An Indoor Positioning and Navigation System (IPNS) is a technology solution designed to determine the real-time location of people, devices, or assets inside buildings where GPS signals are weak or unavailable. Unlike outdoor navigation, indoor environments are complex due to walls, floors, furniture, and signal interference. Indoor positioning systems solve this challenge by using a combination of wireless communication technologies, sensors, and mapping tools to provide accurate indoor location tracking and navigation guidance.
Indoor positioning works by identifying a user’s location through signals received from installed infrastructure such as Wi-Fi access points, Bluetooth beacons, RFID tags, Ultra-Wideband sensors, or even visible light communication systems. These signals are analyzed using algorithms that calculate the user’s position based on distance estimation, signal strength, or time delay.
