“…All these devices are connected to the Internet and consumes data through numerous applications. Furthermore, introduction of Internet of Things (IoTs) have evolved the mode of communication such that Internet is no longer used to connect humans but is also facilitating communication between machines and devices [10][11][12][13][14][15]. All these factors have not only multiplied the demand for bandwidth, but also created a very dense network of interconnected devices that requires a very large and dense Access network connecting these devices to the core or backhaul network.…”

“…The massive deployment of RRH in order to provide the services promised by 5G networks makes the front hauling complex [11,13]. Furthermore, deployment of such a large number of RRHs will increase the utilization of optical fiber media by 10-folds that entail heavy civil work and massive capital expenditure (CAPEX) [13,15]. Moreover, deployment of optical fiber media in densely populated localities is second to impossible.…”

This paper presents high altitude platform free space optics (HAP-FSO) channels using various filtering operations for fifth generation (5G) system. Performance analysis is done utilizing different types of optical filters such as Bessel, Trapezoidal, Gaussian and Rectangular. A comparison is carried out between our proposed scheme and reported counterpart. HAP-FSO performances have been investigated by referring to different factors such as transmission distance, transmitting aperture diameter, beam divergence, transmitter aperture diameter, and receiver diameter. Simulation analysis is carried out in highly recognized software tool called Optisystem to validate the implementation and performance of the proposed system. It is found that the most extreme quality services can be accomplished via utilizing Gaussian optical channel in comparison with distinctive optical channels. Simulation results also confirm the proposed system for error free transmission at bit error rate (BER) of 10 -9 for all types of filters at 10Gbps with in favor to Gaussian filter for the same number of users.

“…To connect a high number of devices within a cell, wireless networks, like 3G and 4G, rely heavily on base stations with wireless connectivity. However, these networks cannot handle the increasing number of linked devices and the bandwidth they need [1][2][3][4][5]. Furthermore, regular radio communication links, like radio frequency (RF) and microwaves, are interference limited.…”

“…The fundamental configuration of CRAN comprises three key elements: a baseband unit (BBU) pool housing numerous BBUs equipped with centralized processors, radio units (RUs) housing antennas positioned at the cell site, and a front-haul network linking RUs and BBUs through high-capacity, low-latency connections [7]. The design of the front-haul network to provide a high-capacity, low latency network with cost and energy efficiency has been one of the most significant design challenges on the road to 5G, beyond 5G (B5G), and 6G realization because these networks require dense deployment of RUs near the subscriber premises [2][3][4][5][6][7].…”

With the expansion of Information and Communication Technology, it is important to develop a communication network that can provide high-capacity ubiquitous connectivity. This work proposes an energy-efficient passive optical network (PON) using orthogonal frequency division multiple access (OFDMA) and wavelength division multiplexing (WDM) to facilitate the dense deployment of radio units (RUs) in a beyond 5G (B5G) communication network. High-speed connectivity is ensured by employing a hybrid PON architecture that includes a combination of free space optics (FSO) links and optical fiber (OF) media to carry OFDM and WDM multiplexed traffic. Furthermore, an optical frequency comb generator (OFCG) is utilized at the transmitter module to generate and leverage the spectrum for transmitting information from baseband units (BBUs) to the RUs situated near the end users. The proposed system is analyzed through (i) simulation analysis using Optisystem for transmission capacity computations and (ii) mathematical analysis to determine the total savings in energy. The simulation analysis shows that the given architecture can carry data across 3 km of FSO medium using 512 subcarriers per BBU transmitting at 10 Gbps of data with QPSK-modulated bit sequence. Additionally, energy efficiency shows that the use of an OFCG cuts the total energy usage by 22% at the transmitter module without negatively impacting the system’s high cardinality and transmission capacity.
