삼성전자와 한국전자통신연구원이 공동으로 기술개발에 성공하여 2006년 6월 국내에서 세계 최초로 서비스를 개시한 WiBro는 최대 전송속도 하향 75Mbps(2×2 MIMO)/상향 50Mbps(1×n MIMO), 시속 250km/h로 이동하면서 사용할 수 있는 기술이다. 2011년 1분기 기준 전세계 90개국195개 사업자가 WiBro 서비스를 제공 또는 준비 중인데, 최근 대규모 WiBro 사업자인 러시아 Yota와 미국 Clearwire가 LTE로의 전환 가능성을 시사하는 등 글로벌 WiBro 사업에 대한 위기감이 나타나고 있다. 본 고에서는 국내외의 WiBro의 시장 현황 및 전망을 살펴보고, 국내로의 시사점을 모색해보고자 한다.
