Indoor navigation refers to the technology and methods used to help people find their way inside buildings or complex structures. Unlike outdoor navigation, which often relies on GPS, indoor navigation uses various systems such as Wi-Fi, Bluetooth, and beacons to determine a person's location and guide them to their destination. This technology is particularly useful in large venues like shopping malls, airports, and hospitals, where traditional maps may not be effective. Indoor navigation apps can provide step-by-step directions, helping users easily locate stores, gates, or departments within these spaces.
