“…This trend continues, and today, the overwhelming majority of wireless communications exploit radio waves. Indeed, radio frequency (RF) communications have become an integral part of our life but the rapidly increasing number of devices entering the network, which could be in billions by 2020, is leading toward a spectrum crunch . This has motivated research in alternative transmission technologies, such as wireless communications exploiting light.…”

“…Indeed, radio frequency (RF) communications have become an integral part of our life but the rapidly increasing number of devices entering the network, which could be in billions by 2020, is leading toward a spectrum crunch. 1 This has motivated research in alternative transmission technologies, such as wireless communications exploiting light. Indeed, recent advancement in optoelectronics, particularly the development and further improvement of white light-emitting diodes (LED), have created an attractive approach to send information wirelessly, namely, optical wireless communication (OWC).…”

In this paper, we propose a reconfigurable optical‐radio wireless network characterized by high flexibility and performance. The hybrid network can be dynamically configured, adapting itself to the changing requirements of users or operating environments, dynamics of the transmission medium, and availability of resources. First, the basic concept, system architecture, and key operating modes are introduced. Possible operating scenarios and their relationship to the operating modes are discussed. Then, a practical implementation of the hybrid network is introduced, describing the network components, architecture, modulation scheme, and implementation technologies. Implementation was carried out using mostly off‐the‐shelf components and universal software radio peripheral blocks. Particular attention has been put in implementing a fast handover mechanism between modes, an essential requirement for seamless network reconfiguration. Network performance is evaluated and different switching approaches are compared. The paper demonstrates practically the proposed concept based on dynamic system reconfiguration. For the implementation, a mode switching algorithm was developed making decisions based on the quality of the wireless channels. The system was tested with live video packets transmitted through the network. System performance was assessed through data throughput and packet loss measured for different modulation parameters. The proposed concept, essentially a software‐defined hybrid network, is flexible and makes efficient use of radio resources. Moreover, the network has the potential to achieve high performance. All these characteristics make reconfigurable optical‐radio networks an attractive candidate for fifth generation and beyond.

Resource allocation and interference management are two main issues that need to be carefully addressed in visible light communication (VLC) systems. In this paper, we propose a resource allocation scheme that can also handle the intercell interference in a multi-user VLC system that employs orthogonal frequency division multiple access (OFDMA). Particularly, we suggest dividing the cell coverage into two non-overlapping zones and performing a two-step resource allocation process, in which each step corresponds to a different level of allocating resources, i.e., zone and user levels. We initially define both zones in terms of the physical area and the amount of allocated resources and we investigate the impact of illumination requirements on defining both zones. Through simulations, we evaluate the performance of the proposed scheme in terms of the area spectral efficiency and the fairness level between the two zones. We show that both performance measures can be potentially enhanced by carefully setting a certain design parameter that reflects the priority level of the users located in the region around the cell center, denoted as Zone 0, in terms of the achievable rate. We further eventuate the system performance in a realistic transmission ✩ scenario using a simulation tool.Recently, the noticeable advances in white light emitting diodes (LEDs) technology motivated utilizing the visible light spectrum for data transmission along with the white LEDs main function of illumination [6,7,8,9,10,11].In addition to providing the required bandwidth, using white LEDs for data transmission has many advantages over the RF technology. For example, they are cheap, energy efficient and no extra infrastructure is needed since white LEDs would be already installed for lighting. Furthermore, using white LEDs for data transmission would inherently ensure data security since light does not propagate through walls.

“…This approach will lead in the long run to reduced cost, greener environment and the release of highly need RF frequency spectrum for other applications. VLC (in the spectrum range of 380 to 780 nm) has attracted the attention of many researchers in the last decade with dedicated IEEE 802.15.7r1 standard [7], which defines network architectures, physical and medium access control (MAC) layers. The LED light sources adapted are characterized mostly by their lower power consumption, relatively higher energy efficiency, switching capability and much wider bandwidth compared to the incandescent and fluorescent lights.…”
