PURPOSE:To improve the working efficiency of a frequency channel by finding the working ratio of the frequency channel in advance, and selecting the frequency channel with low working ratio when communication is performed newly. CONSTITUTION:The input/output of a transmitter/receiver 1 and a storage device 3 are connected to an arithmetic and control unit 2. In such a case. the transmitter/receiver 1 can perform transmission/reception with another radio communications equipment by using one of plural frequency channels, and the arithmetic and control unit 2 performs the control of the transmitter/ receiver 1 and the arithmetic operation of the working ratio of the frequency channel in use at present, etc. Also, the storage device 3 stores the working ratio of the frequency channel computed by the arithmetic and control unit 2. The arithmetic and control unit 2 transmits the working ratio stored in advance in the storage device 3. respectively when the working ratio of the frequency channel is inquired from the radio communications equipment which performs the communication newly. The arithmetic and control unit 2 selects the frequency channel with low working ratio by comparing the size of received working ratios. |
