22ndnd NGNNGN--I WorkshopI Workshop

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

Current Status

• Still in study/research phase • Need more input and related reports

from other NGN-I projects• WP2, WP3 and WP4 being done in

parallel• Difficulties

– Slide in deliverable deadlines – Circulate a joint D2, D3 and D4 in

February– Propose end of project to extend to April
