Interest in indoor optical positioning systems has increased over the past decade, as they
achieve an accuracy in the range of centimeters in three dimensions (3D) using light …

A system for indoor localization using partially collimated light from individual LEDs inside a
luminary is proposed, simulated and tested experimentally. A simple biconvex lens provides …

A novel sensor architecture, called Planar Circular Photodiode Array (PCPA) is proposed to
provide azimuth measurements for indoor localization systems. The transmitters are blinking …

Indoor navigation is hardly managed by the usual Global Positioning System (GPS) due to
the strong attenuation of signals inside the buildings. Alternative based on RF optical …

In this paper, an indoor localization system using light emitting diodes (LEDs) is presented.
Location of an object is determined by scanning two LEDs at pre-defined angles which are …

Indoor positioning or localization based on visible light communications (VLC) is an
emerging technology with wide applications. In conventional localization schemes, the …

This paper presents an experimental evaluation on the accuracy of indoor localisation. The
research was carried out as part of a European Union project targeting the creation of ICT …

Indoor positioning systems (IPSs) based on visible light communication (VLC) shall be at the
forefront of indoor localization technology in the near future. However, the existing VLC …

Visible Light Communication (VLC) is currently a research topic due to the possibility to
handle the general, worldwide demanding need for communication. VLC uses Light Emitting …
