The FCC coordinates domestic and international communications by controlling radio, television, telecommunications, satellite, and cable. Involving more than 50 states in the United States, Columbia and the territories of the United States, in order to ensure the safety of radio and wire communication products related to life and property, the Engineering Technology Department of the FCC is responsible for the technical support of the committee and is also responsible for equipment approval. FCC approval is required for many radio application products, communication products and digital products to enter the US market.

FCC is divided into two different certification methods for the types of electronic products, namely: FCC SDoC and FCC ID (Certification). The former is suitable for ordinary products without wireless functions, and the latter is suitable for products with wireless functions.
