Indoor Positioning of Workers and Monitoring Climatology in Mines Using FM with RSSI

Abstract

Location based services are becoming a most useful technology in our day-to-day life. Wide utilization of Global Positioning System (GPS) in devices like mobile phones combined with Wi-Fi and cellular networks have solved the problem of outdoor positioning or localization and emerged as a market trend. This, however, is the case only for outdoors. There are many areas, which require the knowledge of user position in indoors. Awareness of user’s location is important in such areas as smart environments, assisted daily living, behaviour analysis studies. The main objective of this thesis was A Dedicated RF Frequency Carrier with Modulated Signal is used for mapping the Movement of Object or Human being. The performance of indoor localization using FM transmitter and receivers are compared with Wi-Fi based indoor positioning which has significantly lower Frequency range when compared to FM.
