Abstract
Objectives: To find out how fiber distribution system could be utilized for 5G based futuristic higher capacity and lower latency front haul transmission system. Findings: Integrating the transmission of Millimeter wave (Mm wave) signals over the Radio over Fiber (RoF) system i.e. Mm-RoF can be seen as a promising candidate that would satisfy the requirement imposed by 5G wireless system. Further, optical generation of Mm wave signals is a major concern that needs to be taken care of and some appropriate hybrid photonic generation methods should be employed for Mm wave signal distribution over the RoF system that incur lower installation cost and higher transmission performance. Applications: This will enrich the researchers with valuable content on single platform and motivate them to undertake the research work towards the advancement in the photonic generation of Mm wave signals over the RoF network for 5G applications with reduced system cost and complexity. Keywords: Radio over Fiber; Mm-wave technology; 5G networks; optical signal generation; Mm wave based RoF etc
Highlights
Due to the rapid rise in data traffic for portable devices and its global expectation will grow about eight times by the end of the year 2023 as new multimedia applications for instance ultra high definition (UHD) video streaming, virtual and augmented reality (AR) and evolving industrial use etc. involve higher bandwidth, higher capability and reduced latency around 1 ms enabling the researchers to look for new spectrum beyond 4G standard, giving rise to the transition towards the new generation i.e. 5G cellular network (1).Further, 5G would push through other technologies to a level such as the Internet of Things (IoTs), games, smart city, smart home, self-driving cars, remote operations, machine learning etc. (2)
The Mm wave based Radio over Fiber (RoF) system was found to be a prominent solution for transmitting high frequency signal with low drive voltages in the futuristic networks as it has a great potential to support secure, cost effective and high capacity wireless access for broadband and multimedia wireless services
The various different Mm wave optical generation techniques utilized over the past for transmission has been evaluated and presented and some performance improvement parameters with the related techniques employed with reducing cost strategies were presented and was found that there is a trade off lying between system performance and cost reduction as enhancing the system performance enhances its cost and complexity

There are challenges prevailing in the path of the wireless service providers to provide a more efficient technology that would provide higher data rates in order to tackle the worldwide bandwidth shortage so as to efficiently utilize the electromagnetic spectrum. This cellular technology transition is almost instantaneously opening up a new world of linked applications(3). The technology roadmap expands to the LTE-advanced (LTE-Adv.) network to satisfy the requirement of maximum throughput levels exceeding 1 Gb/s. The backbone network design of this generation will help in migrating from coaxial cable to optical fiber to mm wave wireless links (1) (3)
