Adaptive Video with SCReAM over LTE for Remote-Operated Working Machines

Figure 2

The setup consists of several pieces of network equipment at the remote-control station and the wheel-loader connected by a partially wired and partially wireless network (LTE). From a logical point of view, the 4G router in the wheel-loader connects to a router in the same building as the control station through a VPN tunnel via the backbone network of the service provider (Telia) and the Internet. The 4G base station router is connected to the gateway router for the control station equipment with a 600-meter-long fiber cable. The graphics PC handles the data from cameras and microphone, while the control PC sends the control packets to the wheel-loader and receives feedback data for moving the motion platform and plotting the HMI.
