9.11 테러 이후의 비상통신에 대한 관심이 증대되었고, 경찰, 소방, 응급구조 활동 등 공공안전 및 긴급 구조 대응(PPDR)을 위한 활동 조직의 범위가 확대되고 있으나, 원활한 구조활동 수행을 위한 인프라 구축이 현재로서 부족한 상황이며, 자연 재해 및 인위적 재해에 대해 반응하기 위한 음성, 데이터, 이미지, 동영상 등의 재난통신의 동시 수행능력이 미비한 상황이다. 이에 따라, 공공안전 및 긴급 구조(PPDR) 활동을 수행하는 전문가들 간의 통신수단을 효과적으로 상호 운용하기 위해 고도화된 통신 인프라 구축의 필요성이 제고되고 있으며, 유럽과 북미 간의 공공 안전 분야의 무선통신에 관한 표준활동인 MESA 프로젝트가 등장하게 되었다. 본 고에서는 MESA 프로젝트의 활동분야 및 수행 활동 동향에 대해서 살펴보고자 한다.
