Analysis of Indoor Localization Techniques

Location-based applications and services have gained growing business interest in recent years. Systems for indoor localization relay on various localization techniques, which can vary significantly when it comes to the technology, accuracy, cost, robustness, etc. Unlikely outdoor localization, the indoor localization requires a higher precision and can be more challenging due to the signal dispersion and obstacle reflections. Currently, there are numerous solutions proposed in this field of research. In this paper, we provide the survey of the existing technologies and techniques for indoor localization systems.
