Cutting the Cord: Key Performance Indicators for the Future of Wireless Virtual Reality Applications
Diego González Morín, Ana García Armada, Pablo Pérez · 2020
The new generation of telecommunication networks' (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. In this paper, we study both the uplink and downlink requirements for a successful implementation of a fully immersive wireless VR. We thoroughly analyze VR technologies state of art to extract an initial set of data flow and processing times requirements for a sub-group 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. Using this optimization problem, we determine a set of valid ranges of peak throughput and latency requirements for a selected group of 3 different offloading scenarios. Finally, we present different radio access configurations that fulfill such requirements.
