Wider range of services has become applicable to indoor space due to the spread of Information and Communication Technology and of smartphone. It is required to deploy of accurate indoor localization systems in order to provide improved indoor services utilizing location of user. In this paper, we discuss indoor localization technologies concerning Bluetooth 5.1 and Impulse-Radio Ultra-Wideband and techniques regarding Angle of Arrival, Angle of Departure, Time of Arrival and Time Differential of Arrival, respectively. We also compare each technology in terms of accuracy and range. |
