IndoorLokalisierung

IndoorLokalisierung refers to the process of determining the precise location of an object or person within an indoor environment. Unlike outdoor localization systems that rely on global positioning systems (GPS), indoor environments present challenges such as signal obstruction by walls and buildings, and the absence of direct satellite visibility.

Various technologies are employed for indoor localization. Radio frequency-based methods are common, including Wi-Fi positioning, which uses the signal strength from multiple Wi-Fi access points to triangulate a device's position. Bluetooth Low Energy (BLE) beacons are another popular choice, emitting signals that can be detected by nearby devices, allowing for proximity-based or trilateration-based positioning. Ultra-wideband (UWB) technology offers high accuracy by using short radio pulses to measure time-of-flight, enabling precise distance measurements.

Other approaches include magnetic field-based localization, which utilizes variations in the Earth's magnetic field or artificially generated magnetic fields. Inertial measurement units (IMUs) found in smartphones can also contribute to localization through dead reckoning, estimating position based on previous location and motion data. Vision-based systems, using cameras to recognize visual landmarks or track movement, are also gaining traction.

The applications of indoor localization are diverse, spanning retail for customer tracking and personalized offers, logistics for inventory management and asset tracking, healthcare for patient and equipment location, and smart buildings for optimizing energy usage and security. Accuracy, cost, infrastructure requirements, and power consumption are key factors influencing the choice of an indoor localization technology.
