Indoor Localization Technology

Indoor localization determines the location of an object or a person within an indoor environment. Unlike outdoor environments, indoor spaces pose unique challenges for localization due to the absence of GPS signals and limited line-of-sight conditions.

An indoor localization technique is a specific method or approach used to determine the location of an object or a person within an indoor environment. These techniques leverage various technologies and algorithms to estimate position accurately. Some commonly used indoor localization techniques include fingerprinting, trilateration, angle of arrival, time of flight, sensor fusion and machine learning.

Indoor localization plays a crucial role in various domains and offers several important benefits including improved navigation, emergency response, asset tracking and inventory management, location-based services, indoor analytics and optimization, augmented reality and virtual reality and Internet of Things (IoT) and smart environments.

Several indoor localization techniques are used to determine the position of objects or people within indoor environments. Some commonly employed techniques include Wi-Fi, Bluetooth, infrared and ultrasound, magnetic field, visible light communication, sensor fusion, computer vision and radio frequency identification.

Indoor localization enhances navigation, safety, efficiency, personalization and interaction within indoor environments. It benefits individuals, businesses and organizations across various sectors, improving user experiences, optimizing operations and unlocking new possibilities for innovation.

A localization map is a visual representation of an indoor space that displays the positions of tracked objects or individuals, aiding in navigation and spatial analysis.​

Accuracy varies depending on the technology used. For instance, UWB can achieve centimetre-level accuracy, while Wi-Fi and BLE typically offer meter-level precision.

Considerations include the specific needs of the environment, desired accuracy, scalability, integration capabilities and support services offered by the indoor positioning system company.
