Investigation Carrier Aggregation in 4G LTE and 5G NR Networks

 Carrier aggregation technology provides a significant enhancement to wireless communication networks by enabling the amalgamation of multiple LTE or NR component carriers, thereby increasing bandwidth capacity, improving data rates, and enhancing the overall user experience. This technology plays a key role in both 4G and 5G networks, optimizing spectral efficiency and network performance. This paper explores the fundamentals of carrier aggregation, its implementation in 4G and 5G networks, and the challenges and future directions associated with this technology. Experimental results, case studies, and analysis are presented to evaluate the impact of carrier aggregation on key performance metrics and network efficiency.
