The current network faces significant issues, including inconsistent coverage, limited bandwidth, and insufficient wireless connectivity, which hinder academic and administrative functions. A comprehensive assessment was conducted to identify these shortcomings, followed by the development of a detailed network design. The new design aims to enhance network coverage, increase bandwidth capacity, optimize wireless connectivity, and improve security measures. The implementation plan includes structured phases: assessment, design, installation, and optimization. This project is expected to significantly improve the user experience for students, faculty, and staff, providing a scalable and sustainable solution for future needs. The study also integrates sustainable practices and a comprehensive disaster recovery plan, ensuring the resilience and long-term viability of the network infrastructure. Background of the Study In this digital age, a robust network infrastructure is essentially the backbone of educational institutions. A well-orchestrated network not only facilitates a broad spectrum usage of educational technologies but also assures seamless connectivity whereby learners and staff access the resources effectively. Now internet access has become one of the essential resources in 7 any learning environment since learning methodologies are being integrated with more online learning using various digital tools. In a study regarding the effect of computer networking in learning institutions, network infrastructure facilitates different academic and administrative activities. These networks, however, have continued to face severe challenges in delivering coverage consistently, more so in high-density areas such as computer laboratories and classrooms. This inconsistency is more pronounced during peak usage times, leading to frequent slowdowns and connectivity drops. At present, our infrastructure does not provide uniform coverage in hightraffic areas. The existing system lacks the needed bandwidth and good equipment quality for supporting multiple devices being used simultaneously, which is why the system often slows down to a crawl or drops out entirely. These connectivity issues are a consistent problem for students that heavily affect their participation in performing activities online, accessing digital study resources, and even working on group projects. Our network infrastructure has to be redesigned because of the increase in student numbers and the availability of devices—all depending on the Internet. Most educational institutions now entirely rely upon their network infrastructure to utilize different kinds of tools for digital learning; therefore, insufficient infrastructure can significantly hamper academic performance and administrative efficiency (EDUCAUSE Library, n.d.). With further growing enrollments and uses of digital tools in the curriculum, the current limitations of the network will be realized. 8 It is due time to have a network infrastructure that can well accommodate these growing needs and provide reliable, robust, and secure connectivity across all areas of the campus. This new design will ensure that every student and faculty have a way to access resources from all areas of the building in a seamless manner, thereby fostering a more conducive learning and working environment.

Hassan and Ali (2017) explore how robust network infrastructure facilitates research collaborations, particularly in multi-campus and international settings (Hassan & Ali, 2017). Technological advancements offer promising solutions to the challenges faced by network infrastructure in educational institutions. The adoption of WiFi 6 technology significantly improves connectivity and coverage, providing faster and more reliable internet access. Jones and Smith (2020) discuss the benefits and implementation challenges of Wi-Fi 6 in educational settings 17 (Jones & Smith, 2020). Mesh networks, explored by Brown and Green (2019), enhance connectivity and performance in complex campus environments (Brown & Green, 2019). Emerging technologies like 5G have the potential to revolutionize educational network infrastructure. Zhang and Wang (2018) examine the opportunities and challenges associated with adopting cloud computing in educational settings, focusing on network infrastructure requirements (Zhang & Wang, 2018). Tokarz et al. (2020) present a case of remote laboratory infrastructure for IoT education, demonstrating the effectiveness of virtual network setups during the COVID-19 pandemic (Tokarz et al., 2020). Successful case studies provide valuable insights into the implementation of effective network infrastructure in educational settings. Vorovshchikov et al. (2020) describe a comprehensive network redesign in Moscow schools, resulting in enhanced connectivity and support for student research activities (Vorovshchikov et al., 2020). Rao and Choudhury (2012) highlight best practices in network management at NIT libraries, emphasizing the importance of regular updates and monitoring to ensure optimal performance (Rao & Choudhury, 2012). Martins and Rodrigues (2018) provide a case study demonstrating how advanced network infrastructure can enhance learning environments in a European university (Martins & Rodrigues, 2018). Perez and Diaz (2019) analyze the impact of network infrastructure on distance learning during the COVID-19 pandemic, highlighting lessons learned and future implications (Perez & Diaz, 2019). Singh and Patel (2020) evaluate the effectiveness of recent network upgrades in higher education institutions, providing data on improved performance and user satisfaction (Singh & Patel, 2020). 18 Quality network infrastructure has a direct impact on educational outcomes. Studies indicate a positive correlation between robust network systems and improved academic performance. Matthews et al. (2017) suggest that enhanced connectivity facilitates real-time information exchange, boosting productivity and fostering research collaborations (Matthews et al., 2017). Nielsen and Hansen (2018) find that improved network infrastructure enhances student engagement, leading to better academic outcomes (Nielsen & Hansen, 2018). A comparison between institutions with advanced network infrastructures and those without highlights the tangible benefits of investment in modern network systems. Chen and Liu (2020) examine the impact of network infrastructure on hybrid learning models, emphasizing the need for robust systems to support both in-person and online learning (Chen & Liu, 2020). This literature review highlights the importance of robust network infrastructure in educational institutions, the challenges that are being faced, critical technological advancements, and their impact on educational performance outcomes.
