What is wi-fi 6 ? How is it diffrent from current wi-fi ?


Wi-Fi 6 is the next-generation, faster-speed 802.11ac wireless standard. Not only speed, but Wi-Fi 6 will also provide better performance in congested areas, from stadiums to every household. And it will be released in 2019.

Wi-Fi has many versions, “number of cheeks” really.

Yes, Wi-Fi now has many versions and has different version numbers! Even obscure old Wi-Fi standard names like 802.11ac have been changed to a more memorable name for users, Wi-Fi 5.

And here are the Wi-Fi versions:

Wi-Fi 4 is 802.11n, released in the year 2009.

Wi-Fi 5 is 802.11ac, released in the year 2014.

Wi-Fi 6 it is the new version, also known as 802.11ax, expected to be released in 2019.

The Wi-Fi Alliance announces that these Wi-Fi version numbers appear in the software so you can know which Wi-Fi networks are newer and faster when connected on smartphones, tablets or laptop. Therefore, you will probably soon see Wi-Fi version numbers on your phone, tablet or laptop.


Older Wi-Fi versions are not widely used and therefore are not officially “numbered.” But if so, they will have the following order:

Wi-Fi 1 will be 802.11b, released in 1999.

Wi-Fi 2 will be 802.11a, also released in 1999.

Wi-Fi 3 will be 802.11g, released in 2003.

Wi-Fi faster

As usual, the latest Wi-Fi standard provides faster data transfer speeds. If you use a Wi-Fi router with a single device, the maximum potential rate of Wi-Fi 6 will be up to 40% higher than Wi-Fi 5.

Wi-Fi 6 has excellent speed thanks to more efficient data encryption, resulting in higher throughput. Lots of data is packed into the same radio waves. These signal-decoding and decoding chips continue to be more powerful and can handle more data.

This new standard even speeds up on 2.4GHz networks. While many places have switched to Wi-Fi 5GHz for less noise, the 2.4GHz system is still better at penetrating solid objects.

Longer battery life

The “target wake time” feature (TWT) means your smartphone, laptop, and other Wi-Fi-enabled devices will also have longer battery life.

Specifically, when your device is connected to Wi-Fi, it can tell you exactly when you should set up Wi-Fi to “sleep” and when to “wake up” Wi-Fi to receive Next line. This will save energy because that means Wi-Fi radios can spend more time in sleep mode. And that means longer battery life.

This will also help the Internet of Things devices consume less power when connected via Wi-Fi.

Better performance in crowded areas

Wi-Fi tends to be slow when you are in a crowded place, and many devices are connected. In places like stadiums, airports, hotels, shopping centers or even a crowded office, Wi-Fi can be slow.

New Wi-Fi 6, also known 802.11ax, incorporates many technologies to support this. Intel said Wi-Fi 6 would improve the average speed of each user at least four times in areas with multiple connected devices.

Search for “Wi-Fi 6” and “Wi-Fi 6 Certified”

When buying a new device, you won’t need to look for eyeglasses in the specs table and try to remember whether 802.11ac or 802.11ax is the latest standard. The device manufacturer will only offer Wi-Fi 6 or Wi-Fi 5.

You’ll also start to see the “Wi-Fi 6 Certified Certified” logo on devices that have passed the Wi-Fi Alliance certification process. Previously, a “Wi-Fi Certified” logo, but it didn’t tell you which Wi-Fi generation it was unless you looked at the specs.

Wi-Fi 6 routers are also expected to support WPA3 for a more secure connection with Wi-Fi networks, but WPA3 support is not a requirement.

When will you be using Wi-Fi 6?

Some routers may have advertised “802.11ax technology”, but Wi-Fi 6 is not yet complete. Also, no device is ready to connect to Wi-Fi 6.

The Wi-Fi Alliance hopes the new Wi-Fi standard will be finalized and the hardware will be released in 2019. You don’t need to think about it – in the future, new routers, phones Smart, tablet, laptop, and Wi-Fi-connected devices will only come with this technology.

As always, both send and receive devices need to support the latest Wi-Fi generation so that you can enjoy the advantages. In other words, if any of you want Wi-Fi 6 performance on your phone, you will need both a wireless router and a smartphone that supports Wi-Fi 6. If you connect the device The laptop only supports Wi-Fi 5 with your Wi-Fi 6 router, that specific connection will work in Wi-Fi 5 mode. But your router can still use Wi-Fi. Fi 6 with your phone at the same time.

Wi-Fi version numbers are high but not required.

The Wi-Fi version numbers are high, as it helps ordinary people to remember and understand Wi-Fi generations easily. It is a simple, easy change and should have been there for a long time. Many people can get easily faster Wi-Fi speeds by upgrading own home routers, but not everyone knows that.

However, the Wi-Fi Alliance has no right to force companies to use these version numbers, although they encourage their companies to adopt them. Some manufacturers may ignore version numbers and instead only call the new generation Wi-Fi “802.11a”. Many companies are also likely to refuse to rename the existing 802.11ac Wi-Fi to Wi-Fi 5.

Hope all companies will quickly apply the name of the new generation of Wi-Fi so that users can distinguish.
