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