I nternational Telecom m unication Union ITU-T Session 6 : Broadband Access Broadband Access Session 6 : Highlights & Conclusions Highlights & Conclusions VDSL2 - - Martin SCHENK ( Martin SCHENK (Infineon Infineon Technology, Germany) Technology, Germany) VDSL2 PON - - Yukio NAKANO (Hitachi, Japan) Yukio NAKANO (Hitachi, Japan) PON Cable TV - - Naoyoshi Naoyoshi NAKAMURA (NHK, NAKAMURA (NHK, Japan Japan) ) Cable TV WiMAX - - Mitsuo Mitsuo NOHARA (KDDI Corporation, Japan) NOHARA (KDDI Corporation, Japan) WiMAX Andrew Nunn Vice-Chairman ITU-T SG15, BT, UK I TU-T W orkshop “NGN and its Transport Netw orks“ Kobe, 2 0 -2 1 April 2 0 0 6
Highlights from Presentation 1 “VDSL2 ” ITU-T o ITU Consent in May 2005 (Approved in February 2006) o Multiple profiles defined to address regional and application specific requirements o ADSL/ 2/ 2+ interoperability o Worldwide subscribers to Digital Video Recording (DVR) services will rise by a factor of seven between 2005 and 2010 o Polymer Opt ical Fibre (POF) solut ion for Home Networking? I TU-T W orkshop “NGN and its Transport Netw orks“ Kobe, 2 0 -2 1 April 2 0 0 6 2
Highlights from Presentation 2 “PON” ITU-T o Very high speed data up to 1 Gbit/ s to home and businesses o Low cost due to fibre and CO interface shared by several customers o Maintenance cost reduction due to no electronics between CO and customers o Multiple applications including data (IP), video and voice (triple play) I TU-T W orkshop “NGN and its Transport Netw orks“ Kobe, 2 0 -2 1 April 2 0 0 6 3
Highlights from Presentation 3 “Cable TV” ITU-T o Distribution of High Definition TV(HDTV) is a key application for broadband access networks —Cable TV system (traditional type, HFC is typical) —FTTH - high speed IP (Video distribution using TDM, Ethernet technology) o Critical issues in Home Networking and Transport —Domain control and Digital Rights Management (DRM) —Quality of Services (QoS) definition I TU-T W orkshop “NGN and its Transport Netw orks“ Kobe, 2 0 -2 1 April 2 0 0 6 4
Highlights from Presentation 4 “W iMAX” ITU-T o Field trials have indicated its feasibility and identified further study items o Global harmonisation required to promote it as global standard (i.e., such as equipment/ system interoperability, common frequency band allocation, etc.) I TU-T W orkshop “NGN and its Transport Netw orks“ Kobe, 2 0 -2 1 April 2 0 0 6 5
CONCLUSI ONS ITU-T o Distribution of High Definition TV(HDTV) is a key applicat ion for broadband access net works o Increase PON bandwidth by using higher transmission rate or WDM technology o Increase PON reach by using optical amplifier o Higher PON splitter ratio (more users per PON) by using optical amplifier I TU-T W orkshop “NGN and its Transport Netw orks“ Kobe, 2 0 -2 1 April 2 0 0 6 6
CONCLUSI ONS ITU-T o Critical issues for Home Networking and Transport —Domain control and Digital Rights Management (DRM) —Quality of Services (QoS) definition o Global harmonisation of WiMAX required to promote it as a global standard o Polymer Optical Fibre (POF) solution for Home Networking?
