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.

Bearing in mind the high data rate and volume requirements of 5G and beyond networks, millimeter wave (mmWave) systems can be utilized with the assistance of free-space optical (FSO) systems since both technologies exhibit distinctive behaviors under different weather conditions. Therefore, in this study, we investigate a relay-based dual-hop hybrid FSO-mmWave systems from an outage performance point of view, where the communication in each hop is established on both FSO and mmWave links simultaneously. Specifically, Nakagami-m distribution is used for mmWave fading channels, while gammagamma distribution is assumed for FSO turbulence channels. Two well-known amplify-and-forward (AF) relaying schemes are examined during data transmission, in which the power amplification operation is based on partial and full channel state information of the system, namely, fixed-gain and variable-gain AF relaying methods. The effects of fundamental system variables on the outage analysis of the relay-based hybrid transmissions are investigated by obtaining exact closed-form derivations of the outage probability and effective throughput. Based upon the results, it is shown that the proposed closed-form expressions are in good match with the Monte-Carlo simulations.
