In Wi-Fi technology, a "hotspot" refers to a physical location that provides wireless internet access to users through a Wi-Fi network. Hotspots can be found in public places like cafes, airports, and libraries, allowing individuals with Wi-Fi-enabled devices to connect to the internet. Typically, hotspots use a router to transmit signals within a certain range, enabling several users to connect simultaneously. They often require authentication or a password for access, especially in private or commercial settings.
