Cutting the cord: key performance indicators for the future of wireless virtual reality applications

Abstract

The new generation of telecommunication networks (5G) are considered a key technology enabler for the future of Virtual Reality (VR) technologies. 5G improved throughput and low latency capabilities open the door for novel distributed VR architectures that will accelerate the development of wireless immersive VR. While the downlink requirements for wireless VR have been previously studied, the uplink transmissions have been completely neglegted. However, for the succesful consecution of a fully immersive wireless VR, the uplink stream becomes as important as the downlink. In this paper, we thoroughly analyze VR thecnologies state of art to extract an initial set of data flow and processing times requirements for a subgroup of identified key algorithms. Besides, we propose the peak throughput and latency requirements Key Performance Indicators (KPIs) estimation as a simple optimization problem, given the data gathered in the state of the art analysis. Finally, we propose a set of valid ranges of peak throughput and latency requirements for a selected group of three different offloading scenarios.
