The accuracy of the received signal strength-based visible light positioning (VLP) system in
indoor applications is constrained by the tilt angles of transmitters (Txs) and receivers as
well as multipath reflections. In this paper, for the first time, we show that tilting the Tx can be
beneficial in VLP systems considering both line of sight (LoS) and non-line of sight
transmission paths. With the Txs oriented towards the center of the receiving plane (ie, the
pointing center F), the received power level is maximized due to the LoS components on F …

The continuous positioning of a mobile user equipment (MU) in a prompt way is a
fundamental requirement in several indoor applications related to ubiquitous computation,
assisted living environments, and security/surveillance systems. Motivated by this fact, the
current contribution reports a low-complexity visible light positioning (VLP) method suitable
for indoor environments in the Big Data era. The proposed architecture consists of multiple
light-emitting diodes (LEDs) as light sources and an MU equipped with a photodiode (PD) …
