Indoor positioning refers to the technology that determines a person's location within a building or enclosed space. Unlike GPS, which works well outdoors, indoor positioning uses various methods such as Wi-Fi, Bluetooth, or ultrasonic signals to pinpoint locations. This technology is useful in places like shopping malls, airports, and hospitals, helping users navigate complex environments. The systems often rely on a network of beacons or sensors that communicate with mobile devices. By analyzing the signals received from these devices, the system can calculate the user's position with reasonable accuracy. Indoor positioning enhances user experience by providing directions, location-based services, and real-time information.
