최근 iPhone과 iPad의 돌풍으로 스마트폰 및 태블릿 등의 모바일 단말이 급속도로 확산되면서 무선 데이터 트래픽 폭증이 기존 네트워크 아키텍처로는 한계점에 도달하게 되었다. 무선 데이터 사용자의 증가에 따라 네트워크의 용량 증설이 필요하게 되었으며, 이는 상당한 양의 투자비용과 운용비용을 초래하고 있다. 이러한 문제점을 해결하기 위한 방안으로는 무선 데이터 트래픽 폭증 시대에 유력한 대안으로 급부상한 클라우드 기반의 기지국 아키텍처이다. 본 고에서는 KT의 CCC 솔루션과 알카텔루슨트의 lightRadio의 클라우드 기반의 기지국 아키텍처, 클라우드 기반의 기지국 국내외 최근 동향, 그리고 향후 전망에 대해 기술하였다.
