1, IoT communication protocols: mainly to solve the networking of devices, interconnectivity, secure transmission, etc., including CoAP, MQTT, NB-IOT, LORA, sigfox and other protocols.

2. Edge computing: mainly solves the marginalization of device management and data analysis and aggregation, and mainly solves the future impact of massive device networking on bandwidth, the requirements of transmission delay, and the requirements of data privacy protection.

3, fog computing: edge of each IoT device computing nodes cooperate with each other to complete complex computing tasks. Solve problems such as reuse of device resources.

4, big data: analyze the data analysis of massive devices to support rapid and accurate decision-making.

5, artificial intelligence: comprehensive use of data generated by the device, the application of artificial intelligence technology, resulting in a number of intelligent applications, so that the value of the Internet of Things to give full play to. The ultimate goal of the Internet of Things is intelligence, and the realization of a large number of intelligent applications depends on the Internet of Things.
