Abstract: NB-IoT is an IoT communication technology based on 3G/4G evolution of cellular communication. It works in a dedicated licensed frequency band. mainly used for low-throughput and massive connection scenarios and will undertake a large number of IoT access services in the future. Therefore, NB-IoT will be one of the main communication technologies for intelligent transformation and upgrading of white household appliances. Using the characteristics of wide-area coverage, it is possible to track home appliance location in the warehouse's inbound and outbound management, pre-sale logistics and user area distribution statistics by equipping with battery power supply, and to carry out more efficient and convenient supply chain management. Due to the convenient access of NB-IoT and the high network access rate, users can make maximum use of their home appliance usage data and fault data to achieve targeted sub-regional customized development and marketing activities.
