Abstract Next generation wireless networks are the need of the hour with reliable, high bandwidth, low Bit Error Rate (BER), high Signal to Noise Ratio (SNR), large network capacity, etc. for a paradigm shift to all optical networks from the prevailing conventional electro optic network due to the various benefits of optical links such as enormous bandwidth and extremely low losses. This paper presents a primitive overview of the foregoing technologies and then move on to encapsulating the contemporary techniques to enhance the system performance. For this, preceding limitation and their respective improvement measures from literature of fiber communication and its integration with the next generation networks mainly based upon Radio over Fiber (RoF), Fiber to the Home (FTTH) and Free Space Optics (FSO) are discussed. The advancement in the domain of optical wireless communication utilizing various methodologies is summarized. Finally, we conclude by incorporating various cost reduction methodologies developed which may further be explored to make next generation networks more promising.

Abstract In this paper, simulative evaluation of the inter-aircraft optical wireless communication system with the use of different modulation formats like return to zero (RZ), non return to zero (NRZ) and raised cosine by signal to noise ratio (SNR) and quality factor (Q-factor). Performance parameters are attenuation level, transmitting pointing error and scintillation are used to analyse the performance of the system. Including the pre- and post-amplifier configuration in the system, a link range of 100 km is achieved at an acceptable bit error rate and the performance of the system is also enhanced at a 5 Gbps data rate as compared to the earlier detection mechanism.

AbstractThis study has presented the complete comparison non return to zero (NRZ) and return to zero (RZ) modulation techniques for upgrading long haul optical wireless communication systems. Electrical signal to noise ratio is measured. Q-ranges factor are measured at the receiver side for different transmission distance from 500 to 1000  km. As well as the performance parameters of optical wireless communication systems are estimated at different transmission data rates with possible maximum transmission distance. NRZ modulation technique has outlined better performance than RZ modulation technique for upgrading optical wireless communication systems.

In metropolitan communication infrastructures a revolutionary technique is emerge known as terrestrial optical wireless communication (OWC), which makes a high-rise building connection is possible. Even with this solution, there are many other problems like the influence of haze and fog in the propagation channel which obstruct and scatter OWC propagation light and consequently led to a big attenuation, due to propagate in temporal, angular and spatial of the light signal. Not to mention the minimum visibility that discourages the implementation of the pointing errors (PE) and tracking system. This present work aims to analyze the interrelation between multiple scattering (dense fog, heavy fog, light fog, heavy haze and light haze) and receiver PE under modified duo-binary return-to-zero (MDRZ) system. We found that PE caused by beam swag is the main controlling factor and industriously minimize the link margin, signal-to-noise ratio (SNR), and raise the bit error rate (BER) when there is an increasing the turbulence strength and the track length. We recommended to guarantee transmitter– receiver alignment by installing a variable field of view (FOV) receiver (a tracking system) to overcome the scattering impact of the fog that make render urban laser communication effective in the presence of PE.

Indoor Optical Wireless Communication

Abstract The existing radio frequency technologies face the bandwidth limitation due to the increase in the number of devices being used inside the indoor environment. though, the backbone networks are capable of carrying a large amount of data to the tune of several hundreds of gigabits per second, the last mile techniques, especially the indoor connectivity, continue to pose a challenge in terms of handling large data capacity. The indoor optical wireless communication could be one such promising technology that is potentially capable of handling large amount of data transmission within the indoor environment. The receiver mobility may largely affect the key communication parameters which undergo spatial variations. Therefore, in this paper, we investigate several parameters especially the channel capacity, bit error rate, received pulse power, pulse delay spread and signal-to-noise ratio pertaining to receiver mobility.
