Summary: This letter studies the physical layer security of an intelligent reflecting surface aided wireless powered communication system in the presence of a passive eavesdropper, and proposes three secure IRS-WPC modes. The optimal phase shift for each mode is designed to maximize the reception of energy and information at the legitimate receiver. The accurate and asymptotic ergodic secrecy capacity of each mode is analyzed, and various new closed-form expressions are obtained. The results show that mode-I and mode-II significantly outperform the benchmark without IRS, while mode-III outperforms the benchmark without IRS under lower transmission power or small number of IRS elements.

Summary: This paper analyzes the physical layer security of an intelligent reflecting surface (IRS) in a downlink non-orthogonal multiple access (NOMA) network. The analysis considers both external and internal eavesdropping scenarios and utilizes a 1-bit coding scheme due to hardware limitations. The results provide exact and asymptotic expressions for the secrecy outage probability and effective secrecy throughput, taking into account imperfect successive interference cancellation and perfect interference cancellation. The analysis reveals that the secrecy diversity orders are related to the number of reflecting elements and there are ceilings for effective secrecy throughput in the high SNR regime. Monte Carlo simulations confirm the accuracy of the analysis and demonstrate that the IRS-NOMA scheme outperforms the IRS-aided orthogonal multiple access scheme in secrecy outage performance.

Summary: Wireless communication at terahertz frequencies is considered as a potential for future 6G wireless systems. However, secure data transmission in these systems faces complex challenges, including the less explored threat of scattering-induced eavesdropping. In this study, we investigate the security implications of scattering in non-line-of-sight (NLOS) links using metallic wavy surfaces and demonstrate real-time data transmission with a high data rate. We find that signal interception from an NLOS link can occur even with transceiver designs incorporating backscatter measures, posing a common security threat for THz communication systems with NLOS channels.

Summary: In recent years, the prevalence of wireless devices has become a significant source of electromagnetic radiation, raising concerns about the risks of long-term exposure. To address this issue, the use of rate-splitting multiple access (RSMA) has been proposed to improve wireless transmission performance while limiting electromagnetic exposure. This study focuses on optimizing transmit covariance matrices and decoding order using statistical channel state information, tackling the problem as a non-convex mixed integer program. The proposed EM exposure-aware EE maximization scheme for uplink RSMA is shown to be effective through numerical results.

Summary: This paper proposes a new scheme to enhance the secrecy performance of non-orthogonal multiple access (NOMA)-based coordinated direct relay transmission (CDRT) systems with an untrusted relay. The scheme combines physical-layer network coding (PNC) and NOMA to improve spectrum efficiency. Inter-user interference and friendly jamming signals are utilized to suppress the eavesdropping ability of the untrusted relay without compromising the acceptance quality of legitimate users. The paper investigates the secrecy performance of the NOMA-based CDRT systems, derives the closed-form expression for the ergodic secrecy sum rate, and performs asymptotic analysis to gain more insights.

Summary: This study investigates the SINR meta distribution in the uplink transmission of UAV-enabled wireless networks with inversion power control. The Matern cluster process is used to model the locations of users and UAVs within a stochastic geometry framework. The conditional success probability and moments are derived to compute the exact expression and moment matching approximation of the SINR meta distribution. The impact of power control compensation factor and UAV altitude are specifically studied, revealing that UAV altitude has a greater influence on system reliability than transmit power at low SINR thresholds due to the advantage of establishing LoS links.

Summary: This letter presents a dual-hop decode-and-forward (DF) routing protocol called hybrid relay selection (HRS) in a hybrid RF and THz relay network. The HRS protocol prioritizes THz relays for high data rates or short distances, and RF relays for low data rates or long distances. Experimental results show that the proposed HRS protocol achieves similar performance to the optimal selection protocol, which requires complete channel information.

Summary: The next generation of satellite communication systems aims to achieve terabit-per-second throughput. Free-space optical (FSO) transmission is a possible alternative that has gained increased attention in the satellite community. However, FSO communications are vulnerable to the severe effects of atmospheric turbulence. To remedy such effects, a space-air-ground (SAG) FSO network with a strategically deployed high-altitude platform acting as a relay is proposed. Furthermore, a novel SAG satellite communication network that integrates the suggested SAG-FSO transmission and conventional hybrid single-hop FSO/RF transmission is presented to improve overall system reliability and performance.

Summary: The deployment of 5G networks is in a mature phase globally, but little research has been done to compare EMF exposure and traffic levels before and after 5G activation. This study aims to provide a comprehensive assessment by conducting repeated measurements before and after 5G service. A combination of an EMF meter and a spectrum analyzer is used to measure the contribution of each pre-5G and 5G band. The results show that 5G service over mid-band frequencies has limited impact on exposure, while traffic more than doubles when 5G is activated in mid-bands. Provisioning 5G over sub-GHz bands does not substantially increase traffic levels. Additionally, changes in sight conditions and power reception due to 5G panel installation affect EMF exposure.
