Abstract
Design of a Real-Time Indoor Positioning System Based on Visible Light Communication
Highlights
The current outdoor positioning systems, such as Global Positioning System (GPS) and Global Navigation Satellite System (GLONASS) are widely available in many devices in the market since the 90’s, and it has brought the possibility to know our location and the location of any devices around the world [1]
In indoor environments, some positioning methods exist, but these technologies are not so popular and/or are limited by accuracy, complexity, cost, power consumption, range, robustness and scalability [3]–[6]. This is the reason why Visible Light Communication prospects a promising solution for indoor localization systems, where the same source of light might be used for illumination, communication and positioning through the modulation of commercially available light-emitting diodes (LEDs) [7]
This article is organized as follows: Section 2 does an overview of the design of the Indoor Positioning System (IPS); Section 3 describes the positioning algorithm deployed; Section 4 presents the results achieved by the proposed positioning system; Section 5 discusses the results presented by Section 4; and Section 6 brings a conclusion of the work presented in this paper
Summary
The current outdoor positioning systems, such as Global Positioning System (GPS) and Global Navigation Satellite System (GLONASS) are widely available in many devices in the market since the 90’s, and it has brought the possibility to know our location and the location of any devices around the world [1]. In indoor environments, some positioning methods exist, but these technologies are not so popular and/or are limited by accuracy, complexity, cost, power consumption, range, robustness and scalability [3]–[6]. This is the reason why Visible Light Communication prospects a promising solution for indoor localization systems, where the same source of light might be used for illumination, communication and positioning through the modulation of commercially available light-emitting diodes (LEDs) [7]. These advantages are reinforced by the fact that such systems can achieve high bandwidth, low latency, and high positioning accuracy using license-free spectrum immune to electromagnetic interferences [8], [9]
