Abstract:Increased capacity, higher data rate, decreased latency, and better service quality are examples of the primary objectives or needs that must be catered to in the near future, i.e., fifth-generation (5G) and beyond. To fulfil these needs, cellular network design must be drastically improved. The 5G cellular network design, huge multiple-input multiple-output (MIMO) technology, and device-to-device communication are all highlighted in this comprehensive study. Hence, free-space optics (FSO) is a promising solution to address this field. However, FSO standalone is insufficient during turbulent weather conditions. FSO systems possess some limitations, such as being able to be disturbed by any interference between sender and receiver such as a flying bird and a tree, as it requires line-of-sight (LOS) connectivity. Moreover, it is sensitive to weather conditions; the FSO performance significantly decreases in bad weather conditions such as fog and snow; those factors deteriorate the performance of FSO. This paper conducts a systematic survey on the existing projects in the same area of research such as the hybrid FSO/Radio frequency (RF) communication system by listing each technique used for each model to achieve optimum performance in terms of data rate and Bit Error Rate (BER) to be implemented in 5G networks.Keywords: fifth-generation (5G); multiple-input multiple-output (MIMO); free-space optics (FSO); line-of-sight (LOS); hybrid FSO/radio-frequency (RF)
Prof. Derawi is currently having a dual-career acting as the youngest professor of Norway and an extremely true innovator. He received his diplomas in Computer Science engineering from the Technical University of Denmark (DTU, Denmark) where he received both a BSc (2007) and Msc (2009) degree. In addition, he received the title as the youngest engineer of Denmark in 2009. Derawi has pursued his PhD in information security at the Norwegian Information Security Laboratory (NISLab), Gjøvik University (now NTNU, Norway). In the beginning of his PhD studies, he was a visiting researcher at the "Center for Advanced Security Research Darmstadt" (CASED, www.cased.de), Germany. His PhD research interest included smart mobile technologies and also biometrics with specialization on behavioural biometric recognition in mobile devices. Derawi was active in several European and national projects as well for the since 2009. Today he holds a professorship within electrical engineering and is specialised within information security, e-health, autonomous systems, biometric systems, wireless communications, IoT, digital fundamentals micro-controllers. He is also the head of the "Smart Wireless Systems" Research group at the Department of Electronic Systems (NTNU, Norway).
