What devices are used in wlan hotspots in shopping malls and hotels? Not a wireless router, right? Wireless switch?

Wireless AP is a wireless switch.

If you are a WLAN operator, specifically, you need an AP and an AC. In terms of transmission, if the power supply is PoE, a layer 2 or layer 3 switch supporting PoE is needed. If the transmission is PON, the remote end needs an ONU and an OLT.
