1. A radio communication equipment comprising: a sending and receiving unit configured to send and receive data to and from other radio stations by radio signals, anda data processing unit configured for processing sending and receiving data and conducting an operation control of said sending and receiving unit,a control unit configured to output a sending timing signal and receiving timing signal at a fixed interval;a radio signal intensity measuring unit configured to measure an intensity of a radio signal of a radio channel when said sending timing signal or said receiving timing signal is given;a decision unit configured to compare the measured radio signal with a predetermined threshold level, based on a measuring control signal, a receiving control signal, and a sending control signal, being given from a timing control unit, andwherein said timing unit is configured to generate said measuring control signal, said receiving control signal and said sending control signal based on a fixed range;based on said comparison, said decision unit configured to output a sending enabling signal when said measured radio signal has an intensity less than a predetermined threshold level, and to output a receiving enabling signal when said measured radio signal has an intensity greater than the predetermined threshold level;a modulation unit configured to modulate sending data from said data processing unit and output the data thereof, when said sending enabling signal is given;a demodulation unit configured to demodulate received data and to generate receiving data, when said receiving enabling signal is given; anda receiving control unit configured to provide a demodulation enabling signal to said demodulation unit when said receiving enabling signal is given, to decide whether or not said receiving data generated in said demodulation unit are correct, and to output said receiving data to said data processing unit when said receiving data are correct and to stop said demodulation enabling signal when said receiving data are not correct,wherein said data processing unit is configured to be activated by said sending enabling signal, to output said sending data to said sending and receiving unit, to be activated by said receiving signal, and to input said receiving data from said receiving unit. 2. The radio communication equipment according to the claim 1, further comprising a power saving control unit configured to control a clock supply and power supply to said sending and receiving unit, being directed said sending timing signal, receiving timing signal, said sending enabling signal, said demodulation enabling signal, and said operation mode control signal from said data processing unit. 3. A radio communication method, comprising: sending and receiving data to and from radio stations by radio signals, andprocessing sending and receiving data; and conducting an operation control of said sending and receiving data;outputting a sending timing signal and a receiving timing signal at a fixed interval;measuring an intensity of a radio signal of a radio channel when said sending timing signal or said receiving timing signal is given;comparing the measured radio signal with a predetermined threshold level, based on a measuring control signal, a receiving control signal, and a sending control signal generated based on a fixed range;based on said comparison, outputting a sending enabling signal when said measured radio signal has an intensity less than the predetermined threshold level, and outputting a receiving enabling signal when said measured radio signal has an intensity greater than the predetermined threshold level;modulating sending data and outputting the data thereof, when said sending enabling signal is given;demodulating received data and generating receiving data, when said receiving enabling signal is given; andproviding a demodulation enabling signal when said receiving enabling signal is given,deciding whether or not said receiving data generated are correct, and outputting said receiving data when said receiving data are correct and to stop said demodulation enabling signal when said receiving data are not correct;outputting said sending data when said sending enabling signal is given; and inputting said receiving data when said sending enabling signal is given. 4. The radio communication method according to claim 3, further comprising halting the sending operation when the measured radio signal intensity is greater than the stored value in the sending timing. 5. The radio communication method according to claim 4, further comprising halting the receiving operation when the measured radio signal intensity is smaller than the stored value in the receiving timing.
