Have you heard the big news that WiFi 6E devices have been recently begun certifying by the WiFi Alliance? Yep, it’s true. For sure, this event is really significant since it does pave the way for all sorts of new devices taking advantage of the super-wide 6 GHz airwaves.
WiFi 6E is better than WiFi 6
It’s expected that there will be rapid adoption of millions of devices equipped with the latest WiFi standard this year. Are you ready to experience the superior speeds and super-wide bandwidth of WiFi 6E?
But while waiting for the official launch of WiFi 6E devices, why don’t you spend some minutes learning basic things about WiFi 6E and understand why and how it’s better than the older WiFi standards? Let’s do it right now! Here we go!
What is WiFi 6E?
Before jumping into exploring what next-gen WiFi 6E really is, let’s check out its previous WiFi standards, starting with the very first version of WiFi, 802.11b which dates back to 1999.
WiFi 1: 802.11b (released in 1999)
WiFi 2: 802.11a (released in 1999)
WiFi 3: 802.11g (released in 2003)
WiFi 4: 802.11n (released in 2009)
WiFi 5: 802.11ac (released in 2014)
WiFi 6: 802.11ax (released in 2019)
And just like WiFi 6, WiFi 6E is also called 802.11ax, but it operates on a different spectrum. More details on the differences between WiFi 6E and WiFi will be discussed more specifically in the next part of this writing.
Now, back to what WiFi 6E is, generally speaking, it’s the latest standard for an extension of WiFi 6, enabling the operation in the 6GHz band along with the currently supported 5GHz and 2.4GHz bands. In other words, WiFi 6E is WiFi 6 over the 6 GHz spectrum.
That means all the devices communicating on the 6GHz band would also be WiFi 6E devices. Of course, WiFi 6E is better than the previous versions in terms of range, speed, latency, and bandwidth since it is the latest WiFi standard right now.

How is WiFi 6E different from WiFi 6?
As you can see, WiFi 6E is identical to WiFi 6 with the letter “E” added, which stands for “Extended,” indicating the extended usable wireless band of 6 GHz. That’s why it’s said that WiFi 6E is the extension of WiFi 6. Due to that, there aren’t a lot of differences between these 2 WiFi standards.
The biggest difference between WiFi 6E and WiFi 6 lies in the spectrum they operate. WiFi 6E network operates on the 6GHz band, offering much higher bandwidth as compared to any older WiFi generations, including WiFi 6.
About 6GHz, it is the new frequency band having the range from 5.925GHz to 7.125GHz that allows up to 1200MHz of additional spectrum. Not like existing bands that WiFi users have been familiar with for years like the 2.4 and 5 GHz, the 6GHz band exists without interference or overlap.
Benefits of the next-gen WiFi 6E
What makes WiFi 6E (WiFi 6 over 6GHz band) better than WiFi 6 and older versions?
Access to the 6GHz frequency means a lot more bandwidth, lower latency, and of course, faster internet speeds, opening up resources for future innovations such as augmented reality (AR), virtual reality (VR), 8K streaming, and more.
To be more specific, WiFi 6E allows for seven additional 160MHz channels, enabling many more simultaneous transmissions at the maximum possible speeds. In that way, users will be able to enjoy AR/VR gaming, 8K movies, and large file downloads without buffering.
Do you want to get a clearer idea of the potential benefits of the 6GHz band that the new WiFi standard of 6E operates on? If that’s the case, let’s take a quick look at a simple comparison between 80MHz channel width availability to the 5GHz band of frequency. Well, the 5GHz band currently provides 6 non-overlapping 80MHz channels. But with the 6GHz band, there’s a 133% increase of channels to up to 14 non-overlapping 80MHz channels.
WiFi 6E offers up to 7 non-overlapping 160MHz-wide channels
WiFi 6 now also provides 160MHz-channel widths in order to accommodate data-hungry applications and programs. But that still can’t compare to WiFi 6E or WiFi 6 over 6GHz spectrum which allows a higher number of non-overlapping 160MHz channels (7 channels). That will help eliminate significant congestion, especially in areas where so many networks are operating like MDUs, Enterprises, and more.
In a nutshell, WiFi working on the 6GHz band is expected to double the effective throughputs as it has multiple 160 MHz channels, compared to the practical 80 MHz channels in the 5GHz band.
WiFi 6 over 6GHz band will help change the game for WiFi 6
WiFi 6E: Unlock WiFi 6’s full potential
WiFi 6E or WiFi 6 over 6GHz band will help change the game for WiFi 6. Though WiFi 6 offers upgraded performance in network capacity and efficiency, its advantages aren’t fully realized while competing with other transmissions. But the availability of the 6GHz band only for WiFi 6 traffic (WiFi 6E) will allow it to meet its intended potential.
Here are basic things to know about WiFi 6E and its promising advantages. Though it’s the extension of WiFi 6, WiFi 6E or WiFi 6 over 6GHz band of frequency will help level up our WiFi experiences in a very significant way. It’s no coincidence that next-gen WiFi 6E is considered the biggest upgrade to WiFi in 20 years. That’s all for today’s article. Next time, we will have an article comparing 6HGz WiFi, 5GHz WiFi vs Ethernet.
