Demo of the Phase Tracing interface on CloudRF using an iPad Pro.
The glTF tunnel model was uploaded into the interface and a 450MHz radio placed at one end of the tunnel.
The simulation parameters used high resolution (25cm), high reflections (18) and high density (60dB/m) to simulate reflections along the tunnel.
As you can see it's not pretty once reflections occur and signals collide out of phase. This multi-path effect limits radio communications in tunnels severely. Another tunnel issue is doppler spread from reflections which causes signals to move in frequency and bandwidth.
