The impact of noise from the CPU board on mobile communication and identification of the noise source

Abstract (in Japanese) (See Japanese page) 
(in English) Various robots (autonomous mobile devices) are beginning to be used in our daily lives. Even if the radio noise from a single autonomous mobile device is small, their widespread use can affect wireless communications. We investigated the source of noise in wireless communications from autonomous mobile devices and found that it mainly originates from around the CPU board. Measurements of a mini PC with the same structure as the CPU board built into an autonomous mobile device revealed that it affected IEEE802.11ah wireless communications in the 920 MHz band. This paper explains the results of measurements of the impact on mobile phones (LTE, 5G) using the same method.
