<p>A mobile communication system comprising communication equipment provided on the fixed side and communication equipment provided on the mobile side. The mobile communication equipment starts to operate when its whole circuit is powered in response to a start signal from the fixed communication equipment. The mobile equipment modulates the electromagnetic waves radiated from the fixed communication equipment and returns the response, in order to continue the bidirectional communication of instructions and data. When it is detected by entrance detect means that the mobile communication equipment has entered a favorable communication range, communication is started between both sides by direct waves in the microwave band, to reliably carry out the communication maintaining sufficiently strong electromagnetic wave intensity.</p> |
