“…A combined solution of WDM-OCDMA support massive number of simultaneous users over conventional WDM scheme and also enable dynamic add/drop function for the next generation access network [454]. The study of hybrid DWDM-MIMO FSO communications [485] is conducted aiming to increase transmission coverage with minimum BER and outage probability taking into account severe weather conditions. Despite the recent advances, more research is needed to contemplate low cost and high speed integrated FSO WDM links under different scenarios such as terrestrial, point coverage, cellular coverage, LOS, transmission range, fixed or mobile relay structure.…”

“…A study on the performance of hybrid dense wavelength division multiplexing in the multiple-input multiple-output (DWDM-MIMO) and dense wavelength division multiplexing-single input single output (DWDM-SISO) FSO systems under rain, fog and snow conditions was carried out in [16]. The atmospheric attenuation at various intensities of weather conditions were calculated using range of visibility of the atmosphere.…”

Fibreless optics or free space optical communications (FSOC) has been at the forefront of many academic research in telecommunications due to its numerous benefits of large spectrum, high-speed data transmission, security, low transmit power, unlicensed spectrum and non-interfering links. Among the technical challenges of dense deployment of small cells in heterogeneous networks (HetNet) is a flexible and cost-effective backhaul link. This paper proposes, designs, simulates and evaluates the performance of a 350 m FSOC link under different atmospheric impairments for picocell to macrocell backhauling applications. The performance of the FSOC link is assessed by evaluating bit error rate (BER), eye diagram and quality factor (Q-factor). Results obtained recommend the FSOC link deployment for pico-macrocell backhauling under the weather conditions of clear sky with/without turbulence, heavy rain, heavy haze, heavy fog and wet snow.

“…Hybrid RF/FSO systems under dry snow weather conditions were also studied. 10 Due to the fact that the attenuation depends on the rate of snowfall, the authors divided the snow into light (up to 2.5 mm/h), medium (up to 5 mm/h), and heavy (up to 10 mm/h). The attenuation caused by light, medium and heavy snow was reported as 19.3 dB/km, 50.6 dB/km, and 131.8 dB/km respectively.…”

The functionality of Free Space Optical (FSO) communication links is highly influenced by meteorological conditions such as precipitation, snowfall, and fog. In this study, we establish an FSO link and conduct experimental measurements to evaluate the link performance under extreme winter conditions in the city of Astana, with the goal of facilitating secure 5G applications. During the measurement period, the lowest recorded temperature was -19.3 °C, with an average of -7 °C. We present the path loss for a link with a distance of 212 meters under various weather conditions (snow, clear sky, cloudy, overcast), visibility, humidity, and air pressure levels. We also record wind speed and snowfall rate. The obtained path loss data is subsequently compared with analytical approximations previously reported in the literature.
