A higher data rate with tolerable SNR and power requirements for 5G applications has been verified. Further, we have determined the maximum reachable link distance within acceptable performance criteria, i.e., SNR 20 dB for each desert weather conditions. The type of optical detector was used a PIN with area 1mm2 and responsively 0.4A/W for this wavelength.
The link performance and availability are investigated under the impact of clear climate and under varied dust conditions, including very light dust, light dust, moderate dust, and dense dust using signal-to-noise ratio (SNR) and total power as the key evaluation parameters. The semiconductor laser (pointer) was used as a carrier wave in free space with the specification is 5mW power and 650nm wavelength. The OFDM system provides superior performance, with a 3 dB improvement in receiver sensitivity over NRZ OOK. Free space optics system suffers from various limitations. We report the first experimental demonstration of 10 Gb/s free-space optical transmission using orthogonal frequency division multiplexing (OFDM). Free Space Optics Systems (FSO) is one of the most effective solutions, especially for atmospheric turbulence due to the weather and environment structure. Two separate 20 Gbps-40 GHz 4-QAM data bearing optical beams are transported over two distinctive Hermite-Gaussian modes HG00 and HG01, of a single-frequency laser to realize a single-channel 40 Gbps-80 GHz 5G communication link. Free space optical (FSO) communication has emerged as a viable technology for broadband wireless applications which offers the potential of high bandwidth capacity over unlicensed optical wavelengths. Optimization of free space optics parameters: An optimum solution for bad weather conditions. We propose a novel design of orthogonal frequency division multiplexing-mode division multiplexing (OFDM-MDM) based radio over free space optical (RoFSO) transceiver under the dust effect. fSONA develops and deploys Free Space Optics (FSO) solutions which use advanced line-of-sight wireless laser communications technology to enable secure, high speed bandwidth connections.
