Abstract
An indoor positioning system and an indoor positioning method allow all of the wireless base stations and mobile terminals in the same interior space to synchronously generate their time slots. Further, each mobile terminal transmits a positioning signal only at a preset time point in each time slot to prevent collisions between mobile terminals transmitting the positioning signals.
