“… VLC can guarantee typical requirements of vehicular safety. In literature, results can be found about experiments involving heterogeneous VLC implementation, both professional [13] and cheap ones [14], with results which can reach (at 55 MHz pulse rate), 10 Mb/s up to 20 m outdoor (with a very low BER).  Li-Fi keeps the number of nodes intrinsically limited, due to the LOS propagation of light.…”

In the last years, two main ICT enablers have been massively explored to enforce vehicular safety: GNSS-based positioning and wireless communications. In fact, by exchanging information on their respective positions, vehicles are expected to be timely aware of the hazards around them and, consequently, to be able to promptly react, hopefully decreasing the rate of accidents. Both wireless communications and positioning are unfortunately far from being ideal, especially on board: however, as recently proposed, they may both significantly benefit from the integration of the emerging Light-Fidelity (Li-Fi) technology. The paper discusses the Li-Fi perspective, shedding light on its potential benefits and issues, also with practical consideration.

“…The applications of VLC has been increasing due to the widespread use of LEDs as the light sources in indoor and outdoor environments. For example, indoor positioning systems [5], aviation [6], underwater communications [6], intelligent transportation systems [7], internet of things (IoT) [8] and camera communications [9].…”

In recent years there has been a growing interest in using organic light emitting diodes (OLEDs) for illumination in indoor environments. They offer attractive features such as flexibility and large active areas at a low cost; they are energy efficient and have higher illumination levels compared to silicone based LEDs. In addition, the utilization of OLEDs have increased in devices such as smart mobile phones and TVs because of their low thickness. This paper investigates the performance of an OLED based visible light communications (OVLC) system, using a curved and flat OLED with multiband carrierless amplitude and phase (m-CAP) modulation for m = 2 at different angles of incidence on the optical receiver. It is shown that the BER performance is improved (i.e., below the forward error correction (FEC) limit of 3.8×10-3) with the curved OLED when the optical receiver moving along a circular path for the viewing angles greater 40 o compared to the flat OLED, which is advantageous in device to device communications.

“…Moreover, NaviLight fails to perform in an environment characterized by strong sunlight, such as a building with lots of windows or skylights, because sunlight severely affects fingerprints based on visible light. The most significant drawback of existing VLP systems is the fact that they are vulnerable to sunlight noise, as the luminance of a lamp is hundreds of times lower than that of sunlight [22]. …”

Accurate indoor positioning technology provides location-based service for a variety of applications. However, most existing indoor localization approaches (e.g., Wi-Fi and Bluetooth-based methods) rely heavily on positioning infrastructure, which prevents their large-scale deployment and limits the range at which they are applicable. Here, we proposed an infrastructure-free indoor positioning and tracking approach, termed LiMag, which used ubiquitous magnetic field and ambient lights (e.g., fluorescent, incandescent, and light-emitting diodes (LEDs)) without containing modulated information. We conducted an in-depth study on both the advantages and the challenges in leveraging magnetic field and ambient light intensity for indoor localization. Based on the insights from this study, we established a hybrid observation model that took full advantage of both the magnetic field and ambient light signals. To address the low discernibility of the hybrid observation model, LiMag first generated a single-step fingerprint model by vectorizing consecutive hybrid observations within each step. In order to accurately track users, a lightweight single-step tracking algorithm based on the single-step fingerprints and the particle filter framework was designed. LiMag leveraged the walking information of users and several single-step fingerprints to generate long trajectory fingerprints that exhibited much higher location differentiation ability than the single-step fingerprint. To accelerate particle convergence and eliminate the accumulative error of single-step tracking algorithm, a long trajectory calibration scheme based on long trajectory fingerprints was also introduced. An undirected weighted graph model was constructed to decrease the computational overhead resulting from this long trajectory matching. In addition to typical indoor scenarios including offices, shopping malls and parking lots, we also conducted experiments in more challenging scenarios, including large open-plan areas as well as environments characterized by strong sunlight. Our proposed algorithm achieved a 75th percentile localization accuracy of 1.8 m and 2.2 m, respectively, in the office and shopping mall tested. In conclusion, our LiMag algorithm provided location-based service of infrastructure-free with significantly improved localization accuracy and coverage, as well as satisfactory robustness inside complex indoor environments.
