Development and Application Prospects of 5G Communication Technology

Abstract

The rapid development of information and communication technologies has significantly reshaped economic and social structures, with 5G emerging as a key driver of digital transformation. This paper examines the evolutionary trajectory and application prospects of 5G communication technology, shedding light on its technical underpinnings, challenges, and potential solutions. The study addresses the research problem of how 5G can balance performance improvements with limitations in spectrum resources, network security, and energy consumption. By analyzing core technologies such as massive MIMO, millimeter-wave transmission, and network slicing, this paper demonstrates how 5G supports applications across smart cities, remote healthcare, industrial automation, and autonomous driving. Case studies drawn from China’s 5G commercial deployment further illustrate the transformative impact of this technology. The conclusion emphasizes that while 5G accelerates digitalization and intelligent connectivity, future research must focus on sustainable, secure, and efficient pathways toward 6G development.
