Solution 1:

It makes the device act as a wireless router (i.e. switches Wi-Fi to "access point" mode and serves DHCP) so that other devices could connect to it.

This is exactly the same thing as the "Hotspot" feature in Android or iOS.

The purpose is to allow you to temporarily share another type of Internet connection (e.g. LTE or Ethernet) over Wi-Fi, without having a separate wireless router.
