    Power Line Access Technology Home network distribution Technology up to 14Mbps

    Smart homes, Telephony, health care Home networking, INTERNET ACCESS

    For narrow band power line: CENELEC EN 50065 (up to 150 Kbps)

    For broad band power line: No standards yet approved Two main technologies under discussion:

    Enikia, Intellon Homeplug 1.0 Spec from Homeplug Powerline Alliance already approved

    (Based on Intellon technology) In home networking there are several competitors. Each one can be the

    dominant one in the near future Wired

    Standard Ethernet IEEE 802.3, HomePNA, Powerline Wireless

    Wireless Ethernet 802.11x, HomeRF based on SWAP Bluetooth

  • 22ndnd NGNNGN--I WorkshopI Workshop

    Satellite Access Network Technology Wide area coverage - Multi-Point Connections / Broadcast Delivery allows shared

    connections with multiple points. High bandwidth - up to 100 Mbps for current satellites Increased reliability and security. Cost independent of distance. Market evolution:

    Cost-effective satellite solutions already exist Satellite capacity improvements Component cost reductions

    Main Drivers: Dispersed sites - installed and activated more quickly than terrestrial communication lines Scalability - is rapidly expandable and scalable to accommodate growing needs No International Bottlenecks - Bypasses the limitations and congestion of local terrestrial networks. Reach - Reaches locations where there is no existing infrastructure, or limited facilities Access to Internet and to public switched networks

    Areas of current and future standards evolution: ETSI Working Group on Broadband Satellite Multimedia (BSM):

    Definition of satellite system architecture and service requirements for broadband services Definition of network architectures and interfaces protocols leading to air interface standards,

    and user terminal specifications To produce specifications for interoperability between satellite networks and other networks

    Related standards: Digital Video Broadcasting Project (DVB)- global standard for the delivery of digital TV and data

    services ESA RSAT group is working towards open recommendations for standards for satellite terminals
