“…On the contrary, the use of RGB LED as a receiver can mitigate this problem as they have a lower detection bandwidth without the need of using extra devices and filters. In our study, we experimentally show that, similar to single LEDs [8], commercial RGB LED bulbs that are designed for artificial illumination can be used as a light-sensing device in a narrow band of wavelengths close to the band of emission. For instance, we show that the green chip of RGB LEDs is sensitive to frequencies in the visible green band.…”

“…Besides, the LED used as receivers does not have proper optics to receive light, and their field of view (FOV) should be broad and independent of the photodetection area. However, due to being photosensitive devices, they can perform as photodetectors [8]. Manufacturers do not provide information related to spectral sensitivity, FOV, and the effect of temperature on responsivity, which can affect the performance of RGB LEDs as a receiver.…”

RGB LED bulbs have entered the market as a promising alternative to traditional phosphor coating LEDs to meet illumination standards. In this paper, we introduce and propose solutions to address the challenges of RGB LED lighting for the Internet of Things applications, performing communication, harvesting energy and sensing tasks. Through experiments, we demonstrate that we can use RGB LEDs for multiple tasks. We can achieve a bandwidth in the order of 50 kHz and distances of around 3.5 m using commercial RGB LED bulbs as transceivers, without using any dedicated photodetector. RGB LED links are composed of three main colours, and we show that red is the best colour both for communicating to another receiving RGB LED bulb, as well as for harvesting with a solar cell; green and blue can instead be exploited for standard-compliant lighting and/or sensing purposes. We evaluate the system in two proof of concepts and provide insights for operating RGB LEDs for multiple tasks.

“…The versatility of the lighting system lies in its ability to serve as an ideal vehicle for VLC technology, paving the way for the development of various Internet of Things (IoT) applications. By blending the potential of smart sensors with lighting, it becomes possible to create cutting-edge IoT solutions that are both unique and resourceful [33]. Notably, the lighting system can revolutionize several urban applications, from creating smart homes to building energy-efficient offices and even revolutionizing urban infrastructure through smart streetlights.…”

The expectation for communication systems beyond 5G/6G is to provide high reliability, high throughput, low latency, and high energy efficiency services. The integration between systems based on radio frequency (RF) and visible light communication (VLC) promises the design of hybrid systems capable of addressing and largely satisfying these requirements. Hybrid network design enables complementary cooperation without interference between the two technologies, thereby increasing the overall system data rate, improving load balancing, and reducing non-coverage areas. VLC/RF hybrid networks can offer reliable and efficient communication solutions for Internet of Things (IoT) applications such as smart lighting, location-based services, home automation, smart healthcare, and industrial IoT. Therefore, hybrid VLC/RF networks are key technologies for next-generation communication systems. In this paper, a comprehensive state-of-the-art study of hybrid VLC/RF networks is carried out, divided into four areas. First, indoor scenarios are studied considering lighting requirements, hybrid channel models, load balancing, resource allocation, and hybrid network topologies. Second, the characteristics and implementation of these hybrid networks in outdoor scenarios with adverse conditions are analyzed. Third, we address the main applications of hybrid VLC/RF networks in technological, economic, and socio-environmental domains. Finally, we outline the main challenges and future research lines of hybrid VLC/RF networks.

“…LEDs, on the other hand, maybe utilized as both a transmitter and a receiver in situations where cost is a major factor. In comparison to other light detection sensors, LEDs are sensitive to a small range of wavelengths, are resistant to sunlight interference, and are readily accessible [136].…”

<p>The number of connected mobile devices and Internet of Things (IoT) is growing around us, rapidly. Since, most of the people daily activities are relying on these connected things or devices. Specifically, this past year (with COVID-19) changed daily life in abroad and this is increased the use of IoT enabled technologies in health sector, work, and play. Further, the most common service via using these technologies is the localization/positioning service for different applications including: geo-tagging, billing, contact tracing, health-care system, point-of-interest recommendations, social networking, security, and more. Despite the availability of a large number of localization solutions in the literature, the precision of localization cannot meet the needs of consumers. For that reason, this paper provides an in-depth investigation of the existing technologies and techniques in the localization field, within the IoT era. Furthermore, the benefits and drawbacks of each technique with enabled technologies are illustrated and a comparison between the utilized technologies in the localization is made. The paper as a guideline is also going through all of the metrics that may be used to assess the localization solutions. Finally, the state-of-the-art solutions are examined, with challenges and perspectives regarding indoors/outdoors environments are demonstrated.</p>
