<human>:  What is the difference between a mobile hotspot and Wi-Fi?
<bot>: The main difference between a mobile hotspot and Wi-Fi is that mobile hotspot uses a cellular connection, while Wi-Fi requires a wireless internet connection. Mobile hotspots also provide more flexibility than Wi-Fi since they can be used anywhere with a cellular signal, while Wi-Fi is limited to the range of the router. Additionally, mobile hotspot connections are typically more secure than public Wi-Fi networks.
