UAV Stereoscopic Video Streaming: Experimental Wi-Fi Bandwidth Analysis and THz Scalability Assessment

Unmanned Aerial Vehicles (UAVs) increasingly employ stereoscopic video streaming for XR-oriented and mission-critical applications, imposing stringent bandwidth requirements. This work experimentally quantifies the bitrate generated by a UAV-mounted stereoscopic camera under realistic flight conditions and evaluates the sustainability of heterogeneous wireless technologies. By analyzing different codec (H.264, H.265), frame rate, and resolution configurations, the study derives effective bitrate profiles from network-level Wi-Fi measurements under mobility. Results show that, although H.265 improves compression efficiency, Wi-Fi quickly becomes a scalability bottleneck in multi-stereo and high-resolution scenarios, significantly reducing service availability. In contrast, mapping the same traffic profiles onto a THz communication regime demonstrates substantial capacity margins and full service availability. Overall, the study provides an experimental traffic characterization and a quantitative framework for assessing service availability, offering practical design guidelines for scalable multi-UAV XR systems and highlighting the enabling potential of THz communications for high-capacity aerial networks.
