“…It is primarily to assist wide bandwidth range over a long distance communication [10]. Although at high bandwidth, long distance cost efficient communication the environmental factors such as weather linked factors continue as major challenges to minimize and may limit the data rate and link availability via LOS (Line of Sight) [11]. Recent studies suggest ways to solve LOS line of sight problems with minimal bit-error-rate (BER) performance in FSO communication system under worst interference conditions [12].…”

Abstract. In this paper, the performance of downlink design utilizing the free space optic (FSO) is presented. The permissible BER of 10 -58 is achieved when the system utilized 40 cm aperture diameter. The highest system sensitivity will lead to less error and enable more transmission output. The result revealed, at a bit rate 155Mbps and effective received power -27.5 dBm, FSO downlink system at bit rate 155 Mbps improved by 13% as compared to 1.5 Gbps and 2.5 Gbps in single transmission line. It is truly shown that, the FSO system utilized 155 Mbp/s with 40 cm aperture diameter shown good performance of a reliable FSO downlink system.

“…From a commercial perspective, outdoor OW complements optical fibers in LAN interconnections and broadband access networks, providing a high-bandwidth and low-cost alternative [149]. The installation of an outdoor OW system alleviates the most significant expenditure of fiber deployment: the digging up and repairing of roads.…”

This article presents an overview of optical wireless (OW) communication systems that operate both in the short-(personal and indoor systems) and the long-range (outdoor and hybrid) regimes. Each of these areas is discussed in terms of (a) key requirements, (b) their application framework, (c) major impairments and applicable mitigation techniques, and (d) current and/or future trends. Personal communication systems are discussed within the context of point-to-point ultra-high speed data transfer. The most relevant application framework and related standards are presented, including the next generation Giga-IR standard that extends personal communication speeds to over 1 Gb/s. As far as indoor systems are concerned, emphasis is given on modeling the dispersive nature of indoor OW channels, on the limitations that dispersion imposes on user mobility and dispersion mitigation techniques. Visible light communication systems, which provide both illumination and communication over visible or hybrid visible/ infrared LEDs, are presented as the most important representative of future indoor OW systems. The discussion on outdoor systems focuses on the impact of atmospheric effects on the optical channel and associated mitigation techniques that extend the realizable link lengths and transfer rates. Currently, outdoor OW is commercially available at 10 Gb/s Ethernet speeds for Metro networks and Local-Area-Network interconnections and speeds are expected to increase as faster and more reliable optical components become available. This article concludes with hybrid optical wireless/radio-frequency (OW/RF) systems that employ an additional RF link to improve the overall system reliability. Emphasis is given on cooperation techniques between the reliable RF subsystem and the broadband OW system.

“…Recently, OWC has increasingly attracted much attention for the last mile access environment due to its merits such as the large bandwidth, low cost, no licensing requirements, and high security [1][2][3]. OWC also can be adopted in order to offer higher data rates and provide seamless data services to the passengers traveling by train, buses, and ships [4], thereby increasing the demand of high-speed wireless access under the moving conditions.…”
