What is CTA certification?

The state implements a network access licensing system for telecommunication terminal equipment, radio communication equipment used in accessing public telecommunications networks, and telecommunications equipment involving inter-network interchange. Telecommunications equipment must obtain a network access license; without a network access license, it may not be connected to a public telecommunications network for use and sold in the country.

Telecommunications equipment access network certification

Network access license, the state implements a network access license system for telecommunications terminal equipment, radio communication equipment and telecommunications equipment that are used to access 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.
