Analysis of Uplink Performance of 5G mm-Wave Networks in Contrast to 4G Networks

5G, the latest wireless communication network, offers high-speed data transmission capabilities and is known as New Radio (NR). It serves as an extension of 4G technology. The main objective of this research is to analyze the physical layer of 5G NR and 4G Long Term Evolution (LTE) using MATLAB 2020a. In this context, the study evaluates the performance of 4G and 5G in the uplink cell, focusing on metrics such as Throughput, Spectral Efficiency, Latency, and Block Error Rate (BLER). It also highlights the differences between 4G LTE and 5G NR. Notably, 5G outperforms 4G in various aspects: it achieves a spectral efficiency of 25 bps/Hz, while 4G only manages 2.52 bps/Hz. Throughput for 5G shows a 5% improvement over 4G (considering 300 frames). The latency in 5G is reduced to less than 0.1ms compared to 4G, and the Block Error Rate has decreased from 0.02 to 0.01. These findings illustrate that 5G offers a wide range of services with high data rates, extensive coverage, reduced latency, increased system capacity, and enhanced user connectivity across the board.
