Localization in 5G Ecosystem with Wi-Fi

Location awareness is essential in 5th generation (5G) ecosystem to enable location-based services and to efficiently manage the network. This paper presents a method for efficient localization based on the fusion of heterogeneous observations gathered with different technologies in the 5G ecosystem. In particular, a soft information (SI)-based approach is developed for hybrid localization fusing 5G and Wi-Fi measurements. Results obtained in an indoor environment compliant with 3rd Generation Partnership Project standards quantify the benefits of hybrid localization via SI with respect to the case of a single technology.
