17. GSC-9, Seoul 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

18. GSC-9, Seoul Broadband Access with Satellite : TSACC Broadband Access in Terrestrial 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.) 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, M 2 DSL etc. * Enhancement of and develop Dynamic Spectrum Management Draft Summary of Broadband Access Group : Cont’d (Future works on Broadband Access)
