Abstract (in Japanese) (See Japanese page) 
(in English) Usecase of Wireless Power Transfer (WPT) system becomes wider because of its convenience. 920MHz, 2.4GHz, 5GHz bands are applied for WPT. Especially, it is concerned about some interference between WPT and Wi-Fi, because 2.4GHz and 5GHz WPT bands are near from 2.4GHz and 5GHz wireless LAN (Wi-Fi) bands. It is important to observe frequency spectrum of these bands. We have developed a simple real-time and broadband spectrum monitor using different undersampling frequency and simple “AND” algorythm for Wireless IoT bands including Wi-Fi bands. We try to regenerate RF-spectrum by using these methods for measured 2.4GHz and 5GHz WPT signals and measured psuedo Wi-Fi signals using signal generator in anechoic chambers as a basic study of developping spectrum monitor for expanded observation bands including WPT. We succeed to obtain both WPT(2.4GHz) and Wi-Fi(2.4GHz), both WPT(5GHz) and Wi-Fi(5GHz) spectrums.
