Relative Investigation of Methods to Generate Millimeter Wave in Radio-Over-Fiber Communication

Abstract

Integration of fiber and wireless (Fi-Wi) technology in latest communication has brought massive improvements in terms of high data rate, low interference and attenuation. The frequency range of 30–300 GHz (millimeter wave) is capable of generating orders of magnitude greater bandwidth. Merging two concepts fiber communication has large bandwidth capacity and wireless coverage are combining both features also became an emerging platform for Internet providers for ever-increasing bandwidth hungry. Bandwidth and channel capacity can be improved by increasing frequency range and implementing wavelength division multiplexing (WDM). Direct and indirect modulated waves imposed with signal generator at transmitter side to generate millimeter (mm) wave. Phase modulator (PM) and Mach–Zehnder modulator (MZM) based techniques of generating mm-wave are investigated and results are shown for various input sine wave generators and different fiber wavelengths.
