현재 이동/무선통신 환경은 사람과 사람 간의 통신 서비스 형태뿐만 아니라 IoT 통신 서비스로 점차 확대되어가고 있으며, Wi-Fi, Bluetooth 중심의 근거리 무선통신뿐만 아니라 더욱 통신영역이 좁아진 근접통신의 필요성이 대두되고 있다. 이에 따라 근접통신 기술 개발이 지속적으로 이루어지고 있으며, 특히 기기 간의 대용량 데이터 교환이 증가함에 따라 기가급의 속도를 제공하는 초고속 근접통신 기술들이 활발하게 개발되고 있다. IEEE 802에서는 주변 기기들간의 직접(Point-to-Point: P2P) 통신을 지원하는 802.15.3e 초고속 근접통신 기술을 개발하고 있으며, 또한, 802.11ad의 후속 표준으로 개발이 시작된 802.11ay의 Usage Model에도 근접통신이 포함되어 있다. 본고에서는 이러한 초고속 근접통신 기술동향에 대해 기술하고자 한다.
