Enhancing Quality of Service for Streaming Data Transmission on 6G Networks with Reconfigurable Technology

This article explores how reconfigurable intelligent surfaces (RIS) can enhance the quality of service (QoS) for streaming data transmission over 6G networks operating at 300 GHz. The focus is on reliability, latency, and throughput in both line-of-sight (LoS) and non-line-of-sight (NLoS) scenarios.

By programmatically shaping the propagation environment, RIS can significantly improve the NLoS signal-to-noise ratio (SNR), reduce bit error rates (BER), shorten packet delays, and increase throughput. This technology aims to meet the stringent requirements of ultra-reliable low-latency communication (URLLC) for emerging 6G applications.

The research in this paper includes noise power, path loss, RIS array gain, capacity, BER, and SNR-dependent latency relations. The study also introduces coding-aware BER and an improved 300 GHz channel model considering atmospheric absorption for more realistic results.

RIS technology provides a robust solution for high-frequency propagation challenges by enhancing SNR, reducing errors, and improving latency. By integrating RIS into 6G networks, we can create a programmable propagation channel that enables efficient communication for various applications like holographic communications, industrial automation, and extended reality.

Overall, RIS technology shows promise in revolutionizing 6G networks by addressing connectivity challenges in NLoS and high-path-loss environments. It offers a new approach to managing QoS requirements for emerging applications through intelligent manipulation of wireless propagation.
