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.

“…By performing the proposed analysis, it is shown that the numerical values, which have been used in the simulation results of [13], are realistic values in terms of the link distance and FSO/RF antenna/aperture parameters. We can rewrite β as, where, g N 0 can be estimated and then for a fixed value of β, T frame n is calculated using (18). With the help of (19), g λ is calculated for a given β.…”

“…Other better solution is to overcome the issues of FSO communications have been done in the literature by many researchers [16]- [23]. Authors in [17], [18] evaluate the performance of hybrid FSP/RF communication system considering the multiple RF antennas with the mmW RF channel. It is seen from [18], [19], [24] that using more than single RF antenna improves the system performance.…”

Hybrid Optical-Radio Transmission System Link Quality: Link Budget Analysis

2020

From the last few decades' radio frequency (RF) spectrum remained attractive for wireless/wire-line applications. RF spectrum becomes dense and occupied, which makes its availability difficult to other broadband channels. Free space optical (FSO) communication, which was used for messaging/indication in the ancient days, now becomes more popular and attractive in the new era. The popularity of FSO is due to its freely available large spectrum, inherited secure links and ease of deployment. However, FSO link has to face certain challenges, e.g., line-of-sight (LOS) requirement, link attenuation due to atmospheric turbulence and severe weather conditions. To overcome the issues of FSO communication, hybrid optical-radio transmission system is proposed by which we can get maximum benefits of both spectrum. Considering the proposed transmission system link quality, link budget analysis is done in the presented work. Link budget design of transmission system is important to analyze and give recommendations.
