Certification introduction
Telecommunication terminal equipment that wants to access the public telecommunications network needs to apply for a network access license. The "network access license" for communication products is commonly called "CTA" in the industry. According to the current laws and regulations of our country, the state implements a network access permission system for telecommunications terminal equipment, radio communication equipment and telecommunications equipment that are used to access public telecommunications networks (mobile, China Unicom, and telecommunications). Telecommunications equipment that implements a network access licensing system must obtain a network access license issued by the Ministry of Information Industry; those who have not obtained a network access license may not access the public telecommunications network for use and sell in the country.
SRRC is the mandatory certification requirement of the National Radio Regulatory Commission, which is what we often say about model approval. CTA is the mandatory requirement of the Telecommunications Equipment Administration of the Ministry of Industry and Information Technology for communications products. The CTA needs to obtain the SRRC certificate before issuing the certificate. To put it simply, these two parallel lines will eventually intersect.
Network license, the state implements a network access license system for telecommunications terminal equipment, radio communication equipment and telecommunications equipment involved in the interconnection of public telecommunications networks. Telecommunications equipment that implements a network access license system must obtain a network access license issued by the Ministry of Information Industry; those who have not obtained a network access license may not access the public telecommunications network for use and sell in the country. The network access license certificate includes the certificate number, applicant, manufacturer, equipment name, equipment model, place of origin, remarks, certificate issuance date, and certificate limited date. The network access license is generally valid for 3 years.

CTA certification requires application materials
