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)?
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.
