자율주행차량을 위해 기존에는 상용 WiFi, Bluetooth, ZigBee, WiMax, IEEE 802.11p 기반 근거리 전용 통신(Dedicated Short Range Communication: DSRC) 및 4G를 차량에 통합하려고 시도했다. 그러나 기존 무선통신 기술은 대역폭이 제한되어 있어 자율주행차량 통신에서 차량 센서 시스템의 3차원 및 고화질 영상과 같은 대용량의 데이터를 지연 없이 처리하기에는 어려운 문제점이 있다. 본 고에서는 자율주행 시 대용량의 데이터를 지연 없이 전달하기 위해서 차세대 밀리미터파 기반 무선통신 기술을 자율주행차량 사물 통신에 적용하여 대용량 트래픽 데이터를 초고속, 초저지연 통신으로 전송할 수 있는 차량 사물 통신 기술에 대해 논하고자 한다.
