유한한 자원인 스펙트럼을 효율적으로 사용하고자 화이트 스페이스를 이용할 수 있는 방안에 대한 연구가 진행되고 있다. 화이트 스페이스를 활용하려면 장치가 스펙트럼 정보를 파악할 수 있어야 한다. 이를 위한 방법에는 크게 스펙트럼 센싱을 이용한 방법과 스펙트럼 데이터베이스를 이용하는 방법이 있다. 본고에서는 스펙트럼 데이터베이스를 활용하기 위해 필요한 프로토콜의 표준 동향에 대해서 살펴본다. 프로토콜 표준에 대한 이해를 돕기 위하여 표준이 완성되기까지의 개요, 프로토콜 요구사항 및 프로토콜 표준 내용에 대해서 간단하게 알아보고, 대표적인 기능으로써 스펙트럼 요청 기능에 대한 메시지 형태와 주요 파라미터에 대해 살펴본다.
