FCC certification introduction
The FCC (Federal Communications Commission) was established by COMMUNICATIONACT in 1934 as an independent agency of the US government and is directly responsible to Congress. The FCC coordinates domestic and international communications by controlling radio, television, telecommunications, satellites and cables. Involving more than 50 states, Columbia, and the United States, in order to ensure the safety of radio and wire communication products related to life and property, the FCC ’s Office of Engineering and Technology is responsible for the technical support of the committee and is responsible for the equipment Recognition matters. Many radio application products, communication products, and digital products require FCC approval to enter the US market.
