Abstract
An apparatus and method for providing indoor location information are disclosed herein. The apparatus includes a signal reception unit, a global positioning system (GPS) data reception unit, a frame generation unit, a scheduling unit, and a signal transmission unit. The signal reception unit receives a lighting control frame from a lighting control device. The GPS data reception unit receives location data from GPS satellites. The frame generation unit generates a location data frame by extracting the location of an illumination light stored in a lighting arrangement storage unit, modifying the location data and adding a header to the modified location data. The scheduling unit schedules the lighting control frame or the location data frame. The signal transmission unit transfers the lighting control frame or the location data frame to the corresponding illumination light based on the results of the scheduling of the scheduling unit.
