On the Way to Holographic-Type Communications: Perspectives and Enabling Technologies

Abstract

Holographic-type communication (HTC) is on the verge of revolutionizing current communication paradigms. It will seamlessly connect people from distant locations through a fully immersive experience that will engage all five senses: sight, hearing, touch, smell, and taste. However, the practical realization and widespread adoption of HTC impose significant demands on current networks and enduser devices. While recent studies have primarily focused on discussing the HTC challenges and potential research directions, this paper takes a further step by evaluating the capabilities of wireless networks to meet HTC requirements. Specifically, it highlights the limitations of the fifth-generation (5G) networks by identifying HTC-related Key Performance Indicators (KPIs) and explores the potential of the sixth-generation (6G) networks. Moreover, it not only proposes potential research approaches for HTC enhancement but also analyzes their impact on the challenges in HTC implementation. Finally, the paper questions the ubiquitous potential of 6G, suggesting that a coordinated approach leveraging artificial intelligence (AI) for jointly optimizing user sites and communication networks is the most promising strategy, rather than solely relying on the capabilities of specific network generations.

Low-Polarization, Broad-Spectrum Semiconductor Optical Amplifiers

“…According to publicly available data from the Ministry of Industry and Information Technology of China, the cumulative mobile internet traffic in China reached 3015 billion GB in 2023, a 228-fold increase over the past decade. Future applications of 6G networks will further focus on 3D immersive experiences, including augmented reality, smart interactions, holographic communication, digital twins, and other new applications, which pose significant challenges to the transmission capacity and speed of optical fiber communication systems, accelerating the upgrade of optical networks [ 3 , 4 , 5 ].…”
