    • Overview of today’s presentation ;
    • Network Topologies in today’s broadband world..
    • Bandwidth needs of our clients today..
    • Vast market size for all home networking Technologies..
    • Largest market size is existing dwelling network RETRO-FIT.
    • Our wire, coax, is the best transmission media for retrofit use.
    • Not here to sell you anything..

    • MoCA - Established in January 2004 by some of the most respected, brand name, consumer broadband service providers and OEMs in the world; Comcast, Cox Communications, Echostar, Entropic, Linksys, Motorola, Panasonic, Radio Shack, Toshiba & Verizon.
    • Use existing coaxial cabling—installed in 90% of U.S. households. Coax is the medium for video.
    • No new wires, truck rolls or interference with other technologies and mediums.
    • Complementary to wireless—extends wireless backbone in home.
    • Only wired home entertainment networking standard in full deployment (Verizon FiOS)
    • More than 40 certified products (STBs, ONTs, gateways, home routers, etc.)
    • Consumers will tolerate a dropped cell phone call, but they will not tolerate latency in their video.
    • MAC throughput included 175Mbps (MoCA1.1)
    • Constellation sizes up to 256 QAM
      • Allowing for future 270Mbps PHY rate
    • Spectrum utilized - Bandpass of 875 to 1525Mhz.
      • 50Mhz Bandwidth, provides operation in ALL APPLICATIONS space on coax.
    • Dynamic range >70dB
    • MoCA 1.1 supports up to 16 nodes.
    • PHY is bit loaded OFDM (Orthogonal frequency-division multiplexing) that allows for optimum rates for any channel.
    • MoCA’s “I-LINE” probes each connection seeking optimization of transmission. Like cable modems will seek best transmission frequency and path.
    • Fully coordinated and synchronized network. Network controller grants transmission slots based on node request-grant, “I-LINE” compliance. Network controller is automatically selected.
    • QoS (Quality of Service) – Differentiates needs of video, voice and gaming.
      • Bandwidth reservation per channel or flow via PARAMETERIZED QoS.
            • Orthogonal frequency-division multiplexing ( OFDM ) — essentially identical to Coded OFDM ( COFDM ) and Discrete multi-tone modulation ( DMT ) — is a frequency-division multiplexing (FDM) scheme utilized as a digital multi-carrier modulation method. A large number of closely-spaced orthogonal sub-carriers are used to carry data . The data is divided into several parallel data streams or channels, one for each sub-carrier. Each sub-carrier is modulated with a conventional modulation scheme (such as quadrature amplitude modulation or phase shift keying ) at a low symbol rate , maintaining total data rates similar to conventional single-carrier modulation schemes in the same bandwidth.
            • OFDM has developed into a popular scheme for wideband digital communication , whether wireless or over copper wires, used in applications such as digital television and audio broadcasting, wireless networking and broadband internet access.
            • The primary advantage of OFDM over single-carrier schemes is its ability to cope with severe channel conditions — for example, attenuation of high frequencies in a long copper wire, narrowband interference and frequency-selective fading due to multipath — without complex equalization filters. Channel equalization is simplified because OFDM may be viewed as using many slowly-modulated narrowband signals rather than one rapidly-modulated wideband signal. The low symbol rate makes the use of a guard interval between symbols affordable, making it possible to handle time-spreading and eliminate intersymbol interference (ISI). This mechanism also facilitates the design of single-frequency networks , where several adjacent transmitters send the same signal simultaneously at the same frequency, as the signals from multiple distant transmitters may be combined constructively, rather than interfering as would typically occur in a traditional single-carrier system.

    • HomePNA - Founded in June 1998, HomePNA is led by eight forward-thinking companies; AT&T, Agere Systems, Broadcom, Cisco-Scientific-Atlanta, Conexant, 2Wire, Hewlett-Packard Co. and Mototola,
    • HomePNA 3.1 enhances the HomePNA 3.0 specification, which was standardized by the ITU International Telephone Union) in May 2005.
    • HomePNA 3.1,released in Dec. 2006, increases data rates over existing home wiring up to 320 Mbps. The HomePNA 3.1 specification helps simultaneously distribute triple-play IPTV, voice and Internet data services as well as other networked entertainment data throughout the home.
    • Use existing coaxial & twisted pair cabling—installed in 98% of U.S. households. Coax is the medium for video.
    • No new wires, truck rolls or interference with other technologies and mediums.
    • Wired home entertainment networking standard in full IPTV deployment (AT&T U-Verse).
    • More than 60 certified products; (STBs, ONTs, gateways, ethernet/HPNA bridges, home routers, etc.)
    • Existing services Phone, fax, DSL, Satellite or off-the-air TV viewing are not disrupted since HomePNA operates at different frequencies on the same coax or phone wires.
    • The newest products offer data rates up to 320Mbit/s providing enough capacity to carry many High definition TV (HDTV) and standard definition TV (SDTV) video streams.
    • Guaranteed QoS eliminates the "collisions" on the network that occur with Ethernet. It enables "real time" data streams such as IPTV (AT&T U-Verse) to be delivered without interruption.
    • A maximum of 64 devices can be connected.
    • The devices can be up to a thousand feet (300 m) apart on phone wires and multiple thousands of feet apart over coax, more than sufficient for homes.
    • Uses standard Ethernet drivers making it easy to add to any product with an Ethernet port without regard to operating system.
    • Straightforward to add other technologies such as 802.11 Wi-Fi to create a hybrid wired/wireless home network .
    • The technology works in Multi-Dwelling Units (MDU) such as apartment buildings for delivering triple play services to apartments or distributing the services within apartments.
    • Primary disadvantages of HomePNA 3.1,doesn't coexist with DOCSIS on the same in-dwelling coax.
  • RJ-11 HPNA port provides a 4-31Mhz 135 ohm interconnection to HomePNA compatible NICs and routers. "F" PhonePNA port provides a 4-31Mhz bandpass and 75 ohm interface to broadband coaxial cable. "F" Cable TV port allows full broadband utilization from 54Mhz to 1Ghz for RF analog and digital cable television whole house distribution. Jumper terminates in a standard RJ-11 male jack and the lenght is typically 8".
