The algorithms for augmented reality (AR) applications, which are used to insert virtual objects in the real world, have been continuously improved in recent years. Software development kits (SDKs) for the mobile operating systems Android and iOS have been published which allow the usage of AR without markers. The complete rendering, as well as the tracking, are executed on the smartphone. Therefore, the graphical quality is limited. With remote rendering, large parts of the rendering can be transferred to a server. In this paper, a remote rendering system for an AR app based on Unity is presented. The system was implemented for an edge server, which is located within the network of the mobile network operator. Our evaluation shows that the system achieves better average frame times, even when the application is running for a longer time period. Furthermore, the graphical fidelity is improved compared to pure mobile rendering.
