MoCA

(Multimedia Over Coax Alliance) An IP-over-coaxial cable technology from the Multimedia over Coax Alliance (www.mocalliance.org). MoCA provides secure, high-speed delivery of Wi-Fi or Ethernet throughout the home wherever the coaxial cable terminates. Because the cable from the cable company is wired into many rooms in the house for TV, the MoCA network infrastructure is already in place.

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.


A Solution for Weak Signals
MoCA solves the problem of weak Wi-Fi in distant rooms or different floors. 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 where the coax terminates. (Images courtesy of Wi3 Inc., www.wi3inc.com)

Multi-room Cable TV Boxes
MoCA is also used to create a unified 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.
