For suburban areas and some covered areas, NB-IoT can greatly enhance the high value-added agricultural production and circulation fields such as aquaculture, greenhouses and flowers.
13 Does smart manufacturing favor NB-IoT?
At present, the wireless signal coverage of many large-scale factories is very poor. The implementation of wired communication is difficult or the cost is too high. To achieve the goal of intelligent manufacturing, it is necessary to ensure that IOT communication is carried out by key equipment and instrumentation.
NB-IoT's network coverage capability, combined with the plant's fiber network, broadband network, etc., to create a simple and effective full-network coverage capability, which is the basis for intelligent manufacturing.
