  2. About MoCA • MoCA’s Mission To develop and promote specifications and certify interoperable products that enable distribution of entertainment within the home using the existing in-home coaxial cabling • Board of Directors • Comcast, Cox, Echostar, Entropic, Linksys, Motorola, Panasonic, RadioShack, Toshiba, Verizon • MoCA Activities • Develop technical specifications, validate through field tests, certify MoCA enabled products as interoperable, and ensure access to necessary intellectual property for all members on reasonable and non-discriminatory terms • Join MoCA: http://www.mocalliance.org/en/join/index.asp Home Networking Digital Entertainment Without Compromise

  3. Drivers for Home Multimedia Networks • Cable operator whole-home DVR and triple play • DBS whole-home DVR • Telco “triple-play”: video, voice, data • Retail • Home server & client for multimedia • DVD-DVR combo • Media Center PC to Media Center Extender/TV • Backbone for WiFi Home Networking Digital Entertainment Without Compromise

  4. Data rate Simultaneous multiple HDTV,SDTV, data, voice gaming, ... Example: 1HD FF, 1 ATSC, 2 SD double hop, 10 Mbps data 36 - 128 Mbps Customers ask MoCA for 60 to 100+ Mbps net throughput Quality & reliability Does not degrade when other services are added Does not degrade when neighbor or housemate runs services Does not degrade when home appliances are turned on Multimedia Throughput Needs Home Networking Digital Entertainment Without Compromise

  5. The Home Usage Model And Connectivity • Each room can be a source and sink of multi-media • Consumers may • Move equipment to other rooms • Add a cable or splitter • Mandatory connectivity model • Room-to-room, peer-to-peer, full mesh, all outlets source and sink • Backwards through splitters • MoCA is the only technology that provides no-excuses networking room-to-room over in-home coax as is Needed Connectivity Model Desirable Not Desirable Home Networking Digital Entertainment Without Compromise

  6. A Unique Environment: Coax room-to-room Room-to-room characteristics dictate and require a custom PHY/MAC solution for ubiquitous coverage Frequency Response Long Path: F =>B Frequency Response Short Path: F => E Home Networking Digital Entertainment Without Compromise

  7. Coax/Splitters Support Coexistencewith 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 5-42 Upstream 4-12 VDSL 54-806/860 Off-Air/CATV MoCA MoCA MoCA … 1 2-38 MoCA 54-806/860 Off-Air/CATV-down 950-2150 Satellite L-Band 2 5-42 Upstream 4-12 VDSL 54-806/860 Off-Air/CATV MoCA 950-2150 Satellite L-Band 3 Home Networking Digital Entertainment Without Compromise

  8. 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 Cable Solution Home Networking Digital Entertainment Without Compromise

  9. 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 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. DBS Solution • DVR and whole-home DVR are DBS answer to cable operator VOD Home Networking Digital Entertainment Without Compromise

  10. Telco Solution • Video, voice, data via FTTH or xDSL • ONT or DSL-GW, home router, DVR, IPSTBs, PCs, ... • Where is the WAN and home network separation/routing? Home router for FTTH DSL-GW for xDSL • Are you “double hopping?” • Where is the content source? Every room can be a source Home Networking Digital Entertainment Without Compromise

  11. One example: enabling PC to TV DVR will become a standard feature of home desktops Retail Solution Home Networking Digital Entertainment Without Compromise

  12. Field Testing of MoCA • Goal - validate performance and coverage in real world conditions • Field Test conducted in >240 homes • Multiple cities (>120 zip codes) • Multiple cable providers • All MoCA Members participated in tests • Tests conducted under normal living conditions • No modifications to cable plant • Existing devices connected to cable • Existing services connected to cable • Tests systems designed for use by non-technical persons • MoCA nodes deployed at each home cable outlet • Test coordinated by laptop PC • Collected multiple statistics on coverage, performance, and link Home Networking Digital Entertainment Without Compromise

  13. Field Test Results • Packet Error Rate less than 1E-6 • Latency less than 5ms • Net usable (MAC) data rates, with no changes to the home coax system: • 97% of all paths in all homes achieved ≥ 100 Mbps • 100% of homes achieved > 120 Mbps on at least one path • 90% of homes achieved ≥ 80 Mbps on every path in the home • Net usable (MAC) data rates, with simple remediation to the installed coax cable system: • 100% of homes achieved ≥ 95 Mbps on every path in the home Home Networking Digital Entertainment Without Compromise

  14. MoCA Performance/Coverage Home Networking Digital Entertainment Without Compromise

  15. Summary • Home usage model • room-to-room, peer-to-peer, full mesh connectivity • 100 Mbps net throughput • No-excuses, glitch-free video • Consumer or Service provider enabled • Medium for whole home reliable, maintainable coverage • Connections collocated with TV’s and other video devices • Coexists with existing services and devices • Medium used “as-is” – no new cables, splitter replacements • Real world validation • Large scale, multiple company field test • >100Mbps in 97% of all connections • Reasonable remediation for other connections • MoCA meets all the requirements for home networking digital entertainment without compromise Home Networking Digital Entertainment Without Compromise
