摘要：One of the popular methods studied for indoor positioning is based on Wi-Fi signal strength. Variation in signal strength that depends on communication distance is an important parameter. But signal strength shows not only intuitive results but also irregular results. Depending on the experiment, using only wireless signal strength to determine communication distance may have evident positioning errors. Therefore, some additional methods for increasing positioning accuracy are needed. Time of flight (ToF) and additional sensors to support positioning are needed.In this study, a method based on only Wi-Fi signal strength and other hybrid methods which are used additional upon wireless signal method are studied. Compass sensors and laser sensors were provento begood additional methods for better positioning in a Wi-Fi-based system.
