Wi-Fi 6 E Explained
How does Wi-Fi 6E work?
Wi-Fi today uses two bands: 2.4GHz and 5GHz. Wi-Fi 6E utilizes a third band: 6GHz. Wi-Fi 6E extends the same Wi-Fi 6 capabilities into the 6 GHz to allow greater efficiency, higher throughput, and increased security.
Why Wi-Fi 6E?
- More capacity in the 6 GHz band, which solves connection and congestion issues.
- Wider channels, up to 160 MHz, which are ideal for high-def video and virtual reality.
- No interference from microwaves, etc. because only 6E-capable devices can use the band.
What device types support Wi-Fi 6E?
The following illustration shows all Wi-Fi 6E device classes, although not all device classes are supported in all geographical locations.
What device classes support Wi-Fi 6E?
- Standard Power (SP) AP: Supports outdoor and indoor operations, where the Standard Power APs are coordinated through an Automated Frequency Coordination Service (AFC) to mitigate 6Ghz Wi-Fi from interfering with incumbent services such as public safety and cellular backhaul, microwave links, satellite services, and TV broadcast services.
- Low Power Indoor (LPI) AP: This fixed indoor only class uses lower power levels and does not require an AFC. LPI APs for use in indoor enterprise deployment provide the same coverage as today’s Wi-Fi 6 APs and will provide similar 6Ghz coverage as today’s 5Ghz radios.
- Very Low Power (VLP) AP: VLP provides mobile indoor or outdoor usage from mobile clients for use cases like small cell coverage, hotspots, etc.
Use of these three device classes varies by geography and regulatory permissions.
What is the status of 6 GHz-enabled client devices (Wi-Fi 6E devices)?
Before devices can leverage the 6 GHz spectrum, the chipsets supporting this band must be available. Available chipsets come from several different companies. In addition, some high-end, gaming phones are hitting the market with Wi-Fi 6E support. Wi-Fi Alliance launched their certification program for Wi-Fi 6E and maintains a list of 6E enabled products. This means that Wi-Fi 6E is now ready for mass market adoption.
How do I choose a Wi-Fi 6E vendor?
Choose a vendor that demonstrates
- A track record of proven innovation
- Commitment to certification by industry standards (Wi-Fi Alliance)
- A full portfolio to support indoor, outdoor, hazardous location (HazLoc), and remote workers
What is the Wi-Fi 6E regulatory status?
Globally, the United States, South Korea, Saudi Arabia, Brazil, Chile, and Guatemala have each opened up 1200 MHz. In November 2020, the European Conference of Postal and Telecommunications Administrations (CEPT) published its decision to open an initial 480 MHz of spectrum for Low Power Indoor (LPI) devices and Very Low Power (VLP) devices that may operate both indoors and outdoors.
What are the differences in Wi-Fi 6E in the US and EMEA?
There is an agreement for Europe to allocate the band 5945 – 6425 MHz for Wi-Fi. Even though this is not the complete 6 GHz band, it still provides a lot of additional spectrum to use. However, to harmonize regulations globally and benefit from economies of scale and to accommodate future capacity needs, the Wi-Fi industry is working with regulators in Europe to open up the 6425 – 7125 MHz band as well.
Within Europe, the UK and Denmark deviate slightly from the European agreement. The UK will allow slightly higher transmit power and have a little more spectrum to use (5925 – 6425 MHz).
Wi-Fi 6 versus Wi-Fi 6E
|Wi-Fi 6||Wi-Fi 6E (6 GHz)|
2.4 and 5.0 GHz spectrum
2.4, 5 and now 6 GHz spectrum (Devices must be 6 GHz enabled.)
Includes all features in Wi-Fi 6 plus
Increased efficiencies to provide greater throughput with the same number of APs, ideal for dense environments and large numbers of IoT devices
Supports greater capacity and wider channels to support multigigabit traffic, ideal for high-definition video and AR/VR (Augmented Reality/Virtual Reality)
