“…Similarly to other communications channels, LiFi channel modeling remains a challenge. In the literature, a wide variety of channel models has already been proposed especially for indoor VLC systems [18,31,[71][72][73][74][75][76][77][78][79][80][81][82][83][84]. Conversely to the available indoor LiFi LED channels of the literature, LiFi LED street lighting channel model can safely focus on the LOS component and ignore the NLOS one as has already been analyzed in Section 2.3.…”

This paper presents a proposal for extending an existing terabit-class backbone network architecture to enable the use of LiFi technology by power utilities and smart cities. The proposed architecture provides a practical means of integrating three smart grid communication technologies—fiber optics, BPL networks and LiFi LED street lighting networks—across the transmission and distribution power grids of smart cities. In addition to expanding the backbone communications network architecture, the paper provides a comprehensive overview of LiFi technology and analyzes the concept of LiFi LED street lighting networks in a smart city. The analytical investigation of the operation and performance of LiFi LED street lighting networks focuses on the following aspects: (i) typical LED street lighting configurations and default configuration parameter values encountered in smart sustainable cities; (ii) the applied LiFi channel model and corresponding default model parameters; (iii) SNR computations and LiFi channel classifications for a variety of scenarios; and (iv) available LiFi LED street lighting network architectures for integrating LiFi LED street lighting networks with the backbone network. The paper also discusses the potential benefits of LiFi LED street lighting networks for power utilities, smart cities and individuals.

“…Although Li-Fi performs well in transfer rate, it has several limitations, including the impossibility of light passing through walls and the inadequacy of Li-Fi when used outdoors in direct sunlight or under other circumstances. Due to this, some studies, including those in [16], [33], [35], [38], and [39] have expanded on technology in general. Research [39] introduced the working of Li-Fi technology, the architecture, the modulation, the performance, and the problems viewpoints to provide a reference and expertise to design some of the Li-Fi technology.…”

“…Although the technical merits of this work have not been thoroughly examined, the piece serves as a solid starting point for more in-depth investigation. In [33] the authors performed the channel estimation for the downlink system by analyzing the illuminance distribution and received power for direct and reflected light concerning single and multiple phosphor-based white LEDs, the frontend elements, and the propagation channel of a LiFi Attocell (LAC) Network discussed Li-Fi as an indoor complement to RF communications, equipped with MATLAB simulation. The calculations and simulations of this research show that Li-Fi can serve as a complementary technology to RF communications and surpass some of its limitations, with average LOS values receiving absolute power -3.87dBm and 2.28dBm were obtained, which provide the value more above the received signal power of user equipment (UE).The previous study [16] provides a comprehensive survey study that is a great and pleasant way to begin the journey of Li-Fi discussion.…”

This paper delivers a systematic review and a bibliometric survey analysis of Light-Fidelity (Li-Fi) indoor implementation in Next Generation Network (NGN). The main objective of this study is to design a communication network based on NGN-Li-Fi for the indoor implementation which aims to increase user Quality of Service (QoS). The main merits and contributions of this study are the thorough and detailed analysis of the review, both in literature surveys and bibliometric analysis, as well as the discussion of the implementation model challenges of Li-Fi in both indoor and outdoor environments. The issue articulated in an indoor communication network is the possibility of intermittent connectivity due to barriers caused by line-of-sight (LOS) between the LED transmitter and receiver, handover due to channel overlap, and other network reliability issues. To realize the full potential and significant benefits of the Next Generation Network, challenges in indoor communication such as load-balancing and anticipating network congestion (traffic congestion) must be addressed. The main benefit of this study is the in-depth investigation of surveys in both selected critical literatures and bibliometric approach. This study seeks to comprehend the implications of Next Generation networks for indoor communication networks, particularly for visible light communication channels.

Problem: The increase in wireless devices connected to the internet, saturation of the electromagnetic spectrum used by wireless technologies based on current radio frequencies (Wi-Fi, Bluetooth, ZigBee, among others), new requirements for bandwidth, speeds and energy efficiency for the new generations of telecommunications are the cause of the birth of Li-Fi as an alternative and / or complementary technology of wireless telecommunication that is based on the visible light spectrum. Objective: The objective of this research is to expose the development of Li-Fi technology in the field of telecommunications, covering it in three main aspects such as the current state of technology, recent advances, and future projections. Methodology: Different types of bibliographic sources were used, including research and opinion articles, marketing studies, forums, books, conferences, among others with a publication date of 2012 onwards (some exceptions are found in the references); taking as selection criteria title, authors, date of publication, abstract, results and / or conclusions in relation to the research guidelines (Current Status, Advances and Future Projection of Li-Fi technology) Conclusion: The literature review article manages to highlight the importance of Li-Fi in the new generations of telecommunications of the future and its complementarity with current networks, optimally contextualizing the technology, exposing its advantages and recent advances in technical and commercial aspects as well like its disadvantages and points. weaknesses that should be addressed in the development of this technology in the future
