What is 802.11ax Wi-Fi? Learn about 6th generation Wi-Fi

With the higher demand for this internet nowadays, the connection speed must be faster and more stable. Therefore, Wi-Fi 6 was born to meet the increasing needs of people using the internet. Let's learn about Wi-Fi 6 with WebTech360!

 

1. What is 802.11ax Wi-Fi?

802.11ax is the 6th version of the 802.11 standard, so it is called Wi-Fi 6 , used to transmit wireless networks or commonly known as Wi-Fi.

Wi-Fi 6 is not a new tool for connecting to the internet - instead, it's an upgraded standard that compatible devices, especially routers, can leverage for transmission. more efficient Wi-Fi performance.

6th generation Wi-Fi will meet the needs of the growing information technology industry today and in the future.

Wi-Fi Alliance (WiFi Alliance) officially launched Wi-Fi 6 on September 16 with high speed, wide coverage and higher security than the previous generation.

2. Why update Wi-Fi 6 standards?

Wi-Fi 6 offers lower latency compared to previous Wi-Fi generations, Wi-Fi 6 delivers the ability to process data between devices as quickly as possible.

Wi-Fi 6 also provides data transfer rates of more than 10,000 Mbps, higher than Wi-Fi 5, which is only 7,000 Mbps.

To identify which Wi-Fi standard is working on routers, phones , laptops , tablets or other devices, you can find the Wi-Fi 6 logo printed on the product box or stick directly onto the product. products (for laptops), ...

However, the Wi-Fi Alliance (WiFi Alliance) has also proposed plans to display the Wi-Fi generation. These icons look similar to a regular Wi-Fi signal with the number circled out in the signal.

3. Advantages of Wi-Fi 6

The first is the lower latency compared to previous generation Wi-Fi standards. Meaning there is no waiting time for data to be sent, and it improves the download speed , helping to avoid lost connections and other problems.

Because Wi-Fi 6 uses more advanced technologies such as OFDMA (orthogonal frequency division multiple access). Basically, it helps to encapsulate data into better signals .

Of course, Wi-Fi 6 is also faster, with full support for technologies like MIMO * , the quality of the connection will be dramatically improved for Wi- compatible mobile and laptop devices Fi 6, while also speeding up content delivery.

(*) What is MIMO?

MIMO (Multiple In, Multiple Out) is a way of using multiple antennas to transmit and receive signals of a wireless connection. Thanks to that, electronic devices such as smartphones, tablets, and laptops can receive wifi more easily and exploit the full capacity of the Wifi Router. In other words, MIMO is a part of wireless communication technology, depending on the number of antennas and transceivers, so the connection speed is corresponding.

Even if you don't increase your internet speed, these improvements will increase your Wi-Fi speed.

From 2020, there will be more and more laptop devices supported with Wi-Fi 6, improving the speed of internet access, thereby improving daily work efficiency.

​

Wi-Fi 6 has less signal resistance thanks to improved beam direction, allowing beams to pass through walls with less signal breakage compared to older Wi-Fi standards. .

Beam orientation is the trick your router uses to focus the signal on a particular device, especially if that device has problems with connectivity.

​

The new "target wake time" (TWT) feature helps smartphones, laptops and other Wi-Fi enabled devices to have longer battery life.

Specifically, Wi-Fi 6 technology will automatically recognize when your device is active to activate Wi-Fi and when your device is not in use (not using range 30 minutes) to automatically disconnect Wi-Fi. This will help save more energy as your device will spend more time in "sleep" mode and that means longer battery life.

4. Do I need a new router to use Wi-Fi 6?

There are very few devices on the market that support 6th generation Wi-Fi connection. But they are really necessary at this time. It is expected that by the end of 2019 it will officially launch on the market with the 802.11ax Wi-Fi standard. Accompanying WPA3 is a new wireless security protocol that will also come along with this standard.

So you need to check if your outer r can get a more secure WPA3 firmware update. If not, then you have to buy yourself a new device to help improve your Wi-Fi.

5. Wi-Fi enabled devices 6

This 6th generation Wi-Fi standard is well known since the launch of the Samsung Galaxy S10 , Galaxy S10 + super duo . In the near future, Wi-Fi generation 6 will be more popular and available on lower-segment smartphones.

Since the beginning of 2020, there are also many laptops supported with Wi-Fi 6 such as Acer Nitro 5 Laptop AN515 55 58A7 , Acer Aspire A514 53G
