The rapid adoption of 5G revolutionized connectivity worldwide, enabling faster data transfer along withthe support of a variety of use cases. However, next-gen technologies demand higher performance, as the limitations of 5G become increasingly apparent. The 6G network transition is approaching but comes with unique challenges, particularly with spectrum management, security, and data transmission. The present research considers the most significant challenges that must be addressed for a smooth and successful 5G-6G transformation to occur. Based on case studies and academic literature, the research employs a comparative approach and statistical analysis to evaluate 5G limitations and assess the innovative potential of 6G. The envisioned contribution is the identification of the most significant technical, regulatory, and security vulnerabilities, along with proposed solutions. Through these alternatives, the research will help to identify 6G networks that are secure, resilient, and applicable globally for use and additional critical infrastructure support.
