On February 16, the Municipal Radio Administration organized technicians to rush to the interference site as soon as possible to investigate the interference. Due to the large interference range, the technicians used the portable spectrum analyzer PR100 to monitor the village on foot according to the characteristics of the rural interference area. The direction was measured at a higher position near Chuanxian Village, and it was found that the signal had a trend of increasing in the northeast direction. . Tracking on foot in this direction, it turned out that outside the fence of a farmyard, the signal suddenly became larger, and the noise floor of the base station operating frequency band was raised.
