Optical Wireless for Next Generation Communication

Abstract

The optical wireless communication (OWC) system link performance depends strongly newlineon the atmospheric conditions and on the link and transceiver parameters such as the link newlinerange, the operational wavelength, bit rate, transmitter power, and beam divergence newlineangle. We have studied the impact of different weather conditions along with system newlineloss, atmospheric attenuation, and rain effect of a particular location on signal power newlinereception and achievable link range. Moreover, system parameter optimization such as newlinewavelength, divergence angle, and optical power for achieving acceptable BER, Qfactor, newlineand achievable link range have been studied. newlineThe hybrid concept of free space optics/millimetre-wave technology with FNP has been newlineproposed to enable the vertical and horizontal link redundancy and to develop as a newlinesuitable complementary solution platform for next-generation communication newlinenetworks. The proposed RF/FSO backhaul system exploiting the advantages of both newlinetechnologies offers an excellent performance under different atmospheric turbulence newlineand attenuation conditions. The hybrid system with the receiver diversity technique newlineincreases the possibility of link availability in the presence of group velocity dispersion newline(GVD) and pointing errors. newline
