Abstract

Two kinds of WLAN systems of 5GHz band and evaluated in experimental UAS, which consist of UAV and ground systems have been used. Relationship between distance and communication speed was not found in our experiments. Also, we showed relationship between moving speed and communication speed. Both WLANs available about 100km/h. We showed MIMO (802.11n) was better than SISO (802.11a) on average of communication speed. However, communication speed of SISO was more stable and better than that of MIMO in terms of the minimum communication speed. We also investigated heading angle dependecy. We found that communication speeds slow down when the UAV turns. More investigation was necessary in the detail why communication speed of MIMO systems had a large variance.
