The study on the LBS for WiBro repeater

휴대인터넷 중계기를 위한 LBS 적용 방안에 관한 연구

WiBro service provider have made an effort to provide the subscriber's location and have deployed LBS system using cell-ID method. Cell-ID method has a location error problem if repeater is used on the other cell places at the same time. We introduce and analysis LMU(Location Measurement Unit) on the repeater fer location detection of subscriber which is serviced via the repeater. In this paper we propose the method using LMU on the repeater to avoid these location errors and to provide more exact location to the subscriber. we can conclude that the location error can be more exact at the building which uses repeater. It represents in which level the subscriber is serviced at the building.
