“…Lately exploiting the TVWS spectrum from HAP is attracting a lot of interest in bridging the connectivity gap between rural and urban areas for the next generation of 5G wireless communications systems [9], [13], [21][22][23] and [29]. Due to the small space and weight of a HAP, the HAP antenna makes up a large portion of the payload, so developing the antenna with optimized parameters is critical [30].…”

The Uniform hexagonal array (UHA) sidelobe level (SLL) reduction is a crucial consideration for avoiding co-channel interference and improving Carrier-to-interference Ratio (CIR) performance in HAP wireless networks using the TVWS spectrum. The SLL reduction in UHA has been researched by applying evolutionary algorithms such as genetic algorithm (GA) and Particle Swarm Optimization (PSO). However, such algorithms have the drawbacks such as early convergence and the inability to reach globally. The beam pointing approaches for UHA antennas using Modified PSO (MPSO), for reducing the SLL on finding the optimal current weights is presented in this article. The UHA antenna array with 19 cells fitted with 169 elements in the HAPs cellular structure is considered to simulate the proposed approach. Then, the MPSO approach is employed and compared with the standard PSO algorithm and Uniform Weighting (UW) scheme. As per the simulation findings, the proposed approach drastically decreased sidelobes, with a reduction of up to -6.84dB and -13.3dB when compared to PSO and UW respectively. In other words, the proposed approach outperforms the UW and the PSO algorithms. Moreover, the CIR performance of the proposed approach has been demonstrated in terms of average outage probability and the proposed approach provides a better result.

“…It is not financially feasible for mobile service providers to establish traditional communication networks in sparsely inhabited regions. At the moment, academics and researchers from different organizations worldwide are looking into the possibility of exploiting TV White Space (TVWS), an underutilized/unused portion of the television spectrum, as a low-cost alternative to existing licensed wired/wireless broadband networks [6][7][8][9][10][11][12][13][14]. Due to its increased bandwidth, favorable propagation characteristics, building penetration, and wide coverage, the opening of TVWS for cognitive access is one of the first promising/tangible steps toward resolving rural connectivity and spectrum shortage issues.…”

“…As a result, TVWS networks are well-suited for network access in underserved/unserved regions. Recently, Geolocation Spectrum Databases (GLSDs) technologies have been highlighted as a preferred enabler for White Space Devices (WSDs) in the construction of TVWS networks to provide broadband internet access across television bands [6][7][8][9][10][11][12][13][14]. While TVWS networks benefit from their propagation characteristics and use of unlicensed bands, implementation may be time consuming and challenging due to the fact that all TVWS base stations will need backhaul connection and electricity to function.…”

As with previous generations of mobile cellular networks, rural regions are projected to face financial and technological challenges in deploying 5G services. At the time, researchers all around the world are investigating the feasibility of utilizing TV White Spaces (TVWS). TVWS is an underutilized/unused section of television spectrum that might be used as a low-cost alternative to typical licensed wired/wireless broadband networks, as well as to bridge the broadband service availability gap between rural and urban regions. A feasible alternative is to deliver TVWS services via High Altitude Platforms (HAPs) for many developed and developing nations to deliver broadband services to a large proportion of their rural and low-income populations. This article examines the advantages of utilizing TVWS spectrum from HAPs as well as the challenges connected with this type of communication architecture. This article examines the advantages of leveraging TVWS spectrum from HAPs as well as the challenges that come with this type of communication architecture. They distribute messages across a large region while monitoring and optimizing radio resource allocation, owing to their position in the sky and the centralized design of the communication system. The article assesses the performance of such a system using the IEEE 802.22 standard and the ITU-R P.452 free space path-loss model. Moreover, this article pointed out the main challenge of using TVWS spectrum from HAP system.
