Any electronic device marketed or sold in the US must have Federal Communications Commission (FCC) approval. How can suppliers of electronic devices to US markets ensure compliance in their products?
The FCC regulates electronic equipment to protect consumers and prevent radio frequency (RF) interference between digital devices by setting specific limits on the intentional and unintentional radio signals a device can emit. The limits set for devices that do not intentionally transmit radio signals are related to the environment in which the device is used.
These are:
Class B has stricter requirements due to a greater risk of RF emissions from products that are used in the home.
Depending on whether the device intentionally or unintentionally radiates radio signals, there are two routes to approval for manufacturers and suppliers:
If the product intentionally radiates radio signals, it will require certification. Examples of devices falling into this category include Wi-Fi routers, Bluetooth devices, remote control transmitters and garage door openers.
If the device is an unintentional radiator, it can be authorized either via certification or SDoC. Examples in this category include IT equipment, audio-visual devices and power adapters.
To ensure an electronic device complies with FCC regulations for RF emissions, the manufacturer or supplier must submit it to an electromagnetic compatibility (EMC) testing laboratory for evaluation. If the device is to be authorized by SDoC, then no further action is required. However, if the product is to be authorized via certification, the following documents and information must be submitted to a Telecommunications Certification Body (TCB):
A Grant of Equipment Authorization (FCC Grant) will then be issued, allowing the product to be legally sold on US markets.
For businesses involved in the manufacture, distribution, marketing and sale of electronics devices, these steps can be stressful, time-consuming and costly to navigate.
EMC testing and RF compliance testing are critical aspects of the development process for any electronic device. EMC testing assesses a device’s ability to operate properly in its intended electromagnetic environment without interfering with other pieces of equipment. RF testing measures the characteristics of the intentionally radiated signal, as well as ensuring unintentionally radiated signals are below regulated limits.
