摘要： A mobile information terminal has a front surface on which a display surface of a display device is arranged and a rear surface on which a plurality of operation keys are arranged. The mobile information terminal further has a half-depressing sensor for detecting that each of the operation keys is half-depressed and/or a touch sensor for detecting that each of the operation keys is touched. A control section executes a processing operation to cause the display device to display an image showing the arrangement of said operation keys and to change an icon which corresponds to a key of operation keys when a control section determines, according to an input signal from the half-depressing sensor or the touch sensor, that the finger of the operator is placed on this key of operation keys.

摘要： Provided is a mobile wireless communication system that improves response immediacy in a wireless communication system using an SCPC communication system. For this purpose, a base station and/or a plurality of mobile stations is provided with a number-of-channels switching means that monitors the communication state to create determination information for determining the necessity of switching the number of channels, and that switches the ratio of the number of channels for downlink communications and that for uplink communications, in a case where a change in the number of channels is necessary on the basis of the determination information.

摘要： A wireless communication system includes a base station and direct wave communication stations that communicate with the base station. At least one of the base station and the direct wave communication stations includes a number-of-bands switching unit that switches, on the basis of a communication state, a number of bands for direct wave communication, by dividing a band for direct wave communication. One of the plurality of direct wave communication stations receives a narrowband carrier in the divided band.
