Abstract: 간섭을 최소화하는 것을 지원하기 위해서, 대역폭 범위는 이웃 대역폭 범위들로의 누설을 감소시키도록 양 측면에 가드들을 가질 수 있다.  그러나 상대적으로 낮은 전력 상황에서 누설 위험은 감소된다.  따라서, 정보가 전송될 수 있는 새로운 채널들을 개방하기 위해서 가드 대역폭들이 이용될 수 있다.  따라서, 이웃 대역들로의 낮은 간섭과 같은 보호 양상들을 유지하면서, 사용되는 대역폭 양을 증가시킬 수 있다.  새로운 채널들을 전송하기 위해서 가드 대역폭을 사용하는 것은 역방향 호환성을 달성할 수 있는데, 왜냐하면 레거시 장치들이 가드 대역폭을 일반적으로 모니터링하지 않기 때문이다.  이러한 기술들은 또한 필요한 것보다 큰 가드를 레거시 장치들에게 광고하고 추가적으로 생성된 가드 대역폭을 새로운 채널들을 전송하는데 사용함으로써 고전력 기지국들에서 또한 사용될 수 있다.
