Wireless Access to Ultimate Virtual Reality 360-Degree Video

Virtual reality 360-degree videos will become the first prosperous online VR application. In this paper, we focus on the ultimate VR 360 that satisfies human eye fidelity. The ultimate VR 360 requires downlink 1.5 Gbps for viewing and uplink 6.6 Gbps for live broadcasting, with the round-trip-time of less than 8.3 ms. We explore whether the most advanced wireless communication technologies support the ultimate VR 360. Specifically, we consider 5G in cellular communications, IEEE 802.11ac (operating in 5 GHz) and IEEE 802.11ad (operating in 60 GHz) in WiFi communications. Our results indicate the need for more advanced wireless technologies to fully support the ultimate VR 360. It requires further research to build VR 360 systems within Internet-of-Things platforms.
