Evaluating Latency in a 5G Infrastructure for Ultralow Latency Applications = Evaluating Latency in a 5G Infrastructure for Ultralow Latency Applications

It’s predicted that 5G, the fifth generation of mobile network, would be commercially available worldwide shortly as 5G currently deployed has limited coverage. There will be a substantial boost in performance and reliability compared to the current generation - 4G mobile network. The packet latency of 5G is roughly ten-fold less than that of existing 4G networks. For several applications of 5G, packet latency must be at about one millisecond. For emerging new services such as virtual reality (VR), live streaming using mobile networks, autonomous vehicles, and tactile Internet with the capability of machines and equipment remote operation and high sensitivity via mobile network, significantly low latency is required. With my thesis, I have attempted to understand how real-world variables impact packet delay. The lack of comprehensive research on the particular aspects affecting packet delay in a 5G network in a realistic condition in contrast with laboratory conditions can be observed, where the reported packet latency would be pretty low. Several elements impact packet delay in a practical 5G network, and the outcome of this research has helped to recognize them. To determine how each part contributes to overall packet delay, this information is collected. The future extension of this study can be testing the 5G network’s latency reduction methods effectiveness. Identifying how 5G network packet latency is caused and affected was required before reducing packet latency to meet 5G latency objectives. To reach this aim, this effort was undertaken. It was determined that a 4G network’s lower latency improvement threshold was achieved by evaluating the latency reduction strategies in their optimal configuration. Therefore, to meet 5G latency objectives, 4G radio access and core network technology must be changed to reach 5G latency targets.
