Abstract:: Holographic communication is a disruptive technology in the field of data sharing, allowing for near-contact 3D representations that can be interacted with in real-time across a wide range of domains, from medicine and engineering to immersive media. Despite their potential, the practical implementation of computer-generated holography (CGH) is still limited by demanding network constraints, especially in the aspects of latency, bandwidth and image fidelity. We deliver a comparative performance analysis of CGH transmission in two wireless network environments: latest 4G LTE and pure 5G New Radio (NR). Using a defined experimental design including duplicate runs of holographically identical content and rendering settings. Individual key performance metrics – one-way latency, throughput, and visual quality – were measured and normalized to create a composite performance index. Results show that 5G NR consistently and significantly outperforms in all other scenarios with an average reduced latency of 84.84%, throughput increased by 6.14× and image quality scores across all experiments. Using network slicing and edge computing in simulations also lowered latency under ideal 5G conditions. These results verify that 5G NR satisfies as well as outstrips the performance limits if you want to real-time CGH, and thus represent a solid base for broadcasting holographic applications on a large scale. The results of this work will serve as empirical data for strategic inclusion of 5G in future holographic system and provide insights on how advanced network configurations will translate into better performance reliability, scalability, and user experience.
