M2M(Machine to Machine

메시 네트워크 (Mesh Network)는 특수 목적을 위한 네트워크이다.

M2M은 전기, 가스 등의 원격 검침에만 사용된다.

Wi-SUN 스마트 그리드는 저전력 장거리 통신 기술이다.

UWB는 블루투스와 비교되는 무선 기술이다.

피코넷은 블루투스와 UWB 통신 기술을 사용하여 통신망을 형성하는 무선 네트워크 기술이다.

RFID 태그는 사물의 인식 정보뿐만 아니라 주변의 환경정보까지 탐지할 수 있다.

SON(Self Organizing Network)은 갑작스러운 사용자의 증가나 감소 시에는 자동으로 주변 셀과의 협력을 통해 셀 용량을 변화시키며, 장애가 발생했을 때 자체적인 치유도 가능하다.

저전력 블루투스 기술(BLE)은 낮은 전력으로 저용량 데이터를 처리하는 사물 인터넷에 적합하다.
