초록

WLAN 및 이동통신은 계속해서 많은 서로 다른 표준으로 진화함에 따라 이동통신 사업자는 기술적 경제적 많은 어려움에 직면하고 있다. 따라서 끊임없는 시스템 업그레이드가 필요하게 된다. 이러한 문제를 해결하기 위한 새로운 접근 방법을 모색하여 그 타당성을 연구하였다. 즉, electro-absorption modulator(EAM) 과 optical single sideband (OSSB)에 기반한 radio over fiber (RoF) 기술을 사용해 저가, 단순, 주파수변화 및 프로토콜 변화가 없는 트랜스패런트한 무선 액세스 망을 구축하여 그 해결책을 제시하였다. 본 논문에서는 프로토타입 CATV 용 60GHz 대 무선 RoF 분배시스템을 구축하여 broadband convergence network (BcN)의 무선 액세스망에 사용가능성을 타진하였다.

Mobile operators will face many challenges both economically and technically, as WLAN evolve through a bewildering number of different standards during the coming years. Potentially this will require several upgrades to the mobile infrastructure. A new approach for addressing these challenges is evaluated in this paper. It is based on a radio over fiber (RoF) technology that uses electro-absorption modulator (EAM) and optical single sideband (OSSB) modulation technique and it promises to provide solutions that will be transparent to changes in protocols and frequency of operation as well as reducing radio access infrastructure costs. This paper describes the development of prototype RoF system based on the 60GHz band CATV transport distribution system with EAM and the possibility of radio over fiber technology for use in the broadband convergence network (BcN) wireless access infrastructure.
