Definition: MoCA
(Multimedia Over Coax Alliance) MoCA takes advantage of homes and apartments that have cable TV wired into most rooms. For people who want wired Internet access instead of Wi-Fi or for those who have poor Wi-Fi reception, MoCA enables both Ethernet and Wi-Fi to travel over the existing cable TV infrastructure.
MoCA Rides Above TV and Internet Signals
MoCA signals operate above 1 GHz; higher than the frequencies used by the cable company's TV channels and Internet service. A filter is used at the service entrance to prevent interference between MoCA signals and the cable plant.

This MoCA bridge from Wi3 adds Ethernet to the coaxial cable, and MoCA units with Wi-Fi can be added in any room in the house with a cable TV socket. (Images courtesy of Wi3 Inc.)
MoCA can also create a multi-room DVR system whereby a TV program recorded in one room can be played back in another. The Comcast Xfinity unit (bottom) is the main TV set-top box, which connects via MoCA to any number of smaller satellite units (top) for TVs in other rooms.
