iPhone 12 series hotspot function supports 5GHz WiFi
Apple has supported hotspot sharing in the iPhone 12 series using 5GHz WiFi to improve the loading speed of shared networks. 5GHz WiFi uses a higher frequency and has a faster network speed but poor penetration, while 2.4GHz WiFi is not as fast but covers a wider range.
Considering that most users are with their devices when using hotspot sharing, and the iPhone 12 series already supports 5G networks, hotspot speed is of course also very important.
Therefore, the hotspot sharing in iPhone 12 and iPhone 12 Pro enables 5GHz WiFi by default to speed up the sharing network speed and improve the actual user experience.
Although Apple has enabled 5GHz WiFi by default, it also supports users to manually switch hotspot sharing to 2.4GHz WiFi to share the network.
The reason is that some older devices do not support 5GHz WiFi, so they can only use 2.4GHz WiFi. Apple provides two frequency support based on compatibility considerations.
When the user goes to the personal hotspot menu, he will see the option of maximum compatibility, and when the user turns on the option of maximum compatibility, it will switch to 2.4GHz WiFi.
At present, this function seems to only support the iPhone 12 series. Old models such as the iPhone 11 series do not know whether Apple will bring support through software updates.
