Identifying QOS impacts on the 4G LTE and 5G FWA integration using 2300 to 2400 MHz band reallocation for high-speed internet alternative to traditional fiber

Although 5G technology has been in development for a considerable time, significant challenges regarding its effective implementation still need to be addressed. A key issue lies in using frequency and ensuring coexistence with previous technologies that continue to serve existing users because users in many countries' late adoption of new technologies does not always progress smoothly. This research paper aims to evaluate 5G Fixed Wireless Access (FWA) utilizing the 2300 to 2400 MHz spectrum that is usually used in 4G LTE previous technology, positioned as a viable alternative to traditional fiber optic networks, and its impact on technology valuation in spectrum usage to solve high-speed alternative traditional fiber in rural and urban areas. The study focuses on Quality of Service (QoS) related to user experience with a standard wireless access service parameter while analyzing payload growth and revenue generation improvements compared to LTE technologies. Through rigorous trials, our results demonstrate that 5G FWA not only preserves the QoS experienced but significantly enhances it as a feasibility analysis of network productivity by combining 4G and 5G technology in one service area. The implementation trial of 5G FWA resulted in notable increases of 50 % in more than 20 Mbps data throughput, contributing to 27 % substantial growth in payload and revenue in an area using only 4G LTE before 5G FWA was implemented. By providing detailed performance metrics, the trials highlighted the potential for 5G FWA to deliver broadband services more efficiently and cost-effectively, particularly in regions where geographical or economic factors constrain the expansion of fiber optics.
