Underground environments present their unique challenges for wireless communication. This paper presents an empirical study of WiFi performance where aerial-ground robots are used to map, navigate, and search in an unknown underground environment. While wireless signal attenuates significantly around corners, WiFi's overall performance is encouraging.
