The measurements of air-to-air channel at C-band for coexistence among multiple unmanned aircraft (UA) systems are presented. The measurement campaign was performed to clarify the channel characteristic of the air-to-air radio propagation between small UAs. This paper presents a measurement result of our campaign on radio channel characteristics in C-band held in Japan in March 2016. The received...
This paper presents a measurement setup for transport protocol of wireless relay network using a unmanned aircraft (UA). The UA can fly back and forth to ferry data from multiple ground based access points or ground stations (GSs) that are located in the distance without connection to the backbone due to the network disconnection caused by a large-scale disaster. In such disaster area, a demand of...
This paper presents a performance evaluation on path diversity introduced in a wireless network established by unmanned aerial vehicles or unmanned aircrafts (UAs). One of usage scenarios of the wireless network established by UAs is establishment of a temporal communications instead of disrupted terrestrial networks due to a massive disaster. In order to evaluate system performance based on this...
