Abstract (english): 
This paper introduces Wireless Compose-2 (WICO2), which is an experiment for the International Space Station (ISS) in order to demonstrate the provision of a flexible and adaptable wireless network infrastructure integrated into a commodity item to conduct and execute low-power, low-weight and wireless experiments in the scientific and medical domain. Recent work revealed a great potential in utilizing Wireless Sensor Network (WSN) in space habitats; however, the focus was only placed on sensing in the narrowband Industrial Scientific and Medical (ISM) 2.45 GHz band. This work extends these capabilities by utilizing Impulse Radio Ultra Wideband (IR-UWB) for ranging and evaluates the use of internal light sources for energy harvesting to drive the sensor nodes. The focus of the WICO2 experiment is on the operation of the scientific experiment Ballistocardiography for Extraterrestrial Applications and long-Term missions (BEAT), which is a demonstration of novel Ballistocardiography (BCG) sensors to monitor important cardiovascular parameters in a microgravity environment. Integrated in a Smart-Shirt, it will form a Body Area Network and make use of the IR-UWB communication to transmit the data to the network. This paper describes the concept and pre-flight test results to demonstrate the correct function, usability and performance of WICO2.
