It describes the trend of Internet of Things,analyzes application demand and development prospect of Internet of Things based on cel ular network. According to the service features and market developing requirements,3GPP devotes lots of efforts to the key technologies research and standardization work on both several candidate narrow-band Internet of Things solutions and new features of 3G and 4G technologies. The further researches of the operator side should focus on the network evolution and deployment strategies,including spectrum,key technologies,roadmaps,and other critical issues. Confronted with the furious competition of the market,operators also need to accelerate the research progress and commercial deployment of In-ternet of Things.
