What does WiFi 6 mean? What are the improvements of WiFi 6
Now WiFi is everywhere in our life. In recent years, with the rapid development of wireless technology, WiFi has come out of the sixth generation. Do you know what WiFi 6 is? What are the advantages? Let's have a look.
What does WiFi 6 mean?
WiFi 6 is a naming rule proposed by the WiFi alliance of the wireless network standard. It changed 802.11ax to WiFi 6 and was released in 2019. Now the routers on the market are 802.11ac, that is, WiFi 5, which was released by the WiFi alliance in 2014, and the earlier 802.11n was released in 2009, which is the fourth generation of WiFi. WiFi 6 was renamed so that those who buy routers can clearly choose the standard without being fooled by unscrupulous manufacturers. The old naming of 802.11ac is too professional, so the WiFi Alliance came up with the WiFi 6 standard.
What are the advantages of WiFi 6
Speed:
The latest Wi Fi 6 standard provides faster data transmission speed. If you are using a single device Wi Fi router, the maximum potential speed of Wi Fi 6 should be about 40% faster than Wi Fi 5.
Wi Fi 6 improves the throughput through more effective data coding. The main thing is that more data is packaged into the same radio waves, and the chips that encode and decode these signals are more powerful, which can also handle additional work.
The new Wi Fi 6 standard has even increased the network speed of 2.4GHz. Although the industry has turned to 5GHz Wi Fi to reduce interference, 2.4GHz is still a magic weapon for penetrating solid objects. Moreover, due to the retirement of old equipment such as old cordless phones and wireless baby monitors, the interference to 2.4GHz should not be too large.
On standby:
WiFi 6 has TWT wake-up technology, which enables mobile phones / Notebooks and other clients to significantly shorten the time of holding and multi signal, so as to reduce battery consumption and prolong battery life.
When an access point communicates with a device (such as a smartphone), it can accurately "tell the device" when to put its Wi Fi wireless into sleep and when to wake it up to receive the next transmission. This working mode can save the power of Wi Fi client to a certain extent, which also means a longer standby time when the device uses battery.
Security:
WiFi 6 supports a new generation of WPA3 security protocol, which makes hackers have no way to start, enhances users' WiFi security, and protects users' privacy and bank property security.
