31. Vision of Next Generation User
- Bandwidth is always not enough Application
immediately exhaust - No more take care about Business Providers
Fixed/Mobile/Broadcasting etc. - Cheaper is always better, but Better quality
gets appreciate - Public services are important, but Private
services are also requested

9BB Access Phase 2 Wireless BB could involve
- Wireless broadband needs Higher Speed, Mobility
more Coverage - Services Location-based service, GPS, Streaming
video/audio, On-line game, Internet broadcasting,
- 2.3GHz Portable Internet
- Terminal mobility (over 50km/h)
- Coverage 400500m(dense), 35km(suburban)
- Speed 12Mbps
- ? mainly for Outdoors
- Wireless LAN (Nespot)
- Speed 11Mbps ? 54Mbps
- 2.4GHz(IEEE802.11g), 5GHz(IEEE802.11a)

17Draft 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
18Draft Summary of Broadband Access Group
Contd (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
