Indoor Positioning System

A technology system that determines the location of people or objects inside buildings where GPS signals are unavailable or unreliable. Indoor positioning systems use various technologies including Wi-Fi fingerprinting, Bluetooth Low Energy (BLE) beacons, ultra-wideband (UWB), RFID tags, infrared, and computer vision. For accessibility, IPS is a critical enabling technology for indoor navigation and wayfinding applications that help people with disabilities navigate complex buildings such as hospitals, airports, and shopping centers. Without reliable indoor positioning, navigation tools cannot provide accurate turn-by-turn directions or adapt routes based on a user's accessibility needs.
