17. Draft Summary of Broadband Access Group (Future works on Broadband Access) Vision of Broadband Access • BB Access provides potential to bridge the economic and social gaps : TSACC • - Improving Health Care, Making New Learning Opportunities etc. • - Universal and fare opportunity to access Multimedia services for everyone • Features of BB Access technologies : ETSI, TTA • - Diversity of Access Technology will give more freedom to Users & encourage Business • - Services could have independency from under line access technologies • - Features : Interoperability, QoS, Emergency cap., Security, Lawful interception etc. • BB Access would take a triggering role to initiate Fixed and Mobile convergence : TTA • - Provide more flexibility to the user selecting service providers (mainly focus services) • - Initial challenge for preparation of convergence world GSC-9, Seoul

18. Draft Summary of Broadband Access Group : Cont’d (Future works on Broadband Access) Broadband Access with Satellite : TSACC • Satellite could be one of key infrastructure to cover BB Access requirements • Very critical for covering rural areas and providing emergency services • Continuous efforts are going on economic use of satellites for individual • (ease of use Ka-Band, Economical Systems includes User Terminals etc.) Broadband Access in Terrestrial • Wireless Broadband Access : TTA, TSACC, ETSI • - One of the best way to cover rural areas combining with satellite • - Extending network capabilities of WLAN, WMAN and other Wireless BB technologies • - Special notes to BRAN (ETSI) and IEEE 802 activities : need study Public OAM aspects • Wire Broadband Access : TTA, ATIS • - Final target could be Optics such FTTH. Time to realize, not any more in the paper • - Need development of L2 technologies to utilize Optics economic way • - Continuous development of technologies to maximize current fixed infrastructure • * VDSL, VDSL 2, ADSL 2 plus, SHDSL, M2DSL etc. • * Enhancement of and develop Dynamic Spectrum Management GSC-9, Seoul
