Abstract
Various implementations disclosed herein include a method of providing indoor navigation services. The method may include transmitting, via light-based communication (LCom) signals by each of a first plurality of luminaires, identifiers assigned to each of the plurality of luminaires, and transmitting, via LCom signals by a second plurality of luminaires, mapping information associating the identifiers of each of the first plurality of luminaires with a location of each of the first plurality of luminaires. The first plurality of luminaires may transmit the LCom signals towards the ground of an indoor environment while the second plurality of luminaires may transmit the LCom signals towards the ceiling of the indoor environment and are reflected downwards.
