▶ What is WiFi 6?
When it comes to 6,For wifi1, 2, 3... peope may not be particularly clear. In 2018, the WiFi alliance decided to directly call the new generation of WiFi technology 802.11ax WiFi 6, so it replaced the previous one.
Make a simple list:
802.11b — WiFi 1 (1999)
802.11a — WiFi 2 (1999)
802.11g —WiFi 3 (2003)
802.11n — WiFi 4 (2009)
802.11ac —WiFi 5 (2014)
▶ Transmission speed of WiFi 6
Here we mainly talk about its theoretical speed:
According to the theoretical speed of WiFi 6 above, let's take a look at 5g; The 5g uplink peak transmission rate is 10Gbit / s and the downlink peak transmission rate is 20gbit / s. WiFi 6 has a peak rate of 600mbit / s for a single spatial stream with a bandwidth of 80MHz, and 9.6gbit/s for a bandwidth of 160MHz and 8 spatial streams. Generally speaking, the two can stand in the same echelon
▶ New technologies added to WiFi 6
-MU-MIMO (faster than before)
-OFDMA (access more devices at the same time)
-TWT (lower power consumption and more power saving)
