This research addresses the limitations of the current wireless network due to fixed spectrum assignment, leading to inefficient spectrum usage and network congestion. By exploring Cognitive Radio, an innovative communication paradigm, the study seeks to enhance the network's functionalities and overcome existing challenges comprehensively. Cognitive Radio introduces intelligence, allowing the network to adapt dynamically, optimize spectrum usage, and handle higher traffic demands efficiently, resulting in improved customer experience and increased revenue for network providers. The integration of Cognitive Radio into the 4G network through Matlab simulation offers promising results, with slight increases in the Call Setup Success Rate (CSSR) ranging from approximately 0.84% to 1.55% for individual sites. Additionally, the Drop Call Rate has significantly decreased by approximately -17.96% to -60.00% for different sites, indicating improved call stability and user satisfaction. Overall, the study demonstrates the potential of Cognitive Radio to transform the wireless network into a more adaptive and intelligent system, catering better to the growing demands of modern mobile communication.
