A Survey on Radio over Fiber (RoF) for Wireless Broadband Access Technologies [PDF]

open access: yesInternational Journal of Computer Applications, 2013
this paper presents a survey on RoF for Wireless Broadband Access technology like WiMAX (Fixed and Mobile). RoF is considered to achieve an effective delivery of wireless and baseband signal, and it also reduces the power consumption. In the other hand WiMAX (Worldwide Interoperability for Microwave Access) is recent fast growing broadband access ...

Integration of radio over fiber (RoF) with fiber to the home (FTTH) schemes [PDF]

open access: yes, 2021
Two integrating techniques and topologies for fiber optic network systems such as RoF and FTTH have been studied and presented in this project. Two digital signals with data rate 622Mb/s and 1.25Gb/s are considered as the two service signals to be hybrid.
