In the United States, wireless equipment authorization is a critical step for manufacturers and developers to legally market their products. The Federal Communications Commission (FCC) oversees this process to ensure that all electronic devices comply with the necessary regulations to avoid harmful interference and to ensure safety. Below are the steps required to obtain wireless equipment authorization, the types of devices that need FCC authorization, and the methods of obtaining such authorization, including Supplier’s Declaration of Conformity (SDoC) and FCC Certification.
Types of Devices Requiring FCC Equipment Authorization
Any electronic device that emits radio frequency (RF) energy and is intended for use in the United States needs to comply with FCC regulations. These devices include, but are not limited to:
- Wireless routers
- Mobile phones
- Bluetooth devices
- Wi-Fi enabled devices
- RF remote controls
- Radio transmitters
- Satellite communication devices
Essentially, if your device intentionally radiates RF energy, it likely needs FCC equipment authorization.
Methods of Obtaining FCC Equipment Authorization
There are two primary methods for obtaining FCC equipment authorization: Supplier’s Declaration of Conformity (SDoC) and FCC Certification. Both processes ensure that the devices comply with the applicable FCC rules, but they differ in their procedures and requirements.
Supplier’s Declaration of Conformity (SDoC)
The SDoC process is typically used for devices that are not considered to have a high potential for causing harmful interference, typically unintentional radiators. This could also be used if the radio modules used by the device are already FCC certified. This method involves the following steps:
- Testing: The device must be tested to ensure it complies with the FCC emissions and immunity standards based on the device's intended use. This testing can be done by the manufacturer or a third-party testing facility.
- Documentation: The manufacturer must compile a technical file that includes the test report, product description, and compliance statement.
- Labeling: The device must be labeled with the FCC logo and any other required information.
- Record Keeping: The manufacturer must keep the compliance documentation and be able to provide it to the FCC upon request. See 47 CFR § 2.938.
FCC Certification
FCC Certification is required for devices with higher risk of causing interference, such as intentional radiators (e.g., transmitters). The certification process is more rigorous and involves the following steps:
- Testing: The device must be tested by an FCC-recognized accredited testing laboratory.
- Filing: The test results, along with the necessary technical documentation, must be submitted to a Telecommunication Certification Body (TCB) for review.
- Grant of Equipment Authorization: If the TCB determines that the device meets all FCC requirements, it issues a grant of equipment authorization, and the device is assigned an FCC ID.
- Labeling: The device must be labeled with the assigned FCC ID and other required information.
- Post-Market Surveillance: The FCC or the TCB may conduct post-market surveillance to ensure continued compliance.
Comparing SDoC and FCC Certification
| Aspect | SDoC | FCC Certification |
|---|---|---|
| Complexity | Simplified, less rigorous | More rigorous and detailed |
| Testing | Can be done by manufacturer or third party | Must be done by FCC-recognized lab |
| Approval | Self-declaration | Requires review and approval by TCB |
| Labeling | FCC logo and compliance statement | FCC ID and additional labeling requirements |
| Applicability | Low-risk devices | High-risk devices, especially intentional radiators |
| Record Keeping | Manufacturer keeps records | Records kept and managed by TCB |
FCC Part 15
FCC Part 15 covers unlicensed transmissions and sets forth the regulations for devices that emit RF energy without requiring a specific license. It includes rules for:
- Intentional Radiators: Devices that intentionally emit RF energy, such as Cellular/ Wi-Fi routers and Bluetooth devices. See 47 CFR Subpart C.
- Unintentional Radiators: Devices that may emit RF energy as a byproduct of their operation, such as computers and other electronic devices. See 47 CFR Subpart B.
Compliance with Part 15 ensures that devices do not cause harmful interference and must accept any interference received.
47 CFR § 15.101 provides examples of unintentional radiators that can use SDoC procedure for authorization and those that must use FCC certification:
| Unintentional Radiator | Can Use SDOC for Equipment Authorization? |
| TV Broadcast Receiver | Yes |
| FM Broadcast Receiver | Yes |
| CB Receiver | Yes |
| Superregenerative Receiver | Yes |
| Scanning Receiver | No |
| Radar Detector | No |
| All other receivers subject to Part 15 | Yes |
| TV Interface Device | Yes |
| Cable System Terminal Device | Yes |
| Stand-alone Cable input selector switch | Yes |
| Class B personal computers and peripherals | Yes |
| CPU boards and internal power supplies used with Class B personal computers | Yes |
| Class B personal computers assembled using authorized CPU boards or power supplies | Yes |
| Class B external switching power supplies | Yes |
| Other Class B digital devices & peripherals | Yes |
| Class A digital devices, peripherals & external switching power supplies | Yes |
| Access Broadband over Power Line (Access BPL) | No |
