<P>PROBLEM TO BE SOLVED: To provide a radio communicating system and a program, which reduce the electric power consumption of a radio terminal device upon setting the information of a frequency capable of communicating with a radio relay device, in the radio terminal device. <P>SOLUTION: A setting device 20 stores a radio relay device identifier capable of identifying a radio relay device 40, and frequency information for permitting the radio terminal device 30 to communicate with the radio relay device 40 in a memory unit 22 after correlating them, and determines the strength of radio wave by receiving the radio wave, outputted from the radio relay device 40 together with the radio relay device identifier, then, obtains from the memory unit 22 the frequency information related to the radio relay device identifier included in the radio wave determined as high in the radio wave strength to output the same through the radio wave. On the other hand, the radio terminal device 30 controls so as to effect reception at a frequency stored in the memory unit 33 after detecting the turning-on of the power supply to the device 30 and receives radio wave including the frequency information transmitted from the setting device 20 to store the frequency information into the memory unit 33. <P>COPYRIGHT: (C)2009,JPO&INPIT |
