发明名称 Real time location system and method for caching location information based on finger printing
摘要 Disclosed is a location tracking system and the method thereof for storing location information. The location tracking system includes at least one beacon apparatus arranged to transmit a beacon signal to a tag; a tag at any position respectively measuring a signal intensity of beacon signals received from surrounding at least one beacon apparatus, and transmitting a measured per-beacon signal intensity to a specific beacon apparatus; and a server arranged to determine if at least any one of signal intensities exceeds a set maximum value by analyzing a per-beacon signal intensity input from the specific beacon apparatus, and store a location-based signal intensity into a database by equally dividing a distance between corresponding beacon apparatuses and then distributing a measured signal intensity into a divided each position in multiple cases the signal intensity exceeds a set maximum value.
