摘要： A communication system includes a roadside unit and a mobile communication unit that communicates with the roadside unit by using one of a plurality of communication channels. The mobile communication unit obtains, for each communication channel, a reception condition measurement representing the reception condition of a radio signal received from the roadside unit, creates information of a candidate channel for a receiving channel to be used to receive the radio signal from the roadside unit, and reports the candidate channel information to the roadside unit. On the other hand, the roadside unit assigns the receiving channel by selecting it from among the candidate channels, and reports the receiving channel to the mobile communication unit.

摘要： A wireless communication system is provided with a wireless transmission apparatus and a wireless reception apparatus. The wireless transmission apparatus includes a plurality of transmission antennas and a transmission unit. The transmission unit performs signal transmission according to a notified operation mode. The wireless reception apparatus includes a plurality of antennas, a reception unit, a reception quality controller, and an operation mode controller. The reception unit performs reception processing of reception signals received by the reception antennas. The reception quality controller measures a reception quality of each reception signal to calculate a ratio of the reception quality. The operation mode controller determines selection or non-selection of an operation mode according to a comparison result of the ratio and a threshold value and gives notification of the selected operation mode.

摘要： A switch module including a light source element is provided that obtains slimming down and a sufficient click feeling and suitably irradiates a key portion, while suppressing manufacturing cost. A switch module is disposed to face a key portion. The switch module includes a transparent FPC board, a transparent conductive film, an electrode, a metal dome which is in contact with a part of the transparent conductive film and which is allowed to come into contact with the electrode by being deformed, and an LED. Light emitted from the LED and guided in a direction orthogonal to a thickness direction of the board in the transparent FPC board is reflected by a reflecting portion provided on the transparent FPC board, in a direction of the key portion.
