In today's fast-paced world, reliable and high-speed wireless connectivity is essential.  Wi-Fi 6E is a cutting-edge wireless technology that is revolutionizing the way we connect. However, with great power comes great responsibility, particularly when it comes to regulatory compliance. It is important to understand the two phases of Wi-Fi 6E certification, and the limitations of where Wi-Fi 6E devices can operate per FCC standard.

Wi-Fi 6E U-NII band frequency Allotment
Wi-Fi 6E harnesses the untapped potential of the 6 GHz frequency band, delivering unparalleled speed, capacity, and reliability. On April 23rd, 2020, the FCC (Federal Communication Commission) has voted to open 1,200 MHz of spectrum of Unlicensed use, as follows: 

However, this newfound spectrum requires adherence to regulatory guidelines to ensure interference-free operation and coexistence with other wireless services. We delve into the key regulatory considerations and challenges that accompany Wi-Fi 6E deployment, paving the way for a seamless wireless future. 

Certification Guidance
To navigate the complex regulatory framework, manufacturers and developers must familiarize themselves with the specific compliance requirements governing Wi-Fi 6E. This section provides an overview of the regulatory bodies, standards, and certifications relevant to Wi-Fi 6E deployment, shedding light on the intricate web of compliance obligations.

The FCC has rolled out the Certification guidance for Wi-Fi 6E Certification in two phases, Phase 1 and Phase 2. Certification for Phase 1 devices is now being accepted. Certification for Phase 2 devices is not available at this time and is dependent on when the Automated Frequency Coordination (AFC) system is finalized and approved.

The devices included in Phase 1 are Indoor Devices, and are listed below along with the associated (new) Equipment Classes (applicable to a Form-731). 

Phase 1: Indoor Devices operating in the 5.925-7.125 GHz band
•    6ID: 6 GHz Low-power indoor access point.  
•    6PP: 6 GHz Subordinate indoor device.
•    6XD: 6 GHz Low-power Indoor client.
•    6CD¹: 6 GHz Dual Client (these client devices can connect to Standard Power access points as well as Low Power indoor access points).

Phase 2: Standard Power Access Points and Associated Client Devices – Database Managed Using Automated Frequency Coordination (AFC)
•    6SD*: 15E 6 GHz Standard power access point.
•    6FX*: 15E 6 GHz Standard client.
•    6FC*: 15E 6 GHz Fixed client.
•    6CD¹: 6 GHz Dual Client (these client devices can connect to Standard Power access points as well as Low Power indoor access points).

* Applications only accepted in Phase 2.

Testing and Certification Requirements
While the underlying FCC Rule Part remains unchanged for 5 GHz Wi-Fi devices, there are additional distinct requirements for devices operating in 6 GHz outlined by the FCC, such as the slight deviation in the measurement methods. 

For more information regarding all requirements for above equipment classes can be found in the Part 15 Subpart E §15.407 standard section 4 - 10 and in FCC's Office of Engineering and Technology under KDB 987594. The rules and guidance respectively linked below:

•    Title 47, Chapter I, Subchapter A, Part 15, Subpart E, §15.407
•    Office of Engineering and Technology KDB 987594
