is an extension of the existing home network onto the coax cable network in the home. Just like Wi-Fi is the ubiquitous standard for wireless home networks, MoCA is the nearly ubiquitous standard for coax networks. MoCA stands for the Multimedia over Coax Alliance. If your cable service provider offers a service called Multi-Room DVR, they are almost certainly using MoCA to enable it.

The current standard for MoCA is 1.1 and the equipment used in this project is standards compliant. 

A MoCA network is broadcasted roughly between 500MHz and 1.5GHz (1500MHz). The technology is designed so that it does not interfere with the broadcasts of traditional cable TV service. However, satellite TV, which runs on different spectrum, is not compatible with the 1.1 MoCA standard. For their respective multi-room DVR services, they use a proprietary coax networking technology. The MoCA 2.0 standard in development is expected to work for all service providers.
