Summary

Wireless LAN Convergence 통신망 서비스에서 최종단 접속 기술로 사용증가 전망 무선 LAN 이 별도의 통신 서비스로 지속 되지는 않을 전망이며 ,

convergence 통신망의 종단 접속망으로 활용되어질 전망 PC, Notebook, PDA, Phone, PMP 등 다양한 단말기에 기본장착 될전망이며 , 이는 단말사의 고객 다원화 혹은 통신화를 통한 이용자 증대 목적에 부합 . 통신사의 입장에서는 무선 LAN 은 단순한 기술로 사용하는 것이 바람직하며 ,

이를 위해서는 인증 , 과금 , 보안 등의 intelligence 기능은 통신망과 단말기에 위치하는것이 바람직

Convergence Network

초고속망은 신인증 시스템으로 전화하여 , intelligence 기능을 망내 위치하고 있으면 , 이를 통하여 access 망의 유무선 구분없이 선인증 , 후접속

BcN 의 최종 접속망으로 Wireless LAN 적용시 다양한 단말및 서비스 추가가능

표준화 무선 LAN 자체에 대한 연구보다는 , 전체적인 망구조 표준과 사업모델에

기반한 무선 LAN 활용 연구가 필요


감사합니다 .
