Implementation of Web AR Applications with Fog Radio Access Networks Based on Openairinterface Platform

Augmented Reality (AR), is a technology that gives you an interactive experience of the real world where the objects reside in are `augmented' by computer-generated perceptual information. Though some AR applications already exist on our smart devices, their development is not as promising as expected due to the requirement of the installation of a dedicated app. Hence the application of AR on large scales has been hampered to a certain extent. The advent of Web AR is a good complementary of the original in-app AR applications. With the convenience and cross-platform characteristics of Web browser, Web AR is being paid increasingly attention from both manufacturers and researchers. Fog Radio Access Networks (F-RAN) architecture takes full advantage of the storage and processing capabilities in edge devices, which significantly alleviates the burden of the fronthaul and BBU pool and reduces the transmission delay. Openairinterface is an LTE-compatible open source platform provided by Openairinterface Software Alliance (OSA). It is a promising demonstration platform, on which many new system architectures and communication technologies can be deployed. In this article, two applications of Web AR, including Web Face AR and Web Space AR, are successfully demonstrated on our F-RAN hardware platform based on Openairinterface. Performance evaluation results validate that they can provide users with good Quality of Experience (QoE) and very low latency.
