Abstract
Wireless mobile communication is entering the era of 5G technology very rapidly. This increasing demand for wireless communication is basically due to very simple installation and maintenance as compared to other wired network technologies. Therefore, rapidly increasing demand for broadband and high-speed mobile communication requires a very high-speed network which fulfils all the requirements of growing broadband wireless services. The only promising solution of the future wireless high-speed mobile communication is transmission of Radio Frequency (RF) signals on optical fiber. This results in a very high-speed network called Radio over Fiber (RoF) network, which is basically a combination of wired network and wireless services, in which RF signal is transmitted over the optical fiber by modulating the light with RF signal which contains the required information. RoF technology has become the backbone of the future broadband 5G wireless network. For RoF architecture, improvement in RoF link performance is the most challenging feature. In this paper, an overview of RoF architecture is elaborated with various RoF link performance improvement techniques. The comparison in terms of advantage and limitation of every performance improvement technique is summarized. The paper concludes with various research opportunities available in this area.
Introduction
As low frequency radio spectrum is getting overcrowded due to a large number of high bandwidth applications, higher radio frequency spectra which lie in the range of millimeter waves are used. These high frequencies (in the range of 40-60 GHz) have very high bandwidth. To provide wireless service to a large number of users, existing larger cells are split into smaller cells; therefore, for seamless coverage, Radio Access
