Its low power consumption, low cost, low tariff, strong coverage, large capacity and other features can be recognized and matched by various application scenarios. Since China Telecom announced its official commercialization in July 2017, nearly 10,000 NB base stations have been deployed nationwide, and network coverage is perfect. In the fields of public utilities (four meters), smart cities, equipment management, agriculture and environment, smart logistics, intelligent buildings, cultural relics protection, medical care, automation industry, consumer and other fields, there have been a large number of pilots and mass commercial applications.

This module can quickly access the NB network for products and connect to the cloud. The product development cycle is greatly shortened and the design difficulty is reduced, and communication stability is strongly guaranteed.
