What does NB-IoT wireless data terminal mean?IoT Internet of Things
NB-IoT wireless data terminal refers to an Internet of Things connected device based on cellular network, which uses narrowband Internet of Things (NB-IoT) technology to realize remote management and monitoring of Internet of Things devices through wireless communication. The terminal has the characteristics of low power consumption, wide coverage, large connection, low cost, etc., and is suitable for smart meter reading, smart parking, smart fire protection and other fields.
The core technology of the NB-IoT wireless data terminal is narrowband Internet of Things (NB-IoT) technology. This technology is a new type of wireless communication technology that can achieve efficient communication in a narrow frequency band, and is suitable for application scenarios that require low power consumption and wide coverage. Compared with traditional wireless communication technologies, NB-IoT technology has the advantages of lower power consumption, wider coverage, larger number of connections, and lower cost.
NB-IoT wireless data terminals have a wide range of applications in the fields of smart parking, smart fire protection, etc. In the field of intelligent meter reading, the terminal can remotely monitor the user's water, electricity, gas and other conditions to improve the efficiency and accuracy of meter readingIn the field of smart parking, the terminal can realize automatic monitoring and reservation of parking spaces, which is convenient for users to find parking spaces and pay parking feesIn the field of intelligent fire protection, the terminal can monitor the operation status and fire situation of fire protection facilities in real time, issue alarms in time and link the emergency treatment system.
What certification should be done for the NB-IoT wireless data terminal to be sold on the market?
NB-IoT wireless data terminals are sold in China and need to go through a series of certification procedures to ensure the quality and safety of the products. Among them, one of the most important certifications is Chinese3C certification
3C certification is a compulsory product certification system implemented by China to protect the interests of consumers. This certification is mainly for electrical products, including household appliances, auto parts, electronic products, etc. For NB-IoT wireless data terminals, because they involve wireless communication and data processing, they also belong to the scope of 3C certification.
When applying for 3C certification, the manufacturer of the NB-IoT wireless data terminal needs to submit application materials to China**, including product samples, technical documents, quality management system documents, etc. China** will review the application materials and test and inspect the products to ensure that they comply with the relevant standards and regulations in China.
In addition to 3C certification, NB-IoT wireless data terminals also need to undergo other relevant certifications, such as:Radio Emission Type Approval Certification and Telecommunications Equipment Network Access LicenseWait. These certifications are also to ensure that the performance and quality of the products comply with Chinese standards and regulations.
In addition, in order to sell NB-IoT wireless data terminals in the Chinese market, manufacturers also need to comply with relevant Chinese laws, regulations and standards, such as the Cybersecurity Law of the People's Republic of China and the Personal Information Protection of the People's Republic of China**. At the same time, it is also necessary to cooperate with operators such as China Mobile and China Unicom to ensure that the terminals can be compatible with China's communication network and be widely used.
In conclusion, the NB-IoT wireless data terminal is sold in China and needs to go through a series of certification procedures to ensure the quality and safety of the product. Manufacturers need to comply with relevant laws, regulations and standards in China, and cooperate with operators in China to achieve a wide range of terminal applications in the Chinese market.
