Coax/Splitters Support Coexistence with Existing Services

Coexistence with existing services is required VDSL on coax (4-12 Mhz), Cable operator upstream (5-42 Mhz), Over-air (54 – 806 Mhz), Cable operator downstream (50-860 Mhz) Coax and splitters support reliable communications above 860 Mhz 1

Cable Solution

MoCA enables cable STB with integrated PVR or cable modem to be a whole-house solution extending PVR & ITV services to all TVs Ethernet directly to a PC No consumer adoption or education issues Consumer is not aware of the presence of any network.

No new wires, connections, or behavior Where’s the home network in this picture? Invisible to the consumer

DBS Solution

DVR and whole-home DVR are DBS answer to cable operator VOD Normal DBS installation today: A truck roll is required to later enable another room. Run a new cable and punch a new hole plate in the wall, using normal practice: $150

Sept 1, 2005

Here, notice that MoCA enables a retail client, no truck roll, to be added at anytime, and at any existing outlet. Puts DBS service at “outlet parity” with Cable Operator. Every existing outlet has DBS signal there via MoCA. Saves $150 future truck roll. Reduces initial installation $45/room.
