Abstract
Techniques for determining an actual position of a portable device are disclosed. In an embodiment, a two-tier triangulation and wireless beacon-enabled luminaire detection approach is implemented. An estimated position of a device is determined using wireless (e.g., wireless beacon) triangulation based on a signal parameter of a signal received from a wireless access point. The field of view of the portable device may be used to estimate positions of luminaires proximate the portable device. The actual position of the luminaires may be determined from the estimated position by querying a database. A second triangulation may be performed using the known position of the luminaires to determine the position of the portable device with respect to the actual position of the luminaire.
