Toward Low-Latency and Ultra-Reliable Virtual Reality

TLDR

Virtual Reality is poised to be a flagship application of 5G, yet its adoption is hindered by technical bottlenecks requiring high throughput, low latency, and reliable communication. The article examines the challenges and enablers needed to achieve ultra‑reliable, low‑latency VR. A case study demonstrates that a network design combining mmWave, edge computing, and proactive caching can realize ultra‑reliable, low‑latency VR over wireless.

Abstract

Virtual Reality (VR) is expected to be one of the killer-applications in 5G networks. However, many technical bottlenecks and challenges need to be overcome to facilitate its wide adoption. In particular, VR requirements in terms of high-throughput, low-latency and reliable communication call for innovative solutions and fundamental research cutting across several disciplines. In view of this, this article discusses the challenges and enablers for ultra-reliable and low-latency VR. Furthermore, in an interactive VR gaming arcade case study, we show that a smart network design that leverages the use of mmWave communication, edge computing and proactive caching can achieve the future vision of VR over wireless.
