A hotspot (Wi-Fi) is a physical location where people can access the internet wirelessly using a device like a smartphone, tablet, or laptop. These hotspots are typically created using a router that connects to the internet and broadcasts a signal over a limited area, allowing multiple users to connect simultaneously. Hotspots can be found in various places, such as cafes, airports, and libraries. They may be free or require a fee for access. Some mobile devices can also act as personal hotspots, sharing their cellular data connection with other devices, which is useful when traditional Wi-Fi is unavailable.
