차세대 이동통신에 의한 새로운 정보통신 환경 실현은 21세기의 산업구조에도 막대한 영향을 주어서 대변혁을 가져올 것이다. 4세대 이동통신의 실현에 의한 정보통신환경의 Broadband화, Ubiquitous화, Mobile & Wireless화에 의해 주요한 산업으로 크게 확대되고, 융합 ‧ 발전할 것으로 기대되고 있다. IMT-Advanced 이동통신 기술은 고속이동 환경에서 최대 100Mbps, 고정 또는 저속이동 환경에서 최대 1Gbps의 데이터 전송속도로 비대칭/대칭적 패킷 서비스와 방송 서비스를 포함한 다양한 서비스를 IP 기반으로 통합 제공하는 기술을 의미하며, IMT-Advanced 시스템뿐만 아니라 다양한 무선통신 시스템과 통합되는 형태로 실현될 것으로 예상된다. 본 고에서는 차세대 이동통신기술 동향과 국내외 개발 동향, 표준화 동향 등을 간략히 살펴보고자 한다. 특히, 차세대 이동통신 기술은 셀룰러 이동통신, 차세대 WLAN, 차세대 WPAN, SDR 등을 중심으로 살펴보고자 한다.
