Abstract

We report on propagation tests carried out in a subterranean tunnel to support improved wireless communications for urban search and rescue robots. We describe single-frequency and ultrawideband channel-characterization tests that we conducted, as well as tests of telemetry and control of a robot. We utilize propagation models of both single-frequency path loss and channel capacity to predict robot performance. These models can also be used for optimizing wireless communications in tunnels of various sizes, materials, and surface roughness.
