As next-generation wireless technologies like Wi-Fi 6/6E (802.11ax), Wi-Fi 7 (802.11be), and upcoming Wi-Fi 8 (802.11bn) roll out, ensuring FCC compliance is more critical than ever for U.S. market entry. The Federal Communications Commission (FCC) enforces strict rules to manage RF emissions, prevent interference, and optimize spectrum use.
Below, we break down key FCC compliance areas for high performance 5GHz and 6GHz bands, making it simple to navigate the regulatory landscape. Note, this article does not cover the frequently used 2.4GHz band.
1. FCC Radio Compliance
| Requirement | Details |
| Certification Type | Under FCC Part 15 (unlicensed devices) |
| Test Labs | Must be FCC Recognized |
| Purpose | Validate compliance with emission limits and technical radio requirements |
2. UNII Band List
UNII stands for Unlicensed National Information Infrastructure. It’s a set of radio frequency bands in the 5-7 GHz range designated by the FCC (Federal Communications Commission) in the United States for unlicensed wireless communications.
| UNII Band | Frequency Range (GHz) | Operation Type |
| U-NII-1 | 5.150 – 5.250 | Indoor, Low Power Outdoor allowed with specific antenna EIRP elevation requirement |
| U-NII-2A | 5.250 – 5.350 | Indoor – This band is primarily reserved for radar use, but Wi-Fi operation is allowed if Dynamic Frequency Selection (DFS) testing is implemented. |
| U-NII-2C (Extended) | 5.470 – 5.725 | Indoor/Outdoor – This band is primarily reserved for radar use, but Wi-Fi operation is allowed if Dynamic Frequency Selection (DFS) testing is implemented. |
| U-NII-3 | 5.725 – 5.850 | Outdoor/Indoor |
| U-NII-4 | 5.850 – 5.925 | Limited/Conditional Use |
| U-NII-5 | 5.925 – 6.425 | Standard Power (AFC) & Low Power Indoor |
| U-NII-6 | 6.425 – 6.525 | Low Power Indoor only |
| U-NII-7 | 6.525 – 6.875 | Standard Power (AFC) & Low Power Indoor |
| U-NII-8 | 6.875 – 7.125 | Standard Power (AFC) |
3. RF Exposure Compliance
| Requirement | Details |
| Exposure Evaluation | Specific Absorption Rate (SAR) Testing or Maximum Permissible Exposure (MPE Report) depending on device application and distance from body during normal use |
4. 6 GHz Specific Spectrum Considerations
| Requirement | Details |
| Pre-Approval Guidance (PAG) | Additional Pre-Approval Guidance may be required from FCC depending on the device type |
| AFC Requirements | Outdoor devices must comply with Automated Frequency Coordination (AFC) protocol |
5. 6GHz Pre-Approval Guidance (PAG)
| Device Type | Requirement |
| U-NII Dual Clients (6CD) | Yes |
| Standard Power Access Points (6SD) | Yes |
| Fixed Clients (6FC) | Yes |
| Standard-Only Clients (6FX) | Yes |
| Very Low Power (VLP) Devices | Yes |
| Low Power Indoor Access Points (6ID) | No |
| Subordinate Devices (6PP) | No |
| Indoor-Only Clients (6XD) | No |
| Indoor-Only Clients (6XD) | No |
