“…The last type (L 2300) used in indoor as the shopping malls and football areas. The radio frequency (RF) is used in all models to configure the communication channels [6]- [8]. The radio frequency is advantageous for establishing communication channels, but the radiation that emits from it will absorbed by human tissues, caused serious diseases [1].…”

<span lang="EN-US">Nowadays, smart devices have become a major part of human life, and this need has led to an increase in the demand for these devices, prompting major telecommunications companies to compete with each other to acquire the bulk of this market. This competition led to a significant increase in the number of mobile towers, to expand the coverage area. Each communication tower has transmitters and receivers to connect subscribers within the mobile network and other networks. The receivers and transmitters of each mobile tower operate on radio frequency waves. These waves can cause harm to humans if the body tissues absorb the radiation resulting from these waves. Headache, discomfort, and some other diseases are among the effects resulting from the spatial proximity to the mobile towers. In this paper, a model based on geographic information systems (GIS) software is proposed for the purpose of discovering the area of exposure to radio frequency radiation. This model can assists mitigate the opportunities of exposure to these radiations, thus reducing its danger. Real data of the levels of electromagnetic pollution resulting from mobile towers were analyzed during this study and compared with international safety standards.</span>

“…Additionally, 5G networks are expected to have more efficient energy consumption in comparison to previous generations. Therefore, energy efficiency is a key factor in the design of 5G networks and must be taken into consideration when optimizing the network [3][4][5]. The fifth generation of cellular networks is expected to have an increased focus on energy efficiency.…”

The fifth generation of cellular networks (5G) is seeing a rapid expansion, and energy efficiency (EE) is a hot topic of discussion. It has been found that both EE and maximum spectral efficiency (SE) are desired. They are conflicting objectives, meaning that maximizing one will decrease the other. To tackle this issue, strategies for spectrum and energy optimization have been proposed, as well as green communication plans that aim to minimize the tradeoff between SE and EE. Research has been conducted on EE-oriented resource allocations to reduce energy usage while ensuring high-quality results. To do this, the Crow Search Optimization Algorithm (CSA) has been used. Simulation results have demonstrated that this proposed method is effective in finding the most suitable solution.

“…For the research of communication systems, channel modeling plays an important role. The current research on channel model of the stratospheric platform communication system mainly focus on the issues as follows, A. M. Al-Awadi and M. J. Al-Dujaili [11] used a semi-Markov process to study stratospheric communication channels. According to different coverage positions of the stratospheric platform, the channels were divided into villages, suburbs, and urban areas to meet different probability distributions, the result of switching between Lee, normal and Rice distribution was analyzed.…”

Accelerated by the Internet of Things (IoT), the need for further technical innovations and developments within wireless communications beyond the fifth generation (B5G) networks is up-and-coming in the past few years. High altitude platform station (HAPS) communication is expected to achieve such high levels that, with high data transfer rates and low latency, millions of devices and applications can work seamlessly. The HAPS has emerged as an indispensable component of next-generations of wireless networks, which will therefore play an important role in promoting massive IoT interconnectivity with 6G. The performance of communication and key technology mainly depend on the characteristic of channel, thus we propose an efficient Markov chain based channel model, then analyze the HAPS communication system's uplink capability and swing effect through experiments. According to the simulation results, the efficacy of the proposed scheme is proven to meet the requirements of ubiquitous connectivity in future IoT enabled by 6G.
