| Abstract(in English) | In order to quantitatively evaluate the radio environment at the altitude at which UAV fly, we have been measuring the radio environment in the sky using SDR mounted on UAV. In this report, we describe the results of radio environment measurements in the rural area. We measured in the 920 MHz, 2.4 GHz, and 5.7 GHz bands and evaluated them by Maxhold, spectrogram, and cumulative relative frequency distribution. As a result, we detected a signal that seemed to be a wireless LAN in the 2.4 GHz band at an altitude of 100 m and 145 m around a residential area, but the signal was weak and thus had little effect on the UAV communication. |
