Which products need compliance testing and FCC certification?

Any radio frequency device sold or distributed in the USA must have FCC certifications.

Generally, the products that need FCC certification are divided into two classes:

Class A: Intentional radiators of radiofrequency: These are products that must broadcast radiofrequency energy while in operation

Class B: Unintentional radiations: These products have the potential to create and broadcast radio signals as a by-product of their operation
