An electronic device detects an object reflecting transmitted waves based on transmitted signals transmitted as the transmitted waves from transmitting antennas and received signals received from receiving antennas as reflected waves obtained by reflection of the transmitted waves. The electronic device determines that the object have been detected when the peak in the result obtained by performing a Fourier transform process on the beat signals generated based on the transmitted and received signals is equal to or higher than a predetermined threshold value. The electronic device sets a predetermined threshold value based on an object detection probability.

Electronic device, method for controlling electronic device, and electronic device control program

An electronic device includes a controller that performs control to enable switching between a first band mode such that a transmission wave is in a first band and a second band mode such that the transmission wave is in a second band broader than the first band. The controller performs control to switch to the second band mode when an object is detected within a predetermined distance in the first band mode.

Electronic device, control method of electronic device, and control program of electronic device

In a base station deviceof an OFDMA mobile communication system, a frequency band storage unitstores multiple frequency bands allocatable to mobile station devices, respectively, in association with predetermined conditions related to communication quality. A communication quality acquisition unitacquires communication quality in communication with each of the mobile station devices. A frequency allocatorselects any one of the frequency bands from the frequency band storage uniton the basis of the communication quality acquired by the communication quality acquisition unit, and notifies the mobile station device of channel information indicating the selected frequency band. Then, the mobile station device communicates with the base station devicein the frequency band indicated by the channel information notified by the frequency allocatorin the base station device
