“…Mobile communications have become an increasingly important part of modern life. They make it possible to perform routine tasks such as making video calls while traveling or staying in touch with family and the office from anywhere in the world [1][2][3][4]. The process of digitization began in the early 1990s with the introduction of secondgeneration cellular technologies [5].…”

The simulation of massive multiple-input multiple-output (MIMO) channel models is becoming increasingly important for testing and validation of fifth-generation new radio (5G NR) wireless networks and beyond. However, simulation performance tends to be limited when modeling a large number of antenna elements combined with a complex and realistic representation of propagation conditions. In this paper, we propose an efficient implementation of a 3rd Generation Partnership Project (3GPP) three-dimensional (3D) channel model, specifically designed for graphics processing unit (GPU) platforms, with the goal of minimizing the computational time required for channel simulation. The channel model is highly parameterized to encompass a wide range of configurations required for real-world optimized 5G NR network deployments. We use several compute unified device architecture (CUDA)-based optimization techniques to exploit the parallelism and memory hierarchy of the GPU. Experimental data show that the developed system achieves an overall speedup of about 240× compared to the original C++ model executed on an Intel processor. Compared to a design previously accelerated on a datacenter-class field programmable gate array (FPGA), the GPU design has a 33.3% higher single-precision performance but a 7.5% higher power consumption. The proposed GPU accelerator can provide fast and accurate channel simulations for 5G NR network planning and optimization.

“…Mobile communications also allows them to coordinate and communicate with colleagues and administrators on school-related matters. This ability to communicate and interact is one of the most significant benefits of using mobile technologies (Castleman, Harper, Herbst, Kies, Lane & Nagel, 2001). …”

“…In many ways, utilized appropriately and with an understanding of the potential risks, using mobile and wireless technologies deliver major benefits to all who use these technologies. However, when misused or over-used, mobile technologies and applications in the academic setting can distract students from their schoolwork and add to school-related stress (Castleman et al, 2001;Waycott & Kukulska-Hulme, 2003;Xinhao, Wei & Min, 2008).…”

This study looks at the online behavior of a hundred business management students and attempts to determine the respondents' awareness of the risks associated with the use of mobile technologies. Three questions were formulated for this study. First, when the respondents use mobile technologies, with whom do they communicate and for what purpose? The results showed that the respondents were comfortable with mobile computing and that mobile technologies were easily accessible to them. Mobile applications allowed them to complete tasks, to coordinate curricular and extra-curricular activities, and to communicate with teachers, both on a personal and a professional level. Second, what information do the respondents send or receive? Seventy-five or more of the respondents sent files and website links by email and by instant messaging. Third, are the respondents aware of the risks associated with the use of mobile technologies? Over half of the respondents were aware that using chat/IM or email without adequate safeguards could expose the school network to viruses, spyware or malware. Surprisingly, the respondents showed a lack of awareness of the potential risks that open, unsecured Bluetooth cellphone connections pose to the university's data and files. Some general recommendations are offered to help protect the institution's networks and IT infrastructure.
