“…Another application of a VLC-based alarm system for mining environments is presented in [28]. Finally, several works that applied localization in mining environments based on VLC systems are presented in [29][30][31][32]. As we can see, the largest number of works related to VLC in underground mines, are security applications, location, or brief proposals of channel models that can be improved; thus, this presents an opportunity to analyze other problems present in these scenarios, such as the decrease of the ICI or the improvement of system performance.…”

“…Finally we add the coordinates' reference of P 0 , and replace Equation (20) in (31), to obtain PD i coordinates based on controllable design parameters, in the mathematical expression that follows, According to this expression, and by finding the Cartesian and angular relationship, it is possible to optimize the size of the proposed ADR based solely on its α PD i and β PD i angles; thus, trying to make it as compact and small as possible with L, considering that its application and location physics will be in a helmet of mining workers. However, this optimization is not the focus of this research, but it can be developed in future work.…”

This paper proposes two solutions based on angle diversity receivers (ADRs) to mitigate inter-cell interference (ICI) in underground mining visible light communication (VLC) systems, one of them is a novel approach. A realistic VLC system based on two underground mining scenarios, termed as mining roadway and mine working face, is developed and modeled. A channel model based on the direct component in line-of-sight (LoS) and reflections of non-line-of-sight (NLoS) links is considered, as well as thermal and shot noises. The design and mathematical models of a pyramid distribution and a new hemi-dodecahedral distribution are addressed in detail. The performances of these approaches, accompanied by signal combining schemes, are evaluated with the baseline of a single photo-diode in reception. Results show that the minimum lighting standards established in both scenarios are met. As expected, the root-mean-square delay spread decreases as the distance between the transmitters and receivers increases. Furthermore, the hemi-dodecahedron ADR in conjunction with the maximum ratio combining (MRC) scheme, presents the best performance in the evaluated VLC system, with a maximum user data rate of 250 Mbps in mining roadway and 120 Mbps in mine working face, received energy per bit/noise power of 32 dB and 23 dB, respectively, when the bit error rate corresponds to 10 − 4 , and finally, values of 120 dB in mining roadway and 118 dB in mine working face for signal-to-interference-plus-noise ratio are observed in a cumulative distribution function.

“…These scenarios comprise underground (mining, tunnels, e.g.) [28,29] and underwater environments [30], hospitals [31], and industry. Another interesting feature derived from the integration of VLC within the proposed architecture is the inherent positioning capability of this technology, which has been extensively studied in the literature [32].…”

In recent years, there has been a remarkable advance in monitoring technologies in many environments, be they urban or rural. These technologies, included in the Internet of Things (IoT) domain, allow remote control and acquisition of data from sensors for their subsequence analysis. All these systems are based on the interaction between sensors and actuators. To achieve this goal, it is necessary to provide a very high level of connectivity between the devices, especially as far as wireless systems are concerned. In this sense, there is a great variety of standards in the market of communication networks oriented to this end. One of the biggest challenges today is to allow inter-operability between these different technologies in order to homogenize this field. In addition to this, it is intended to introduce new communication techniques that can provide certain additional advantages to those already existing. The main idea is the creation of a cellular network where radiofrequency and optical technologies coexist, and whose link with the rest of the world is through long-range and low-consumption wireless technologies. The center of each cell, that is the lighting system, can be powered using solar panels, as can the existing systems in the market. The objective is that these panels are capable of providing the necessary energy to the rest of the necessary systems.

“…Meanwhile, the optical channel is convenient for short distance applications where high capacity and speed of transmission as well as low cost and practical receivers are required. Currently, there are prospective application scenarios that are being investigated using VLC technology, for example, object and people localization [6], [7], vehicle to vehicle communication [8], underwater commu-nication [9], underground mining tunnels communication [10], [11] information displaying signboards [12], communications in restricted places (hospitals, aircrafts, etc. ), Li-Fi [13], among others [14].…”

Visible light communications (VLC) is a technology that uses the unregulated electromagnetic spectrum band between 380 and 780nm which offers an enormous potential of high speed communications for short distances, regardless of radio interference. VLC technology has many useful applications, including smart lighting, high speed data link, communication in hazardous environments, vehicular communications, underwater communications, location based services, etc. Although there is a growing interest on VLC applications, there is still a lack of proper VLC channel models. In this paper, we present a comprehensive survey of modeling techniques for visible light communications with a focus on indoor wireless optical channels. For a better understanding, we select some relevant channel models and compare their characteristics from different aspects.
