MoCA networks (short for Multimedia over Coax Alliance, the industry organization that manages the standard) are devices that use coaxial cables to send data to and from the Internet.

If you’ve ever streamed a TV show through your cable box or used your cable company’s cloud-based DVR to watch something you recorded, you already know how a MoCA network works.

The devices connect your router to your home's coaxial networks. You can then connect a second adapter to a media player directly to another coaxial port or a network extender to the port.

You don't need cable internet; just an internet connection and coaxial cables in your home.
