Development of 5G Mobile Network Technology: Its Benefits, Security and Limitations

Abstract: Fifth Generation (5G) network technology is the forthcoming step of mobile communication that will provide rich ubiquitous communication infrastructure with wide range of high-quality services by 2020-2025 in several countries. In modern information society, people use real-time interactive e-government services, advanced e-health diagnostics surrounded by Internet of Things services or participates in mass cultural events through high-quality digital media. To cope with ever-increasing demand for higher data rate and increase in the number of users, wireless networks have recently witnessed a tremendous growth in the data traffic. It is envisioned that 5G communication will offer significantly greater data bandwidth and almost infinite capability of networking resulting in unfaltering user experiences for virtual/augmented reality, massive content streaming, user-centric computing, crowded area services, smart personal networks, Internet of Things (IoT), smart buildings and smart cities, etc. Advanced studies on 5G mobile technology are mostly related to the development of World Wide Wireless Web (WWWW) allowing the execution of a highly flexible network such as Dynamic Adhoc Wireless Network (DAWN). This 5G technology will make use of IPv6, Flat-IP and VOIP (Voice over IP) network technologies, which will provide improved data rates, increased spectrum efficiency and will support ubiquitous computing. Moreover, 5G aims at utilizing many promising network technologies and it will also support a huge number of connected devices integrating above mentioned advanced technologies. On the other hand, these innovating techniques will certainly bring tremendous challenges for security, privacy and trust. Therefore, secure network architectures, mechanisms and protocols are required to address the problem of securityby- design as well as also security-by-operations rules. Due to high radiation of electromagnetic fields in cumulative 5G networks, health problems may also arise. Bandwidth access and sharing could be other concerned issues, since the current bandwidth is not enough for the expected massive use of the mobile infrastructure. Thus, new technical insights/ideas presenting the challenges faced by 5G deployment as well as their potential solutions are expected from all the stakeholders including operators, hardware vendors, scientific/academic community and administration. It is expected that 5G technology will help in creating a universally connected world with uninterrupted access to information, communication and entertainment.
