发明名称 NARROW-BAND RADIO CONTINUOUS COMMUNICATION METHOD AND SYSTEM
摘要 <p>PROBLEM TO BE SOLVED: To provide a communication method for enabling reception of continuous communication through road side antennas disposed alternately for time- shared operation. SOLUTION: Road side antennas 101 and 102 are disposed alternately, such that the communication ranges overlap appropriately for time shared operation. A mobile unit 122 searches a receiving frame 133 from an adjacent next antenna 102, extending from a communication frame 131 via the antenna 101 used at the overlapping point. When communication can be received continuously, both communications can be transmitted/received by switching the antennas instantaneously.</p>
