Internet of Things technology has developed rapidly in the last decade. Sensors are more intelligent, and RFID technology cost performance has been dramatically improved. Emerging wireless communication technologies such as NB-IoT, 5G, Cat.1, and LoRa have emerged. Small wireless communication technologies like Wi-Fi, Bluetooth, and Zigbee have evolved. UWB, AOA, Beidou, and other positioning technologies have been continuously optimized; cloud computing, data centers, operating systems, AI algorithms, and other platform layer technologies and facilities have constantly been improved. Breakthroughs in these underlying technologies have laid a solid foundation for developing the Internet of Things. Finally, enrichment of industry chain participants. The IOTE has been favored by Huawei, Ali, Tencent, the three major operators, Xiaomi, and other giants. Prominent suppliers see IoT as a "new track" to the future. More supporting vendors and entrepreneurs are pouring into IoT, and the type and number of industry participants are expanding abundantly. IOTE gathers core technologies, from technological innovation, hardware procurement, and system integration, to the whole industrial chain of the IoT, witnessing the birth and development of the IoT industry in China, and will continue the ecological integration, industrial cooperation, and application of the IoT industry!
