SYSTEM FOR PERFORMING TIME-DELAY TRANSMISSION OF RADIO FREQUENCY SIGNAL AND CONTROL METHOD THEREOF

摘要

PURPOSE: A radio wave delaying system and control method thereof are provided to transmit a signal by delaying a communication RF(Radio Frequency) signal transmitted by a portable terminal from each analog optical relay apparatus. CONSTITUTION: A radio wave delaying control apparatus(110) relays communication between a base station(300) and an analog first optical relay apparatus(210). A radio wave delaying apparatus(120_1~120_N) are connected with analog second optical relay apparatuses(220_1~220_N). The radio wave delaying apparatus delays an RF communication signal received from the analog second optical relay apparatus during a time established by the radio wave delay control signal of the radio wave delaying control apparatus.
