The 6 GHz spectrum allows for any combination of additional channels, including 59 additional 20 MHz channels, 29 additional 40 MHz channels, 14 additional 80 MHz channels, and 7 additional 160 MHz channels. This is in contrast to the 2.4 GHz ISM band, which has only 80 MHz of unrestricted spectrum.

The 6 GHz band is in use by many licensed services, including fixed point-to-point radios, fixed satellite service, broadcast auxiliary service, and cable television relay services. In the US, there are 47,695 unique uses between 5.925 and 7.125 GHz.

The 6 GHz WiFi connections should deliver faster speeds with reduced latency, as well as experiencing less interference from other signals. This is because the 6 GHz band offers more channels and wider bandwidths than the traditional 2.4 GHz and 5 GHz bands.

Here's a comparison of the spectrum available in different bands:

The 6 GHz WiFi band is a game-changer for wireless networking, offering faster speeds, reduced latency, and less interference.

The 6 GHz frequency band offers a whole new landscape of channel availability, with 7 "superwide" channels available at 160 MHz-wide.

In the US, the 6 GHz band provides up to 1200 MHz of additional bandwidth, allowing for a total of 59 20 MHz-wide channels.

At normal power mode, Access Points (APs) are limited to 850 MHz of spectrum space, but on low power mode, APs can use the entire 1200 MHz spectrum range.

This means that in a space with more access points at lower power, devices on 6 GHz can operate over 59 20 MHz-wide channels.

Here's a breakdown of the channel availability on the 6 GHz band:

With more channels available, the 6 GHz frequency band can effectively quadruple the amount of space available to your WiFi connection, reducing congestion in dense environments.

The 6 GHz band is a shared frequency band, and to avoid interference with primary users, the FCC defines different classes of Wi-Fi Access Points with their own transmit power rules.

The FCC defines three types of device classifications: Standard Power (SP), Low Power Indoor (LPI), and Very Low Power (VLP).

These power classifications are important because they determine how access points can operate without causing undue interference.

To avoid interference, devices in the 6 GHz band use a system called Automated Frequency Coordination (AFC), which connects to a cloud-based database to report their position and determine the risks of interference.

Here are the different classes of Wi-Fi Access Points and their characteristics:

There are two types of device classifications defined by the FCC, which have their own transmit power rules to avoid undue interference with existing 6GHz users.

The Standard Power (SP) devices have a significant risk of interfering with fixed satellite services used by broadcasters and cable providers.

Low Power Indoor (LPI) devices operate at reduced power levels, making them less likely to cause interference.

Very Low Power (VLP) devices operate at very low power levels and are very unlikely to cause any interference.

These power classifications are crucial in determining how access points with different power levels can operate.

The 6 GHz band has 1200 MHz of spectrum and 59 new 20 MHz channels, which can make scanning the whole band a time-consuming process.

A device would require almost 6 seconds to complete a passive scan of the entire band with a dwell time of 100 ms per channel.

The new fast passive scanning process focuses on a reduced set of channels called Preferred Scanning Channels (PSCs), which are a set of 15 20-MHz channels spaced every 80 MHz.

Avoiding interference with primary users is crucial when operating in the 6 GHz band. The FCC defines two types of device classifications to ensure this.

In the 6 GHz band, Wi-Fi is considered a low-powered user, which means its signals won't travel far and cause interference with primary users. By sharing radio spectrum in this way, it opens up more valuable space for low-power users, increasing spectrum usage efficiency.

The FCC has classified Wi-Fi Access Points into three categories: Standard Power, Low Power Indoor, and Very Low Power. Each category has its own transmit power rules to minimize interference.

Standard Power devices have a significant risk of interfering with existing 6 GHz users, including fixed satellite services used by broadcasters and cable providers. Low Power Indoor devices, on the other hand, operate at reduced power levels, making them less likely to cause interference.

Here's a breakdown of the three device classifications:

Automated Frequency Coordination (AFC) is also a crucial tool in avoiding interference. AFC is a system that allows devices to check a database to confirm their operation won't impact registered users.

Currently, Wi-Fi 6E routers are quite expensive, making them a hard sell for most people at this time.

Wi-Fi 6E devices will probably start appearing in 2021 and become more common heading into 2022.

It's worth waiting for Wi-Fi 6E if you're looking to chase high channel widths and high data rates, as it offers plenty of benefits in this area.

There's no official timeline for when regulators around the world will make the spectrum available for unlicensed use, which means Wi-Fi 6E has no definitive release date in most countries.

You might not need to hold out for Wi-Fi 6E, especially for a home network, as upgrading to Wi-Fi 6 now might make more sense.

Suggestion: What Is the Difference between Wifi 6 and 6e

Wi-Fi 6E devices will require all new devices to get the benefits, and we don't have any of those yet, which means waiting for mature Wi-Fi 6E products or Wi-Fi 7, due in 2023 or 2024, might be a better option.

It will take time until the benefits of Wi-Fi 6E are relevant to most people, so patience is key when it comes to upgrading your network.

A different take: How to Check If Wifi Is 6 or 6e

Switching to Wi-Fi 6E is still a pricey proposition, with most upgraded routers costing a pretty penny.

Currently, Wi-Fi 6E is still in its infancy, so it's hard to say when prices will come down.

The benefits of Wi-Fi 6E, such as potentially faster Wi-Fi speeds, better overall connectivity, and less interference, are undeniable.

However, for most people, these benefits may not be worth the high cost of an upgraded router.

It's worth considering whether the advantages of Wi-Fi 6E are worth the investment, especially if you're not experiencing significant issues with your current Wi-Fi setup.
