In this paper, the effect of Long-Range wireless technology parameters on signal propagation in suburban environments is investigated. Wireless propagation modeling provides information about the wireless channel and its impact on communication links. Received signal strength and coverage area are evaluated to determine signal path loss. The operating frequency of 433 MHz Long Range Wireless Area Network is utilized with different spreading factors, bandwidths, and code rates. Empirical propagation models are utilized to predict a mathematical model based on measured empirical signal strength in a suburban site in Baghdad City. The measured signal strength and signal-to-noise ratio values were obtained through drive tests in an Internet of Vehicles environment to design a network that could accurately report vehicle locations. The LoRa parameters affected the calculated path loss exponent, leading to various predictions in the network design. The path loss exponent exhibited instability due to the presence of obstacles and different long-range parameter settings. Path loss exponent deviation fluctuates due to bandwidth and spreading factor variations. Path loss exponent reduced at higher coding rates for more protection purposes. Packet ratio reception improved as the coding rate increased. To minimize the impact of the path loss on network design, an optimization policy was employed to determine the best parameters that resulted in the lowest path loss. The optimal path loss obtained at LoRa configuration parameters settings with spreading factor (7), bandwidth (500 kHz), and code rate (4/5).

Newly, the utilization of polypropene for packaging consumer products was populated significantly, which might make ecological problems. So, it is substantial to detect environmentally friendly techniques to recycle these waste substances without causing any environmental risks. One such technique could be the utilize poly wastes as stabilizer agents for soils. In the current investigation, textiled-poly bags (TPB) have been recycled and fabricated to be economy and environmentally-friendly fibers. The impact of utilizing different proportions and lengths of these fibers on the mechanical features of clayey soil has been evaluated. The investigation depended on four different fiber-proportions (1, 2, 3, &4)% of soil weight in two different lengths (1&2) cm. Geotechnical experimental test consequences demonstrated that the recycled fiber pieces minimize the optimum dry density (ODD) and the corresponding optimum water content (OWC) of the treated soil samples. Additionally, there was a notable increment in the uniaxial compression test results of the treated soil samples. Moreover, the consequences of California Bearing Ratio tests showed that the utilization of recycled TPB fibers in clayey soil samples enhances the resistance and deformation performance of the soils specially when utilizing 4% of recycled TPB fibers for both lengths (1 & 2) cm.

The high speeds resulting from the use of millimeter waves (mmWave) in 5G mobile networks are accompanied by high path loss. The issue of generating a reliable propagation model of radio waves is crucial to the development of cellular networks since it reveals essential information regarding the properties of the wireless channel. The received signal strength, the coverage area, and the outage probability in certain places may all be determined through theoretical or empirical radio frequency propagation models, which offer essential valuable information regarding signal path loss and fading. This work analyzes a comprehensive three-dimensional ray-tracing method at 28 GHz for Najaf city, Iraq. The optimum path loss model for the city of Najaf is evaluated using the close-in (CI) model. On average, the values of the main parameters of CI model n n , X σ CI {X}_{\sigma }^{{\rm{CI}}} accomplished, respectively, 3.461866667 and 11.13958333. The lowest achievable path loss exponent was 3.0619 across all analyzed scenarios, while the highest possible value was 4.1253. The results of this work can serve as a baseline for mmWave measurement campaigns conducted in comparable conditions, and they provide a new avenue for future research into mmWave at 28 GHz in Iraq.
