Summary:Despite the fact that cave communication has an abundant history, when an accident happened, some of the major problems are seemed to be left untreated yet. A year ago, thousands of people from around the world gathered in Thailand to help rescue one Thai soccer team who was trapped inside a cave. Tragedy could be avoided or better resolved with wireless communication inside cave. In this work, we have built an uneven terrain model for potential applications in cave environment since the ground in cave is oftentimes not flat but uneven. We performed field measurement on this uneven terrain model at 2.4 GHz. Subsequently, the measured result is compared with two ray-tracing results - one original one and another one with a scattering factor incorporated. The comparison shows that the latter ray-tracing simulation matches the measured result better, with an improved standard deviation value.
