LTE는 지속적으로 발전하고 있습니다. Release 10(LTE-Advanced)에서는 주요한 기능 향상으로 CA(Carrier Aggregation)를 소개했으며, Release 11 및 12는 LTE에 이 외의 여러 가지 새로운 구성 요소들을 추가했습니다. 일부 확장 요소들은 기존 기능을 향상(예: CA 기능의 확장)한 것이며, 또 다른 요소들은 CoMP(Coordinatd Multipoint)와 같이 완전히 새로운 개념입니다.이 애플리케이션 노트에서는 벡터 신호 발생기, 신호 및 스펙트럼 분석기, 광대역 무선 통신 테스터를 이용하는 Release 11 및 12에 따른 LTE-Advanced의 로데슈바르즈 테스트 솔루션에 대해 요약합니다.
