1. 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

BB 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
Wireless LAN (Nespot)
• Speed : 11Mbps  54Mbps
• Terminal mobility (over 50km/h)
• 2.4GHz(IEEE802.11g),
5GHz(IEEE802.11a)
• Coverage : 400~500m(dense),
3~5km(suburban)

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

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
