This work is concerned on description of the concept of distributed wireless networks based on Radio-over-Fiber technology, which is integration of wireless and fiber optic networks. The concept of RoF means to transport data over optical fibers by modulating lightwave with radio frequency signal or at the intermediate frequency/baseband. That provides to take advantage of the low loss and large bandwidth of an optical fiber together with immunity to electromagnetic influence, flexibility and transparence. A brief overview of key RoF techniques as well as comparative analysis is presented - PDF (Russian)
