최근에는 UWB 기기들이 단순한 RF Tx, Rx 측정뿐만 아니라 ToF(Time of Flight)와 AoA(Angle of Arrival) 항목에 대한 측정도 지원해야 하는 추세입니다. ToF는 신호가 발신지에서 수신지까지 도달하는 데 걸리는 시간을 의미하며, AoA는 도착하는 신호의 방향을 말합니다. 이러한 요구 사항에 맞춰, Rohde & Schwarz는 UWB의 모든 항목들에 대한 Calibration 및 Verification을 지원하고 있습니다. 이번 웹세미나를 통해 UWB 기술에 대한 이해를 높이고, 최신 측정 방법도 확인하실 수 있습니다.
