Chile is the largest copper producer in the world. In the world, almost 40% of copper is produced underground and it is expected that the activity will reach the 60% of the total mining activity. Because of this, there will be new challenges in terms of safety and productivity. Visible Light Communications (VLC) is a new technology capable to provide illumination and communication at the same time. This technology has shown high accuracy in localization and tacking for indoor scenarios. Nevertheless, most of the applications that can be found in literature assumes square rooms, no tilt receivers, and Line of Sight (LOS) link. In this paper we will address the problem of enabling Visible Light Communications (VLC) based Indoor Positioning System (IPS) in underground mines. Feasible link configurations and positioning topologies are studied throughout this paper. In addition to this, different localization methods are classified in two groups, i.e., range based and range free methods. Their performance in terms of accuracy and robustness as well as the constraints of each method will be analyzed for its usage in underground mines.

“…On the other hand, by leveraging illumination infrastructures, it was possible to develop a cost effective and accurate underground positioning system. The research [119] proposed a 1-D VLC-based positioning system where an OOK modulation was adopted to represent a LED lamp's ID. The signals were received by PD, whose position was estimated using the proximity algorithm.…”

As Global Positioning System (GPS) cannot provide satisfying performance in indoor environments, indoor positioning technology, which utilizes indoor wireless signals instead of GPS signals, has grown rapidly in recent years. Meanwhile, visible light communication (VLC) using light devices such as light emitting diodes (LEDs) has been deemed to be a promising candidate in the heterogeneous wireless networks that may collaborate with radio frequencies (RF) wireless networks. In particular, light-fidelity has a great potential for deployment in future indoor environments because of its high throughput and security advantages. This article provides a comprehensive study of a novel positioning technology based on visible white LED lights, which has attracted much attention from both academia and industry. The essential characteristics and principles of this system are deeply discussed, and relevant positioning algorithms and designs are classified and elaborated. This article undertakes a thorough investigation into current LED-based indoor positioning systems and compares their performance through many aspects, such as test environment, accuracy, and cost. It presents indoor hybrid positioning systems among VLC and other systems (e.g., inertial sensors and RF systems). We also review and classify outdoor VLC positioning applications for the first time. Finally, this article surveys major advances as well as open issues, challenges, and future research directions in VLC positioning systems.

“…Only one node position is tested and studies about the error distribution are not carried out. In [17] a cell ID VLC positioning system for underground mines is proposed. Using the proposed method different levels of accuracy can be obtained depending on the coverage area of each cell and the separation between each other.…”

In this paper we present a novel range free method based on connectivity for homogeneous optical wireless networks. Optical attocells deployed homogeneously within an indoor scenario send periodically its position and network architecture information. The mobile node (MN) uses this information in order to self-determine its position by means of solving different convex optimization problems. As a result of this procedure, the feasible localization area is reduced to a convex polygon. A square room of 2.4 meters width and 2.4 meters large with 9 LED lights placed in the ceiling is modeled as the proposed scenario. Our method is compared with two connectivity-based range free algorithms in terms of accuracy. In addition to this, robustness of the method is evaluated using different values on the receiver's Field of View (FOV). Numerical results show that the proposed method outperforms the connectivity based methods in terms of accuracy and robustness.
