FCC Wi-Fi 6E VLP device certification requirements
The FCC proposed to implement very low power (VLP) devices in the Wi-Fi 6E band at the end of September last year, and updated § 15.407 in early March this year, adding relevant requirements for VLP devices; then the FCC updated and released the draft version of KDB 987594 in early April this year, mainly adding content related to VLP devices.
1. Device category:
Before the release of the new KDB, FCC Wi-Fi 6E supported a total of 7 device categories, such as low power indoor access point 6ID: Low Power Indoor Access Point, indoor client 6XD: Indoor Clients.
For the newly added VLP device, its device category is defined as 6VL, and its connection relationship is as follows
P1: Clients, slave devices, and VLP devices are controlled by low power indoor access points.
P2: Clients and VLP devices are controlled by standard power access points.
P3: Standard power access points and fixed client devices are managed by AFC.
P4: VLP devices communicating with other VLP devices are not controlled by standard power or low power indoor access points.
VLP devices can not only connect to APs, but also specifically allow them to communicate directly with other VLP devices. This method is conducive to achieving lower latency communication and improving the convenience of effective use of frequencies, and is more suitable for the following usage scenarios:
- Sharing screens with each other in games.
- Mirroring to TV monitors.
- Game controllers (handles).
- AR/VR devices.
- Exchanging security keys between devices.
2. Technical requirements
As shown in the figure below:

In addition to the regular certification requirements (such as Label, FCC ID, etc.), for the above technical requirements, additional attention should be paid to the following certification matters:
1. The user manual must contain the following information:
- It is prohibited to operate the device on oil platforms and aircraft, but it is allowed to operate the device at 5.925-6.425 GHz on large aircraft flying above 10,000 feet.
- Installation on outdoor fixed infrastructure is prohibited.
2. Device protocol certification statement to be submitted during the certification process:
- State that the device will give priority to spectrum above 6.105 GHz (provide details on how to implement it).
- State that the device will use transmit power control (TPC). Provide details on the mechanism that triggers TPC (e.g., environment, performance, bandwidth, etc.).
3. Statement to confirm device restrictions to be submitted during the certification process:
- Operation of the device on oil platforms and aircraft is prohibited, but operation of the device at 5.925-6.425 GHz on large aircraft flying above 10,000 feet is allowed.
3. Test items:
The most important thing about FCC Wi-Fi 6E VLP device certification is the test report.
Most of the test items and requirements are the same as other Wi-Fi 6E device categories. The power and PSD requirements of VLP devices are very strict, and there is a special requirement, namely TPC. This test item requires the manufacturer to assist in providing a method to trigger this function for testing. The above content is based on the currently public draft version KDB 987594. If manufacturers plan to produce Wi-Fi 6E VLP devices and want to ship them to the United States, they can refer to the above content to make preparations in advance. After the FCC KDB releases the official version, they can start the certification.
