What does the number 6 on wifi mean? Understand it in seconds: A comprehensive and detailed explanation of WiFi4, WiFi5 and WiFi6

php editor Xiaoxin reveals the meaning of WiFi’s digital codes for you: WiFi4, WiFi5 and WiFi6. These numbers represent different wireless network standards, each with different speeds and features. Understanding these standards can help us better select and use wireless devices to obtain faster and more stable network connections. Next, let us learn more about the specific characteristics and differences of WiFi4, WiFi5 and WiFi6.

Starting from Apple iPhone 11, it has fully supported the new WiFi6 wireless network. Nowadays, many mid-range or high-end motherboards support WiFi6 wireless network cards, but many people still don’t understand what WiFi6 is. What does it mean? I was asked this question when I came to install it, so today Xiaolong, the installation home, will introduce WiFi6 to the fans in an easy-to-understand way.

What are the differences between WiFi4, WiFi5 and WiFi6 Popular science

What does WiFi6 mean?

WiFi6 is the naming rule proposed by the WiFi Alliance. On October 4, 2018, the 802.11AX protocol was renamed WiFi 6 to facilitate consumers to better identify it. The main reason is that the protocol names of 802.11AX and the previous generation 802.11AC are too similar. Only the ending letters are different, and consumers have no idea which generation is WiFi 6.

Since 802.11AX was renamed to WiFi6, the previous generations of protocols also changed their names. Most routers on the market currently use the 802.11AC protocol and were also renamed WiFi5. The earlier 802.11N protocol, Renamed WiFi4.

WiFi4, WiFi5, and WiFi6 are different wireless network standards. This is a bit like the mobile network upgrading 2G, 3G, 4G, and 5G. The same is true for WiFi. It will be updated with the progress of the times, providing more Fast transmission rate, reduce network delay, make the network smoother.

Regarding the differences between WiFi4, WiFi5, and WiFi6, we can look at the following parameter comparison.

WiFi4, WiFi5, WiFi6 parameter comparison

Main advantages of WiFi6:

1, WiFi6 Faster speed

The maximum rate of WiFi6 can reach 9.6Gbps, which means the theoretical transmission speed reaches 1.2GB/s. The maximum rate of WiFi5 is 3.5Gbps. Compared with the two, the theoretical transmission rate is increased by nearly 3 times, while the maximum rate of WiFi4 is only 600Mbps.

2. WiFi6 supports both 2.4G and 5G frequency bands

WiFi5 only supports the 5G frequency band, while WiFi6 supports both 2.4G and 5G frequency bands, fully covering low-speed and high-speed devices.

3. WiFi 6 supports simultaneous parallel transmission by multiple terminals

WiFi 6 adopts OFDMA technology to support simultaneous parallel transmission by multiple terminals, effectively improving efficiency, reducing latency, and reducing network freezes.

Regarding what is meant by multiple terminals transmitting in parallel at the same time, here is another example. Suppose there are three users who have opened web pages, videos, and chat tools respectively. When WiFi5 processes these data, it needs to be processed three times. Transmit data, while WiFi6 only needs to transmit data once, effectively reducing network latency.

##4. WiFi6 is more secure:

WiFi6 supports WPA3 encryption protocol. When a device is connected to a wireless router to access the Internet, it requires a certified WPA3 encryption protocol, which is more secure and better prevents network attacks, password brute force cracking, etc.

5. WiFi6 is more power-saving and consumes less power

WiFi6 supports TWT technology, allowing terminal devices to enter a sleep state when not transmitting data, making the device more power-saving and consuming less power. Low.

For example, take a WiFi5 router. It is turned on 24 hours a day regardless of whether a device is connected. However, WiFi6 can wake up on demand and will only work when a device is connected. If it is not connected When the device is powered on, it will be in a hibernation state, allowing mobile phones, notebooks and other devices to save power when using the battery to obtain longer standby time.

About Wifi6 conditions:

However, it should be noted that if your mobile phone, laptop, desktop and other devices support WiFi6, then your router also needs to support WiFi6 to support it. Of course, the router supports it. WiFi6, it will not work if the device does not support WiFi6.

Summarize:

The main advantages of WiFi6 are higher bandwidth, high concurrency, low latency and low power consumption. I believe that many families have not yet set up WiFi6 networks. WiFi6 must be the future trend. WiFi6 is very suitable for people who have high requirements for wireless networks. If your home’s bandwidth reaches Gigabit, then WiFi6 is more suitable for you, or you can play mobile e-sports. For gamers, you can also consider WiFi6 to reduce network latency. Or, if you have a lot of people online at home and want to improve your wireless network, you can also consider setting up a WiFi6 wireless network, which supports MU-MIMO technology and can process data from 8 devices at the same time. transmission.
